Ask a Lawyer and Get Answers to Your Legal Questions
If the ex-husband wanted to pursue criminal charges - the best thing to do is to contact law enforcement (use the local police or sheriff department's non-emergency number). The statute of limitations for forgery in TX is 10 years for felony forgery.
(See generally: http://www.criminaldefenselawyer.com/resources/forgery-laws-texas.htm).
If this matter is not involved in part of the divorce proceedings (where these kinds of disputes between ex spouses are generally handled), the ex husband may be able to file a second civil complaint against the ex wife for conversion and fraud (conversion is the civil equivalent of theft) and get a money judgment to compensate for the loss of the ownership interest in the vehicle.
