Family member won't move out of my house
Here is my dilemma. My mother, aged 83, came to stay with me last February and has decided she doesn't want to move out. We have no written rental agreement. She has contributed somewhat to expenses (mostly utility bills, but some $ has been given). She is more or less destitute and I felt badly about asking her to leave. She does have her social security. I also have three siblings who SAY they cannot help her.
I need for her to move out because the house needs to have major repairs done on it and my son would like to get it ready to rent out at some point. The house is in my sons' names now, although originally it was in my and ex-husband's name. Ex pays the mortgage still and he also would like her to move out if she can't pay rent (which she has told me she cannot pay).
I have asked her several times to move out and she says she is not going to move out.
What are my options? I live in Hemet, California.
