IAAL, but IANA Wills, Trusts, and Estates L. However, my wife is, so here is some of the knowledge I’ve gleaned off of her over the years:
First of all, I think you have given enough info in your post. Second, good point about the destroying legal tender business.
Now onto business - Scrooge, or for the purposes of this example, let’s call him Bill Gates
, has left a will. The will appoints an executor. This is the person who will carry out the provisions of the will.
Others with more experience can contradict me (feel free), but the gist of it is, the executor has to do what the will says. If the will says, “Take all of my billions of shares of Microsoft stock, sell them, take the money and keep on buying $100 billion worth of McDonald’s Happy Meals until you’ve exhausted all the proceeds, and then bury them all in a landfill,” then that’s what the executor must do. (“Oh, and don’t forget to blow up that big house on the lake while you’re at it.”)
This may seem a thankless task, but no! The executor gets a small percentage of the estate for going to all the trouble - here in NY it’s 5% (which, on Bill’s, I mean Scrooge’s estate, would be a nice chunk of change!)
(Actually the Bill Gates example is completely inapropos - he has already set aside $15 billion for charity, and it is expected he will leave more. Warren Buffet too is expected to leave almost all of his wealth to charity. Nice, no?)
Now to your other point about the money reverting to the government. The Congress, as part of their “tax relief”, has, in their infinite wisdom decided to repeal the estate tax (which they slapped with the moniker, “death tax”), and Bush signed it into law. As of 2010, I believe, it will be gone no more federal estate tax. In 2011, it reappears, as the “tax relief” law has a sunset date, after which the old law springs back into place.
(By the way, Gates and Buffet are totally against this. They think it is wrong in America to have such vast accumulations of unearned wealth pass from generation to generation. Bill’s dad is an outspoken critic of the law.)
So, this means that if Bill conveniently died in 2010, the Federal government would get nothing, although the state estate tax (if applicable in the state) would kick in and take something. (Even with a will.)
But, and this is important, you can bet your bottom dollar that every duck in the pond would be lining up to prove some, any, relationship to Bill, I mean Scrooge. It doesn’t matter if you have to go back, then forward, as long as they’re related. Meaning - if Scrooge’s closest relationship is his great-grandmother’s great-granddaughter (obviously, descending through someone other than Scrooge), that’s good enough, and they will inherit. And with this much money at stake, you can bet that they would find someone.
I could be wrong, but I think this is why they always have a problem digging up dead people. (That and the fact that it’s illegal!) But seriously, for example, when they wanted to unearth, who was it - Billy the Kid?, they had to find his nearest living relative and ask permission. I believe that this could be because that person has inherited the property rights to his corpse. Yuck.
Since this is not exactly my field, feel free to snark on me at will!
