Anthony Maglica and Claire Halasz, as boyfriend and girlfriend, lived together, held themselves out as a mar ried couple, and acted as companions toward each other. In fact, Claire changed her last name to "Maglica," even though the couple never married. Together, the couple worked in a business owned solely by Anthony, although Claire participated in a substantial part of the work. The company, Mag Instrument, was incorporated in 1974, and all shares went to Anthony. However, both Anthony and Claire were paid equal salaries. After the company began manufacturing flashlights, the company grew rapidly, now exceeding hundreds of millions of dollars in net worth. In 1992, Claire and Anthony separated, and subsequently Claire filed suit against Anthony for breach of contract and claimed damages under a theory of quasi-contract. No contract existed between Anthony and Claire. Does Claire have any remedy under a theory of quasi-contract? If so, what must she prove?
