The Massachusetts Appeals Court has joined the U.S. Court of Appeals for the First Circuit in upholding the Mortgage Electronic Registration Systems, Inc. ("MERS") business model under Massachusetts law. Explicitly referencing the First Circuit's decision in Culhane v. Aurora Loan Services of Nebraska, 708 F.3d 282 (1st Cir. 2013), the Appeals Court in Sullivan v. Kondaur Capital Corp., 85 Mass.App.Ct. 202 (2014), held that mortgagors have standing to challenge an assignment of their mortgages, but only to the extent that such assignment is void, not merely voidable. Further, the Appeals Court found that the MERS system of mortgage assignments fully comports with Massachusetts law.
