4:61-2. Allegations of Demand and Refusal; Title

If the action is for a wrongful detainer only, the plaintiff in an action for replevin shall allege a demand and refusal of possession before commencing the action. A plaintiff in replevin who claims possession as a secured creditor shall allege both in the complaint and the motion for the issuance of the writ the existence of the debt and the existence of a security interest, perfected or unperfected, in a chattel in the possession of the debtor. If the title to the goods or chattels of the plaintiff in replevin rests upon the title of a third person or upon a special property, those facts shall be alleged.
