Arbitration is a private process in which a neutral third party hears both sides and issues a decision. It substitutes for a court proceeding, and in insurance it most commonly appears in uninsured and underinsured motorist disputes, though some policies apply it more broadly.
How it differs from the two things it gets confused with
| Decides | Who decides | Binding | |
|---|---|---|---|
| Appraisal | The amount of a loss only | Two appraisers and an umpire | Usually, on the amount |
| Arbitration | Liability and damages | One or three arbitrators | Depends on the clause |
| Court | Everything | Judge or jury | Yes, subject to appeal |
The key distinction from appraisal: appraisal answers how much. Arbitration can answer who was at fault and how much, which is a broader question.
Binding and non-binding
This is the single most important thing to establish before agreeing to anything.
Binding arbitration produces a decision both sides must accept. Grounds for challenging an award in court are narrow — typically limited to matters such as fraud, corruption, or an arbitrator exceeding their authority. Being wrong about the facts is generally not enough.
Non-binding arbitration produces a decision either side may reject, after which the matter proceeds to court. Some policies make it binding only below a stated amount.
Read your clause before the process starts, not after. Ask specifically: is it binding, is it binding only up to a certain figure, and can either party reject the award. Those three answers determine what you are agreeing to.
What the clause typically sets
- How arbitrators are chosen. Commonly each side names one and those two select a third; sometimes a single neutral arbitrator is used.
- Who pays. Usually each side pays its own arbitrator and they share the neutral's fee, though this varies.
- What rules apply. Some clauses adopt the rules of an arbitration organisation; others leave the procedure to the arbitrators.
- Where it takes place. Frequently the county where you live.
- Whether discovery is available. Arbitration usually involves less document exchange and fewer depositions than litigation, which cuts cost and time but also limits what you can obtain from the other side.
The sequence
- A demand is served by whichever party invokes the clause.
- Arbitrators are selected within the period the clause sets.
- A limited exchange of information takes place — medical records, wage documentation, the police report, expert reports.
- Briefs are submitted, setting out each side's position.
- A hearing is held, usually far shorter and less formal than a trial. Witnesses may testify; medical evidence is often presented in writing.
- The award issues, typically within a stated period afterwards.
Why insurers include these clauses
Arbitration is generally faster and less expensive than litigation for both sides. It is also private, and it does not produce the kind of public record a court judgment does.
Whether it favours one side is contested, and the honest answer is that it depends on the clause, the forum, and the case. What is not contested is that it narrows discovery and narrows the grounds for challenging the outcome, and both of those matter more to the party with less information.
State variation
States differ on whether an insurer may compel arbitration of an insurance claim, whether such clauses are enforceable in personal lines policies at all, and what grounds exist for vacating an award. A few states restrict mandatory arbitration in specific types of insurance.
Your Department of Insurance can tell you how these clauses are treated where you live, and it is worth asking before assuming the clause in your policy is enforceable as written.
What to do if you receive a demand
- Find the clause and read it in full.
- Establish whether it is binding and up to what amount.
- Note every deadline in the clause, particularly for naming an arbitrator. Missing it can mean one is appointed for you.
- Assess the amount at stake against the cost of participating.
- Consider legal advice where the amount is significant. Arbitration is an adversarial proceeding, and the insurer will be represented.
What we are not saying
We are not telling you whether to agree to arbitration, whether the outcome is likely to favour you, or whether a clause in your policy is enforceable in your state.
What we are saying is that arbitration decides more than appraisal does, that whether it binds you is the first question to answer, and that the grounds for challenging a binding award afterwards are extremely narrow.
Where to verify this yourself
- Your policy — the arbitration clause, including whether it binds and how arbitrators are selected.
- Your state Department of Insurance — how arbitration clauses are treated in your state.
- An attorney licensed in your state — whether to participate and how, where the amount is significant.
Where arbitration clauses actually appear
Most policyholders encounter arbitration in one specific place: uninsured and underinsured motorist claims. The reason is structural.
In a UM or UIM claim you are claiming against your own insurer for damages caused by someone else. That puts your insurer in the position of evaluating — and potentially disputing — the value of your injuries, which is the kind of dispute that would otherwise go to court. Arbitration clauses in these coverages exist to resolve it privately.
Beyond UM and UIM, arbitration appears in some homeowners policies, in many commercial policies, and occasionally in health plan documents. Whether such a clause is enforceable against a consumer varies by state, and a few states restrict mandatory arbitration in specific lines.
The three processes, side by side
| Appraisal | Arbitration | Litigation | |
|---|---|---|---|
| Decides fault | No | Usually yes | Yes |
| Decides amount | Yes | Yes | Yes |
| Decides coverage | No | Sometimes | Yes |
| Discovery available | Minimal | Limited | Full |
| Decision-maker | Appraisers and umpire | One or three arbitrators | Judge or jury |
| Public record | No | Usually no | Yes |
| Appeal grounds | Very narrow | Very narrow if binding | Ordinary appeal rights |
| Typical duration | Weeks to months | Months | Often years |
The rows on discovery and appeal grounds are the ones worth dwelling on. Arbitration trades procedural rights for speed and cost, and that trade affects the party with less information more than the party with more.
Reading your clause: the six questions
Before anything else, establish
- Is it binding? And if so, is it binding at all amounts or only below a threshold?
- Who may demand it? Either party, or only the insurer?
- How many arbitrators? One neutral, or one each plus a third?
- What is the deadline for naming yours after a demand is served?
- Who pays what? Own arbitrator plus a share of the neutral is typical, but not universal.
- What rules govern? An arbitration organisation's rules, or whatever the arbitrators decide?
Write the answers down before responding to any demand. The deadline for naming an arbitrator is the one that catches people, because missing it can result in one being appointed for you.
Preparing a UM or UIM arbitration
These turn on liability and on damages, and the material is the same as would be prepared for a trial — just presented more compactly.
-
Liability
Establishing fault
Police report, scene photographs, witness statements, any reconstruction. In comparative negligence states, the apportionment itself is frequently the contested question.
-
Medical
Causation and extent
Complete records from every provider, imaging, and a narrative report from the treating physician addressing causation and prognosis. Records alone rarely make the argument; a narrative report does.
-
Economic
Wage loss and future costs
Employment records, tax documents, an employer letter confirming time lost, and where relevant a life care plan for future treatment.
-
Non-economic
Effect on daily life
Where your state allows recovery for it. Contemporaneous evidence — a symptom diary kept during recovery, statements from people who observed the change — is more persuasive than a later account.
-
Coverage
The policy mechanics
Your UIM limits, whether your state uses a reduction, excess or trigger approach, and confirmation that you complied with any consent-to-settle requirement.
The consent-to-settle trap, again
It belongs here as well as in the UM guide, because it surfaces at exactly this point.
Most policies require you to notify your own insurer and obtain consent before accepting a settlement from the at-fault driver. Accepting a quick offer and signing a release without doing so can extinguish your insurer's subrogation rights — and under many policies that defeats the UIM claim entirely.
By the time an arbitration demand is served, this has usually already happened or not. If you are earlier in the process, notify in writing before signing anything.
What the hearing is like
Less formal than a trial and considerably shorter. Frequently a single day or less. Held in a conference room rather than a courtroom, with no jury.
Medical evidence is often presented in writing rather than through live testimony, which is one of the main reasons arbitration is faster and cheaper. Witnesses may testify, and you will usually testify yourself about the accident and its effects.
The arbitrators will have read the briefs and the exhibits beforehand. The hearing is where the gaps get probed, not where the case is presented from scratch.
Whether to be represented
We do not give legal advice and cannot tell you what to do. What is worth stating plainly is the asymmetry: the insurer will be represented by someone who does this regularly, the process is adversarial, and if the clause is binding the outcome is very difficult to disturb.
For a modest claim, people do represent themselves. For a significant injury claim, the combination of a binding outcome, narrow appeal grounds, and limited discovery is the reason most people in that position obtain representation. Many attorneys in this area work on contingency, and state bar referral services can help you find one.
Challenging an award
Grounds are deliberately narrow — typically limited to matters such as fraud, corruption, evident partiality of an arbitrator, or an arbitrator exceeding their authority. Reaching the wrong conclusion on the facts is generally not enough, and neither is a misunderstanding of the law in most jurisdictions.
There are usually strict time limits for applying to vacate an award, measured from when it was delivered. If you intend to challenge one, that deadline matters as much as any other in this guide.
What we are not saying
We are not telling you whether to agree to arbitration, whether your clause is enforceable in your state, or how a particular arbitrator is likely to decide.
What we are saying is that arbitration decides more than appraisal does, that whether it binds you is the first thing to establish, that the deadline for naming your arbitrator is short, and that a binding award is close to final.
A checklist for the first week after a demand
Do these in order
- Find the arbitration clause in your policy and read it completely
- Establish whether it binds, and at what amounts
- Diary the deadline for naming your arbitrator, working backwards from the date the demand was received
- Confirm how costs are allocated, so the financial commitment is known
- Check whether your state restricts these clauses in this type of policy
- Assess the amount genuinely at stake against the cost of participating
- Decide on representation before the deadline, not after
- Gather your file — policy, correspondence, medical records, log — into one place
The sequencing matters. Deciding about representation after naming an arbitrator narrows the options, because an attorney brought in later inherits choices already made. If the amount is significant enough that you would want advice at any stage, the useful moment is now.
One last practical note
Ask whoever serves the demand, in writing, to confirm which set of procedural rules will govern and where the hearing will be held. Both are usually specified in the clause, but confirming them early avoids a dispute about process on top of the dispute about substance.
This is general education, not advice. Insurance law and claim rules vary by state and change over time. Nothing here is legal, financial, or insurance advice for your situation, and reading it does not create any professional relationship. For your specific case, consult a licensed professional in your state or contact your state Department of Insurance.
