New York Laws
Part 2 - Formation and Construction of Lease Contract
2-A-206 - Offer and Acceptance in Formation of Lease Contract.

(1) Unless otherwise unambiguously indicated by the language or
circumstances, an offer to make a lease contract must be construed as
inviting acceptance in any manner and by any medium reasonable in the
circumstances.
(2) If the beginning of a requested performance is a reasonable mode
of acceptance, an offeror who is not notified of acceptance within a
reasonable time may treat the offer as having lapsed before acceptance.
