So due to various reasons I don’t really care if my entire family gets tied to train tracks and run over tomorrow, but I still think it’s blithely comedic
Now that my dad is entering the Biden stage of his life, my siblings have started to fight over who gets what (By which I mean the shitty furniture in the house; also I got cut off a long time ago lmao 
)
Apparently my brother is now demanding “unpaid rent” (at $3000 a month, over 16 years) from my dad because he lived with him and had to deal with the “mental anguish” and “caretaking responsibilities”.
The kicker is that my dad was always whining year after year about him living in his house and threatening to kick him out time after time (he never did). My brother was always whining about living with the old man too (he has his own house sitting empty that he can move to at any moment). They basically live entirely separately within the house lol.
It also came out that he was also siphoning money out of dad’s account (in addition to half of the pension that he somehow convinced dad to give him). Now my sister is mad and saying she should get the other half.
I found out about all of this after he sent me a five figure “invoice” for “caretaking services”
If your brother wants to get paid for caretaking, that's between him and Medicare/Medicaid, not you or your father's estate. $3000/month is an ambitious figure and I'm sure he'll have a lot of fun trying to get them to pay retroactively. Might be a good time for you or your sister to get Power of Attorney.
I’m confident he’s well aware he’s not getting that kind of money, he does this kind of thing all the time just to rile people up.
Wouldn't be surprised if someone in the family hires a hit on him and no one bats an eye
