New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 42-7

A landlord or lessor to whom 1 year's rent in arrear is due, and who shall have the right to re-enter the demised premises for nonpayment thereof, may without a formal demand or re-entry, institute an action for the possession of such premises. If the summons in the action cannot be served in the usual manner, the landlord or lessor may affix the same upon the demised premises in a conspicuous place thereon, which affixing shall be deemed legal service thereof. The service or affixing shall take the place of a demand and re-entry.
