Piercing the corporate veil
Piercing the corporate veil or lifting the corporate veil is a legal decision to treat the rights or duties of a corporation as the rights or liabilities of its shareholders. Usually a corporation is treated as a separate legal person, which is solely responsible for the debts it incurs and the sole beneficiary of the credit it is owed.
