My childhood was good, but a little bit chaotic because Dad had some good jobs, some bad jobs, periods of unemployment, etc. I was a teenager when Mom taught me the rules she followed when things went south: What bills to pay first (rent!), always have food in the house (my life is very different now, but when I bought my first home I got a deep freezer and it's well stocked from sales to this day), fill the car with gas when the money is still there, and take out cash and keep it with you. "Everything else is extra," she would say. She was a good manager that way. We never worried about losing our home or not having dinner, even if Dad was out of work.
She passed in 2017 and now I'm learning, especially as his cognitive abilities go, that part of the reason she was so good with money is that he is absolutely terrible with it! I'm realizing that she made him think he was in charge but was actually running everything, and now he wants me to be that person. He won't even keep track of what he's spending — he wants me to do that (how do I do that? I don't know what he's spending). He also gets upset if I criticize his spending because I'm his daughter and it's HIS MONEY.
He has some money from selling their house, as well as a pension and social security and it's enough for years, IF he doesn't spend it all on stupid crap. It's like he's never had to budget because she would literally hand him money to go to the store and that was all he had to spend. He won't allow me that level of oversight and yet he's also spending like there's no tomorrow. It's all just so frustrating and I worry he's going to end up blowing all the house money and then having no where to go.
I don't know if it's cognitive decline or just him being terrible with money. Or both?
I also put all her bills on automatic debit and stopped the various companies even sending paper statements. What she can't see can't confuse her. I do have POAs but they're not currently activated so I do these things with her permission, maybe some of it will work for you.
Accountability worked for my in-laws who were two ridiculous immature brats when it came to money. My husband set them an appointment with our Christian budget guy (not Dave R.) whose incredibly gifted in this area and whose software is patented. Monthly meetings were held (in person or over phone) to go over their budget = accountability. It worked like a charm. He is a very likable, fun, warm, not judgey guy whom clients really look forward to speaking with each session. There’s no condemnation. Just kind guidance and wisdom.
Good luck!
"I am caring for my father with age-related decline, alzheimer's / dementia, cancer, hearing loss, and mobility problems."
So, assuming he has a medical diagnosis of dementia/ALZ. This plus his history of being a bad money manager = make things simple for the both of you.
Hopefully you are his legal FPoA. If so, make sure he has no direct access to funds. Instead, give him a re-fillable charge card. Fill it weekly or monthly and tell him when it's empty he has to wait for the next fill period to get more. Tell him a therapeutic fib that this is what the financial planner recommended so to protect him from theft and to make sure his money lasts.
If you are not his FPoA (or no one is), then this should be created if at all possible. If he refuses to assign a FPoA, then this is a whole other issue -- so come back here for different advice.
How old is your Dad?
