I got married in Tennessee in 03... I later found out my wife was not only a cheater but also a thief... which included identity theft on her record... needless to say, I split up with her... I wanted to know if my marriage is legal

Did she use her real name at the time for the marriage license ?

If so and she used the proper information then you are legally married and need to go the normal route of divorce. If a fake name was used then you may be able to use the annulment route to obtain a legal separation of the parties as if it never existed.

No I don't believe she did use her real name

I don't think she did use her legal name... whatever name that may be... thank u so much

i dont think she did use her legal name...whatever name that may be...thank u so much

You will need to find out who she is. Then with that information pursue it in court. The rules are different when there has been fraud.
