If you own the home, he has no property interest. And if there is no lease agreement, he really doesn't have a legal right to reside there but for your generosity. You may want to check with the Sheriff or DA or attorney that you retain, to see if you can do a criminal trespass warning after demanding in writing that he leave the residence. Then if he returns it would be a misdemeanor trespass. Not sexy but could get his attention.

With that said, you could be estopped from taking action since you've allowed him/them to reside there. It would be nice if you had your agreement for the expenses. He/they would be in breach and that could help.

Totally not my area of expertise nor advice. Just some thoughts.
