New York’s largest foreclosure law firm is fighting to overturn a state court requirement that it and other firms submit an affirmation vouching for the accuracy of documents they file for lenders.

Baum P.C. in a foreclosure case arguing that the year-old rule announced by Chief Judge Jonathan Lippman and implemented by Chief Administrative Judge Ann Pfau (NYLJ, Oct. 21, 2010) violates the state Constitution.
