Demystifying the Nondisclosure Agreement

By Richard E. Neff, June 17, 2010: Reprinted and/or reposted with the permission of Daily Journal Corp. (2010).


One of the shortest and simplest legal agreements is the nondisclosure agreement, sometimes called “confidentiality agreement.” A good nondisclosure agreement can be one page in length. It generally exists to cover just two scenarios: (the obvious one is to prevent the disclosure of a party’s confidential information to third parties (and to anyone who does not really need the information); and the less obvious one is to prevent the use by the recipient for anything but the limited purpose for which the disclosure has been made. If the nondisclosure agreement covers both of these scenarios adequately, it probably is a decent agreement. But many nondisclosure agreements do not fully protect the discloser.

The nondisclosure agreement can be mutual, protecting against disclosure and unauthorized use of confidential information by either party as recipient. In other words, a mutual nondisclosure agreement anticipates that there will be a flow of confidential information in both directions between the parties entering into the agreement, so each is subject to obligations that should be parallel or nearly so. A one-way nondisclosure agreement means that it is anticipated that one party will be disclosing confidential information to the other party (the recipient), and so only the recipient is obligated to protect the confidential information from disclosure or from use that is broader than permitted under the nondisclosure agreement.

First, “confidential information” must be defined. In part, that definition might be context-specific. For example, if you are representing the inventor of a watch that also keeps golf scores, the definition might specifically reference “inventions, including without limitation those relating to watches and timepieces.” A good general provision might define confidential information as “any nonpublic information, technical data or know-how, including that relating to research, business processes, inventions, software programs, technical documentation, specifications, designs, drawings, engineering, products, services, customers, markets, or finances of the discloser.” To the extent practical, confidential information should be marked as such.

If it is disclosed orally, this should be confirmed in writing (even by e-mail) within 30 days of oral disclosure. But the definition of confidential information must acknowledge that there are various exceptions and carve-outs: a piece of confidential information might become public and therefore no longer be confidential information; the recipient might already know or possess the confidential information because it has developed it or has received the information from another source. In the latter case, the recipient should be able to demonstrate this. Finally, the recipient needs the right to be able to disclose confidential information if required to do so by court or administrative order, subject to certain restraints.

Because the nondisclosure agreement is a dual purpose agreement that aims to prevent unauthorized disclosure and unauthorized use, the scope of use/disclosure has to be defined. A good nondisclosure agreement begins with a strong purpose clause. The more specific the purpose clause, the more unauthorized use/disclosure can be prevented. However, often the purpose of the disclosure is to permit the evaluation of a business relationship between the parties, or perhaps an investment in the discloser by the recipient. In such cases, the disclosure should be limited to “those employees (or subcontractors) of the recipient having a need to know the confidential information in order to achieve the purpose and who are subject to written confidentiality agreements that protect the confidential information of discloser as much as this agreement, and the attorneys and accountants of the recipient having a need to know.” It would be dangerous to permit the recipient to share what may be quite a novel concept with any third party. If the recipient wishes to disclose confidential information beyond a narrowly defined circle, the express written authorization of the discloser should be required.

Additional requirements of the good nondisclosure agreement include the following:
