How can I legally remove my adult child from my home?
How can I legally remove my adult child (who was previously a minor child in my custody) from my home? As I understand it, since he has lived with me under my care, my house is considered his legal address and he is appointed all the rights that that entails. He won't leave even though he has been "kicked out" by me and my wife. Are there any legal means of removing him and making sure he does not return?
If he is not paying you rent, then he is a guest or invitee; you may serve him notice to quit or leave (I think it's a 3-day notice) and then if he doesn't, you can bring an eviction action against him.
If he is paying you rent, then he's a tenant. (And note: this could include regular contributions for food, utilities, etc.) However, if there's no written lease, he's a tenant at will, which is a month-by-month tenant, so you could give him 30 days notice to leave and when he doesn't, evict him.
Once evicted, he has no right to return unless you choose to let him.
That fact that he's been using your home as his legal address doesn't matter; people are evicted from their legal addresses all the time, when they no longer have a right to stay there.
Notices to leave and evictions are fairly straightforward; your court should be able to provide instructions and forms, or you could hire an attorney who does landlord-tenant work to do this for you.
