When the other driver's insurer denies your claim

A denial from the other driver's insurer does not end your claim. It tells you which of two different problems you have: either the insurer says its driver wasn't responsible (a liability denial), or it says the policy won't pay for this crash at all (a coverage denial). A liability denial is an argument you can answer with evidence. A coverage denial usually moves you to other sources of money: your own collision or uninsured motorist coverage, another policy that may cover the driver or the car, or the driver personally. In both cases the deadline for suing keeps running while you negotiate.

Two denials that sound alike and work differently

Read the denial letter or note the adjuster's words carefully, because the next step depends on which one you received.

The same letter can contain both ("our driver was not at fault, and in any case coverage is under review"). Ask the insurer to state each ground separately and in writing.

Your claim against the other driver is a third-party claim: you are not the insurer's customer, so it owes you fair handling rules set by your state, but it does not owe you what it owes its own policyholder. The difference is explained in first-party vs third-party claims.

If the denial is about liability

The insurer is not a court. It forms an opinion from its driver's account, any police report and photos. That is the opinion you are trying to change, and it changes with evidence. Many of the same techniques apply whether you are the one being blamed or the one blaming; how to contest your insurer's decision that you were at fault covers evidence gathering in detail. For a claim against the other driver, focus on these points:

1. Ask for the specific reason. "What facts does the insurer rely on in concluding its insured was not at fault?" A vague denial ("investigation shows no liability") is different from "our insured says you changed lanes."
2. Match the story to physical evidence. Photos of final rest positions, skid marks and the damage pattern can contradict a driver's account. Video from a dash cam, a doorbell or a business is the strongest tie-breaker.
3. Use the police report carefully. A citation issued to the other driver helps. A report that blames no one does not mean no one was at fault. If it has a factual error, ask the department how to submit a supplement.
4. Identify independent witnesses and get a short written statement while memories are fresh.
5. Put it all in one organized letter (see the demand letter below).

Fault is a legal question, and the answer depends on your state's negligence rules. In most states a driver who is partly at fault can still recover part of the damages; in a few, any fault by you can bar the claim. Check which applies before you accept a split. comparative vs contributory negligence has the details.

If the denial is about coverage

Coverage denials take several forms. Each has different workarounds.

The policy had lapsed or been cancelled

The insurer says the policy was not in force on the date of the crash. This is a question of notice and payment history, and insurers do not always win it. Your state's cancellation statutes require advance written notice, and an insurer that cannot prove it sent a valid notice may have to cover the loss. The details are in claim denied because your policy was cancelled or lapsed. As the third party you will probably not see the insured's account, so ask the insurer for the policy period it relies on, and ask the driver for the cancellation notice.

The driver was excluded

Some policies list a person as an excluded driver, usually at renewal to lower the premium. If an excluded driver is behind the wheel, the insurer may deny the claim entirely. Whether that denial holds against an innocent third party varies by state, because financial responsibility laws and policy wording interact differently from place to place. Do not assume it either way; check with your state's insurance department or an attorney.

The driver did not have permission

Most auto policies cover permissive users, meaning someone the owner allowed to drive. If a thief or someone who took the car without consent caused the crash, the insurer may say the driver was not covered. The vehicle owner may have separate liability for negligently allowing access, depending on the state. The key facts are who gave the keys, whether there was a history of lending the car, and whether the owner reported it stolen. See permissive use.

The insured breached a policy condition

Policies require prompt notice and cooperation. An insurer sometimes denies coverage because its insured reported late, stopped answering calls, or lied on the application. These are disputes between the insurer and its customer, and their effect on an injured third party depends on state law. For the application-lie scenario, see misrepresentation and rescission: can an insurer void your policy?.

The car was being used in a way the policy excludes

Business deliveries, ride-hailing with the app on, and racing are common exclusions. If the driver was working, a business or commercial policy may apply; ask whether the driver had an employer or a platform policy.

The driver was not insured by this company at all

The other driver may have given you the wrong company or an expired card. Verify through the police report, the state's insurance verification system, or the registered owner. NAIC notes that you generally file with the at-fault driver's insurer and that insurers are expected to pay claims promptly, and recommends contacting your state insurance department for questions it does not cover (NAIC auto insurance consumer page).

Your own coverage is the fastest route to repairs

You do not have to wait for the other insurer to change its mind. Your own policy can pay first, and your insurer can then pursue the other side through subrogation.

• collision coverage pays to repair your car regardless of who caused the crash, minus your deductible. New York's Department of Financial Services, for example, tells policyholders that their insurer must inspect the car and make a good-faith offer within six business days of notice if the car is available, and must pay within five business days after a settlement is agreed (NY DFS). Timelines vary by state.
• Uninsured motorist property damage may pay instead of collision in some states, sometimes with a smaller or no deductible. uninsured motorist property damage vs collision: which to use explains the trade-off, and uninsured motorist property damage defines the coverage.
• uninsured motorist coverage (bodily injury) can pay for your injuries when the at-fault driver has no valid insurance. Many state laws and policies define an "uninsured motor vehicle" to include one whose insurer denies coverage or becomes insolvent, but the wording differs, so read your policy's definition and ask your insurer in writing whether a coverage denial qualifies. what to do after an accident with an uninsured driver covers the claim steps.
• Medical payments or PIP pays your own medical bills first in many states, whoever is at fault.

Using your own coverage can feel like giving up, but it is the usual way to get a car repaired while the dispute continues. Your deductible may be recoverable later if your insurer collects from the other side. How that works is explained in do you pay a deductible if the accident was not your fault?.

The Insurance Research Council estimated that 15.4 percent of U.S. drivers were uninsured in 2023 (III, citing the IRC's 2025 study), which is one reason UM coverage matters even for careful drivers.

Send a demand letter that makes a decision easy

A demand letter is a written request for payment that sets out what happened, what you are owed and by when. Insurers respond to organized files. A short, factual letter often changes an outcome that phone calls did not. Include:

1. Your name, address, claim number, the date and place of loss, and the other driver's name and policy number.
2. A concise statement of facts, in order, without insults.
3. The reason the other party is legally responsible (the rule broken, such as failing to yield or following too closely).
4. An itemized list of damages with proof: repair estimate or invoice, towing, storage, rental or loss-of-use costs, and, if injured, medical bills and wage records.
5. Attached evidence, each item named: photos, video, witness statements, the police report.
6. The amount you are demanding and a reasonable response date, such as 30 days.
7. A statement that you will pursue other remedies, such as small claims court, if the insurer does not respond.

Send it by a method that proves delivery (certified mail with return receipt, or email with a read confirmation plus a mailed copy). Keep copies and a log of calls. If you are hurt, speak with an attorney before sending a demand covering injuries; settling an injury claim can close it permanently.

Releases

Do not sign a release that is broader than the payment. A release for property damage should cover only that property damage claim. New York's Department of Financial Services has issued guidance that an insurer cannot require a third-party claimant to sign a release broader than the scope of the settlement (NY DFS opinion 11-04-01); other states have their own rules. If a release mentions "all claims, known and unknown," stop and have it reviewed.

What a third party cannot demand

Knowing the limits saves effort.

• You usually cannot sue the other driver's insurer directly. In most states you sue the driver; the insurer defends and pays within policy limits. A few states allow suits against the insurer in limited circumstances, and those laws change, so check your state before relying on it.
• You cannot see the insured's statements or the insurer's internal claim notes before a lawsuit, though in litigation you can ask for them in discovery.
• You cannot demand more than the policy limits from the insurer. If the damage exceeds the limits, the remainder is a claim against the driver personally.
• You cannot force the insurer to pick a repair shop or pay a particular price. You can choose your shop and ask the insurer to pay a reasonable cost, backed by estimates.
• You cannot bring a bad-faith claim for how the insurer treated its own insured in most states. That claim belongs to the policyholder.

You can insist on fair claims handling. The NAIC's model regulation on unfair claims settlement practices, which many states adopted in some form, requires insurers to acknowledge claims within 15 days, to give written denials that cite the policy provision, and to tell unrepresented claimants when a time limit is about to expire (NAIC Model Regulation 902). California's rule is comparable: an insurer that denies a third-party claim must say so in writing and must accept or deny within 40 days under 10 CCR 2695.7. Whether your state has these rules, and what they say, is a question for your department of insurance.

Small claims court or a lawsuit

If the insurer will not pay, the next step is a lawsuit against the at-fault driver (and sometimes the vehicle owner), not the insurer. For property damage within the court's limit, small claims is designed for people without lawyers. Limits vary widely: California allows $12,500 for individuals, Florida $8,000, Kentucky $2,500, New York City $10,000 and Texas justice courts $20,000 including attorney fees, each according to court sources checked in October 2026. Check your court's current limit, because they change.

A practical sequence:

1. Confirm the defendant's name and address. Use the police report, the registered owner record, or the insurance card.
2. Pick the right court based on where the crash happened or where the defendant lives.
3. File with your evidence organized: estimate, photos, receipts, the demand letter and proof it was sent, and the denial.
4. Serve the papers the way the court requires.
5. Bring witnesses and exhibits to the hearing; judges decide quickly.

If you win, the insurer often pays when its driver is covered, or the court enters a judgment against the driver. A coverage denial means the judgment is the driver's personal debt, which may be hard to collect. Some states can suspend a driver's license over an unpaid auto judgment, but check your state's rules. small claims court for car accident damages: limits and evidence covers limits and evidence in more detail, and small claims court after a car accident is the shorter guide.

For injuries, large repair bills, disputed fault between several drivers, or a possible coverage dispute, a licensed attorney is the right person to advise on the sequence. Many handle auto injury cases on contingency.

Watch the clock

Deadlines are the most expensive mistake in this process. The statute of limitations is the last day to file suit. Negotiating with the insurer, or waiting for a response to your letter, does not stop that clock in most states. Limits range from one year in Tennessee to six years in Maine, Minnesota and North Dakota for injury claims, with two or three years most common, and property damage deadlines often differ (statutes of limitations for car accident claims lists every state). Some claims have shorter notice requirements, for example claims against a government vehicle or your own insurer's UM coverage, where the policy may have its own time limit. Put the filing date in your calendar the day of the crash.

A worked example

Say you are rear-ended at a red light. The other driver's insurer calls two weeks later and says its insured claims you reversed into her car, so it denies liability. Your repair estimate is $6,200 and your collision deductible is $500.

1. You send your photos and a nearby gas station's video, which shows her car rolling forward while yours is stopped. You write a demand letter attaching them and asking for $6,200 within 30 days.
2. You also open a claim under your own collision coverage so the car can be repaired now. You pay the $500 deductible. Your insurer pays $5,700 to the shop.
3. Your insurer sends the video to the other insurer and pursues reimbursement. If it recovers the full amount, you get the $500 deductible back.
4. If both insurers still disagree, your insurer can take the dispute to inter-company arbitration, as described in inter-company arbitration: how insurers settle claims among themselves.
5. If no one pays and you have a deductible loss, small claims remains an option for the $500, within the filing deadline.

The numbers are hypothetical, but the sequence shows how the two tracks (your claim and the recovery) run in parallel.

Questions to ask the other insurer

• "Is this a denial of liability, a denial of coverage, or both? Please state each ground in writing."
• "What policy period and what coverage are you relying on?"
• "What evidence supports your insured's version of events?"
• "Is there another policy that may apply, such as the vehicle owner's, a household member's or an employer's?"
• "What is the date by which you will complete your investigation?"
• "Please send me the name of the adjuster, the claim number and the department's contact for complaints."

Common questions

Can I get my medical bills paid while the denial is being sorted out?

Often yes, through your own PIP, medical payments coverage or health insurance. The other insurer's denial does not stop those. You may have to repay your health plan from any later settlement, so keep the paperwork.

What if the insurer says its driver was not the one driving?

That is a factual dispute about identity or permission. The police report, the registered owner, witnesses and any video are the evidence. If the car's owner was negligent in allowing someone to drive, the owner may be liable under state law, so ask whether the owner has separate coverage.

Does the insurer have to tell me why it denied my claim?

In many states a third-party denial must be in writing and explain the reason. Ask for it. NAIC's model regulation calls for written denials citing the provision, but adoption differs by state.

Should I contact the department of insurance?

You can, especially if the insurer is not responding within your state's time limits or cites a reason that seems unrelated to the policy. Regulators can look at whether the insurer followed claims-handling rules. They generally do not decide who was at fault, so keep building your evidence at the same time.

Key takeaways

• Work out whether the denial is about fault or about coverage; they have different fixes.
• Use your own collision, UM or medical coverage to move forward while the other claim is disputed, and ask your insurer to pursue the recovery.
• Send a documented demand letter, avoid broad releases, and keep proof of delivery.
• You usually sue the driver, not the insurer; small claims courts handle smaller property claims, and a licensed attorney can advise on injuries and coverage fights.
• The statute of limitations keeps running during negotiations, so calendar your state's deadline early.
