Dad (93) still has his checkbook & gives money he can't afford to my leeching brother. I am POA, can I take my Dad's checkbook?

Not unless he is incompetent. If he can give money to brother than you don't need to foot half the bill. Tell him that. Its not fair you are giving only to have brother taking, If Dads IL supplies his meals not much more he needs, Utlities shouldn't be much. Does he participate in outings, use a bus to get around? I would leave what he needs in spending money and use the rest for rent and utilities, Then there is nothing for brother.

Have a talk with Dad. Say you know, I could take care of your finances for you. A more realistic budget may allow you to remain financially independent for a longer time. You would still have spending money, and I would always report to you in writing.

Tell your dad you can no longer afford to subsidize his rent.

How do you know that his cognitive skills are intact? Has he had a real workup?

I vote take it away, one way or another. He doesn't have the money. You are subsidizing him. Stop the insanity.

FYI. Here's the harsh part. I eliminated her from the equation, financially. Took me a minute, or a year. But, it was in my Mom's best interest. And the sad part, when my sister asked me for money, because the 'well had gone dry' with my Mom's money, I gave it to her one time. A loan to her, which was never paid back of course. So, done. No more.

So, I'm probably not the best one to give advice. But I'll give you a suggestion. Does he have dementia? If yes, then maybe take the checkbook. I am my mom's POA also, and my sister doesn't always have the best of intentions either. It took me a while-and this may sound controlling and maybe harsh. But I had to do what I had to do to look after my Mom's best interest, financial and otherwise. When my mom was of 'sound' mind it was different, because that was her decision, and she allowed my sister to take financial advantage of her. Charge off on her perfect credit score, etc. My mom told me about some things at that time, but she wouldn't change things. And that was their 'thing' that I stayed out of. And now that she needs so much care? No sister to help out.
