I lived with a gentleman that I had a child with and owned an automobile with. We have been separated for 5 years (never married) and I have the title to the automobile which is in both of our names. I have been paying for the entire upkeep on the car...taxes, insurance, tires, oil changes, tune ups. etc.....The car is getting older and I need his name off of the title . Is there a legal time limitation that he can no longer make any claim to the car ? He has made no claim thus far but, also will not sign the title so that I can do anything on my own with the car. We lived in a state where we purchased that automobile originally where they used no and/or in the title in that state. We moved to this state and I took the title to transfer it to only my name 5 years ago and low and behold this state defaults to AND between our names ? What do I do ?

Optional Information:
West Columbia, South Carolina

Already Tried:
Asking the other partial owner to sign over the title.
