I always thought my mom and stepdad would be well off financially in retirement because they both had good jobs that paid well. But it turned out to be the opposite. My stepdad has always been a narcissist and chronic liar, sadly; he always gave the impression that he made a lot of money, invested, and was living below his means. Fast forward to a few years ago, when I took over everything with POA due to dementia diagnosis for both of them, and the picture was bleak. My late grandmother's houses being put up for auction by the counties due to non-payment of property tax, their residence going into foreclosure for non-payment of the mortgage (only $700 left on principal!), credit cards maxed out and no payments, cable disconnected, water and electric being threatened with disconnection, cars' registration expired, property tax overdue, negative bank account balances, scam transactions every week in the accounts, overdue student loan from decades prior, embezzled my late grandmother's estate and were being sued by my aunts and uncles, no retirement accounts… the list goes on.
Luckily they had good social security and pension payments, and had a little bit of money in a whole life insurance plan that they didn't need, so by cutting off access to everything, cashing out the insurance plan, and using the monthly income responsibly, I was able to get everything but the student loan paid off in 18 months, and the student loan is now on automatic payments. I've been able to get them 24/7 in-home care, and while I live halfway across the country from them, I have local siblings that see them every week to take care of medications and groceries.
I guess the lesson I would like to share, is to be vigilant and keep trying. Things are not always as good as they seem from the outside. Try to catch them in a good mood, on an agreeable day, and get them to sign a POA "just in case." If they have ever used an attorney for something, you might be able to get the attorney to notarize and give them comfort that there's a third-party involved. This is how I was able to get it done with my mom and stepdad.
