Statewide filings of new foreclosures plummeted after Chief Judge Jonathan Lippman on Oct. 20 required attorneys for lenders to submit affirmations attesting to the accuracy of their court submissions, state figures show.

There were 797 residential foreclosure filings during Oct. 18-24, the week of the chief judge’s announcement of the requirement, according to the Office of Court Administration. There has been a precipitous decline since then; only 100 filings were recorded during the week of Dec. 6-12.
