CPLR § 2105

CPLR § 2105 Certification by attorney

HSBC Bank USA, N.A. v Valentin, 2010 NY Slip Op 03413 (App. Div., 2010)

Contrary to the Supreme Court's decision, the limited power of attorney
submitted by the plaintiff was not invalid because it was not certified
in accordance with CPLR 2105. CPLR 2105 provides, in part, that "where a
certified copy of a paper is required by law, an attorney admitted to
practice in the courts of the state may certify that it has been
compared by him with the original and found to be a true and complete
copy" (CPLR 2105). The copy of the limited power of attorney was duly
certified by the office of the County Administrator, which made further
certification by an attorney unnecessary (see CPLR 2105).

The bold is mine.
