COLUMBIA, MO. • The state of Missouri has filed criminal charges against a shuttered Georgia company accused of using fake signatures on phony foreclosure documents.

A Boone County grand jury on Friday issued a 136-count criminal indictment alleging forgery against DocX and its former president, Lorraine Brown. The company closed in 2010 amid criticism of mortgage companies signing legal documents not reviewed by its employees in a practice called robo-signing.

Missouri Attorney General Chris Koster said Tuesday that the company falsified 68 notarized deeds on behalf of mortgage lenders. A St. Louis attorney representing DocX did not immediately respond to a request for comment.

The Missouri case comes as the nation's five largest mortgage lenders negotiate a settlement with federal and state officials that could reduce loans for 1.75 million homeowners nationwide.
