Only about have half the states offer the protection accorded under LLLPs. They are basically Limited Partnerships that have extended limited protections for general partners against vicarious liability. In a LLLP, no general or limited partner is liable for the partnership's obligations which were created solely by another partner's malfeasance.
Certain states, such as Arkansas and Texas, use a different name for these entities such as Registered Limited Liability Partnerships. In Delaware, a statement of qualification must be filed.
Creating a LLLP is much the same as an LLP. An annual report must be filed and fee paid. In addition, the partnership must have as the last words or letters of its name the words 'Limited Liability Limited Partnership', L.L.L.P. or LLLP.
