This is law from in the state of Indiana.

I co-signed for someone, for a motorcycle. But this transaction was through a credit card. Since it was through a credit card he was the only one who signed the entire purchase receipt. Though for the loan to go through my name had to be on the title. The co-signer went deliquent in december. I have tried many times making negotiations with him. Until finally I stated if he signs over the motorcycle to me so it can he sold, and pays $630 of the of what I paid while it was in his possession. I will take care of the rest of the loan. He informed me the clutch was loose on the motorcycle, which was false and information he knew of before hand. It has hundreds of dollars in damage. This damage was done because he went behind my back and gave it to his roomate. I told him he has to either pay for the damages, since it can not really be sold as is without an extreme drop in price, or he has to get the money from his roomate. He is refusing to give any of the money, even though $430 of it was a signed and noterized contract, he also has yet to sign over the motorcycle. He did sign a paper stating he relinquishing his right to it so it can be sold, I unfortunately cannot find that paper, but even if I could I was informed the only way he could do that is by signing over the title. Until the title is signed over I cannot sell the motorcycle. He has even made threats to me, such as filing bankruptcy and calling the cops for theft. (all of which has been saved). I sent him a letter certified mail stating all conditions he has to meet which was all stated above and he sent me a text that day stating "Ha ha ha..." (also saved) Which I also informed him any contact will be saved and used against him in court, in the certified letter. I know of other claims he has against him for two separate banks that went to collections against him as well. I was told since he is the only one who signed the purchase receipt, I have a right to sue him from one lawyer. I wanted to confirm this was correct. I also wanted to find out if so far I am building a good case.
