My dad can't sign a check to pay his rent to his apartment and settle his finances. He needs me to help him write checks to pay his bills.
Real Estate Attorney
A power of attorney is a relatively simple document that an attorney should be able to prepare for you quickly. I do not recommend using forms that you find on the internet or in office supply stores as they may not meet the needs of your particular situation. My office is located in Hampstead, NH and is available to assist you. 603-329-5200.
Note: This comment does not create an attorney client relationship. You do not have an attorney until you hire one and pay the requested fee.
Estate Planning Attorney
I would take Ms. Sapeinza's advice....if your father has the capacity (mentally) to do so, he should execute a power of attorney (and also do his other estate planning). His inability to physically sign is not an obstacle to doing this as 1.)someone can sign for him at his direction, 2.) he can sign with a simple mark or x in most situations...but defer to the NH attorney for specific advice.

Elder Law Attorney
If your father has the requesite capacity he can sign a power of attorney. It doesn't have to be a pretty signature, n "X" will do if properly explained. As Attorney Sapienza suggests, do use a form you get online or at a office supply sore. Spend some a little money and have it done right by an experienced elder law attorney. Make sure the POA has an unrestricted gifting power.
