Maggie Karchmer represents U.S. and European insurers in coverage disputes and monitoring matters under a wide range of insurance policies, including public and private directors and officers, cyber, media and technology, professional liability, and employment practices liability. She also defends lawyers and other professionals against professional liability claims.

Maggie litigates in federal and state courts across the country, including in the Fourth, Sixth, and D.C. Circuits. She has won favorable rulings for insurer clients at every stage of litigation—from motions to dismiss and summary judgment through appeal. Her experience covers the full range of issues that arise in liability coverage disputes, including related claims, the scope of insuring agreements and policy exclusions, notice requirements, and choice-of-law questions. Among other significant victories, she persuaded the Fourth Circuit to reverse a declaratory judgment allowing an insured to tap two $100 million directors and officers liability insurance towers for related matters.
