Courts evaluate the claim under a totality of the circumstances test that weighs factors including undercapitalization, failure to observe corporate formalities, commingling of funds, and use of the entity as a mere facade.

An equitable doctrine that permits a court to disregard the separate legal existence of a corporation or limited liability company. The doctrine imposes personal liability on owners when the entity functions as their mere instrumentality and adherence to the corporate form would sanction fraud or promote injustice.
