Ordered that the order is affirmed, with costs.

In August 2006, the defendant Global Universal Group Ltd. (hereinafter Global) executed a note in the amount of $9,100,000 in favor of Woori America Bank (hereinafter Woori), and delivered to Woori a mortgage on certain real property in Queens to secure repayment of the note. Global allegedly defaulted in May 2011, and thereafter, by failing to pay the monthly sums owed and by failing to pay property taxes and utility expenses. On or about January 12, 2012, Woori commenced this action to foreclose the mortgage by filing a summons and complaint verified by an assistant vice president of Woori, based upon his personal knowledge and his review of records maintained by Woori. The complaint alleged that Global's last payment was received on April 1, 2011.

By notice of motion dated October 24, 2012, Woori moved, inter alia, for summary judgment on the complaint. On November 28, 2012, Woori assigned its interest in the mortgage and note to SDF 19 Linden, LLC (hereinafter SDF 19). In March 2013, Global cross-moved for summary judgment dismissing the complaint. The Supreme Court granted the motion, denied the cross motion, and, thereupon, amended the caption by substituting SDF 19 as the plaintiff.

In a mortgage foreclosure action, a plaintiff has standing where it is the holder or assignee of the underlying note at the time the action is commenced (see Aurora Loan Servs., LLC v Taylor, 25 N.Y.3d 355, 361 [2015]; US Bank N.A. v Cange, 96 A.D.3d 825, 826 [2012]; Bank of N.Y. v Silverberg, 86 A.D.3d 274, 279 [2011]; U.S. Bank, N.A. v Collymore, 68 A.D.3d 752, 753-754 [2009]). Contrary to Global's contention, in the event that a note and mortgage are validly assigned to a third party subsequent to the commencement of a foreclosure action, as was the case here, the assignee can continue an action in the name of the original mortgagee, even in the absence of a formal substitution (see CPLR 1018; Lincoln Sav. Bank, FSB v Wynn, 7 A.D.3d 760 [2004]; Central Fed. Sav. v 405 W. 45th St., 242 A.D.2d 512 [1997]). Moreover, an assignee may, if it chooses, take the steps necessary to effect a formal substitution. Here, upon proof that the mortgage and the underlying debt were assigned by Woori to SDF 19, the Supreme Court providently exercised its discretion by amending the caption to substitute SDF 19 as the plaintiff (see CPLR 1018; Deutsche Bank Trust Co., Ams. v Stathakis, 90 A.D.3d 983, 983 [2011]; Maspeth Fed. Sav. & Loan Assn. v Simon-Erdan, 67 A.D.3d 750, 751 [2009]).

A plaintiff seeking summary judgment in a mortgage foreclosure action establishes its prima facie entitlement to judgment as a matter of law by producing the mortgage and the unpaid note, and evidence of the default, by proof in admissible form (see CPLR 3212 [b]; US Bank N.A. v Madero, 125 A.D.3d 757, 758 [2015]; W & H Equities LLC v Odums, 113 A.D.3d 840, 841 [2014]; Washington Mut. Bank v Schenk, 112 A.D.3d 615, 616 [2013]; Wells Fargo Bank, N.A. v Webster, 61 A.D.3d 856, 856 [2009]). Here, Woori, the original plaintiff, met that burden by producing the relevant documents and the complaint verified by one of its officers based upon that officer's personal knowledge of Woori's records (see CPLR 105 [u]; Kempf v Magida, 37 A.D.3d 763 [2007]; Lebar Constr. Corp. v HRH Constr. Corp., 292 A.D.2d 506, 507 [2002]).

In opposition, Global argued that there was a triable issue of fact as to whether SDF 19 acted with unclean hands in refusing to subsequently close on a bridge loan during the pendency of Woori's motion. Although the bridge loan negotiations were related to the mortgage, since such a loan might have afforded Global an opportunity to refinance, the bridge loan transaction was entirely separate from the underlying mortgage. Accordingly, those two matters were not so inextricably intertwined that factual issues surrounding the contemplated bridge loan warranted the denial of Woori's motion for summary judgment in the foreclosure action (see Imperial Capital Bank v 11-13-15 Old Fulton D, LLC, 88 A.D.3d 652, 654 [2011]; LaSalle Bank N.A. v Kosarovich, 31 A.D.3d 904, 906 [2006]; Fleet Bank v Pine Knoll Corp., 290 A.D.2d 792, 794 [2002]). Therefore, the motion, inter alia, for summary judgment on the complaint was properly granted, as Global failed to raise a triable issue of fact in opposition to Woori's prima facie showing of entitlement to judgment as a matter of law (see Zuckerman v City of New York, 49 N.Y.2d 557 [1980]).

Global's remaining contentions are without merit.
