Article 6 - Savings Banks
239-A - Preservation of Books and Records.

§ 239-a. Preservation of books and records. Every savings bank shall
preserve all its records of final entry, including cards used under the
card system and deposit tickets, for a period of at least six years from
the date of making the same or from the date of the last entry thereon;
provided, however, that preservation of photographic reproductions
thereof or records in photographic form shall constitute compliance with
the requirements of this section. Notwithstanding the foregoing, the
superintendent of financial services may prescribe by regulation such
period of time longer or shorter than six years during which all records
kept by saving banks as fiduciary shall be preserved in original form.
