My mom has finally decided to leave my abusive alcoholic drug using "father." She's tried in the past, he's gone to jail (and big surprise he always came back home), she's gotten a restraining order in the past (and had it lifted)... long story short, typical domestic violence story. The thing is, now she is ready to leave him.
Here's were I think there may be a problem. They both own the house, but are not married. It is my understanding CA does not recognize common law marriages, so there would be no "keeping the house in the divorce" seeing as they have never been married. Is there any way we can get him to leave without having to sell the house? I'm thinking/hoping that since there is evidence of abuse (my brother, sisters, neighbors and I could all testify), he has priors and there is a record of his abuse and all the times he's gone to jail for it, we can get a restraining order and he would be forced to leave.
Would that be enough? Or would he still have a right to fight for the house despite not being allowed to come near us? I realize there aren't any lawyers on here but any advice would be greatly appreciated.
