My parents bought a mobile home for me and my son. The title includes my name and my ex-fiance’s name. We had a verbal agreement with my parents to pay them back the $16,000 they used to buy the trailer. Now my ex refuses to leave the home and says he doesn’t have to pay my parents back any money and that he’s going to sell my home and take half of the money. My question is “Is a verbal agreement a legal binding contract?”
