Kasowitz Benson Torres was named a defendant in a summons in New York state court Wednesday by a real estate investment client seeking at least $100 million in relief. The Am Law 200 firm and a former partner were allegedly acting in the interest of parties adverse to the client in a real estate development project.

Kasowitz Benson and partner Douglas Heitner are accused of acting against the interests of client 111 West 57th Investment and affiliated entities throughout the financing of a real estate development project for the benefit of the firm’s longtime clients, including sponsors, managers and developers involved in the project.
