Yes, you can usually file a diminished value claim against the at-fault driver's insurer. Diminished value is the drop in market value that remains after repairs, the pre-accident value minus the post-repair value with an accident history.
Even complete repairs leave a market penalty because buyers pay less for a crash history. The Texas Department of Insurance explains this gap in Commissioner's Bulletin B-0027-00. Most owners must pursue the at-fault driver's insurer, not their own collision policy.

Who do you file against?
File as a third-party liability claim. That means you demand payment from the at-fault driver's liability insurer. A first-party claim against your own collision coverage is generally not owed under standard repair-or-replace language, according to the same Texas Department bulletin.
Identify the at-fault driver and that driver's insurer early. Send your demand to that insurer, not your own. If fault is shared, your recovery can shrink or fail.
Why do Georgia, California, and North Carolina differ?
Georgia is the major exception. The Supreme Court of Georgia held in State Farm v. Mabry that a promise to pay for "loss" covers post-repair diminished value. The court required insurers to assess it when a policyholder makes a physical-damage claim, as shown in the State Farm v. Mabry opinion. California takes a different path.
The California Legislature provides in Civil Code Section 3333 that a non-contractual wrong pays for all directly caused harm. Courts apply that rule as repair cost plus any remaining loss in market value when repairs cannot fully restore value. North Carolina adds a dispute procedure. The N.C. General Assembly requires auto liability policies to offer appraisal for disputed diminution in value when liability is undisputed. The process triggers when estimates differ by more than $2,000 or 25% of pre-accident retail value, under the Senate Bill 660 text.
How long do you have to sue?
Deadlines are strict and vary by state. In Texas, a property-damage suit generally must start within two years of accrual, under Civil Practice and Remedies Code Section 16.003, according to FindLaw's page for the Texas property-damage deadline. In California, the Autoloss California guide updated for 2026 notes a three-year period for this type of claim.
Do not wait for the insurer to finish negotiating. File or formally preserve your lawsuit before the deadline passes. A late filing can end the claim even when fault is clear.
What proof wins payment?
Build a paper trail before you demand money. Hartley Law's Texas filing guide says successful claimants gather pre-accident condition proof, repair invoices, photos, and an independent appraisal comparing market values. Send a written demand to the at-fault insurer with those documents.
State the amount, attach the appraisal, and keep proof of delivery. If the insurer denies or lowballs, you can sue the at-fault driver or use appraisal or small-claims procedures where available. Keep copies of every estimate, photo, appraisal, and letter. Send the demand in writing and track the response date against your filing deadline.
