I believe wills and estate planning is something most people don't want to talk about but should be a priority.
My in-laws had only one child (my wife) and put everything in her name years before they passed. Home, property, assets, everything.
They trusted her implicitly.
My wife always had her parents best wishes at heart and she is trustworthy.
They lived at home long as possible, her Dad passed at 90. Her Mom five years later wanted to go into a nursing home, unable living at home. The nursing home administrator wanted access to Mom's money, etc however couldn't since it was in wife's name over 5 years. They did get her SS and Medicare paid medical.
Then a certain family member started visiting Mom every day. I suspected something wasn't right so advised wife taking her to a psychiatrist for evaluation. For $75 he determined Mom was incompetent, had dementia and wrote a letter stating that.
I made a copy, placing it on Mom's nursing home nightstand in plain sight.
Wonder of wonders...that certain family member never visited again!

Careful planning is essential and the goal is to carry out their wishes. Lots of times as someone gets old or passes the vultures appear.
We were with Mom when she passed at 97.
The minister was there also, my wife held her Mom's hand saying we love you but it's time for you to move on and once again be with Dad.
At that point Mom smiled and her heart stopped beating.
