Had a terrible problem in the UK with my grandmother, we never got a lasting power of attorney for health, and by the time she needed it it was of course too late. Figured next of kin would be reasonable.

She's been incarcerated in a care home since the start of covid, although rather than one near to where family lived they refused to let us move her. Took 18 months of going through court to get her moved, she has degraded so far she barely remembers me now.

(And of course despite legally being kept in the car home she has to pay for it. Had she broken the law and gone to prison she'd have more freedom and wouldn't have to pay!)

We now have power of attorneys for our parents.
