How and When to Invoke Appraisal in California: A Practitioner's Guide

Insurance appraisal is one of the most powerful tools available to a policyholder who has been underpaid on a property insurance claim. But it is also one of the most misunderstood. When should you invoke it? What happens if the umpire goes rogue? Can you still sue for bad faith after receiving an award? What do you do when the insurer interferes with the process?

This article is a practitioner’s guide — written for public adjusters, attorneys, and sophisticated policyholders who need to understand not just how appraisal works in theory, but how to navigate the real-world problems that arise when the process is invoked. For the foundational case law, see our companion article on Key California Insurance Case Law.

I. The Basics: What Is Appraisal and Where Does It Come From?

A. The Statutory Basis: California Insurance Code § 2071

The right to appraisal in California is not merely contractual — it is statutory. California Insurance Code §§ 2070–2071 prescribe the California Standard Form Fire Insurance Policy, which every fire insurance policy issued in the state must contain or incorporate. Section 2071 includes a mandatory appraisal provision:

“In case the insured and this company shall fail to agree as to the actual cash value or the amount of loss, then, on the written request of either, each shall select a competent and disinterested appraiser and notify the other of the appraiser selected within 20 days of the request. Where the request is accepted, the appraisers shall first select a competent and disinterested umpire; and failing for 15 days to agree upon the umpire, then, on request of the insured or this company, the umpire shall be selected by a judge of a court of record in the state in which the property covered is located. The appraisers shall then appraise the loss, stating separately actual cash value and loss to each item; and, failing to agree, shall submit their differences, only, to the umpire. An award in writing, so itemized, of any two when filed with this company shall determine the amount of actual cash value and loss.”

This language is mandatory. The insurer cannot remove the appraisal provision from the policy — it is required by statute. Every California homeowner, renter, and commercial property policyholder has a statutory right to appraisal when the dispute is about the amount of loss.

B. The Relationship to Arbitration Law: CCP § 1280 et seq.

Appraisal is not formally “arbitration,” but California courts have consistently held that it is a quasi-arbitration proceedingsubject to the protections of the California Arbitration Act (Code of Civil Procedure § 1280 et seq.). This has several important practical consequences:

• Confirmation:An appraisal award can be confirmed by the court under CCP § 1285, giving it the force of a judgment.
• Vacation:An appraisal award can be vacated under CCP § 1286.2 on the same narrow grounds that apply to arbitration awards: corruption, fraud, or other undue means; evident partiality of the umpire; misconduct that substantially prejudiced a party’s rights; the panel exceeding its powers; or the panel’s refusal to hear material evidence.
• Disclosure:The umpire is subject to the disclosure requirements of CCP § 1281.9, which require disclosure of any grounds for disqualification, including financial interests and prior relationships with the parties. As established in Sharma v. USAA, failure to make required disclosures is itself a ground for vacating the award.
• Judicial review: Courts can intervene to appoint an umpire when the parties or appraisers cannot agree, and can review the process for procedural irregularities.

The arbitration framework gives appraisal awards their enforceability. Without it, appraisal would be merely advisory. With it, an award properly obtained is binding and carries the weight of a court judgment once confirmed.

C. Policy Provisions vs. Statutory Requirements

Although Insurance Code § 2071 mandates the appraisal provision, actual insurance policies frequently contain appraisal clauses with differentwording. Some policies impose conditions not found in the statute — for example, requiring that the demanding party pay the umpire’s fees upfront, imposing shorter timelines, or adding prerequisites to invoking appraisal.

When the policy language conflicts with the statutory language, the statute controls. The California Standard Form Fire Insurance Policy is a floor, not a ceiling. The insurer can provide more favorable terms, but it cannot take away what the statute guarantees. If your policy imposes conditions on appraisal that are more restrictive than § 2071, those conditions may be unenforceable.

II. Before Invoking Appraisal: Necessary Prerequisites

Appraisal is a powerful tool, but invoking it at the wrong time — or without proper preparation — can backfire. Before demanding appraisal, several prerequisites should be satisfied.

Establish Coverage First

As established in Kacha v. Allstate, appraisal determines the amount of loss, not coverage. This means that before appraisal is appropriate, coverage must be established. If the insurer has denied coverage entirely — or if there is a genuine dispute about whether the policy covers the loss — appraisal is not the right mechanism. Coverage disputes must be resolved through negotiation, regulatory complaint, or litigation.

In practice, this means you should not invoke appraisal until the insurer has accepted coveragefor the loss (even if it disputes the amount) or until the coverage issue has been resolved. Invoking appraisal on a claim where coverage is disputed risks having the panel issue an award on damage the insurer never agreed was covered — an award the insurer will then challenge as exceeding the panel’s authority.

Submit a Complete Proof of Loss

Before demanding appraisal, you should have submitted a complete proof of loss documenting the full scope and value of the damage. This serves multiple purposes: it establishes the policyholder’s position on the amount of loss, it satisfies the contractual condition precedent for appraisal (the parties must have “failed to agree” on the amount), and it creates a record that defines the parameters of the dispute.

A proof of loss that is vague, incomplete, or unsupported weakens your position going into appraisal. The proof of loss should be detailed, itemized, and supported by documentation — contractor estimates, Xactimate reports, photographs, and any other evidence of the loss. The stronger the proof of loss, the stronger the foundation for your appraiser’s position.

Document the Dispute in Writing

The statutory language requires that the parties “fail to agree” before appraisal can be invoked. This means there must be a documented dispute. Before demanding appraisal, you should have correspondence establishing that: (1) the policyholder has submitted a claim for a specific amount; (2) the insurer has responded with a lower amount or a partial denial; and (3) the parties have been unable to resolve the difference through negotiation.

This written record is important not only for the appraisal itself but also for any subsequent litigation. If the insurer later claims that appraisal was premature or that the dispute could have been resolved through further negotiation, your correspondence demonstrates that the dispute was real, documented, and unresolvable.

Allow the Insurer a Reasonable Opportunity to Respond

While there is no formal “waiting period” before appraisal can be invoked, demanding appraisal the day after filing a claim — before the insurer has had any opportunity to investigate or respond — may be premature. Courts expect the parties to have made a genuine attempt to resolve the dispute before resorting to appraisal. In most cases, the policyholder should have submitted a proof of loss, received the insurer’s response (or waited a reasonable time without response), and attempted to negotiate before invoking appraisal.

That said, there is no requirement that the policyholder negotiate indefinitely. If the insurer has taken a position that is clearly unreasonable, if the insurer is not responding to correspondence, or if the insurer has completed its investigation and issued a final payment that is far below the policyholder’s documented loss, appraisal may be appropriate.

Consider the Appraisal Memorandum

An appraisal memorandum is a document prepared by the policyholder (or their representative) that defines the scope of the appraisal — what items are in dispute, what the policyholder’s position is on each item, and what documentation supports that position. While not required by statute, an appraisal memorandum is a best practice for several reasons:

• It defines the scope of the appraisal and prevents the insurer from later arguing that certain items were not properly submitted.
• It provides the policyholder’s appraiser with a clear roadmap of the claim.
• It creates a record that distinguishes amount disputes (appropriate for appraisal) from coverage disputes (not appropriate for appraisal), consistent with Kacha.
• It establishes the policyholder’s position on causation issues, which can be critical in mixed-cause losses.
• If the appraisal is later challenged, the memorandum demonstrates that the process was conducted with appropriate scope and documentation.

III. Demanding Appraisal: Mechanics and Timing

The Written Demand

Appraisal is invoked by a written demandfrom either the insured or the insurer. The demand should be sent to the insurer (or to the policyholder, if the insurer is invoking) by certified mail or other verifiable method. The demand should clearly state that the party is invoking the appraisal provision of the policy, identify the claim at issue, and name the party’s selected appraiser.

Under Insurance Code § 2071, once a written demand is made, each party must select a “competent and disinterested appraiser” and notify the other party of their selection within 20 days of the demand. The demanding party typically names their appraiser in the demand letter itself.

Appraiser Selection: The 20-Day Window

After the demand is served, the responding party has 20 days to select and identify their appraiser. In practice, the insurer will typically name one of its preferred appraisers — often someone with a history of serving as the insurer’s appraiser in prior appraisals. The policyholder should select an appraiser who is experienced in property loss valuation, knowledgeable about the type of loss at issue, and willing to advocate for the policyholder’s position.

As established in Lambert v. Carneghi, the party appraiser is an advocate, not a neutral. The policyholder’s appraiser is expected to represent the policyholder’s position on the amount of loss. A licensed public adjuster is often the ideal choice, because they combine loss valuation expertise with advocacy experience.

Umpire Selection: The 15-Day Window

Once both appraisers are selected, they must agree on a “competent and disinterested umpire” within 15 days. The umpire is the neutral tiebreaker — if the two appraisers cannot agree on the amount of loss, they submit their differences to the umpire, and an agreement by any two of the three (both appraisers, or one appraiser and the umpire) determines the award.

Umpire selection is often contentious. Each side wants an umpire they believe will be sympathetic to their position, and the appraisers may have difficulty agreeing. Common approaches include exchanging lists of proposed umpires, using a strike-and-rank process, or agreeing on criteria (e.g., a retired judge, a licensed contractor, or an experienced appraiser with no ties to either party).

Court-Appointed Umpires

If the appraisers cannot agree on an umpire within 15 days, either party can petition the court to appoint one. Under § 2071, the umpire “shall be selected by a judge of a court of record in the state in which the property covered is located.” In practice, this means filing a petition in the superior court of the county where the property is located.

Court-appointed umpires are often preferable for the policyholder, because the court is more likely to select someone who is genuinely neutral rather than someone from the insurer’s preferred list. As Sharma v. USAAestablished, the umpire is subject to the disclosure requirements of CCP § 1281.9, and a court-appointed umpire who has undisclosed conflicts can be challenged.

Umpire Selection Strategy: The Most Critical Decision in the Process

The umpire will decide the outcome of every disputed item the appraisers cannot resolve between themselves. In practice, that means most of the disputed dollar amount. Your strategy for umpire selection should be at least as rigorous as your strategy for building the appraisal estimate itself.

Research potential umpires thoroughly.Before exchanging lists with the opposing appraiser, investigate every candidate’s background. What is their professional history — construction, adjusting, law, real estate? Have they served as an umpire before, and if so, what were the outcomes? An umpire who has a construction or property adjusting background will generally understand repair methodologies, material costs, and the practical realities of restoring a damaged property. An umpire whose experience is purely legal or administrative may lack the technical grounding to evaluate competing Xactimate estimates and may default to splitting the difference between two numbers — which systematically favors whichever side submitted the lower figure.

Be proactive, not reactive.The carrier’s appraiser will have a list of preferred umpires — people they have worked with before and who have produced favorable results for insurers. If you wait for the carrier’s appraiser to propose candidates first, you are already playing defense. Prepare your own list of qualified, genuinely neutral candidates and propose them before the other side sets the agenda. Propose candidates whose background aligns with the type of loss at issue — for a fire loss, an umpire with construction rebuilding experience; for a water loss, someone who understands moisture migration and remediation protocols.

Look beyond the usual suspects.Many appraisals involve the same small pool of umpires, some of whom develop reputations for consistently favoring one side. If a candidate has served as a carrier appraiser multiple times in recent years, that person’s “neutrality” as an umpire is questionable — even if they technically meet the statutory requirements. Push for candidates with no significant financial relationship with the insurer or its representatives.

The Panel Process

Once the panel is assembled (two appraisers and one umpire), the appraisers inspect the property (jointly or independently), prepare their respective estimates, and attempt to agree on the amount of loss. The statute contemplates that the appraisers will “appraise the loss, stating separately actual cash value and loss to each item.” If the appraisers agree, their agreement is the award. If they cannot agree, they “submit their differences, only, to the umpire.”

In practice, the two appraisers rarely agree on everything. The typical process involves each appraiser preparing a detailed estimate, the appraisers meeting to compare and discuss their positions, agreeing on items where they can, and submitting the remaining disputed items to the umpire. The umpire then reviews both positions, may inspect the property independently, and issues an award on the disputed items. An agreement by any two of the three — both appraisers, or one appraiser and the umpire — determines the amount.

IV. The Principals’ Role: Who Decides What Gets Appraised

Principals Define Scope

One of the most misunderstood aspects of appraisal is the distinction between the principals and the panel. The principals are the parties to the insurance contract: the insurer and the insured (or the insured’s representative — typically a public adjuster or attorney). The panel consists of the two appraisers and the umpire.

The principals define the scopeof the appraisal — what items will be submitted to the panel for determination. This is the Kacha principle in action: the principals decide what damage is in dispute as to amount (appropriate for appraisal) versus what damage is in dispute as to coverage (not appropriate for appraisal). The panel then determines the amount of loss for the items submitted to it.

Appraisers and Umpire Decide Amount Only

The panel’s authority is limited to determining the amount of loss for the items the principals have submitted. The panel does not decide coverage questions, does not interpret the policy, and does not make legal determinations. The appraisers evaluate the damage, prepare their estimates, and negotiate. The umpire resolves differences the appraisers cannot.

This division of authority is fundamental. The principals set the boundaries; the panel works within them. When this structure is respected, appraisal functions efficiently. When it breaks down — when the panel exceeds its authority or the principals fail to define the scope — the process can go sideways.

Scope vs. Value: The Practitioner’s Perspective

One of the most important tactical distinctions in appraisal practice is between scope (what items are damaged) and value (what those items cost to repair or replace). In a pure value dispute, both sides agree that the kitchen ceiling needs to be replaced; they disagree on the price. In a scope dispute, the carrier says only the kitchen ceiling is damaged while the policyholder says the hallway and bedroom ceilings are also affected. Most real-world appraisals involve both types of disagreement simultaneously.

Carriers frequently attempt to limit the appraisal to a value-onlyexercise — accepting only the scope the carrier already acknowledged and asking the panel merely to price those items. This approach, if successful, transforms the appraisal from an independent evaluation of the loss into a rubber stamp of the carrier’s scope determination with minor pricing adjustments. The result is predictably favorable to the carrier.

In California, the appraiser’s role is to independently evaluate the damage and determine the amount of loss — which necessarily includes assessing the extentof damage. An appraiser who merely reprices the carrier’s scope is not fulfilling the statutory role. Your appraiser should conduct an independent inspection, document every item of damage regardless of what the carrier acknowledged, and prepare an estimate that reflects the actualscope and value of the loss. The appraisal memorandum should explicitly address scope disputes, frame them as “amount” questions (the amount of damage to the hallway), and present the umpire with the evidence to evaluate them independently. For a consumer-level explanation of this distinction, see our Complete Guide to Insurance Appraisal.

Examples of Umpire Overreach

In practice, umpires sometimes exceed their authority. Common forms of umpire overreach include:

• Deciding causation: The umpire determines that certain damage was caused by a non-covered peril (e.g., wear and tear rather than storm damage) rather than limiting the analysis to the amount of the damage. Causation is a coverage question reserved for the principals or the courts, not the panel.
• Unilateral award format:The umpire issues an award in a format not agreed upon by the principals — for example, a lump-sum award without the itemization required by § 2071 (“stating separately actual cash value and loss to each item”). The statute requires itemization, and an umpire who issues a non-itemized award may be exceeding the panel’s authority.
• Ex parte contact:The umpire communicates privately with one appraiser or one party without including the other side. Ex parte contact between the umpire and one party is a serious procedural violation that can compromise the umpire’s neutrality and may be grounds for vacating the award.
• Refusing to meet or inspect:The umpire issues an award without meeting with the appraisers, without inspecting the property, or without reviewing the parties’ submissions. An umpire who refuses to hear material evidence may be violating CCP § 1286.2(a)(5).

V. Causation in California Appraisal: A Nuanced Area

The line between “amount” and “causation” is one of the most difficult issues in California appraisal law. Kachatells us that the panel determines amount, not coverage. But in many real-world claims, the two are intertwined — particularly in mixed-cause losses where damage results from both covered and non-covered perils.

Consider a roof that has both storm damage (covered) and wear and tear (not covered). How much of the damage was caused by the storm versus pre-existing deterioration? The insurer will argue this is a “causation” question outside the panel’s authority. The policyholder may argue it is an “amount” question — the panel is determining the amount of storm damage, which requires evaluating what was caused by the storm.

California courts have not drawn a perfectly clean line here. In general, the panel can evaluate the extentof damage caused by a covered peril — which necessarily involves some assessment of what was and was not caused by that peril — but the panel cannot make coverage determinationsabout whether a particular peril is covered in the first place. The distinction is subtle: the panel can say, “The storm damaged 50 squares of roofing and the cost to repair is X,” but the panel cannot say, “Wear and tear is not covered under this policy, therefore we exclude it.” The first is an amount determination; the second is a coverage determination.

Practical implications:The causation issue has significant strategic implications for the appraisal memorandum. If you frame the dispute as “how much storm damage is there,” you are asking the panel to evaluate the extent of covered damage — an amount question within the panel’s authority. If the insurer frames the dispute as “whether the damage was caused by storm or wear and tear,” it is arguing that the panel is being asked to make a coverage determination outside its authority. How the issue is framed can determine whether the panel addresses it at all.

V-B. Preparing a Compelling Appraisal Submission

The appraisal submission is your presentation to the umpire. In many appraisals, the umpire’s decision comes down to which side submitted a more persuasive, better- documented package. Preparation is not optional — it is the difference between a fair outcome and an inadequate one.

The Estimate: Line-Item Detail and Defensibility

Your estimate should be prepared in Xactimate whenever possible. Using the same estimating platform the insurance industry uses eliminates the carrier’s ability to dismiss your numbers as “not industry standard.” Every line item should be individually supported — with correct quantities, appropriate material grades, current pricing, and applicable overhead and profit. Do not leave gaps that the carrier’s appraiser can exploit.

Each disputed item should include enough detail that the umpire can independently evaluate it. If the carrier’s estimate excludes an item — for example, says the hallway does not need paint but your inspection shows smoke damage — your estimate should explain why the item is included, reference the supporting photograph or moisture reading, and provide the line-item cost. The umpire should not have to guess why a given item appears in your estimate.

Photographic and Physical Evidence

Photographs should be organized to correspond with your estimate. If your estimate includes 15 disputed line items, the umpire should be able to look at line item 7 (“replace smoke-damaged drywall, bedroom 2”), turn to the corresponding photograph section, and see clear images of the damage. Include:

• Wide-angle context shots showing the overall affected area
• Close-up detail shots showing the specific damage (char patterns, moisture staining, mold growth, structural displacement, etc.)
• Before-and-after photos when available
• Photos documenting concealed damage revealed during demolition or testing
• Photos from moisture meters, thermal cameras, or other diagnostic equipment with readings visible

Many appraisals are now conducted without a joint property inspection, particularly when repairs have already begun or when the parties are geographically dispersed. In those cases, your photographs are the evidence. Treat them accordingly.

Expert Reports and Supporting Documentation

For claims involving structural damage, hidden moisture, hazardous materials, or specialized building systems, expert reports can be decisive. An engineering report confirming structural compromise, an industrial hygiene report documenting mold contamination, or a mechanical engineer’s assessment of HVAC damage carries weight that a line item in an estimate alone does not. Include expert reports as attachments to your submission and reference them in your estimate notes.

Other supporting documentation may include: contractor bids for the disputed repairs, manufacturer specifications for materials or equipment that must be replaced, code requirements mandating specific repair methods, and correspondence from the claim file demonstrating the insurer’s prior positions on disputed items.

The Summary: Making the Umpire’s Job Easy

Provide a clear, concise summary that walks the umpire through the dispute. Identify the key areas of disagreement, explain the policyholder’s position on each, and direct the umpire to the specific evidence supporting your numbers. The umpire is typically reviewing two competing estimates, a stack of photographs, and possibly expert reports. If your submission is well-organized and easy to follow, the umpire can evaluate each issue on its merits. If it is a disorganized pile of documents, the umpire may fall back on heuristics — like splitting the difference — that systematically disadvantage the side with the higher (and often more accurate) figure.

VI. After the Award: Remedies, Confirmation, and Challenges

A. Can You Sue After Receiving an Appraisal Award?

Yes — in many circumstances. Receiving an appraisal award does not waive the policyholder’s right to pursue other claims against the insurer. The appraisal resolves the amount of loss, but it does not resolve:

• Bad faith claims: If the insurer acted in bad faith during the claims process — unreasonably delaying, lowballing, failing to investigate, or forcing the policyholder into appraisal to avoid paying what it owed — the policyholder can still sue for bad faith after the appraisal award is issued. The appraisal determines the amount; bad faith addresses the insurer’sconduct.
• Coverage disputes: If the insurer denied coverage for certain items and those items were excluded from the appraisal (as they should have been under Kacha), the policyholder can still litigate the coverage question. The appraisal award does not determine coverage.
• Breach of contract:If the insurer breaches the policy in ways beyond the amount of loss — for example, failing to pay the appraisal award promptly, violating policy conditions, or failing to advance Additional Living Expenses — the policyholder can sue for breach of contract.

B. Can You Set Aside an Appraisal Award?

Yes, but the grounds are narrow. As established in Lee v. California Capital, appraisal awards carry a strong presumption of finality. A party seeking to vacate an award must establish one of the grounds in CCP § 1286.2:

1. Corruption, fraud, or other undue means:The award was procured through dishonest conduct — for example, one party bribing the umpire or fabricating evidence.
2. Corruption or evident partiality of the umpire: The umpire was biased toward one party. Under Sharma, failure to make required disclosures under CCP § 1281.9 can establish evident partiality even without proof of actual bias.
3. Misconduct substantially prejudicing a party’s rights:The panel engaged in procedural irregularities that materially affected the outcome — for example, ex parte contact between the umpire and one appraiser, or refusing to allow one side to present its evidence.
4. The panel exceeded its powers:The panel decided issues beyond its authority — for example, making coverage determinations in violation of Kacha, or issuing an award that was not properly itemized as required by § 2071.
5. The panel’s refusal to hear material evidence:A party was denied the opportunity to present evidence that was relevant to the amount of loss. This can include the umpire refusing to inspect the property, refusing to review the appraiser’s submissions, or refusing to meet with the appraisers.

These grounds are intentionally narrow. Courts do not review appraisal awards for “errors” in the same way they review trial court decisions. The umpire’s valuation judgment — whether the loss is worth $100,000 or $200,000 — is not reviewable. What is reviewable is whether the process was fair and whether the panel stayed within its authority.

C. Enforcing and Collecting on the Award

A favorable appraisal award is only as valuable as the policyholder’s ability to collect on it. In theory, the insurer should pay the award amount (less applicable deductibles and prior payments) promptly upon receipt. In practice, the path from award to payment is not always smooth.

Confirming the award.The first step in enforcement is petitioning the court to confirm the appraisal award under CCP § 1285. Once confirmed, the award becomes a court judgment — enforceable through all the collection mechanisms available for any civil judgment, including writs of execution, bank levies, and lien filings. File the confirmation petition promptly after receiving the award; there is no strategic reason to delay.

Carrier resistance after the award.Some insurers treat the appraisal award as the beginning of a new negotiation rather than a binding determination. They may request “additional documentation” before processing payment, raise new objections that were never raised during the appraisal, or simply fail to issue a check within any reasonable timeframe. These tactics are designed to extract further concessions from a policyholder who is tired of fighting and may accept less than the full award just to get paid.

Do not renegotiate a binding award.The appraisal award determined the amount of loss. Unless the insurer has a legitimate basis to challenge the award under CCP § 1286.2 (and has filed a timely petition to vacate), the award amount is what the insurer owes. Engaging in post-award “negotiation” validates the carrier’s delay tactic and signals that the award figure is negotiable when it is not.

Delay as bad faith evidence.An insurer’s unreasonable delay in paying a binding appraisal award is not merely frustrating — it is potential evidence of bad faith. The award has eliminated any genuine dispute about the amount of loss. Once that amount is determined, the insurer’s continued failure to pay has no reasonable basis — and under California’s Genuine Dispute doctrine, the absence of a reasonable basis for withholding benefits is precisely what creates bad faith liability. Document the delay meticulously: when the award was issued, when and how it was served on the insurer, what payment demands were made, and every communication (or lack thereof) from the insurer following the award.

VII. When Appraisal Goes Off the Rails: Real-World Problems and Court Intervention

Appraisal does not always go smoothly. The statutory framework assumes good faith participation by all parties, but in practice, problems arise regularly. The following are the most common issues and how to address them.

A. Appraiser Refuses to Provide a Position

The appraisal process requires each appraiser to “appraise the loss, stating separately actual cash value and loss to each item.” This means each appraiser must prepare and present a position — a detailed estimate reflecting their assessment of the loss. Occasionally, an appraiser (usually the insurer’s appraiser) refuses to provide a written position, claiming they will “wait to see what the other side submits” or “evaluate the umpire’s position.”

This is a violation of the appraisal process. The statute requires each appraiser to appraise the loss and state their position. An appraiser who refuses to do so is not fulfilling the role. If the insurer’s appraiser refuses to provide a position, document the refusal in writing and consider raising the issue with the umpire or, if necessary, seeking court intervention. An appraisal conducted without both appraisers fulfilling their statutory obligations may produce an award that is vulnerable to challenge.

B. Umpire Misconduct or Incapacity

Umpire misconduct takes many forms: bias toward one party, ex parte communications, refusal to inspect the property, failure to review submissions, issuing an award without meeting with the appraisers, or simply failing to act (the umpire “goes dark” and stops responding). Umpire incapacity — illness, death, or other inability to serve — also stalls the process.

When the umpire’s conduct is problematic but the appraisal is still ongoing, the first step is to raise the issue in writing — to the umpire directly, with a copy to the opposing appraiser and the insurer. Document the specific conduct at issue: what the umpire did or failed to do, when it occurred, and why it is improper. If the misconduct continues, or if the umpire is incapacitated, either party can petition the court to remove and replace the umpire. Under the arbitration framework, the court has authority to ensure the process is conducted fairly.

C. Insurer Interference with the Appraisal Process

Some insurers participate in appraisal in good faith. Others use the process strategically — to delay payment, to wear down the policyholder, or to blur the lines between the insurer’s role as a principal and the appraiser’s role as a panel member. Common forms of insurer interference include:

• Blurring the lines between principal and appraiser:The insurer directs its appraiser on specific positions to take, prevents the appraiser from negotiating in good faith, or treats the appraiser as an employee rather than an independent panel member. While the appraiser is an advocate for the insurer’s position (per Lambert), the appraiser must still exercise independent judgment as a member of the panel.
• Withholding information:The insurer refuses to share its claim file, investigation reports, or other documents that are relevant to the appraisal. The policyholder’s appraiser may need access to the insurer’s inspection reports, engineering reports, or prior estimates to evaluate the dispute.
• Delaying the process:The insurer takes the maximum time to select an appraiser, then delays umpire selection, then delays scheduling inspections — dragging the process out for months or years while the policyholder waits for payment.
• Bad faith through appraisal: In extreme cases, the insurer invokes appraisal (or forces the policyholder to invoke it) as a delay tactic, knowing that the process will take months and that the policyholder may be financially unable to wait. Using appraisal as a tool to avoid paying a claim can itself constitute bad faith.

D. Carrier Appraiser Tactics to Watch For

The insurer’s appraiser is an advocate for the insurer’s position — that is established by Lambert v. Carneghi. But advocacy is one thing; the following tactics cross the line into gamesmanship that can distort the process and produce an unfair result. Recognizing them is the first step to countering them.

• Deliberate delay on umpire selection.The carrier’s appraiser rejects every proposed umpire, proposes only candidates with known carrier affiliations, or simply fails to respond to communications about umpire selection. The goal is to drag the process out — keeping money in the carrier’s pocket while the policyholder waits. Counter this by documenting the obstruction and moving to court appointment promptly once the 15-day window expires.
• Lowball anchoring.The carrier’s appraiser submits an artificially low estimate — sometimes lower than the insurer’s own original payment — knowing that some umpires default to “splitting the difference” between the two figures. If your estimate is $200,000 and the carrier’s appraiser submits $50,000, a lazy split-the-difference approach yields $125,000 — well below the actual loss. The counter is a detailed, well-documented estimate that stands on its own merits, making it clear to the umpire that each line item is independently supported.
• Scope exclusion.The carrier’s appraiser attempts to exclude items from the appraisal on the theory that they are “coverage issues” rather than “amount issues.” This is a way of shrinking the pie before the umpire even sees it. While genuine coverage disputes are outside the panel’s authority per Kacha, the extent of physical damage is an amount question that the panel can and should evaluate. Push back on any attempt to remove legitimately damaged items from the appraisal scope.
• Xactimate pricing manipulation. The carrier’s appraiser uses Xactimate pricing but manipulates it — by selecting the lowest possible material grades, stripping out overhead and profit, using outdated price lists, removing legitimate line items, or applying unit-cost adjustments that reduce the per-item price below market rates. Because Xactimate carries an air of objectivity, an umpire unfamiliar with the software may accept these manipulated figures at face value. Your appraiser needs to identify and document every deviation from fair pricing in the carrier’s estimate.
• Refusing to provide a written position.Some carrier appraisers avoid committing to a written estimate, preferring to “wait and see” what the policyholder’s appraiser submits before taking a position. This violates the statutory requirement that each appraiser independently appraise the loss. Insist on simultaneous exchange of estimates, or document the refusal as a procedural violation that may support a future challenge to the award.

E. Death or Incapacity of a Party Appraiser

If a party appraiser dies or becomes incapacitated during the appraisal, the process stalls. The statute does not explicitly address this scenario, but under general arbitration principles, the party whose appraiser has become incapacitated has the right to select a replacement. The replacement appraiser steps into the role and the process continues. If the parties cannot agree on how to proceed — for example, if the opposing party argues that the replacement appraiser must accept the positions already taken by the original appraiser — the court can intervene to resolve the dispute.

The replacement appraiser is not bound by the prior appraiser’s positions. The new appraiser has the same rights and obligations as the original — they must independently appraise the loss and state their position. Any work product from the prior appraiser may be informative but is not binding on the replacement.

F. Seeking Court Intervention

Courts generally prefer not to intervene in appraisal proceedings until the process is complete and an award has been issued. The preferred approach is to allow the process to run its course and then challenge the award if necessary under CCP § 1286.2.

However, there are circumstances where courts will intervene before an award is issued:

• Umpire appointment:When the appraisers cannot agree on an umpire, the court appoints one under § 2071.
• Umpire removal: When the umpire has demonstrated bias, failed to make required disclosures, or is incapacitated, the court can remove and replace the umpire.
• Scope disputes:When the parties disagree about whether a particular issue falls within the panel’s authority (amount vs. coverage), the court can determine the scope of the appraisal before the panel proceeds.
• Refusal to participate:When one party refuses to participate in the appraisal process at all — for example, refusing to select an appraiser or refusing to comply with a valid appraisal demand — the court can compel participation.
• Fundamental procedural breakdown:When the process has broken down so completely that continuing would be futile — for example, when the umpire has engaged in conduct so egregious that any resulting award would be unenforceable — the court may intervene to restart or restructure the process.

The Key Principle: Everyone Must Stay in Their Lane

If there is one principle that runs through every section of this guide, it is this: everyone must stay in their lane.

• The principals (insurer and policyholder or their representative) define the scope. They determine what items are in dispute as to amount and submit those items to the panel. They do not appraise the loss themselves.
• The party appraisers are advocates. They evaluate the loss, prepare estimates, and negotiate with each other. They do not decide coverage. They do not act as neutrals.
• The umpire is the neutral tiebreaker. The umpire resolves the differences the appraisers cannot resolve. The umpire does not advocate for either side, does not decide coverage, does not interpret the policy, and does not act as a judge.
• The courtsresolve coverage disputes, enforce or vacate awards, and intervene when the process breaks down. They do not re-appraise the loss or second-guess the panel’s valuation judgment.

When everyone stays in their lane, appraisal works as intended: a fair, efficient, binding process for resolving the dollar amount of an insurance claim without the cost and delay of litigation. When roles are confused — when the umpire acts as an advocate, when the insurer treats its appraiser as an employee, when the panel makes coverage determinations, or when a party treats appraisal as an obstacle rather than a resolution mechanism — the process breaks down, and the resulting award may be neither fair nor enforceable.
