My question involves business law in the state of: California
I work with a not-for-profit corporation. We signed a contract with an inventor in California to build a prototype of a motor he was working on. He received $300,000 to build the prototype within a specific time frame and he was to complete the project in California. The funds he received were from public donations to the project. After receiving the funds, he left the state and set up his shop elsewhere. He has been playing games and not fulfilling his end of the contract. He now claims his motor is complete almost 2 months after the deadline. At this point we want the money back from him. He has hired an attorney. We don't have one. How could we go about prosecuting him for breach of contract? Could the California Attorney General be involved?
