Quizplus · Accepted Answer

The Uniform Partnership Act (UPA) and the Revised Uniform Partnership Act (RUPA) have been widely adopted across the United States, but not all states have adopted them, and it is not accurate to say that all states except New York have adopted either version. Adoption varies, and some states may have their own partnership laws that differ from or incorporate aspects of the UPA or RUPA.
