On my side of the family, I believe every one of us would split it regardless.
On my wife’s side they’d keep it quiet and then try and sue if they found out. I’d never seen more disgust or hatred until my wife’s father died. He had left a will and didn’t split evenly which caused a lot of hatred. My wife just told them to keep it all as it was destroying the entire family. Her brother, who was left “in charge” followed the will to the letter. He got the most, which I could see why, then the older brother got the next most, both girls got the least with my wife the most least. The brothers don’t talk to any of the siblings. They won’t talk to my wife because she tried to remain “friends” with them all. About the only person she does talk to is her sister and she’s as evil as anyone I’ve ever met. So much so that she’s banned, barred, or whatever term you want to use from even setting foot in my house.
Just share it and move on.
I’ve told my parents if I’m in their will, just exclude me out of it. I’d even pay the lawyers fee to have it done. I don’t “think” anyone in my family would come to the mess my wife’s family came too, but don’t want to take the chance. The difference in my side and hers, is all of us are “successful” for the most part and needing or wanting nothing. Not the same on the wife’s side. They planned their inheritance before their parents were even thought of being gone. I mean so much so that that was always the topic at Christmas time. I hadn’t been to any of their gatherings for many many years even before her Mom passed then her Father.
