Under the state's statute of frauds, which can be read here, an oral agreement for a lease of not more than one year in duration is enforceable. We appear to now be past the date that the original lease term ended, so a court could potentially find that the oral promise constituted renewal or that renewal occurred by virtue of part performance. Also, it could be that the lease provides that the renewal is for a year even in the absence of the formality of a signed agreement.

Any informed answer to this question requires a review of the lease agreement, and also of the terms of the exchange between the landlord and tenant about renewal.
