MNDA vs NDA: Key Differences and Best Practices
Learn the key differences between MNDAs and NDAs, including their uses, advantages, and best practices to protect confidential business information effectively. 5 min read updated on November 15, 2024
Key Takeaways:
- MNDA vs NDA: MNDA (Mutual Non-Disclosure Agreement) and NDA (Non-Disclosure Agreement) differ primarily in reciprocity. MNDAs bind both parties, while NDAs usually bind only one.
- Choosing Between MNDA and NDA: The choice depends on the nature of the business relationship and the sensitivity of shared information.
- Key Elements of an NDA/MNDA: Confidentiality clauses, scope definitions, timelines, and exceptions are crucial components.
- Third-Party Responsibility: NDAs should address whether third parties involved are bound to confidentiality and who bears responsibility for breaches.
- Best Practices: Limit disclosures to essentials, define timelines carefully, and consider residual clauses for shared information.
Mutual NDA vs NDA are two types of NDAs, or non-disclosure agreements, in the U.S. They are usually used to protect certain confidential information from wrong exposure, theft, or misuse. They are used to protect:
- Intellectual property rights.
- Trade secrets.
- Customer lists.
- Company business plans.
- Valuable proprietary information.
When an entity wants to share valuable trade information with another party, an NDA should be drafted and signed.
Unilateral or Mutual
When drafting an NDA, you must choose between a mutual or unilateral NDA. In a unilateral NDA, one party agrees to non-disclosure of confidential information belonging to the other party. In a mutual NDA, both parties agree not to reveal the other's confidential information.
The choice between these two kinds of NDA is important since the final outcome depends on several factors including bargaining power and whether or not the non-disclosure of confidential information is agreed to by one or both parties.
When to Use an MNDA vs. an NDA
Determining whether to use an MNDA or an NDA depends on the type of relationship and the level of trust between parties:
- Use an MNDA when both parties will share sensitive information, such as in potential partnerships, mergers, or joint ventures. This ensures mutual protection.
- Use an NDA in cases where only one party shares confidential information, such as hiring independent contractors or sharing business secrets with vendors.
The choice also depends on factors like negotiating power and legal preferences. For instance, companies with strong intellectual property protections may favor unilateral NDAs to maintain a competitive edge.
Receiving Party vs. Disclosing Party
The party that receives the confidential information is known as the receiving party while the party that is disclosing the information is referred to as the disclosing party.
Recipients, especially potential buyers, may need to share the confidential business information of the disclosing party with its consultants, employees, and, in some cases, debt and equity financing sources.
Therefore, the recipient must ensure that the clauses in the NDA allow sharing. If this is not possible, the NDA should at least have a provision allowing the recipient to obtain consent in order to share the disclosed information with necessary third parties. There shouldn't be an unnecessary delay or unreasonable withholding of such consent.
Legal Responsibility for Third Parties
Whether the third parties become subject to the terms of the NDA or not, disclosing parties should add a clause to the NDA holding the recipient legally responsible for any disclosure of confidential information by its employees or third parties that violate the terms of the NDA.
Addressing Residual Knowledge in NDAs
Residual knowledge refers to information retained in the minds of individuals even after an NDA is terminated. Some NDAs include clauses permitting the use of residual knowledge, while others explicitly prohibit it. Including a residual knowledge clause can:
- Protect businesses from accidental misuse of retained information.
- Clarify the boundaries of what is considered a breach.
It’s advisable to limit residual clauses to publicly known or independently derived information to minimize risks.
Non-Use & Non-Disclosure Obligations
The NDA's core element is the obligation not to disclose or use the confidential information of the other party. Usually, an NDA stipulates that receiving parties:
- Cannot disclose confidential information to other entities.
- Cannot use confidential information to their own advantage.
- Will use reasonable efforts to safeguard the confidential nature of the disclosed information.
It's good practice to include clauses that allow recipients to disclose the information to entities such as accountants, lawyers, and certain parties — as long as these entities sign an agreement not to reveal confidential information.
The scope of an NDA is determined by the term “Confidential Information.” Confidential information can refer to all disclosed information or information contained in a stamped document. However, the scope varies since most definitions of the term include all information deemed by a reasonable person to be confidential.
However, you should include exceptions to the term — for instance, information that recipients can obtain from other sources or information that is commonly known in the industry.
Customizing Confidentiality Clauses
Confidentiality clauses should be tailored to the unique needs of the agreement:
- Define Confidential Information Clearly: Use specific terms to avoid disputes.
- List Acceptable Disclosures: Allow disclosures to legal counsel, accountants, or regulatory bodies, as needed.
- Include Exceptions: Specify exclusions for publicly available information or data acquired independently without breaching the agreement.
- Detail Non-Use Obligations: Ensure the receiving party cannot use the information to compete or gain unfair advantage.
This customization can strengthen enforceability and clarify obligations.
Length of NDA Obligations
You should specify a timeline for NDAs. If you create an NDA for potential business relationships, it should have a short tenure — one year, for example. The timeline for NDAs created for larger ongoing agreements should correspond with the agreement's termination date. However, it's good practice to add a time period ranging from one to five years after the termination of agreements.
For statutorily protected trade secrets, NDA protection should survive for the maximum time provided by the state's trade secret law.
You should only work with entities that you believe are trustworthy and operate with integrity. An NDA won't stop unscrupulous entities from copying your business model. Although you can sue these entities, lawsuits are often expensive, time-consuming, and energy-draining.
Also, you shouldn't disclose confidential proprietary information in a manner that allows the receiving part to retain copies of said information. If you must reveal your business model, only reveal sections that are very necessary to the business at hand. Never reveal everything. You should always reserve your key secret — the methods used in achieving your business model.
Recipients may want to add residual clauses to the NDA stipulating that some information that the recipient shares with its team is not treated as confidential. Such information is usually retained in the “unaided” memories of the team members.
Legal Enforcement of NDAs and MNDAs
For both NDAs and MNDAs, enforcement is critical to protecting sensitive data. Key factors influencing enforcement include:
- Jurisdiction: Specify the governing state laws.
- Remedies for Breach: Outline remedies such as injunctions, damages, or legal fees.
- Binding Nature: Ensure the agreement explicitly states it is legally binding.
Proactively updating NDAs to reflect changes in laws, such as trade secret statutes, can safeguard enforceability.
