Answer: State Law.
Step-by-step explanation:
This dispute falls under the jurisdiction of state law and so that is what the court will use. This is unless the company established a profit-sharing agreement as per the Uniform Limited Liability Company Act (ULLCA) and the state that they are in is one of the 19 states and District that enacted the UCCLA.
As the company never established a profit agreement principle, this falls under State law which normally calls for the division of profits equally amongst partners.
