There are few things almost guaranteed to stir up trouble in a family unit like money, and people trying to claim what they think they are owed. Inheritance is a topic that elicits strong emotions and the more family members there are the more likely it is to get complicated. Usually everyone wants to have a piece of the pie.
This is something that one mom and stepmom came up against when she was helping her parents with their estate planning. Her mom and dad had allotted half of their assets to be split between their grandkids, including her stepdaughter. She suggested to them that this wasn't necessary as the teenager would have a sizeable inheritance from her dad's family, but her husband overheard and was not pleased with her advice. Reddit wasn't so sure that when it came down to it, everybody involved deserved a share of the more modest estate.
