My mother has me and my sister on her checking account. I asked met life to place the proceeds into a money market checking account with our three names on it. My mother is paranoid and fretful all the time now and her doctor has said she cannot live alone.
I'd be sure to have all the met life funds be ONLY and clearly spent on moms direct care or needs. So no checks written ever to you or sissy. If you & sissy are coDPOA for mom, it makes sense to have all on account. But expect if later on mom applies for medicaid, that Medicaid to want every single MMF statement and details on all checks looked at......
If mom does not have a prepaid funeral & burial done, you may want to think about spending some $ from the MMF to pay in full for a NCV funeral/burial. It does need to be within whatever Medicaid limits are for this.
Keep all the met life paperwork in a safe place too as you'll need to provide it to Medicaid if mom eventually runs out of funds.....
