Under New York law, alter ego liability, often referred to as piercing the corporate veil, is a doctrine that permits a court to disregard the corporate form and hold an individual officer, director, or owner liable where that person exercised domination and control over the entity and used that domination and control to commit a fraud or wrong that injured the plaintiff.

In commercial and business litigation, it is common for plaintiffs to assert claims against a business entity for wrongs committed by a corporate entity. Often, plaintiffs will try to “pierce the corporate veil,” or get behind the corporate form, to hold the entity’s officers or members liable for the alleged wrongdoing.
