My question involves estate proceedings in the state of: California
My wife recently passed away. I am in a legal battle with her son from a prior marriage. She owned a vehicle that was her separate property before we got married, but after we were married, she went to the dmv and changed ownership to both of us on the registration and pink slip. I also did the same with my vehicle, but it was sold while we were married and before she passed away. We both assumed that this was all that was needed in order for joint ownership. She had a will that left the vehicle to her son and he is saying the transmutation was not properly done. Do I have spousal survivorship rights to this vehicle, or does the son have rights because he was named in the will? Or is the value to be split between us? I thought that if title is legally changed to include both husband and wife that it becomes a jointly owned asset, but now I am confused. Thank you so much.
