BALTIMORE - A mortgage company insured's failure to identify underlying claims on an insurance application constitutes a material misrepresentation, omission or concealment that renders a professional liability insurance policy and a mortgage banker's fidelity bond void, a Maryland federal judge ruled July 15, finding that the insurer is entitled to rescission of both the policy and the bond (Prosperity Mortgage Co. v. Certain Underwriters at Lloyd's London, et al., No. GLR-12-2004, D. Md.; 2013 U.S. Dist. LEXIS 98286).
