In the 2 years since separation I have paid over 100k off the mortgage, for a property that my ex lives in. I wanted to keep the property a nest egg but allowed him to stay to help him get back off his feet. He has since filed a claim to have the property transferred into his name and since I received his lawyers letters I have stopped contributing to the mortgage. Now he has too and the bank is calling. If I have paid most of the money and he is living in the property (with a boarder no less), than is he responsible for paying the bank? Will be both have defaults against our names?
