Having a conversation over Xmas with family members and they asked if my other half has done a will. We have 3 kids and his house in his name on mortgage but he said if anything happened to him in to sell the house as it's mostly paid off and get the money. But if he hasn't done a will is it possible his other family could go for the the money? What would happen to us and the kids? We don't believe in marriage a s never crossed my mind but I'm unsure of what really would happen of someone happens to him? God forbid. Thank you
