How do you go about getting a car back that you cosigned for if the other person is not making payments?

YES, you can include it whether the payments are current or not.

Pay the loan off and then collect payments from the person you cosigned for.

Cosigning for ANYONE is one big mistake. If the person you cosign for is not making the payments then the person that cosigned is responsible for all payments. I have no idea why anyone would want to do this. Unless there were stipulations in the contract you signed with the buyer, then no, they can't just up and sell the car. Take another look at your contract. Marcy

Contact whomever holds the lien, they will allow you to make payments and take posession of said vehicle if signor has ceased to make payments. I have already contacted the lien holder and they advised me that they would not get involved with me taking possession of the vehicle. All they wanted from me were back payments. I brought the payments up to date. Now I want to get the vehicle in my possession. Unfortunately I have been unsuccessful at contacting the person I cosigned for. I've even heard that he may have moved out of Michigan. I have a copy of the Michigan registration showing myself as an owner. I am currently awaiting documentation from the state that I am on the title. What is my next step towards getting possession of the car?

If a person's name is listed on a title, that person owns the car. If a person merely cosigned the note, that person's name will not be on the title. If you own the car, you certainly can take physical possession of it.
