In the absence of express statutory guidance, most American courts have held that LLC members are subject to the same common law alter ego piercing theories as corporate shareholders. However, it is more difficult to pierce the LLC veil because LLCs do not have many formalities to maintain. As long as the LLC and the members do not commingle funds, it is difficult to pierce the LLC veil. Membership interests in LLCs and partnership interests are also afforded a significant level of protection through the charging order mechanism. The charging order limits the creditor of a debtor-partner or a debtor-member to the debtor's share of distributions, without conferring on the creditor any voting or management rights.
