Legally, I have no idea. However, having lived in my wife's house without my name on the mortgage for awhile, I might be able to provide her point of view. If she was bringing in income, contributing to the utilities and bills, helping to pay for the upkeep, doing repair work or otherwise contributing to your living/lifestyle during this time, I can understand it. For example, if you agreement was that you paid the mortgage, but she paid for all the food for the three of you, I could see how she thinks she is getting the raw end of the deal. After all, you could pay for the mortgage because she was covering the food. You get the house and she gets what? full tummys and proper nutrition for you all, but nothing material. Or if she was covering the health insurance...or the utlity bills. Essentially, if her money was going into the living expenses, it seems like semantics if you paid the mortgage and if she paid for everything else to make it work. I was confused by the statement I bought the property cash, and I pay the mortgage. I was unclear if that meant you paid the down payment in cash and then continued with the mortgage or it is all paid off in cash? And after living someplace for 8 years, I would it home too.
