Giving even more thought to the matter, do you have any water or electric bills from Texas during the time you are being extorted for in Indiana? If you can show some receipts which show you paid Texas sales tax, you have proof that you were paying taxes in another state along with your DL which Texas would not grant to non-residents. I realize that the burden of proof is on you in tax court. I don't think it would be unreasonable to contact the state of Indiana and ask them to put in writing or to direct you to where you could find a description of the conditions which would prove you weren't a resident of Indiana. I think the Tx license and proof of paying sales tax should do it unless there is something I don't know about that would allow them to claw back. Someone I don't like once said that lawyers don't want to solve your problems because once they do, the money stops coming in. I do not like this person but that doesn't change the fact that he is right. Lawyers need as much supervision as you would give a 16 year old.
