A New York court has allowed Chadbourne & Parke to proceed with a fraud claim against the business manager of a former client who promised his boss’s legal bill would be paid out of proceeds from the sales of an Upper East Side townhouse and a Princeton, N.J., estate.

Most legal fee claims are based on breach-of-contract theories, but Manhattan Supreme Court Justice Debra A. James said Chadbourne had adequately shown it had been injured by misrepresentations and false statements collateral to the contract.
