An NDA refers to a legal benefit and refers to the same document as the California Confidentiality Agreement (CA). This document protects your company`s most valuable secrets and information from the use of your actual or potential competition. This therefore means that the NDA or CA will ensure that one or both parties who enter into the agreement by signing the contract do not disclose the protected/confidential business information or even the unlawful use of the information. In the context of unilateral confidential contracts, only a party who signs the agreement agrees not to disclose certain information. The non-signatory party is the one that tries to keep the information confidential. On the other hand, bilateral INAs are those for which the parties concerned have private information that they must both protect. Bilateral agreements are common in joint ventures and partnerships.
