The easy answer is two years. But, that is not the legal answer. The legal answer involves a review of a state statute and a little bit of case law. The limitations periods in Texas are set out in the Texas Civil Practice & Remedies Code. So, that is where we start.
Chapter 16 of the Texas Civil Practice & Remedies Code provides in pertinent part that a person must bring suit for personal injury not later than two years after the day the cause of action accrues. Pretty simple, right? Almost. The statute does not say when the cause of action accrues, it only says that you have two years from the accrual date.
