The Compromesso or Contratto Preliminare is a binding preliminary contract that legally commits both parties to complete a property sale at a future date, specifying the price, property description, location, and grounds. This agreement creates enforceable legal obligations and allows either party to seek legal enforcement if the other withdraws, making it a far more serious commitment than a simple purchase offer. In our experience at Trevi Elite, buyers should understand this is not a tentative step but a contract with real consequences, typically accompanied by a substantial deposit and leading inevitably to the final deed of sale before a notary.
