N.Y. Real Property Law § 315: Recording books

§ 315. Recording books. Different sets of books must be provided by

the recording officer of each county, for the recording of deeds and

mortgages; in one of which sets he must record all conveyances and other

instruments absolute in their terms, which are not intended as mortgages

or securities in the nature of mortgages, and all executory contracts

for the sale, purchase or exchange of real property, or memoranda

thereof, and all instruments canceling or extending such contracts,

which conveyances, contracts or instruments are delivered to him,

pursuant to law, to be so recorded, and all forms pertaining to

commitments of land to continued agricultural production required to be

so recorded pursuant to section three hundred six of the agriculture and

markets law; and in the other set, such mortgages and securities, and

assignments of rent, delivered to him; excepting that if the recording

is by microphotography or other photographic process, the recording

officer shall not be required to maintain books for such records, but

shall provide such filing equipment as he may deem appropriate. The

recording officer may, in his discretion, record in consecutive order

the instruments received by him, and shall not be required to segregate

mortgages from deeds or other classes of instruments.
