Your car is back from the body shop. It looks fine. But when you check trade-in offers, the number is lower than it was before the crash. That gap has a name: diminished value.
This guide explains what diminished value is, how Indiana law treats it, and what to understand before you decide on next steps. It’s written in plain English by Claim Defend Advocacy, an education-focused resource run by Daniel Deines, who has ten years of property claims experience.
What “diminished value” means
Diminished value is the drop in a vehicle’s market value after it’s been damaged and repaired. Even a well-done repair can’t erase the fact that the car now has an accident history, and many buyers pay less for a car with one.
You’ll usually see three terms:
- Inherent diminished value: the loss in value simply because the car has been in an accident, even after a proper repair. This is what most people mean.
- Repair-related diminished value: extra loss because a repair was done poorly or with lower-quality parts.
- Immediate diminished value: the difference in value right after the crash, before repair. This one comes up less often in everyday claims.
The big question in Indiana: whose insurance are you dealing with?
In Indiana, the answer depends heavily on which policy you’re making the claim against:
- A third-party claim is made against the at-fault driver (usually through their liability insurer).
- A first-party claim is made under your own policy, such as your collision coverage.
Indiana’s courts treat these two very differently.
Third-party claims: when the other driver was at fault
When someone else causes the damage, the claim is based on Indiana’s general rules about property damage caused by another person’s fault (tort law). The Indiana Supreme Court has said that under Indiana law, the measure of damages a person can recover from a wrongdoer includes diminution in value. In that discussion, the court pointed to two earlier Indiana Court of Appeals decisions, Dado v. Jeeninga (2001) and Wiese-GMC, Inc. v. Wells (1993).

What that means in plain terms: if another driver was at fault, diminished value is a recognized type of loss in Indiana. It doesn’t mean any particular amount is owed. The at-fault driver’s insurer will look at fault, the vehicle, the repair, and proof of the value loss.
Fault matters. Indiana uses a comparative fault system. If you’re partly at fault, your recovery can be reduced by your share, and if your fault is greater than the fault of everyone else involved, you can be barred from recovering.

First-party claims: your own collision coverage
This is where many people get surprised. In Allgood v. Meridian, the Indiana Supreme Court looked at a standard auto policy that limited the insurer’s payment to the lesser of actual cash value or the “amount necessary to repair or replace” the vehicle. The court held that this language was unambiguous and did not require the insurer to pay for diminished value after a repair. In the court’s words, repair means restoring something “to its former condition, not necessarily to its former value.”

Two practical takeaways:
- Read your own policy. The Allgood ruling was about specific policy wording. Your policy’s “Limit of Liability” and “Coverage for Damage to Your Auto” sections are what matter for a first-party claim.
- If someone else was at fault, the third-party route may be different. That’s a question worth raising with an Indiana attorney.
Deadlines to know in Indiana
Indiana law says an action for injury to personal property (which includes damage to a vehicle) must be filed within two years after the cause of action accrues.

A few cautions:
- That two-year deadline is for filing a lawsuit, not for opening an insurance claim. Insurers and policies can have their own notice and timing requirements, so check your policy and any letters from the insurer.
- When a deadline starts and whether anything pauses it can be a legal question. If you’re getting close to two years, talk to an attorney soon.
What to gather before you talk numbers
Whatever route you’re looking at, organized records make every conversation easier. Here’s a general checklist:
- The police or crash report and the other driver’s insurance information.
- Photos of the damage before repairs, and of the finished repair.
- The final repair invoice, including a parts list (OEM, aftermarket, or used) and any frame or structural work.
- Pre-accident condition records: mileage, maintenance records, recent upgrades, and any recent appraisal or listing.
- Market evidence: comparable vehicles for sale with and without accident history, and written trade-in or purchase offers from dealers.
- Vehicle history report, so you know what future buyers will see.
- A log of every call and email with the insurer: date, name, and what was said.
Some people hire an independent appraiser to document diminished value. If you go that route, ask about the appraiser’s method and fees up front.
Where to get help in Indiana
- Indiana Department of Insurance (IDOI) – Consumer Services. If you’ve contacted the insurer and still believe a claim was improperly denied, delayed, or mishandled, you can file a complaint. The IDOI says it typically processes complaints within 72 hours, and by Indiana law the insurer has 20 business days to respond in writing.

- Related statute: Ind. Code § 27-4-1-5.6 — https://law.justia.com/codes/indiana/title-27/article-4/chapter-1/section-27-4-1-5-6/
- An Indiana attorney. For questions about fault, deadlines, how much to claim, or whether to file in small claims, an attorney licensed in Indiana is the right person to ask.
Frequently asked questions
Can I get diminished value from my own insurance company in Indiana?
Under the policy wording reviewed in Allgood v. Meridian (Ind. 2005), the Indiana Supreme Court said no: a standard “repair or replace” limit doesn’t include diminished value. Your policy’s exact wording matters, so read it closely or ask an attorney.
Can I get diminished value from the at-fault driver’s insurance?
Indiana’s Supreme Court has said that damages recoverable from a wrongdoer include diminution in value. Whether and how much an insurer pays depends on fault, proof, and the facts of the crash.
How long do I have in Indiana?
Ind. Code § 34-11-2-4 sets a two-year deadline to file a lawsuit for injury to personal property. Insurance policies may have separate notice requirements. Ask an attorney if you’re close to the deadline.
How is diminished value calculated?
There’s no single formula set by Indiana law. Insurers, appraisers, and courts may look at market evidence, the vehicle’s age, mileage, and condition, and the type of damage and repair. Be cautious of any one-size-fits-all formula.
Do I need a lawyer or a public adjuster?
Not always, but if the amount is significant, fault is disputed, or a deadline is near, an Indiana attorney can advise you. Claim Defend Advocacy is an education resource only and does not represent or act for anyone on a claim.
