District of Columbia Code Division V. Local Business Affairs § 29-603.06. Partner's liability.

(a) Except as otherwise provided in subsections (b) and (c) of this section, all partners shall be liable jointly and severally for all debts, obligations, or other liabilities of the partnership unless otherwise agreed by the claimant or provided by law.

(b) A person admitted as a partner into an existing partnership shall not be personally liable for any partnership debt, obligation, or other liability incurred before the person's admission as a partner.

(c) An obligation of a partnership incurred while the partnership is a limited liability partnership, whether arising in contract, tort, or otherwise, shall be solely the debt, obligation, or other liability of the partnership. A partner shall not be personally liable, directly or indirectly, by way of contribution or otherwise, for such a debt, obligation, or other liability solely by reason of being or so acting as a partner. This subsection shall apply notwithstanding anything inconsistent in the partnership agreement that existed immediately before the vote required to become a limited liability partnership under § 29-610.01(b).

(d) The failure of a limited liability partnership to observe any formalities relating to the exercise of its powers or management of its business is not a ground for imposing liability on any partner of the partnership for any debt, obligation, or other liability of the partnership.

(e) The cancellation or administrative revocation of a limited liability partnership's statement of qualification does not affect this section's limitation on the liability of a partner for a debt, obligation, or other liability of the partnership incurred while the statement was in effect.
