Notice to Principal, Generally
The Notice to Principal is a document that describes the broad authority being given to the agent by the power of attorney. It ensures that the principal is aware of scope of power and authority being granted to the agent.

With the exception of those limited strictly to health care or to commercial transactions, all powers of attorney created in Pennsylvania after April 12, 2000 must have a signed Notice to Principal, printed in capital letters and placed at the beginning of the document.

A power of attorney is not invalid without the Notice to Principal. However, if anyone challenges the agent's actions or authority under that power of attorney, the agent has the burden of proving that those actions were proper.  This places the agent at personal risk for each action performed under a power of attorney that does not have a notice and may discourage someone from accepting the role.
