I'm assuming you want the home and mortgage in your husband's and your name as opposed to you and this other person?
If so, then the proper way to do it is most likely to refinance and remove the other person from title and mortgage and add your husband on.
This will help avoid any transfer taxes on the sale of the home, if applicable.
Now if there is equity in the home that you owe the other person, then you would have to try to do a cash out transaction or settle with him in a different way.
Hope this helps!
