Even technical errors in mortgage and foreclosure documents can invalidate the foreclosure and subsequent sale of a condominium unit, according to the Massachusetts Housing Court. Following foreclosure, and purchase at the foreclosure sale by the foreclosing bank, the former owner asserted that erroneous references in the foreclosure documentation for the unit invalidated the foreclosure and left her with the superior right of possession. The Housing Court, J. Muirhead, agreed and invalidated the foreclosure. East West Bank v. Chung, Lawyers Weekly No. 17-001-13.
