I am moving in with my boyfriend. He was raised by his grandma, and lived in her home his entire life. When she died, the house was left as follows, one third to an uncle, one third to the second uncle and the final third is split between him and his two siblings. He pays the property taxes and homeowner's insurance. However, with my moving in I would like to have something in writing with his family. My biggest concern is that I would move in there, something would happen to him and his family would lay claim to everything I have as his! Not to mention, any money we start to put into the house to "fix it up" - floors, bathroom repairs, central air, etc. I would prefer to "buy them out" but right now, rent free is too easy! Any suggestions as to what would protect my interests?
