Not sure if this is the right place to post but husbands dad lent us £200k for a house a couple of years ago that is a second charge. He’s not asking for us to pay it back only in the instance that me and husband seperate/divorce and we would give the money back upon selling the house. He has told my husband that he doesn’t expect the money back and just wants us to have a nice house. However as he hasn’t gifted us the money and if he were to pass what would happen with the second charge? Would we have to pay inheritance tax on it? I have suggested to husband that if FIL genuinely wants us to have the money is he not better off gifting the money to us now in the hope that he’s still around in 7 years time? I’m not sure how it would all work
