What type of agreement may prevent one party from disclosing sensitive information?

A non-disclosure agreement (NDA) is specifically designed to protect sensitive information shared between parties. The key function of an NDA is to create a legal obligation for one or both parties to keep certain information confidential. This is particularly important in business contexts where proprietary information, trade secrets, or sensitive data are shared, and where the disclosing party wants to retain control over how that information is used and who has access to it.

In contrast, a lease agreement generally pertains to the rental of property and does not focus on confidentiality. A partnership agreement outlines how partners in a business will operate, their roles, and profit-sharing, but it does not inherently include clauses about disclosing sensitive information unless explicitly stated. An employment agreement may include confidentiality provisions, but it serves a broader purpose of defining the employee's role and terms of employment rather than focusing solely on the protection of sensitive data.

Thus, the non-disclosure agreement stands out as the most appropriate instrument for preventing the disclosure of sensitive information.
