Good question and I don't have an answer. Except that I do know that you don't have the power take your wife off any legal agreement or document without her agreeing to it or a court order or stipulation that she will no longer be on the deed or mortgage. In most cases, a home is owned 50/50. Couples divorcing sell the house, pay off the mortgage,share the expenses and profit and move on. In other situations, one spouse buys the other out. Most people do not have enough money to buy someone's 50 percent ownership of a property without refinancing. My son just went through this. He had to get an interest only loan, but I think the rate was about 6.25, but they have a very high credit score. Do some research about Family Law in your state and how property is divided. She may also be entitled to a portion of your pension or 401(k), but then again you may be entitled to a portion of hers if she has one.
