A Pennsylvania Letter of Attorney (Long Form) is a legal document that allows an individual (the principal) to appoint another individual (the attorney-in-fact) to act on their behalf in their personal and business affairs. The principal can grant the attorney-in-fact broad powers to act in the principal's name, or they can limit the power to specific acts and affairs. The Pennsylvania Letter of Attorney (Long Form) is an official, signed and notarized document that must be signed in front of a notary public in order to be valid. There are two different types of Pennsylvania Letter of Attorney (Long Form): General Power of Attorney and Special Power of Attorney. A General Power of Attorney grants the attorney-in-fact broad powers to act on the principal's behalf, while a Special Power of Attorney limits the attorney-in-fact's authority to specific acts and affairs.
