I have one now that has just (mostly) wrapped up. Oh, and a half-drama that was inheritance related but not family caused.
First, the latter: Mom's side. Five kids. Grandparents live on farmland in MN and I think rent out the land. Grandmother dies in her 60s, Grandfather lives for 12 more years and then dies in his 80s. Everything is sold. I snagged a Christmas decoration I'd always liked and a bunch of my Grandmother's fabric stash and am happy, and my part is otherwise over except that I as an adult grandchild was a witness (as in signature) to the wholly civil and fair equal division of assets among the five kids. Later find out that there was drama not directly among the kids, but because the financial person who was supposed to be in charge of the liquidation and division of assets helped himself to some first. The only argument among the siblings was whether or not to risk legal fees to get the money back. Two siblings wanted to go for it, three (including my mother) did not. They went after the person, got the money back, and then got the legal fees back. It was amazing. The stolen portion was then divided up equally and distributed.
Second, the former: Dad's side. Four kids. Bro1 Bro2 Sis1 Sis2. Grandparents play blatant favorites among the kids, so that Sis2 (Grandma's fave) feels more special than the rest and yet somehow treated worse than the rest. Bro1 is a mooch and repeatedly borrows money which never is repaid. Bro2 (my dad) hits hard times, borrows some money, pays some back, dies before 60 leaving myself and three younger siblings (very sad). Sis1 and Sis2 have better financial fortunes, but Sis1 stayed local and ended up doing much more day to day care in the end while Sis2 had better things to do with her wealthy husband but "oversaw" from afar.
Grandma and Grandpa get older. Bro1 moves in to
help them live rent-free and waited on and justifies this by sleeping in the house to call 911 for a fall once in three years. Grandpa dies in his 90s. Grandma can't live alone and goes to a retirement community with a subset of her possessions. The rest are sold at auction after Bro1 and Sis2 independently prevent a drama-free and fair division of items. All the money from the auction goes into a Trust that Grandpa set up for Grandma's care, while Grandma's remaining possessions--furniture, jewelry--and small amount of cash remain in a separate estate.
The house and building owned by Grandpa are eventually cleaned out and sold, cleaning out and organizing largely done by Sis1 who was paid a fair and fairly cheap amount to take care of Grandpa's sensitive work documents (lawyer) and do similar in the house to get it ready for the market. Money from house and building sale go into the Trust. Sis2 engages in shenanigans such as buying (and getting reimbursement for) expensive and unnecessary furniture for Grandma's new retirement digs, ordering extra personal companion time (at Grandma's expense) in lieu of actually visiting, stealing all of Grandma's jewelry "for safe keeping", and being an all around pain in the ass.
Grandma dies in her 90s after a few months of stepped up nursing home care, which mercifully cut short both her cognitive decline and the outflow of assets from the trust to the care facility. Grandma's will for her estate and the Trust are carefully poured over for instructions. The Trust allows for extra expenses from the estate to be paid with Trust funds and remaining funds are to be distributed to heirs per stirpes minus any outstanding loans. Grandma's estate is to be divided among the three surviving children, cutting myself and my siblings out entirely. Sis1 and my mom are outraged and Bro1 doesn't care as long as he gets money (which he won't). Sis2 pretends to be outraged, but takes the opportunity to also pretend she's magnanimous by declaring that she only wants a few items (never mind they are jewelry pieces holding almost half the value of the estate) and that my sibs and I should benefit from the estate (subtracted from Sis1 and Bro1's portion, natch).
Grandma's physical assets are divided into four very unequal portions, and there is no cash to speak of for Bro1 (who at almost 70 years of the mooching life is broker than broke and still managed to buy Grandpa's building, but can barely pay the mortgage). At the same time, the Trust is going through the settlement process and Bro1's loans exceed his share, Bro2's loans greatly reduce his share, but Bro2's heirs will also get 1/3 of what should have been Bro1's share. Bro1 decides to submit a multiple five figure bill for "caretaking" in the form of spreading his crap around the house, eating Grandma's food and doing no cleanup, and sleeping on the couch for two years. The rest of us laugh and no payment occurs. Sis 2 is still cranky that Sis1 got paid for legitimate and necessary work and submits a bill for her own personal legal fees as well as for an unnecessary service that we have in writing she said she would do for free. The Trustee rolls over like a trained dog, adds these to Sis2's share, and hands it over.
My mom and Sis1 go ballistic and try to recover justifying documents if not the money itself, but are threatened that there will be no money left for Sis1 or Bro2's shares if they try to fight. Mom and Sis1 take their shares. Mom hands me my 1/4th, while Sis1, who just retired, is going on an accountability rampage up to and including changing the Trustee laws in the state.
Bro1 doesn't talk to anyone else in the family, Sis2 doesn't talk to anyone else in the family, and Sis1 decides to keep Bro2's family because we are not batshit crazy.
I got the couch Sis2 needlessly bought for Grandma, the start of my down payment fund, and an object lesson in treating your children equally.
