Okla. Stat. tit. 54, § 54-1-306: Partner's liability

Partner's liability. (a) Except as otherwise provided in

subsections (b) and (c) of this section, all partners are liable

jointly and severally for all obligations of the partnership unless

otherwise agreed by the claimant or provided by law.

(b) A person admitted as a partner into an existing partnership

is not personally liable for any partnership obligation 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, is solely the obligation of the

partnership. A partner is not personally liable, directly or

indirectly, by way of contribution or otherwise, for such an

obligation solely by reason of being or so acting as a partner.

This subsection applies notwithstanding anything inconsistent in the

partnership agreement that existed immediately before the vote

required to become a limited liability partnership under subsection

(b) of Section 55 of this act.
