A (recent) ex-boyfriend just filed an "intent to file a mechanic lien" against my house for $3,000 worth of labor hours/purchased materials. The house is in my name and I bought it when we were still together in October of 2019. My ex is claiming that we had a verbal contract stating I would pay him back for these items, however the conversation we had was that I assumed all the household bills including rent and utilities, and we both contributed towards paying for materials, groceries, etc while working on projects together after he got off work and I got out of school. There was never a written contract because--at the time--we both enjoyed improving our mutual living space. I believe my ex is filing this lien against me because he is angry that the relationship is over and he wants to hurt me. I told him that I was considering selling the house because there were too many memories in the space and that was when he said that I would have a hard time selling it with a lien on the property... How should I proceed? Thanks for your time. -Nate
