We are thinking of lending a significant sum to our son who is trying to buy a house with his partner, to whom he is not married. Her parents will give an equivalent amount. They currently have a child and are thinking of having another .
Our concerns are that we don't feel the relationship is at all good . In the event that they split, I imagine she will be given the house as she will have custody of their child, leaving our son homeless. I really have no idea what the situation would then be . We don't want to give them the money unless it is ring fenced in the event of a split so that he has a right to take the money back from the sale of the house.
Has anyone got any advice?
