NDA Basics: When and How to Use Non-Disclosure Agreements

NDAs protect sensitive information in business relationships. They're one of the most common legal documents you'll encounter—and one of the most misunderstood.

This guide covers when you actually need an NDA, what to include, and how to create one that's enforceable.

What is an NDA?

A Non-Disclosure Agreement (also called a confidentiality agreement) is a legal contract that prevents parties from sharing confidential information with others.

There are two main types:

• One-way (Unilateral) — One party shares confidential information, the other agrees to keep it secret
• Mutual (Bilateral) — Both parties share and protect each other's confidential information

When Do You Need an NDA?

1. Before Pitching to Investors

Protect your business idea, financials, and proprietary information when seeking funding. Note: Some investors refuse to sign NDAs before initial meetings—know your leverage.

2. Hiring Employees or Contractors

Protect trade secrets, proprietary methods, and client information. Often included as part of employment agreements.

3. Discussing Partnerships or Joint Ventures

Share enough information to evaluate opportunities while protecting your competitive advantage.

4. Sharing Prototypes or Demos

Prevent copying before your product launches. Essential during product development and beta testing.

5. Due Diligence in M&A

Buyers need detailed information to evaluate acquisitions. Sellers need protection if the deal falls through.

6. Working with Vendors or Suppliers

Protect customer data, pricing strategies, and internal processes when outsourcing.

When You Don't Need an NDA

Overusing NDAs slows business and can damage relationships. Skip the NDA if:

• The information is already publicly available
• You're sharing with parties already covered by existing agreements
• The relationship is too casual (initial networking, general discussions)
• The other party has no practical use for the information

Key Clauses in Every NDA

1. Definition of Confidential Information

Be specific about what's covered. Include written, oral, and electronic information. Carve out exclusions for:

• Information that's already public
• Information independently developed by the receiving party
• Information required to be disclosed by law

2. Obligations of the Receiving Party

Clearly state what the recipient must do:

• Keep information confidential
• Only share with authorized personnel
• Use information only for the stated purpose

3. Time Period

How long does the confidentiality obligation last? Typical periods range from 2-5 years after disclosure. Some information (trade secrets) may warrant indefinite protection.

4. Permitted Disclosures

Specify who can access the information:

• Employees with a need to know
• Legal or regulatory authorities (with notice to the disclosing party)

5. Return or Destruction of Information

What happens when the relationship ends? Typically, the receiving party must return documents and delete digital copies.

6. Governing Law

Which jurisdiction's laws apply if there's a dispute? Important for cross-border relationships.

Mutual vs One-Way: Which to Use?

Rule of thumb: If both parties share sensitive information, use mutual. If only one party shares, use one-way.

Common NDA Mistakes

1. Being too vague about what's confidential. Courts may not enforce overly broad definitions.
2. Making it too broad—trying to protect things that can't legally be protected (like general skills or publicly available information).
3. Unreasonable time periods that courts won't enforce. 2-5 years is standard for most business information.
4. No carve-outs for legally required disclosures. Courts can compel disclosure; your NDA should acknowledge this.
5. Wrong jurisdiction for governing law. Choose a jurisdiction with clear legal precedent.
6. Forgetting to get it signed before sharing information. An NDA is useless if signed after disclosure.

How to Create and Send an NDA

Option 1: Use a Template (Recommended for Most Cases)

• Start with a proven structure
• Customize for your specific situation
• Send for e-signature

signready.co's NDA template lets you generate a customized NDA in minutes. Fill in the parties and key terms, then send for signature.

Option 2: Have a Lawyer Draft (For Complex Situations)

Consider legal counsel for high-stakes deals, unusual circumstances, or when significant money is at risk. More expensive and slower, but may be worth it.

Frequently Asked Questions

Are e-signed NDAs legally binding?

Yes. Electronic signatures are legally equivalent to handwritten signatures under ESIGN and eIDAS regulations.

Can I use the same NDA for everyone?

You can use the same template, but review and customize for each situation. The definition of confidential information and the purpose of disclosure may vary.

What if someone breaks the NDA?

You can pursue legal remedies including injunctions (court orders to stop further disclosure) and monetary damages. Document everything if you suspect a breach.

Do NDAs expire?

The confidentiality obligation typically has a defined period (often 2-5 years from disclosure). After that, the information may no longer be protected—though trade secrets can have longer or indefinite protection.
