Auto Insurance Claim Statute of Limitations: First-Party and Tort Deadlines by State

Three types of deadlines, not the same thing

Everything on this page is about the statute of limitations, which is the deadline for filing suit. Before getting there, two other deadlines from the policy itself usually arrive first, and conflating them with the SOL is the most common cause of a claim being lost months before anyone talks about suit.

• Policy notice conditions. Standard auto policies require the insured to report the loss to the carrier promptly, cooperate in the investigation, and (on carrier request) submit a sworn proof of loss within a defined window. These are conditions of coverage, not suit deadlines. A late or missing notice can defeat the claim even if the state SOL is years away, depending on state law on prejudice.¹
• First-party contractual limitation (suit against your own carrier). The ISO Personal Auto Policy Legal Action Against Us clause typically requires suit on a first-party claim within a defined period (often shorter than the state’s general written-contract SOL). This is the carrier’s own filing deadline on a contract claim and runs independently of either the notice conditions above or the tort SOL below. State law varies on whether a policy’s shortened period is enforceable.¹
• Third-party tort statute of limitations (suit against the at-fault driver). A separate state statute on personal-injury and property-damage torts controls when you can sue the at-fault driver (and reach their liability carrier). It has nothing to do with your own policy; it is set by the state civil code.

These three deadlines are legally distinct, run on different clocks, and are measured from different events. Missing any one of them can end the matching path even if the other two are still alive. The sections below focus on the two statutes of limitations (first-party contract and third-party tort), with policy notice conditions treated under "How the policy itself can shorten the clock."

The two SOL clocks: contract SOL vs tort SOL

Insurance consumers often think of a car-accident claim as a single event with a single deadline. In practice it is two legally separate claims that run on two separate clocks, each governed by a different state statute.

First-party contract SOL (against your own carrier)

A first-party claim is a claim you file against your own insurer under your own policy. The common first-party coverages are collision, comprehensive, uninsured and underinsured motorist (UM/UIM), personal injury protection (PIP), and medical payments (medpay). Because the carrier’s obligation to pay comes from the written insurance contract, the applicable SOL is the state’s statute of limitations on written contracts, which in most states runs 3 to 10 years.

The clock on a first-party claim typically does not start on the accident date. It starts when the carrier breaches the contract. In the ordinary case that means the date of final denial, the date of the last partial payment, or the date the carrier refuses to arbitrate when the policy requires it. Some policies state that the clock runs from the date of the loss itself; whether that contractual language is enforceable depends on state law, and the question is one of the most heavily litigated areas of first-party coverage.¹³

For context on the carrier conduct that often constitutes the breach triggering this clock, see what to do when a claim is denied and how to appeal and (for carrier conduct that may itself be actionable) bad-faith claims against your own insurer.

Third-party tort SOL (against the at-fault driver)

A third-party claim is a tort claim against the at-fault driver. Practically, you recover through that driver’s liability carrier, but the underlying legal claim is negligence against the driver, not a contract claim against the liability carrier (you are not a party to that contract). The applicable SOL is the state’s statute of limitations on personal injury torts (for bodily injury) or on property damage (for vehicle damage), which in most states runs 1 to 6 years.

The clock on a tort claim almost always starts on the accident date. A narrow set of latent-injury cases triggers the discovery rule in some states, which starts the clock when the injury was discovered or reasonably should have been. Minors and incapacitated plaintiffs are tolled in many states until the age of majority or until capacity is restored, but the exact mechanic varies, and relying on a tolling assumption without checking the statute is unsafe.³

The hybrid case: UIM

UIM claims sit awkwardly between contract and tort. They are contract claims (you are suing your own carrier), but the carrier’s liability is derivative of the tortfeasor’s negligence. A number of states apply a shorter special SOL to UIM arbitration or suits for this reason, and most UIM endorsements impose their own policy-defined demand window that is separate from the state SOL. For the UIM-specific procedural layer, see the UIM claim process guide.

State matrix: typical contract and tort SOLs

The table below is a reference starting point, not a substitute for the current statute. State SOLs change through legislation and appellate decision, policy forms can shorten the first-party window, and tolling rules change by state and by claim type. These are current typical periods; always verify your state’s current statute. Policy contracts can shorten the first-party period.

For states not listed above, assume neither extreme and verify at the state DOI consumer page or at the state statute. The numbers above are drawn from general practitioner references and are current as of the review date on this page; a change in state law after that date is not reflected here. Verify before relying.⁴⁵

When each clock starts

The length of an SOL is only half the question. The other half is when the clock begins to run. The two clocks typically start at different events.

First-party contract trigger

• Breach, not accident. The ordinary rule is that a contract SOL starts on breach. For a first-party auto claim, breach is typically the carrier’s final denial, the date of a last partial payment that the insured rejects, or the carrier’s refusal to arbitrate when the policy requires arbitration.
• Policy may displace the default. Some policies state that the clock runs from the date of loss rather than from breach. Some states enforce that language; some do not. Read your actual Part F conditions, not a specimen policy from a different carrier or state.¹
• Ongoing negotiation generally does not toll. Many insureds assume that an open file at the carrier keeps the clock from running. In most states, it does not. Only formal tolling (minority, incapacity, specific statutory carve-outs) stops the clock, and relying on an informal assumption that the clock is paused is a common way claims are lost.

Third-party tort trigger

• Accident date is the default. The tort clock almost always starts on the date of the accident.
• Discovery rule in some latent-injury cases. A limited set of injury types (certain head injuries, latent soft-tissue conditions) can qualify for a discovery-rule start in some states, which runs the clock from the date the injury was discovered or should have been. This exception is narrower than most consumers assume.
• Minors are often tolled until the age of majority. The specific mechanic varies by state and by claim type; some states cap the toll at a certain number of years regardless of age.
• Wrongful-death cases typically run from the date of death. Not from the accident. In cases where the injured party survives the accident but later dies of injuries, the wrongful-death clock usually starts on the date of death, which can be well after the ordinary tort SOL has run on the underlying injury claim.

How the policy itself can shorten the clock

State SOLs set the outer limit for how long a claim is alive. The insurance contract can shorten that period within limits set by state law. Three mechanisms do most of the shortening in practice.

State law varies on whether a contractual shortening is enforceable. Some states invalidate suit-limitation clauses that run below a statutory floor; others enforce the contractual period as written. A short practical rule: if the policy says you must sue within one year, treat that as the operative deadline and verify at the state DOI only after you have calendared the shorter date, not the other way around.¹²

Carrier subrogation runs on its own clock (not the insured’s), which creates a parallel set of deadlines the insured rarely sees. For the subrogation side of the same claim, see subrogation and deductible recovery.

The practical pre-filing checklist

A statute of limitations is a hard deadline. The practical defense against missing one is a short set of habits that cost nothing and preserve every option.

• Preserve crash records from day one. Police report, photographs, witness contact information, medical records from every provider, and a running log of every call and letter with the carrier. Thin records are the most common reason a late-filed claim fails on documentation even when it is in time on the SOL. See how to file a car insurance claim for the baseline filing walkthrough.
• Keep every carrier communication in writing. If the adjuster calls, follow up by email summarizing what was said. The date and content of a denial or a last payment is often the trigger for the first-party contract clock. Oral exchanges are easy to dispute later.
• Calendar both clocks the moment the claim opens. Pick the shorter of the state tort SOL, state contract SOL, and any policy-shortened suit window, and set a reminder 90 days before. If the facts shift (new injury discovered, UIM claim added), recalendar.
• Send a written demand well before the deadline. A demand puts the carrier on notice, creates a paper trail, and often prompts a denial letter that fixes the start of the first-party clock. See the claim process timeline guide for how a demand fits into the broader claim arc.
• If you are near the deadline, file suit even without finalizing damages. A complaint can be amended; a time-barred claim cannot. Serious-injury plaintiffs routinely file protective suits with incomplete damages workups because filing stops the clock on everything that has already accrued.
• Do not rely on an open negotiation to keep the clock from running. Carriers are not required to remind you of the SOL and generally will not. Settlement talks continue until the clock runs out, and the claim dies the next day.

For the broader context around what happens after an at-fault accident vs a not-at-fault one, see our at-fault accident guide and not-at-fault accident guide. Both are structured around the deadlines on this page. Property-damage disputes that run in parallel are often best addressed through the policy’s appraisal mechanism; see the appraisal clause explainer for whether invoking appraisal affects the suit clock.
