An affidavit, executed by the attorney-in-fact or agent, setting forth that he has not or had not, at the time of doing any act pursuant to the power of attorney, received actual knowledge or actual notice of revocation or termination of the power of attorney, by death or otherwise, or notice of any facts indicating the same, shall, in the absence of fraud, be conclusive proof of the nonrevocation or nontermination of the power at such time. If the exercise of the power requires execution and delivery of any instrument which is recordable under the laws of this state, such affidavit when authenticated for record in the manner prescribed by law shall likewise be recordable.3. No report or listing, either official or otherwise, of "missing" or "missing in action", as such words are used in military parlance, shall constitute or be interpreted as constituting actual knowledge or actual notice of the death of such principal or notice of any facts indicating the same, or shall operate to revoke the agency.4. This section shall not be construed so as to alter or affect any provision for revocation or termination contained in such power of attorney.5. If any provision of this section or the application thereof to any person or circumstance be held invalid, such invalidity shall not affect any other provision or application of the section which can be given effect without the invalid provision or application, and to this end the provisions of this section are declared to be severable.N.Y.
