La cambiale di matrimonio, also known as The Bill of Marriage or The Marriage Contract, is a comic opera by Gioachino Rossini with a libretto by Gaetano Rossi. Based on a play by Camillo Federici, the production is a farcical story about a couple who undergoes pre-marital counseling with relationship expert who doesn't believe in the traditional concept of marriage. Instead, he feeds them his own plan known as The Marriage Contract, in which couples negotiate their own terms of marriage like any given business deal.
