son. The son has a drug problem, doesn't hold down a job, or have a cell phone and is always on the go. We need him to sign off on some documents so the brother can get the sister's car title and lien release forwarded to him. He paid off the vehicle, and the son has no issue we are sure of him taking the vehicle since he has no money to pay for it. The sister had no estate, she only owned this vehicle. She had no will and nothing passed into probate. What would one do in this situation?
