What rights would my ex have to my house?
Question Details: He is living in his vehicle with very little income and no where else to go. He expects me to let him move back in here because the mortgage is still in his name and the title is in both our names. I pay mortgage and all bills.
If the title is in both your names, it is NOT your house: it belongs to both of you. Being on the title, he is a co- or joint owner with you, and has just as much right to use and occupy the home as you do. He can return to it: one owner has no legal right to keep another owner out of the home.
You may need to sell the home, give him his share of the proceeds (as one of the two owners, he's entitled to half the equity) and move to a new home so you don't need to live together. If you want to sell but he, as co-owner refuses, there is a kind of legal action (lawsuit), traditionally called an action "for partition," which you can bring to force the sale; if it comes to that, consult with a real estate attorney.
