Where can I find a POA form?

Mordan, I agree with the other posters, see an Attorney, especially an Elder Law Attorney. When it comes to Power of Attorney and any legal document doing it yourself could backfire.... all it takes is one missing word or misplaced word to cause a serious problem.

Oh, I see you just wanted to know where to find the form. Hoping she is not against it.

My husband will not give a POA to anyone. I am his rep-payee. While this does present problems for me, so far waiting, taking the time to explain, and using gentle persuasion has helped.
Your case is different, and imminent, so you are right to ask for help. Go easy.
Offer her other solutions-sister POA?

sorry - should have been "attacked", not "attached."

Mordan, if your wife is in fact cognizant enough to execute a POA, you should also ask her to sign a Living Will or Advanced Directive so that you have instructions from her on medical care in the event of an emergency.

But you would still be better hiring an estate planning or elder law attorney, especially if there are siblings, adult children, and others who might contest disposition of her assets. You don't want to place yourself in a position of being attached by family alleging undue influence.

You say in your profile she is suffering from Alzheimer/Dementia. Depending on the severity of the disease, she may not be competent to sign a POA.

So sorry to hear that your wife is becoming incapacitated. You might want to consult with an attorney about living wills as well.

Each state is different -- but here's a good source. You will need her to sign a POA before a notary, and you cannot be the witness.
