Legal questions about cohabitation

Questioner

My boyfriend and I live together in my (purchased) house. He pays me a fixed amount every month (half of certain fixed costs). Suppose we ever break up, has he built up certain rights because of this?

Lawyer

No. But the law does require that one be reasonable and so you may have to be patient if he needs another home.

Questioner

Okay, clear. Is there still a standard for how much patience is needed, or is it possible for him to spread it out as long as possible?

Lawyer

He is alone so if he can stay with a friend or family member somewhere that is fine, if not a month or three maximum to find a studio or room,
