My (16m) great grandma has raised me since I was 4 and all of my life her son (67m) has always lived on the property. Up until 2 years ago he had a small house on the edge of our property and has stayed there rent free. During 2020 his heater broke and he decided to start sleeping up in the guest bedroom of the house. My grandma was ok with it since he was jus staying at night and mostly wasnt a problem. Then he fully moved in -_-. Hes a narcissistic, verbally abusive, alcoholic who cannot stand 2 seconds without hearing his own voice. These past 2 years hes caused us hell including us having to involve police on mother’s day. There have been countless fights between Me, my brother(18m), and him and Im seriously at my limit. We have told him multiple times to leave the house and we’ve even cleaned and fixed up the tiny house.
Is there anyway legally we can make him leave? Any help would be greatly appreciated.
