The ULC approved the original version of the Uniform Limited Partnership Act in 1916 (ULPA 1916). ULPA 1916 underwent multiple revisions, including one in 1976, which was amended in 1985 (commonly referred to as the Revised Uniform Limited Partnership Act or RULPA). The current version was approved in 2001 and last amended in 2013 (commonly referred to as ULPA 2001). The ULC refers to each ULPA version as "ULPA [YEAR]," noting the year the NCCUSL approved it.
Each state can decide whether to:
Adopt the uniform language of ULPA 2001.
Depart from the uniform language and enact nonuniform provisions to their state partnership law.
Most states adopted RULPA, and currently 25 states and the District of Columbia have replaced RULPA with some form of ULPA 2001 (see ULC: Enactment Map).
ULPA 2001 is a stand-alone statute, unlike its predecessor RULPA, which rested on and linked to the original general partnership act or the Revised Uniform Partnership Act (RUPA), as applicable. If an issue is not covered in RULPA's provisions, the RUPA will govern. For a comparison of ULPA 2001 to RULPA, see UCL: Uniform Limited Partnership Act, p. 4.
