IN THIS CAR ACCIDENT CASE, PLAINTIFF RAISED A QUESTION OF FACT WHETHER THE RELEASE SHE SIGNED WAS THE RESULT OF MUTUAL MISTAKE CONCERNING THE EXTENT OF HER INJURIES (FOURTH DEPT). ​

The Fourth Department, reversing Supreme Court, determined there was a question of fact whether the release signed by plaintiff after a car accident was the result of mutual mistake. At the time plaintiff signed the release it appeared her injuries, including whiplash, involved only her cervical, thoracic and lumbar regions. After signing the release she was diagnosed as having suffered a mild traumatic brain injury:

… [I]nasmuch as the submissions indicate that plaintiff had been diagnosed with neck and back injuries only at the time she signed the release and that plaintiff’s symptoms were not medically attributed to postconcussive syndrome until after the execution of the release with additional uncertainty in the interim, we conclude that plaintiff raised an issue of fact whether, at the time the release was executed, the parties were under “[a] mistaken belief as to the nonexistence of [a] presently existing injury,” i.e., a traumatic brain injury … . We therefore … reinstate the complaint. DiDomenico v McWhorter, 2024 NY Slip Op 02634, Fourth Dept 5-10-24

Practice Point: A release signed when both parties are not aware of an existing injury may be invalid as the result of mutual mistake.
