My uncle is 83 and has a caregiver that he is constantly giving money to. He is kindhearted and has a lot of money, but this, I discovered after auditing his bank accounts, has been going on for years to the tune of $30,000 a month. The caregiver claims she never took any money from him other than what he offered to give her to help her out. He says he gave it willingly, but surely this is illegal! This is in Texas.
Usually if a caregiver is from a license Agency, he/she is not allowed to take any money. Unless it is an occasion gift card or $$ that is in a low amount and if that is allowed by the Agency.
Maybe it is time for the Uncle's Power of Attorney to see if he/she can start taking over the finances, such as the bill paying, etc. I remember my elderly Dad was more than happy to get that chore off of his plate :)
