The new rule, released in a statement by the New York state Unified Court System, is effective immediately.

Chief Judge Jonathan Lippman introduced the requirement in response to disclosures of deficiencies in residential foreclosure filings nationwide, including notarization and “robo-signing” and affidavits that falsely state the signer has knowledge of the facts, the statement said.

“We cannot allow the courts in New York State to stand by idly and be party to what we now know is a deeply flawed process, especially when that process involves basic human needs — such as a family home — during this period of economic crisis,” Lippman said in the statement.
