The plaintiff establishes standing by showing that it had either a written assignment or physical possession of the underlying note and mortgage prior to commencement. A conclusory statement in an affidavit will not suffice when standing is raised as a defense. Here, the affiant's bare claim that plaintiff "has been in continuous possession of the Note and Mortgage prior to referring the Loan to be foreclosed" is not sufficient to establish standing.
