(a) A partnership is an association of two or more persons to carry on as co-owners a business for profit and includes, for all purposes of the laws of this state, a limited liability partnership.
(b) But any association formed under any other statute of this state, or any statute adopted by authority, other than the authority of this state, is not a partnership under this chapter, unless such association would have been a partnership in this state prior to the adoption of this chapter; but this chapter shall apply to limited partnerships except insofar as the statutes relating to such partnerships are inconsistent with this chapter.
