A non-disclosure agreement is a legally binding contract that establishes a confidential relationship between two or more parties and protects the information they share from disclosure to outsiders. The party or parties signing the agreement agree that sensitive information they may obtain will not be made available to any others. Non-disclosure agreements are common for businesses entering into negotiations with other businesses.
