Elder account holder, possible incapacity

If I'm not in the right forum, please let me know.
We have an older account holder (102!) who has a substantial amount of money. Her son, who managed their affairs, recently died. He had told me that physically she was doing well but that she was very forgetful (no surprise at her age, but she had done remarkably well until recently). I have known both of them personally for a number of years, not just as bank customers, so I'm quite sure he was correct in what he said. I got a call today from the lady's broker/friend who said she had asked him to help her with her account, as she was having trouble understanding it and keeping it up. I'm not sure what to do--obviously, I wouldn't give him access to her account, but with her probable lack of understanding/capacity, I don't feel like I can call her and ask her what she wants, and there are no other family members so she can't rely on someone else to do this for her. What is the best course of action here?

Without legal council and/or a court appointed guardian or POA, there really isn't much you can (or should) do. At least, that's my opinion.

Thanks.

I agree with burkemi. Let him apply through the courts.

Thanks. Tough situation. Living to be 102 isn't all it's cracked up to be

I agree that you can't simply grant the broker access. However, you might reach out to adult protective services in your jurisdiction and ask them to intervene. You would explain that while you do not suspect abuse or exploitation, you do suspect that your 102 year old customer is unable to handle her own finances, and lacks people in her sphere of influence to assume responsibility for her affairs should she lose capacity.
