Apologies if this isn't the right group, I couldn't find one for legal questions!
My mum is selling the family home next week, and wants to give a large sum of money to my brother and I to be used as deposits for our first homes. My brother is not very financially capable, and has a partner who is even worse. They both have a small amount of debt from living in a flat that neither can afford, he is planning to pay off both of their credit cards with the inheritance before using the rest for buying a home.
My mum wants a contract drawn up to specify what money belongs to who in the event that they separate and sell the home. His girlfriend won't be putting any money into the deposit, and will be making smaller repayments than him. What would your suggestions be on what's fair for her to legally own if they separate? If it was left to my brother, he'd probably give her half. If it was left to my mum, she'd give her nothing.
Any advice would be really appreciated, my mum is just worried that the money she gives him will end up going to his girlfriend if they break up (who as you may be able to tell, she doesn't like very much!)
