Tough situation, all the way around. As the three owners, all three of you have the right to possess (occupy) the home. I am not sure this extends to offspring, however. I can foresee all kinds of potential problems, including the ones you have already mentioned. It does not sound like it would be useful to charge him rent, either, as he will either not pay, or he will feel the need to deal, in order to come up with the money to make rent. Is there any way to buy out your sister's share in the property? I am guessing not, because of the disabilities mentioned. I would suggest that the nephew lives with his mother. Maybe she can straighten him out.
