Well hang on, here’s a scenario for you: Say I own a 2 bedroom condo, and have a roommate that I charge rent. One day, I meet a girl and we start dating. At some point, said roommate moves out, and it just happens that my gf and I are at the point where she moves in, and said 2nd room gets turned into a office or guest room, because obviously we’re going to share the master. She pays me rent for living with me (might even be a lower amount for whatever reason). After two years, we decide to break it off since it isn’t working between us and she moves out. Do you think I should be expected to pay her out a slice of equity? How is that any different than a roommate renting a room from a financial standpoint?

And in response to your other reply, what if she didn’t contribute to repairs? I think my point here is where do we draw the line? I can understand if a partner makes a significant investment contribution to the property, but I don’t know if I necessarily agree even with a certain length of time outside of marriage without a prenup, considering if y’all were renting somewhere you would have no claim to the property whatsoever. Just because someone is in a relationship with someone, in my mind, does not entitle them to another person’s assets just because they were together.
