Imagine two companies entering a promising collaboration—excited to share confidential information and innovate together. They sign what they think is a straightforward confidentiality agreement, only to discover post-signature that certain key clauses are ambiguous or unfavorably one-sided. Weeks later, a misunderstanding over what information was protected escalates into a costly dispute, delaying the project and damaging trust.
This scenario is far too common when organizations don’t fully grasp the differences between types of non-disclosure agreements (NDAs), or when critical contract deviations go unnoticed during drafting. Fortunately, advances in AI-powered contract technologies now enable stakeholders to identify risky or non-standard clauses early in the process, reducing costly surprises and fostering healthier partnerships.
This article breaks down the distinctions between Mutual NDAs (MNDAs) and unilateral NDAs, clears up common confusions, and explains how artificial intelligence (AI) can flag unusual contract terms during creation—helping businesses stay compliant and protect their interests effectively.
What Exactly Is an NDA? And How Does an MNDA Differ?
At its core, an NDA (Non-Disclosure Agreement) is a legal contract designed to protect confidential information shared between parties during discussions, transactions, or collaborations. NDAs establish ground rules on what information must be kept secret, how it can be used, and for how long confidentiality lasts.
The Basic NDA Types
- Unilateral NDA (One-Way NDA): One party discloses confidential information, and the other party agrees to keep it secret. This structure is common when an employer shares proprietary details with an employee, or when a company provides sensitive information to a vendor or contractor.
- Bilateral or Mutual NDA (MNDA): Both parties anticipate sharing confidential information and agree to protect each other’s data reciprocally. This is typical for collaborations, joint ventures, co-development projects, mergers and acquisitions due diligence, and strategic partnerships.
Despite the name, “mutual” NDAs can vary widely in their actual terms and scope, so it’s important to understand the nuances before choosing or drafting an agreement.
| Feature / Attribute | Unilateral NDA | Mutual NDA (MNDA) |
| Information Flow | One-way disclosure | Two-way disclosure |
| Number of Disclosing Parties | Single disclosing party | Both parties disclose |
| Confidentiality Obligations | Imposed only on the recipient | Imposed on both parties |
| Protection Structure | One-sided protection | Reciprocal protection |
| Typical Use Scenarios | Employee onboarding, contractor access, vendor evaluation, solo idea pitches | Strategic partnerships, joint R&D, M&A due diligence, joint ventures |
| Balance of Risk | Higher risk on the receiving party | Shared risk responsibilities |
Understanding which NDA type fits your business context is crucial. Selecting the wrong agreement or misdrafting clauses can expose you to greater risk—overly broad obligations, unclear duration, or poor handling of residual knowledge are typical pitfalls.

What Are the Key Clauses to Watch for in NDAs and MNDAs?
While NDA templates often seem standardized, every contract involves layers of nuance. Certain clauses directly impact how well confidentiality protections serve your interests.
Here are the foundational NDA clauses that deserve careful attention:
- Definition of Confidential Information: Precisely list what kinds of information are protected—whether it’s technical data, business plans, financials, or intellectual property. Avoid vague definitions that can lead to interpretation disputes.
- Scope of Use: Clarify how the receiving party may use the confidential information, typically limited to evaluating or pursuing the collaboration.
- Term and Duration: Set clear time frames for how long the confidentiality obligation lasts, including any survival periods after the agreement ends.
- Exclusions: Standard exclusions include publicly available information, information already known to the receiving party, or data independently developed. Defining these prevents unnecessary disputes.
- Residue Clause: Addresses residual knowledge or “memory” that might remain with the receiving party, like skills or ideas not directly traceable to disclosed confidential info. This is often overlooked but can cause value leakage.
- Third-Party Flow-Down: Indicate whether confidentiality obligations extend to subcontractors or advisors who access the information.
- Return or Destruction of Materials: Requirements for how confidential materials should be handled post-collaboration.
- Governing Law and Remedies: Specifies jurisdiction and available legal remedies in case of breach.
The interplay of these clauses ultimately determines how effective and enforceable an NDA or MNDA will be.
Why It’s Easier to Miss Risky or Non-Standard Clauses Than You Think
Even seasoned professionals can find drafting or reviewing NDAs challenging. Subtle variations or poorly worded provisions can change risk exposure dramatically. Common challenges include:
- Non-Standard or Deviated Clauses: Parties sometimes insert unfamiliar liability disclaimers, indefinite survival clauses, overly broad definitions, or ambiguous exceptions that can undermine confidentiality protections.
- Jurisdictional Variances: Legal enforceability and valid clause structures may differ by country or industry, requiring tailored language.
- Human Error: Overlooking typos, contradictory provisions, or missing key clauses during tedious manual reviews is common.
- Residual Risk: Underestimating how “residual knowledge” can inadvertently allow information leaks long after NDA termination.
Given these challenges, relying solely on manual review is often insufficient—especially for organizations managing large volumes of contracts or complex collaborations.
How AI Can Spot Non-Standard Clauses and Flag Risks Early in Contract Creation
Artificial intelligence is increasingly transforming contract lifecycle management by providing sophisticated, automated clause analysis. Here’s how AI adds value in NDA and MNDA drafting:
- Automated Clause Identification: AI models trained on thousands of contracts can scan documents to highlight non-standard or atypical clauses compared with industry norms or your organization’s baseline templates.
- Risk Flagging and Scoring: When unusual or risky language is detected—such as ambiguous scope, indefinite confidentiality periods, or missing critical protections—AI flags these for further review with explanations.
- Prompting Safer Alternatives: AI-enabled CLM platforms can suggest alternative clause wording proven to reduce risk, guiding contract authors toward more secure language.
- Consistency Checks: Monitoring that definitions, terms, and clauses align throughout the contract to avoid contradictions.
- Cross-Contract Comparison: Comparing new NDA drafts with historical agreements or approved templates to ensure compliance with organizational policies.
- Learning from Outcomes: AI tools can integrate post-signature monitoring data to refine clause risk assessments over time, improving detection efficiency.
By embedding AI-powered clause identification in the contract authoring phase, organizations gain early visibility into potential compliance issues and vulnerabilities. This proactive approach can reduce value leakage by 5-10%, as industry research suggests, and prevent disputes before they arise.
