A New York Affidavit that Power of Attorney is in Full Force is a document in which an individual acknowledges a power of attorney is in full force and effect. There are two types of New York Affidavits that Power of Attorney is in Full Force: a general affidavit and a special affidavit. A general affidavit is used to confirm the validity of the power of attorney. It is signed by a notary public, who certifies that the document is valid and authentic. It includes the name of the principal and agent, the date of execution, and a description of the power of attorney. A special affidavit is used when the power of attorney is required for a specific purpose, such as the sale of real estate, sale of a vehicle, or medical decision-making. The affidavit includes the same information as the general affidavit, but also includes the specific purpose for which the power of attorney is being used. Both types of affidavits must be signed by the principal and notarized in order to be valid.
