Maybe a difference in legal stuff between Canada and USA. When DM got a bit gone (and only a week before she died), I took the POA the doc/lawyer gave me to the bank. I wanted to pay her bills. The lawyer who drafted the POA told her that it was good enough that I could "take it all in cash and give it away on the street". Not so, the bank wanted me to prove it in a court.
I had a bit of a discussion with the bank manager until a person I knew (think teller) told him "he just wants to pay HER bills". Got better, I took bills from her mail box and paid them, one was for electricity for her neighbor across the street. The bank missed that one. So did I. She liked the couple so I never mentioned it to them. I realize I should have, but the beneficiaries would have laughed themselves silly.
I'm not crazy. Honest, the judge had me tested.
