My mother owns a home in Palm City, Florida. She still has a mortgage on it at 83 years old. She would like to add me to the deed. How do we go about that?

Here is a setting of instructions from an earlier post https://www.askmehelpdesk.com/real-estate-law/how-add-someone-your-deed-569716.html. You need to contact the mortgage holder too.

Except in the case of a spouse, one doesn't add a name to a deed. One transfers ownership from the current titleholder to the new titleholders. Since this is a transfer of ownership, there are legal and tax implications involved.
