How to Write an NDA: Free Template and Best Practices

A Non-Disclosure Agreement (NDA) is one of the most common business documents you'll encounter. Whether you're sharing a business idea with a potential partner, hiring a contractor, or entering negotiations with a vendor, an NDA protects your confidential information from being shared or misused.

This guide covers everything you need to know about writing an effective NDA.

What Is an NDA?

An NDA (also called a confidentiality agreement) is a legally binding contract that creates a confidential relationship between parties. The party sharing information (the disclosing party) is protected against unauthorized disclosure by the party receiving it (the receiving party).

Mutual vs. Unilateral NDAs

Unilateral NDA

One party shares confidential information, and the other agrees not to disclose it.

Common use cases:

Hiring a freelancer or contractor
Sharing a business plan with potential investors
Employee onboarding

Mutual NDA (Bilateral)

Both parties share confidential information and agree to protect each other's data.

Common use cases:

Business partnerships and joint ventures
Merger and acquisition discussions
Technology licensing negotiations

When to use which: If both parties will share sensitive information, use a mutual NDA. If only one party is sharing, a unilateral NDA is sufficient.

Essential Sections of an NDA

1. Definition of Confidential Information

This is the most critical section. Be specific about what's covered:

Business plans, strategies, and financial data
Customer lists and vendor relationships
Trade secrets, formulas, and processes
Software code, algorithms, and technical specifications
Marketing plans and pricing strategies

Tip: Include a catch-all phrase like "and any other information marked as confidential" but don't rely on it alone. Courts prefer specific definitions.

2. Exclusions from Confidentiality

Standard exclusions protect the receiving party from unreasonable claims:

Information that was already publicly known
Information the receiving party already possessed
Information independently developed by the receiving party
Information received from a third party without confidentiality obligations
Information disclosed pursuant to a court order (with notice to the disclosing party)

3. Obligations of the Receiving Party

What the receiving party must do (and not do):

Not disclose confidential information to third parties
Use the information only for the stated purpose
Protect the information with reasonable security measures
Limit access to employees and agents who need to know
Return or destroy confidential materials upon request

4. Term and Duration

Two time periods to define:

Agreement term: How long the NDA relationship lasts (typically 1-5 years)
Confidentiality duration: How long the confidentiality obligation survives after the agreement ends (often 2-5 years, sometimes indefinite for trade secrets)

5. Remedies for Breach

What happens if someone violates the NDA:

Injunctive relief: The disclosing party can seek a court order to stop further disclosure
Monetary damages: Compensation for losses caused by the breach
Attorney's fees: The breaching party pays legal costs

6. Governing Law and Jurisdiction

Specify which state/country's laws govern the agreement and where disputes will be resolved.

Common NDA Mistakes

1. Being Too Vague

"All business information" is too broad. Courts may find it unenforceable. Be specific about what's confidential.

2. Making It Too Broad

An NDA that covers everything the receiving party learns, sees, or hears is likely unenforceable. Reasonable scope is key.

3. Setting an Unreasonable Duration

A 20-year confidentiality period for general business information will raise eyebrows. Match the duration to the sensitivity of the information.

4. Forgetting the Exclusions

Without standard exclusions, the receiving party takes on unreasonable risk, and a court may invalidate the entire agreement.

An NDA is useless if you share confidential information before it's executed. Always sign first, share second.

Best Practices

Use a template as a starting point, but customize it for each situation
Have a lawyer review NDAs for high-stakes situations
Sign before sharing any confidential information
Keep records of what information was shared and when
Use e-signatures for faster execution and a clear audit trail
Set calendar reminders for expiration dates
