The law of "shadow directors" means that a person who effectively controls a board of a company, even though that person is not a director, may find himself being legally classified as a director of the company. That carries with it the threat of legal liability for the company's insolvent trading debts in the event that the company goes into liquidation.

Section 502(e)(1)(B) of the Bankruptcy Code allows debtors to seek disallowance of certain types of contingent claims to avoid being twice liable on a single obligation. It has the added benefits of facilitating debtors’ efficient exit from bankruptcy and ensuring that unsecured creditors are paid in a timely fashion. Debtors commonly seek Section 502(e)(1)(B) relief for claims involving environmental remediations or tort lawsuits, for example personal injury actions.
