That is a special case and I agree that in that case authorization is needed since older people can be especially vulnerable to evil relatives.

How about, one is allowed to go to some authority or doctor, 3 times at the space of 10 days, and express their desire. They can always change their mind. At the end of their 3 visits they are given a prescription. This is just an example, there can be other ways.

Edit: to clarify, 3 visits, 10 days apart is 30 days. And, the person has to do themselves so obviously need to be healthy and the person receiving the affidavit/declaration can notice if there are any mental health concerns. Make it 6 visits for total of min 60 days. As long as there is a good and relatively easy process I’m good.
