My husband and I bought a house 14 years ago . We both are on the mortgage with me being the primary on the mortgage , but my husband name is only on the deed . How do add my name to the deed since we both are paying the mortgage

Why wasn't that done when you bought the home? Just have him do a quit claim deed from him to you both.

At the top of the Real Estate Law Forum there is a sticky post that explains how to add someone to a deed. You can read it at https://www.askmehelpdesk.com/real-estate-law/how-add-someone-your-deed-569716.html
