Insurance arbitration: how policyholder and insurer claims get decided

The short version

• Insurance arbitration is not one process. Six kinds run in parallel, each with its own forum, rulebook and payer.
• One whole kind is insurer against insurer. Carriers recover from each other through Arbitration Forums, Inc. (AF) on paper, under informal and confidential rules, up to $100,000 a claim (AF Rules 1-3 and 3-6, effective 21 October 2024). The policyholder is not a party.
• A policyholder can be steered into arbitration or appraisal by the policy wording. Uninsured-motorist disputes are arbitrated under a prescribed endorsement, which in New York the American Arbitration Association (AAA) administers; no-fault gives the claimant the option to arbitrate first-party benefits (New York Insurance Law section 5106(b)).
• Appraisal is not arbitration. It fixes only the amount of loss, not whether the claim is covered (New York Insurance Law section 3404(e)).
• Whether an insurer can force a policyholder into binding arbitration is a state question. The McCarran-Ferguson Act lets a state insurance law reverse-preempt a federal Act that does not specifically relate to insurance, such as the Federal Arbitration Act (15 U.S.C. 1012(b)), and in some states the courts read an insurance statute to bar the clause; Washington, for example, reads RCW 48.18.200 that way, a reading that comes from case law, not the statute’s own words.^1,4,6,9,10

What is insurance arbitration, and how is it different from going to court?

Insurance arbitration is a private process in which a neutral arbitrator or panel, not a judge, decides an insurance dispute and issues an award. It covers everything from a routine subrogation file between two carriers to a coverage fight on a policy worth millions. Subrogation means one insurer paying its own policyholder and then standing in that policyholder’s shoes to recover from whoever was at fault. A first-party claim is one you bring against your own insurer under your own policy.¹

Insurance arbitration is one answer to the wider question of insurance dispute resolution, and it sits next to three neighbours that are easy to confuse. Appraisal decides only the amount of loss, not whether the claim is covered (section 3404(e)). An ombudsman is a free complaints route, not an arbitrator, and its decision binds the insurer only if the consumer accepts it (for example the UK scheme, FSMA 2000 section 228(5)); see insurance ombudsman schemes. A court enforces or sets aside an award, and it appoints the appraisal umpire when the two appraisers cannot agree (section 3404(e)).^6,14

Arbitration is also not mediation. A mediator helps the parties reach their own settlement but decides nothing. Litigation is the public court route, where a judge decides on the record; arbitration is the private route, where a chosen neutral decides and the result is an award.

There is no single insurance arbitration code the way there is for securities or futures. The AAA publishes sample arbitration clauses for insurance and reinsurance contracts and a ClauseBuilder tool to draft them, and a sample clause sends the dispute to the AAA’s Commercial Arbitration Rules rather than a bespoke insurance rulebook. In every kind the decision stays with a named arbitrator, which is the same line the AI guidance draws; see AI in arbitration. The neighbouring map for banks, brokers and investment firms is financial markets arbitration.¹⁵

What are the main kinds of insurance arbitration?

There are six kinds, grouped by who is fighting whom, and how insurance arbitration works depends on which one you are in. The table sets out who runs each, who pays and whether the award binds. The paragraphs below hand the detail to the four spokes.^1,15

Policyholder against insurer under a policy clause is the kind people mean by insurance claim arbitration. These are first-party claims on property, disability or life policies, run under the AAA’s Commercial Arbitration Rules or whatever rules the clause names. Whether the clause can be enforced against you is the live question; see are insurance arbitration clauses enforceable?.¹⁵

Uninsured and underinsured motorist arbitration (UM, UIM, or supplementary cover, SUM) is between you and your own insurer, over liability and damages when the at-fault driver has no cover or not enough. In New York the uninsured-motorist provision is mandatory (section 3420(f)(1)), and optional supplementary UM/SUM cover runs up to $250,000 for one person and $500,000 for an accident (section 3420(f)(2)). The right to arbitrate sits in the endorsement the Superintendent prescribes, which the AAA administers through its New York Insurance ADR Center.^3,16

No-fault, or personal injury protection (PIP), is the claimant’s option, not a clause forced on them. Every New York insurer must offer arbitration of a first-party benefits dispute under simplified procedures (section 5106(b)); Regulation 68 provides for an organisation designated by the Superintendent (11 NYCRR 65-4.2), and the AAA is that organisation (AAA New York Insurance ADR Center), with an award reviewed only by a master arbitrator, a senior arbitrator who hears the appeal (65-4.10).^4,5,17

Inter-company arbitration is carrier against carrier over subrogation, and it is covered next. Reinsurance is insurer against reinsurer, covered below and in how reinsurance arbitration works. Commercial coverage arbitration is a business against its insurer on a large or specialty policy, run under general commercial rules; the drafting choices on scope, panel and consolidation are handed to the same spoke.⁸

What a hearing looks like changes with the kind. Inter-company subrogation is decided on the papers, under informal and confidential procedure with no formal rules of evidence (AF Rules 2-13 and 3-6). No-fault runs on a simplified track (section 5106(b)). A reinsurance dispute is heard by a party-appointed panel of three under ARIAS (US) rules (ARIAS (US) Rules 6.1).^1,4,8

Why do insurers arbitrate against each other?

Because when two insured parties collide, each insurer pays its own policyholder first and then recovers from the other. Rather than sue each time, carriers agree in advance to arbitrate these subrogation claims through Arbitration Forums, Inc. It is the insurance arbitration most people never see, because no policyholder is a party.¹

AF administers the inter-company agreements, and only insurers and self-insureds, or large-retention commercial insureds, are members. An individual policyholder cannot file. Arbitration is compulsory between members up to $100,000 total company-paid damages in the Automobile, Medical Payment, Property and Uninsured Motorists forums, and up to $250,000 in the Special Arbitration forum (Rule 1-3, effective 21 October 2024).^1,2

One arbitrator hears a case, and a three-person panel can be requested at $15,000 and above (Rule 3-3). The hearing is informal and confidential, and formal rules of evidence do not apply (Rules 2-13 and 3-6). The recovering company starts the case by filing online and pays the filing fee (Rule 6-1); the responding company that files a counterclaim also pays. The losing company pays the award within 30 calendar days of the decision (Rule 5-1).¹

Appeals are limited. A party may appeal only in the Property forum at $10,000 and above and in the Special forum at $100,000 and above, and the appeal decision is final and binding with no further review (Rule 2-12). New York makes inter-company loss-transfer arbitration, one insurer recovering its no-fault payouts from another, mandatory by statute and administers it through an organisation the Superintendent designates, whose jurisdiction takes priority over the voluntary inter-company agreements (section 5105; 11 NYCRR 65-4.11).^1,5

How does car-insurance arbitration work?

There is no single car-insurance arbitration. A motor dispute can land in three different places depending on the coverage. The thing being decided, and the person on the other side, change with it.¹

• Who hit whom, between insurers: inter-company subrogation through the AF Automobile forum. You are not a party; your insurer and the other driver’s insurer are (AF Rules).
• Your own injury when the other driver was uninsured or underinsured: UM/SUM arbitration under the prescribed endorsement, you against your own insurer, administered by the AAA (New York example: section 3420(f)).
• Your own medical and first-party benefits in a no-fault state: the claimant’s option to arbitrate under simplified procedures, with the AAA designated and a master-arbitrator appeal (section 5106(b); 11 NYCRR 65-4.2 and 65-4.10).^1,3,4,5,16

One caveat, because some law-firm pages blur it. Court-annexed compulsory arbitration of small civil suits is a court programme set by state court rules, and it is not insurance-policy arbitration. Keep the two apart: one is run by the court, the other by the policy and the forum its rules name. The wider New York seat mechanics are in arbitration in New York.

Can my insurer force me into arbitration?

Sometimes, and it depends on the coverage and the state. The policyholder is never forced into inter-company arbitration, because that is between carriers. Where a policy clause does apply to you, whether an insurer can make it stick is where the fight is.³

• Can be required of you: UM/SUM arbitration, through the prescribed endorsement the AAA administers (section 3420(f)).
• Offered to you, your choice: no-fault is the claimant’s option, not a forced clause (section 5106(b)).
• The enforceability question: the Federal Arbitration Act normally makes a written arbitration agreement binding, but a state insurance law can override it.^3,4

The override runs through the McCarran-Ferguson Act. It lets a state insurance law override (‘reverse preempt’) a federal Act that does not specifically relate to the business of insurance (15 U.S.C. 1012(b)), so a state anti-arbitration insurance statute can void a policy’s arbitration clause. Washington’s code voids any policy condition depriving the courts of this state of the jurisdiction of action against the insurer (RCW 48.18.200(1)(b)); the effect on a forced arbitration clause comes through how the courts have read that statute, not from its own words.^9,10

So a mandatory or forced arbitration clause in an insurance policy is not enforceable everywhere. The full state-by-state picture, the split among the federal courts over foreign and reinsurance clauses under the New York Convention, and the UK consumer carve-out are in are insurance arbitration clauses enforceable?. A free consumer complaints route, where you do not want arbitration at all, is in insurance ombudsman schemes.⁹

Arbitration, appraisal, an ombudsman or a court: which decides my claim?

They decide different things. Appraisal fixes only the amount of loss. Arbitration can decide the whole dispute. An ombudsman is a free complaints route. A court enforces or overturns the result. The table lines them up, and the paragraphs below fill in appraisal, the one most often mistaken for arbitration.^6,12,13

Appraisal is the route for a homeowners or property claim where the insurer agrees it owes something but the two sides cannot agree on how much. An appraiser is a valuer each side picks to put a number on the loss; an umpire is the neutral who breaks a tie between them, and on either side’s request a judge of a court appoints that umpire if the two appraisers deadlock (section 3404(e)). Appraisal fixes only the amount of loss, never whether the claim is covered.⁶

Massachusetts calls the same thing a reference of the amount of a loss to three referees (M.G.L. ch. 175 section 99). The full mechanics, the cost split and how appraisal differs from arbitration on amount of loss are in the insurance appraisal process. The ombudsman route, free to the consumer and binding on the insurer only if the consumer accepts, is in insurance ombudsman schemes.⁷

The court sits behind all of these. The Federal Arbitration Act makes a written arbitration agreement ‘valid, irrevocable, and enforceable’ (9 U.S.C. 2); a court confirms an award (9 U.S.C. 9) or may vacate it only on the Act’s narrow grounds, such as the arbitrators having ‘exceeded their powers’ (9 U.S.C. 10(a)(4)). It also appoints the appraisal umpire when the appraisers deadlock (section 3404(e)). How the narrow grounds work is handed to the clauses spoke.^6,11,12,13

How is reinsurance arbitration different?

Reinsurance is insurance bought by insurers, so a reinsurance dispute is between an insurer (the cedent, the company passing on the risk) and its reinsurer. It comes as treaty cover, which takes whole classes of business, or facultative cover, which is placed risk by risk. This is a long-established, specialised kind of insurance arbitration, run by the industry itself under ARIAS (US) rules rather than by a consumer forum.⁸

The panel is three disinterested arbitrators, one appointed by each side, with the two party-appointed arbitrators choosing a neutral umpire (ARIAS (US) Rules 6.1), and the majority’s award is final and binding (15.2). How the panel is selected, the umpire procedure, the honourable-engagement clause, confidentiality, pre-hearing security and enforcement are in how reinsurance arbitration works.⁸

What would make insurance disputes fairer and faster?

In our view, insurance disputes are already built for consistency, and that is where their fairness and speed should come from. Every kind we have mapped runs on a written rulebook: a policy wording, Arbitration Forums’ rules, Regulation 68, a reinsurance treaty’s clause. Most are small and alike, and there are a great many of them. Inter-company arbitration decides routine subrogation on paper, under informal and confidential procedure, up to a fixed dollar limit (AF Rules 1-3 and 3-6). No-fault gives the claimant a simplified track with a master-arbitrator appeal (New York Insurance Law section 5106(b); 11 NYCRR 65-4.10). What keeps that fair is sameness: each file decided the same way under the same rule, by a named person who signs the award, on a record each side can check and a court can confirm or set aside. Appraisal shows the limit: it fixes only the amount of loss, and a judge still appoints the umpire when the two sides cannot agree (section 3404(e)). The same logic places any AI on the reading and the drafting, never the decision, which the rules leave with that named person. That is also why a state can bar a forced clause (15 U.S.C. 1012): fairness here is a property of the rule, not the forum.^1,4,5,6,9
