I'm sorry for you & your mother Villan.
It's not really legal here either (US) that I know of.
My Mother is a very healthy & active 80+ but she is adament about never being put somewhere "out to pature". She doesn't want to become a burden on her children if it ever came to that, though she be welcomed. She has made it known that her house goes to her children & not to used to keep her alive till she's broke. She has said let nature takes it's course & has a DNR (do not recesatate) if anything should happen to her. When someone's lived that long they should have the right to go out as they chose & with the dignity they've grown accustom to.
