A confidentiality agreement (NDA), also known as a confidentiality agreement (CA), a confidential disclosure agreement (CDA), a protected information agreement (PIA) or a confidentiality agreement (SA), is a legal contract or part of a contract between at least two parties that describes documents, knowledge or confidential information that the parties wish to share for specific purposes. but restrict access. Doctor-patient confidentiality (doctor-patient privilege), lawyer-client privilege, priestly penance privilege, bank-client confidentiality and kickback agreements are examples of NDAs that are often not written into a written contract between the parties. This is a contract by which the parties agree not to disclose the information covered by the agreement. An NDA creates a confidential relationship between the parties, usually to protect any type of confidential information and proprietary or trade secrets. Therefore, an NDA protects non-public business information. Like all treaties, they cannot be applied if the contractual activities are illegal. DDNs are often signed when two companies, individuals or other entities (such as partnerships, companies, etc.) are considering doing business and need to understand the processes used in the other`s activities to assess the potential business relationship. DDAs may be « reciprocal », meaning that both parties are limited in their use of the materials supplied, or may restrict the use of materials by a single party.
An employee may be required to sign an NDA or NDA-type agreement with an employer to protect trade secrets. A confidentiality agreement (NDA) can be considered unilateral, bilateral or multilateral: a multilateral NDA can be beneficial, since the parties only re-execute, execute and implement an agreement. This advantage can, however, be offset by more complex negotiations that may be necessary to enable the parties concerned to reach a unanimous consensus on a multilateral agreement. A confidentiality agreement can protect any type of information that is not known to everyone. However, confidentiality agreements may also contain clauses protecting the person receiving the information, so that if they have lawfully obtained the information through other sources, they would not be required to keep the information secret.  In other words, the confidentiality agreement generally requires that the party receiving information remain confidential if that information was provided directly by the party to the disclosure. . . .
