Diminished value claims in Connecticut

Can you claim diminished value in Connecticut?

Short answer: Yes, from the at-fault driver's insurer.

Third-party: the Connecticut Supreme Court said in Orlando v. Liburd (Jan. 6, 2026) that its case law clearly establishes a plaintiff's right to recover loss of use and diminution in value even if the vehicle has been repaired, citing Littlejohn v. Elionsky (1944), which noted a repaired car may be worth much less than before the collision. The same case held an injured owner's own insurer can be liable in unjust enrichment if it takes the at-fault driver's limited property-damage limits by subrogation before the owner is made whole for DV and loss of use. The general measure is the difference in value immediately before and after the collision (Damico v. Dalton, Conn. App. 1983, where repair cost exceeded that difference and was disregarded). First-party: no Connecticut decision was found.

• After: get at least two written trade-in or purchase offers from dealers who see the repaired car and its history report.
• Keep the repair invoice, photos of the damage and the history report entry; they show what a buyer will see.

Will the insurer use the 17c formula in Connecticut?
