I would think it would be best to leave mom's and MIL's out of the equation. I know that there are situations where it just can't be helped. Such a living situation should be short-term if at all possible. So unless there was a medical or other serious reason why a mom can't live on her own, I would definately already be planning on her moving out, before she even moved in with me and my partner. Now if I'm single, my parents are of course welcome to stay with me for a prolonged period, until they start causing too much trouble. I can't be too harsh about that, seeing as how I'm an adult living with them.
