Cant teach an old dog new tricks. His wife paid the bills since they were together (50years+). He still knows lots of stuff he grew up doing. Like golf. He can tell you won what game the week before and by how many strokes (he's a golfer). But trying to teach him bills and how to write a check as online was way over his paygrade, was impossible. The family found it easier to just pay his bills for him. So all the bills get mailed to his daughters address.
He still drives and has his license. IDK about voting, never asked.
I had always managed the bills with my wife. I paid everything on or before the due dates to avoid late fees and interest.
I was then deployed 3 times to Saudi Arabia, and my wife had to take over the finances during my absence.
Each time I returned, it took me a month to get all the bills back on track. She would wait until my payday -- twice a month -- to do the bills. But, there were bills due between paydays that were late when she got around to paying them. She always had excuses like not enough in one paycheck to pay all that was due, yet I never had that problem because I would pay some bills early out of the previous check. 1/2 a month ahead versus 1/2 a month behind.
It became so frustrating trying to sort out her messes, I finally told her she was in charge of the bills from then on. Rather than 2 systems of paying bills, we would just have one. My hope was that she'd learn as we went there's a better way than only paying bills on payday.
After a year of increasing late fees and interest, I finally had to take the checkbook back. By then, I had online bill pay with USAA, so I could manage the money from anywhere that I had Internet access. In fact, I set up all the bills I could on auto-pay, so none of the due dates were missed.
With today's environment, it's simple to setup auto-pay from each company -- gas, electric, water, phone, mortgage, credit card, auto insurance, etc, etc -- and even to request different days in a month to pay so they aren't all overlapping. Your daughter could easily set that up for him and let him manage the money that way. She'd still be able to help if there were any problems.
Just saying, he really doesn't need to know how to write a check or to set up online payments. Once it's established, it's pretty much on auto pilot.
Now, if he's losing money to scammers or online gambling sites, that's another conversation. There are plenty of competent people out there with those problems.
