My Mother passed away and she was a co sighner on my loan they added her to my title how do i get her off my title
It depends on how she is on the title of the house, i.e., jointly, tenants in common, etc.
You will need to take the deed to an attorney to review and advise. It could be as simple as recording a death certificate, or it may require probate.
Are you asking about a real estate title or a car loan? If she co-signed on a note for your house she is probably not on the title to your house. If she co-signed for your car - give them a copy of her death certificate.
