You have to give him a 30 day notice (unless your states law says otherwise)
Notice to quit Free Form
You need to check with your district court or somebody for your state law on if you can just hand him the notice or if you have to also mail him a certified copy and what all laws they will require for it to be legal. Like does it have to be reason for eviction included.
If he doesn't leave within the time then you need to go threw the magistrate.
Since it is family have you warned him that you wanted him to comply to your rules?
Evicting can cause hard feelings that may be hard to repair.
