N.Y. Banking Law § 221-G
For the purpose of discovering violations of this article or securing information lawfully required by him hereunder, the superintendent may at any time, and as often as may be determined, either personally or by a person duly designated by him, investigate the activities of representatives of licensees and examine the books, accounts, records, and files used in relation to those activities. For that purpose the superintendent and a duly designated representative (i) shall have free access to the offices, books, accounts, papers, records, files, safes and vaults of licensees and their representatives, and (ii) shall have authority to require the attendance of and to examine under oath all persons whose testimony may be required relative to the activities of a representative. The expenses incurred in making any examination pursuant to this section shall be assessed against and paid by the licensee so examined, except that traveling and subsistence expenses so incurred shall be charged against and paid by licensees in such proportions as the superintendent shall deem just and reasonable, and such proportionate charges shall be added to the assessment of the other expenses incurred upon each examination. Upon written notice by the superintendent of the total amount of such assessment, the licensee shall become liable for and shall pay such assessment to the superintendent.
