HRS §490:2A-204
How a lease agreement can be made
A lease can be formed in any way that shows both sides agree, even by their actions. It can be valid even if the exact time of agreement is unknown or some terms are missing, as long as they intended a lease and a fair remedy is possible.

The statute, as written — Formation in general
(a) A lease contract may be made in any manner sufficient to show agreement, including conduct by both parties which recognizes the existence of a lease contract. (b) An agreement sufficient to constitute a lease contract may be found although the moment of its making is undetermined. (c) Although one or more terms are left open, a lease contract does not fail for indefiniteness if the parties have intended to make a lease contract and there is a reasonably certain basis for giving an appropriate remedy.
