I second your thoughts. Parents, tell your (adult) children where your papers are! And keep them in order! when my father died it was a free for all. We had to search through literally every scrap of paper he owned. My mother took me to the closet not long ago, pointed to a shoe box and said,"Everything's in there, the funeral arrangements, the wills,etc. I hope ou don't mind that I made your sister executor?" Are you kidding? I'd rather shave my head than be your executor!
And be sure your beneficiaries are up to date. My step-father used to joke that when he died he was going to leave my mother a rich widow. Which might have come to pass if he had changed his beneficiary to MY MOTHER.

Instead, one settlement went to his first wife($100,000!) and another went to the 2nd wife($40,000). Fortunately, the 2nd wife signed her settlement over to mother, but the other one kept hers. That was a bitter pill, believe me.
AS a side note--if you have a family member who is or will be on SSI, be sure you don't leave them assets worth more than $2000. If they inherit a sum of money Medicaid can make them spend down their assets. YOu need to set up a special needs trust to which you can leave an inheritance. We have a 14yo severely mentally handicapped son who will need constant care as long as he lives. He will go on SSI when he turns 18. He's on Medicaid now and we can't afford to lose that--there are a lot of programs that he is eligible for ONLY because he has Medicaid! If he were to inherit, he would lose all that until the assets were spent. We plan to leave his inheritance to his Special Needs Trust, which will dispense funds for the things he needs, like warm winter coat, dental work, summer camp, vacation trips, ice cream treats--you know, all the things that we would provide him if we were around.
