Legal Question in Family Law in Massachusetts

Thank you for your question. This is a tough situation, and it is going to be even more difficult because you and the other individual did not write down your agreement or understanding. Whatever it is or was, at least you would have known where you stand. In the eyes of the law, you are most likely going to be considered a tenant. I'm not clear whether the intention was to add your name to the title of the home, a cosigner on the loan, or other. You may want to write down a timeline and history and sit down with an attorney. You may have certain equitable claims over the property, essentially on the basis of "fairness", but those claims are difficult and would be entirely dependent on the specific facts of your situation.
