Klein Slowik, a seven-person law firm focused on real estate, construction and related areas of the law, has sued two of its former lawyers and their new firm for allegedly using its resources to set up their own, competing business.

The law firm sued its former lawyers, Michael Farber and Daniel Schneider, and their new firm, Farber Schneider Ferrari, earlier this week in Manhattan Supreme Court, saying the duo used Klein Slowik’s resources to lay the groundwork for their competing firm. The suit said their actions were those of “faithless servants.”
