trying to not give too much away but this happened in my family. a relative who has quite severe autism and has been on benefits for something like 30 years (they are in their 60s) is not being given any money by their parents. the parents willed all their physical assets to their other child (with special clauses that the person should still be able to utilise them if they wish) and put any money they would have gotten into a trust that pays out monthly. the reasoning for this in that the person in question is unable to gauge the worth of money, and because they are constantly getting suckered into niche religious groups that want tithes (until they tire of their mannerisms and throw them out).

while it does sound ableist to say, i do really think this is for their own good. it falls on the rest of the family to look out for them now and we do try. both children did agree to this arrangement by the way.
