Claims mechanics
Car insurance claims
A car insurance claim is the formal request to your insurer (or another driver’s insurer) to pay for a loss your policy covers. The outcome depends on three things: whether the policy and endorsements cover the loss, who the state’s rules assign fault to, and the specific limits and deductibles on each piece of coverage. The pages linked below cover the mechanics insurers use once a claim is open. For the step-by-step process of actually filing, see how to file a car insurance claim. For what to do immediately after a crash, see car insurance after an accident. For total-loss settlement mechanics, see car insurance when your car is totaled.
The claim lifecycle
Most auto claims move through the same four phases. The pages in this family explain the mechanics the carrier applies at each step; the state DOI’s consumer-affairs team is the backstop if a step goes wrong.
| Phase | What happens | Where to read more |
|---|---|---|
| 1. Report | You notify the carrier, assign a claim number, confirm the covered-loss type (collision, comprehensive, liability, UM/UIM, PIP), and schedule inspection. | How to file a claim |
| 2. Investigate | Adjuster inspects the damage, reviews the police report if any, and determines fault (in tort states) or routes to PIP (in no-fault states). | Accident when you’re not at fault · At-fault accident |
| 3. Resolve | Repair at a chosen shop, replacement check for a total loss (ACV minus deductible), or payment to a third party under liability. State-specific valuation and deductible rules apply. | Car totaled · Diminished-value claims · Appraisal clause |
| 4. Recover or appeal | Subrogation (your carrier pursues the at-fault party to recover payouts and your deductible); appeal if the carrier denies; or escalate to a bad-faith claim when the pattern goes beyond a single wrongful denial. UIM claims open a separate first-party track against your own policy when the at-fault driver was underinsured. | Subrogation · Denied-claim appeals · Bad faith · UIM claim process |
Should you file a claim?
Not every covered loss should be filed. The decision depends on the dollar size of the damage relative to your deductible, who is at fault, and your carrier’s surcharge posture. The pages below walk the math.
- Should I file a car insurance claim? (the deductible-vs-damage decision framework).
- What if repair cost is less than the deductible?
- Will my insurance go up after a claim?
- Do I pay the deductible if I’m not at fault?
- How much more car insurance costs after an accident.
Claims-mechanics guides
Diminished value claim
Diminished value is the resale-value loss a vehicle carries after a repaired accident. First-party DV is generally excluded by the standard policy outside Georgia (per State Farm v. Mabry, 2001). Third-party DV is a tort claim against the at-fault driver in most states.
Subrogation and deductible recovery
How your insurer recovers from the at-fault party after paying your claim, and when your deductible gets refunded. Timeline, partial-recovery allocation, Arbitration Forums inter-carrier arbitration, and state DOI escalation when the carrier won't refund.
Claim denied: appeal steps and rights
A denied claim is not the end. Six common denial reasons mapped to the right escalation step: written denial, policy-provision review, internal appeal, state DOI complaint, civil litigation. NAIC model regulation on unfair claims practices and state DOI complaint rights.
Appraisal clause: ACV and repair-cost disputes
The appraisal clause lets either side demand independent appraisal when the insurer and insured disagree on the amount of loss (ACV in a total loss, repair cost in a partial loss). Two appraisers plus an umpire. Scope is amount only; coverage disputes stay with the court or DOI.
Bad faith: doctrine and remedies
Bad-faith is a pattern-of-conduct doctrine (unreasonable delay, inadequate investigation, failure to settle within limits) distinct from a single wrongful denial. Where state law recognizes it, bad-faith opens extra-contractual damages beyond policy benefits. State availability varies.
UIM claim process: underinsured-motorist claims
UIM is a first-party claim against your own policy when the at-fault driver's liability limits are insufficient. The three procedural traps are consent-to-settle, subrogation waiver, and separate statute of limitations. Stacking vs reduction rules are state-specific.
Statute of limitations: filing deadlines by state
Two clocks run on an auto-insurance claim: a contract SOL for first-party claims against your own policy, and a tort SOL for third-party suits against the at-fault driver. They are set by different state statutes, run different lengths, and start on different dates. Missing either usually ends the claim.
Supplemental claim: hidden damage after teardown
A supplemental claim is the shop's request for additional funds when teardown reveals damage the appraiser could not see. State prompt-pay rules set the approve-or-deny window; OEM-parts statutes shape the supplement scope. Dispute paths escalate through the appraisal clause and the state DOI.
What this family covers
Four claim-mechanics categories organize the family. The hub cards below describe the scope so you can see what belongs here even if a given leaf has not shipped yet.
Filing and process
How to report a loss, work with the adjuster, review repair estimates, and close the claim. See /guides/how-to-file-a-car-insurance-claim and /guides/claim-process-timeline for the step-by-step.
Total loss and settlement
What happens when the car is totaled: ACV math, lender payoff, GAP, and state salvage retention. See /situations/car-totaled for the full walkthrough.
Carrier mechanics
How insurers recover money from an at-fault party (subrogation), how they treat ambiguous repair bills, and what happens when a claim is denied.
Specific damage types
Diminished value, UIM (underinsured-motorist) claims, hit-and-run, and glass. Each has its own mechanics worth knowing before you file.
