Good day. My mother and my wife does not always see eye to eye. We let my mother stay for free in house for years now which I bought from her and my stepdad before he passed away a few years back. But my mother started a while back claiming she going to sui me and my wife to pay her the rent money to stay somewhere else. Bassically she stating that she thinking of moving to another property and then me and my wife will have to pay that rent money for her to stay there. Is there any legal grounds for my mother to do so? Thank you
