If the title to your house is currently in both names, I will be shocked if the mortgage lender is willing to let you refinance the mortgage in your name alone. It is not uncommon for people to put the title and mortgage in one persons name because the other party has poor credit. If the purpose of refinancing the mortgage is to get a lower interest rate AND the mortgage lender says that title needs to be in your name alone as well, then sign something with your spouse, saying that the transfer of title from joint name into your name alone is purely for purposes of getting a lower rate on the mortgage and will not effect his ownership interest in it. Then, in the future, if you do decide to go forward with a divorce and want to keep the house, title and the mortgage is already in your name alone and at that point, you and he can figure out how you buy out his equity interest in the property ( cash buyout / trasnfer of other retirement monies, etc) but you will not need to refinance the mortgage again nor incur additional costs for keeping the house.
