We took them in with the understanding that they could leave once they are back on their feet. As what has been happening, they are freeloading: consumes utilities without chipping in for anything. They started taking care of chickens for cockfighting around the house when we specifically warned them against it because we are living within a residential area. And worse of all, they are swearing at our mother and threatening to burn the house down and harm my younger sister. We really can't take this kind of treatment from them and we want them out of the premises ASAP. We already tried talking to them to no avail. Our uncle explicitly announced that he wouldn't leave and he threatened to slap my younger sister if she keeps on insisting on it. We (my mother, sister, and I) own the house and the land.
What could we possibly do about this?
