JP Morgan Chase Bank v Shapiro, 2013 NY Slip Op 01357 (1st Dept. 2013)
“The underlying mortgage and note were originally held by Washington Mutual Bank, FA (WAMU). Plaintiff submitted the affidavit of an employee who identified herself as having personal knowledge of, inter alia, plaintiff’s status as successor-in-interest to WAMU and defendant Saadia Shapiro’s default. This was based upon her review of plaintiff’s books and records and its account records regarding Shapiro’s delinquent account (see CPLR 3212[b]).”
Note that affiant was related to successor entity and was not employed when record was generated. This will cut both ways.
