So, you draw up contracts
This scenario is actually very common, so that’s why we’re covering it. You’ll need to draw up a contract stating, explicitly, what happens if you break up? Divorce? If he dies? If you die? If you divorce, but you have kids? How is this equity being split up? Who will remain in the home? Will neither of you? Will you take on renters then? Or sell? You have to talk about these painful scenarios in detail with a lawyer, to create a contract that will protect both of you. And that’s not really a warm and fuzzy conversation.
