Other thread about estate planning reminded me of this.
I have been going through this and seeing others go through this several times in the last couple years. For the most part, your kids don't want all the crap you've stored. Also, all that stuff you think is worth something...it probably isn't any more.
Listen, when you die, your kids/grandkids are going to be upset and mourning (God willing). Unfortunately, they also might have just finished painstakingly nursing you through a months long if not years long terminal illness. AND NOW...they have to get rid of 3 decades of National Geographic you saved, 8 rooms of "antique" furntiture, and boxes upon boxes of china and glassware that have been packed away since the Carter administration.
It absolutely sucks. It's emotional, but it's also damn hard work, very expensive, and delays the ability to settle your estate. Frankly, its a shitty thing to do to your kids in what will already be a shitty time.
1. Ask your kids what they want. With the exception of some extremely important family heirlooms like a great grandfather's civil war medal or something that you might insist they keep, if they don't specifically want it, trash it. Even if it's important to you. Nobody wants autographs of the guy that played the uncle on the Patty Duke Show, even if it was a huge deal to you when you met him. They never met your grandmother, what do you want them to do with her wedding dress...are they supposed to store it for years indefinite?
There are plenty of things that have great sentimental value to
you, and that's why you've kept them. It will be painful to throw them out, for sure. But if you don't, all you are doing is transferring that pain to your kids, forcing them to feel terrible about getting rid of (or having to make room for) something that "obviously meant so much to mom" shortly after you've kicked the bucket.
2. That stuff that you're sure is valuable? Unless you've had it appraised in the last few years...it's probably not. No, don't throw out a Mickey Mantle rookie card, but older people from the pre-Ebay era are convinced that tons and tons of stuff is "valuable", and most of it isn't. It probably was at one time. If you needed to find the gravy boat to complete a 1940's set of Sears dishware in 1989, that might mean scouring estate and garage sales for years, and you might well have been willing to pay $100 once you found it. Now, you can find hundreds of them shipped free from from all over the world, and they cost like $9.
Most of that old crap isn't really worth the hassle it takes to liquidate it. I went through this with my mother and the "depression glass" she lugged from house to house for 60 years. I had boxes of the stuff...and when I took it to a dealer, they bought one candlestick for $10. I went straight next door and dropped it off at Goodwill.
Here's the tip I was told...if it wasn't really valuable in it's time, it's probably not very valuable today. If you've got Swarovsky cristal or Tiffany in the attic...that's probably well worth something today...but if middle-class ass folks like my parents could afford it in 1960, it's not worth shit today for the most part.
If you really think you've got something valuable, get it appraised, and unless your kids are specifically opposed, sell it now. You're the one who used to be into classic fishing lure collecting, you know what you've got, so you sell it. Otherwise you're turning it over to your kids to learn how they are supposed to price and sell antique fishing lures. The vague "that is supposed to be worth something" applied to half your household just leads to way more crap, and way more work to get rid of it.
3. Nobody is going to want your old furniture. Unless you know for a fact you have some special turn of the (last) century piece, make piece with the fact that it's functionally worthless. Nobody wants a china cabinet any more. If you paid $1500 for a big china cabinet in 1965, it is currently worth -$100 that your kids will pay a hauler to take away. Same for fancy dining tables, buffets, big chandelliers. Most of that stuff they will not be able to actually, literally give away for free. There is a good chance that "Amvets will pick it up" is not at all true either.
Now, I'm not in this case saying you should get rid of the furniture you are using on a daily basis, and live your last 20 years out in an empty room. But when you downsize, or move into active adult housing or whatever...don't store that stuff. And give your kids permission, if not instruction, to just get rid of it in the easiest and cheapest manner possible.

R: If it's not something you currently use, and it's not something your kids specifically want, don't burden them with having to get rid of it all when you're dead.
