A landlord or a lessor may commence a summary proceeding under RPAPL 721. Generally, the entity that owns the property would be named the petitioner. However, proof of ownership is not necessarily a prerequisite to maintaining a proceeding. In one case, a tenant’s request for dismissal was declined where the petitioner’s name was the same as that on the lease. There, the tenant did not deny dealing exclusively with the petitioner, including the negotiation of the lease, with respect to the tenant’s entry into possession, and with respect to payment of rent. The entity that owns the property would normally be the named party petitioner.
