SH and I are arguing about wills. I want him to write one, darnit, because if I die before he does and then he dies before his parents do but he has not spent my 401K, which is not insubstantial because I thought I would never marry and would have to provide for myself until my death at 97 or so because that's when the women in my family die, I want my mother to have it and I will leave the rest to your imagination but if you want to know more, be my facebook friend because that's where I put the Good Stuff. Just leave me a note in the comments.
My mom's dad lived to only 88. His life was tragically cut short by smoking and the bacon grease he put on his toast every morning.
I found this advice at a legal website. Don't say you weren't warned. "I forgot" is not a legal defense.
Provide at Least Nominal Gifts to All Your Children. Make certain that you leave at least something for your children (and your grandchildren, if any of your children are deceased), if you have any such descendants. If you leave nothing for them, a judge could determine at a later date that you forgot to do so, should one of them challenge your Will.
See? Smoking. And guns. Gets you every time.
