What Is a Non-Disclosure Agreement (NDA)?

A Non-Disclosure Agreement, commonly known as an NDA or confidentiality agreement, is a legally binding contract between two or more parties that establishes a confidential relationship. The party or parties who sign the agreement commit to keeping specific information secret and not disclosing it to third parties without authorisation. NDAs are one of the most frequently used legal documents in business, protecting everything from product ideas and trade secrets to client lists and financial data.

Mutual vs One-Way NDAs: Which Do You Need?

There are two primary types of non-disclosure agreements:

• Mutual NDA (Bilateral): Both parties agree to keep each other's information confidential. This is common in joint ventures, mergers, or partnership discussions where both sides are sharing sensitive data.
• One-Way NDA (Unilateral): Only one party shares confidential information with the other. This is the most common type, used when hiring employees, engaging contractors, or pitching ideas to investors.

ClauseKit's NDA generator lets you choose the type that suits your situation and tailors the agreement language accordingly.

When Should You Use an NDA?

You should use a non-disclosure agreement whenever you are sharing information that gives your business a competitive advantage. Common situations include:

• Hiring new employees or contractors who will have access to proprietary systems
• Entering into discussions with a potential business partner or investor
• Sharing your app, software, or product concept with a developer
• Engaging a marketing agency with access to your customer data
• Conducting due diligence during a merger or acquisition

Are NDAs Legally Enforceable?

Yes, NDAs are legally enforceable contracts in most jurisdictions around the world, provided they meet certain requirements. The agreement must clearly define what constitutes confidential information, specify a reasonable time period for the obligation, and not restrict activities that are unreasonably broad. Courts in the US, UK, EU, and most other countries regularly uphold properly drafted NDAs.

It is important to note that NDAs cannot protect information that is already publicly known, independently developed by the receiving party, or obtained through legal means from a third party. These are known as standard NDA exclusions.

What Happens If Someone Breaks an NDA?

If someone violates the terms of an NDA, the disclosing party can take legal action. Remedies typically include seeking an injunction to stop further disclosure, claiming damages for financial losses caused by the breach, and in some cases, claiming liquidated damages if the NDA includes a predetermined penalty clause. The strength of your legal position depends heavily on how well your NDA is drafted, which is why using a professional template matters.
