An executor does not have the authority to make things even between family members, unless it is strictly within the law, according to the Napa Valley Register in "Can mom make son pay debt?"
The article was about an executor who was the child of the deceased and charged with distributing equal shares.
However, one of the siblings had borrowed money from the deceased over the years and never paid any of it back. Unless there is documentation of the loans, there is little chance the executor can take that information into consideration.
There are several problems with what the executor might want to do.
Among them is that loans to children are often more gifts than they are loans. The mother may have “loaned” the money to the sibling, knowing that it would never be paid back. That makes it a gift.
If the loans are undocumented, there is no way to prove they happened short of a court battle. If they were considered loans and not gifts, they could be well outside the statute of limitations.
It can be tempting for executors to want to redress past wrongs. However, they should be careful before doing so.
An estate planning attorney can advise an executor about his or her powers as well as limitations on those powers.
