What is the name of your state (only U.S. law)? CA I have been living with my girlfriend for 17 years. she's never worked we have 2 kids together ages 12 and 14 and have a house with both names on title. She made me leave and i was wondering if i would have to pay her anything and what can I do about the house. I want joint custody of the kids. What can I expect when I go to court. Thanks
