Hi, spencer.
What I did with Mom and the bank, one day, when I had her in the car and we were coming back from a dr's appt, we went by the bank. She stayed in the car and the bank officer came out to her with the paperwork for her signature. I know you've said your dad doesn't like going to the dr, but sometime when you have him for an outing, see if this is something he would do.
I know what you mean about balancing accts. Take your time and get a system worked out. You'll do fine.
Hugs,
Barb
