Can I Sue to extend statute of limitation in a personal injury car accident case?

OK so there is no such thing as suing to extend the statue of limitation's. You could file a lawsuit even after the expiration of the time period, but the defendant will interpose the defense that the claim is time barred. Why didn't you get an attorney to represent you? As always, you need to discuss with counsel in your specific jurisdiction regarding matters of civil procedure that may allow you to claim relief from this time period, but it may be a difficult task.
