Can You Reopen a Texas Car Accident Claim After Signing a Release If Your Injuries Get Worse?

Direct Answer Under Texas Law

Almost NEVER! Under Williams v. Glash, 789 S.W.2d 261 (Tex. 1990), standard Texas insurance releases explicitly cover 'all known and unknown, foreseen and unforeseen bodily and personal injuries and the consequences thereof.' Once you sign a full bodily injury release—even if an adjuster paid you $1,500 two days after the crash and you find out 3 months later that you need a $120,000 cervical spine fusion—your claim against that driver is permanently barred forever unless you prove actual extrinsic fraud or lack of mental capacity.

Critical Texas Procedural Trap to Watch Out For

'Swoop-and-Settle' Adjuster Tactic: Some insurance companies send field adjusters or DocuSign links within 24–48 hours of a crash offering $1,000 to $2,500 'inconvenience money' plus an open medical promise—buried inside a binding Full and Final Release of All Claims!

Recommended Action Plan for Texas Claimants

NEVER sign a bodily injury release or accept a digital 'quick-settle' payment in the days or weeks following a crash before your doctors confirm you have reached Maximum Medical Improvement (MMI).
