I own a house with a guest house on the property in NEW YORK, my mother has the right to live in the guest house as long as she wants, she is NOT on my deed as a life tenent we do however have a written agreement stating she could stay there, she left last July took her clothes, old coins, jewelry, anything of value and moved in with her boyfriend, she does come back every couple of months for ONE night! Question: My brother who has been treated for suicide and drug addition is coming to visit with a friend, Its my understanding that my mother is going to let him in the house and let him stay there (she will not be there). I know that he will have his drugs with him, (as sure as the sun will be up), What should I do? I have already spoken to him about bringing drugs, If he has them do I have a right to tell him to leave? Or is my mother allowed to have ANYONE stay whenever they want? Hw will be here this Friday so if you can help that would be GREAT!
