... declares that a person who deals with any attorney in good faith may accept a written statement signed by that Attorney to the effect that this Power of Attorney has not been revoked as conclusive evidence of that fact.
Doest that article mean, to learn wheter this Power of Attorney is still valid we have a right to request a written notice? İf it doesn't mean like that could you explain me the meaning please.
Thanks in advance.
You have interpreted it correctly. A signed affidavit from the attorney will be accepted as evidence that the Power or Attorney has not been revoked.
