My husband and I are POA for dad and had it for my late mum.

The POA should be the person who lives close. No way could Sis perform her duties from another country. Is she afraid you are going to get all the money or spend it?

What sparked the Sister's upset off?

Has there been a change in Dad's health or situation she just found out about?

Here in the U.S. the PoA is not obligated legally or otherwise to disclose the paperwork to anyone, not even family.

Hi guys
thanks for your input
It just reasures me and yes I am being drawn into drama
she asked me for a copy of pos and unbelievably my mums OLD will that I have sent as I have nothing to hide
I am now looking after dad who has Alzheimer’s
where is she not been to England since mums funeral in june

She's allowed to have her feelings - but they are irrelevant with respect to your position as POA. It is a legal designation put in place by your father when he was competent to make that choice, and he chose you. She can be upset about it. But if the POA is invoked and dad is no longer competent to make changes - it can't be changed anyway - even if dad wanted to do so. And you aren't saying anything that leads me to believe that he does. Just that she is upset that you have the designation .

Not her business. Not your problem.

Fortunately she lives abroad. Ignore her and refuse to be drawn into any drama.

You’re allowed to have POA and she’s allowed to fume. Why do you need to discuss it at all? I have a sibling who fumes, I go with ignore and delete
