We are writing our wills and husband wants some money to go to his nephew. We have our own son and I don't think we will ever have enough money for him to have a super comfortable life (we're pretty solidly middle class). I could understand giving nephew money if we were loaded, but it seems unfair to our son to be giving his inheritance to his cousin (whose parents are in fact wealthier than we are). Kids are both under 3 so it's not like he has a particular bond with nephew.
He says it's a nice thing to do - should I argue for our son or am I being over the top & this is a normal family dynamic (it wouldn't be that much money either way).
