My best friend was married 10 years ago and she doesn't know if her divorce was ever finalized.. she never signed anything to that effect. Her ex told her he took care of everything but now she is not sure. It was not a good separation. She has now been re-married for a year and the topic of bigamy came up and scared her a bit.
What is her best way to find out if in fact the divorce was ever done? What was it that he could have done to not need her signature?
