It's something family, especially should do for each other.
NOT having POA in place is certainly more trouble than having it when the time comes it's needed.
Being someone's executor can involve a bit of work, but unless the estate is super complex it's not really too bad.
As executor there are all sorts of legal protections in place for you anyway.
'Been POA/executor for two people who are now deceased... It wasn't that big of a deal.
Wills:
I asked a friend to take me out of his will as executor because of a chit show of complications. He is dyslexic and I would have to follow his notes. He was also fixated on a financial issue ten years old and there were no records. An outsider created so much havoc in the family that communicating was like dealing with Trump.
Executors can be sued and insurance expensive, if you can get it. If there is a hint of anything wrong, the insurers decline.
My M-I-L's will took three years to settle because my B-I-L wanted to take over the estate, particularly the family home. However, he didn't want to own it.
He was deep in debt and if he inherited anything his creditors could seize it. Instead, he wanted to have use of the house for as long as he wanted, which could have been 20 to 30 years. The executor would have to baby sit the estate until then. In the end the house had to be sold to pay the legal fees and had his own challenge fees to pay on top of that. There were no winners.
POAs
POAs come to an end when the person dies and then the executor takes over. My concern would be heirs complaining that the heath care or financial diligence were poorly managed.
One of the worst problems is dementia. The person can live ten years, requiring more care each year. Pulling a plug is difficult both emotionally and legally.
There can be a problem if there are separate POAs for health and finances. One has a duty to preserve dignity of life and the other the preservation of finances. Wearing both hats makes it an internal conflict.
Good homes are incredibly expensive and less expensive ones incredibly problematic.
You can only guess what might happen. My father had Lewy body dementia and was in a home. Then they suspected he had developed cancer and was to go for tests, adding to the concerns. The day before the tests he had a fatal heart attack.
Obviously one would want to know all the details of finances and expectations.
