In 2005, boyfriend loaned me the 20% down payment on my home. I thought it was a gift, but right before closing he had me sign an "Equity Contribution Agreement". The Agreement states the money was specifically for the down payment of my home. In 2009, I broke up with him. He then recorded the Agreement. I was not informed that he recorded the Agreement and found out by accident. Currently, I am $100k upside down on my home (not including my ex-boyfriend's lien). The Agreement states that I am to repay the loan upon title transfer, whether it be by sale, foreclosure, deed-in-lieu of foreclosure, etc. Will his lien be subject to AZ's anti-deficiency laws and eliminated if I foreclose on my home?
