If you run a small business or work as a freelancer, you have probably been in a situation where you needed to share sensitive information — a client list, a product roadmap, pricing strategies, or proprietary processes. The question is always the same: how do you protect that information once it leaves your hands?
The answer is a non-disclosure agreement (NDA). And creating one is far simpler than most people think.
This guide walks you through the entire process of creating an NDA, from understanding when you need one to drafting a document that actually holds up in court.
What Is an NDA and Why Do You Need One?
A non-disclosure agreement is a legally binding contract between two or more parties that restricts the sharing of confidential information. It establishes what information is protected, who is bound by the agreement, how long the protection lasts, and what happens if someone violates the terms.
NDAs are used in virtually every industry:
- Freelancers and contractors use NDAs before starting client projects that involve proprietary data
- Startups use NDAs when pitching to investors or discussing partnerships
- Small businesses use NDAs when hiring employees who will access trade secrets
- Landlords and property managers use NDAs for sensitive financial or tenant information
- Consultants use NDAs before conducting audits or reviewing internal processes
Without an NDA, you have limited legal recourse if someone shares your confidential information. Verbal agreements are notoriously difficult to enforce. A written NDA gives you a clear, enforceable mechanism to protect what matters most to your business.
Mutual vs. Unilateral NDAs: Which Do You Need?
Before you start drafting, you need to decide which type of NDA fits your situation.
Unilateral NDA
One party discloses confidential information; the other party agrees not to share it. This is the most common type.
Use when:
- Hiring a freelancer or contractor
- Onboarding a new employee
- Sharing your business plan with an advisor
- Giving a vendor access to internal systems
Mutual NDA (Bilateral)
Both parties share confidential information with each other and both agree to keep it private.
Use when:
- Entering a business partnership or joint venture
- Negotiating a merger or acquisition
- Collaborating on a product with another company
- Exploring a licensing deal
Rule of thumb: If only one side is sharing sensitive information, use a unilateral NDA. If both sides are, use a mutual NDA. When in doubt, a mutual NDA protects everyone and is rarely objected to.
The 7 Essential Clauses Every NDA Must Include
A strong NDA is not about length — it is about covering the right ground. Here are the clauses that separate an enforceable NDA from one a court might throw out.
1. Definition of Confidential Information
This is the most important clause. Be specific about what counts as confidential. Vague definitions like "all information shared between the parties" are difficult to enforce.
Strong example:
Confidential Information includes, but is not limited to: customer lists, pricing models, proprietary software code, marketing strategies, financial projections, and any information marked as "Confidential" at the time of disclosure.
Weak example:
All information shared during the business relationship.
2. Obligations of the Receiving Party
Spell out exactly what the receiving party must do (and must not do) with the information. Typical obligations include:
- Not disclosing the information to third parties without written consent
- Using the information only for the stated purpose
- Taking reasonable measures to protect the information (e.g., password protection, limited access)
- Returning or destroying all confidential materials upon termination
3. Exclusions from Confidentiality
No NDA covers everything. Standard exclusions include information that:
- Was already publicly available at the time of disclosure
- Was independently developed by the receiving party
- Was received from a third party with no confidentiality obligation
- Must be disclosed by law or court order
These exclusions are standard and expected. Omitting them can actually make your NDA harder to enforce because courts view overly restrictive agreements with skepticism.
4. Duration of the Agreement
How long does the NDA last? Most NDAs specify a term of 1 to 5 years, though trade secrets may warrant longer or even indefinite protection.
Consider:
- Project-based work: Duration of the project plus 1–2 years
- Employment: Duration of employment plus 2–3 years
- Trade secrets: 5+ years or indefinite (check your jurisdiction — some states limit this)
5. Governing Law and Jurisdiction
Which state or country's laws apply if there is a dispute? This clause prevents costly arguments about where a lawsuit should be filed.
Always specify the jurisdiction where your business is incorporated or operates. For example: "This Agreement shall be governed by and construed in accordance with the laws of the State of California."
If you operate in a specific jurisdiction, Contract.diy creates NDAs tailored to your state's requirements, including jurisdiction-specific enforceability standards.
6. Remedies for Breach
What happens if someone breaks the NDA? Common remedies include:
- Monetary damages — compensation for financial loss caused by the breach
- Injunctive relief — a court order requiring the breaching party to stop the disclosure
- Indemnification — the breaching party covers legal costs and damages
Including a remedies clause signals to both parties that the agreement has real consequences.
7. Signature Blocks and Effective Date
The NDA must be signed by all parties (or their authorized representatives) and include the date the agreement takes effect. Without signatures, you do not have a contract.
Include:
- Full legal names of all parties
- Titles or roles (e.g., "CEO," "Independent Contractor")
- Date of signature
- Addresses for notices (so you can formally communicate if a breach occurs)
Common NDA Mistakes to Avoid
Even well-intentioned NDAs can fall apart because of avoidable errors. Here are the most common ones:
Being Too Vague About What Is Confidential
If your NDA says "everything we discuss is confidential," a court may find it unenforceable. Be specific. List categories of information and provide examples.
Setting an Unreasonable Duration
An NDA that lasts "forever" for general business information will raise red flags with any judge. Match the duration to the sensitivity of the information. Trade secrets deserve longer protection than project timelines.
Forgetting the Exclusions Clause
Without standard exclusions, you may accidentally claim ownership over information that was already public or independently created. This weakens your entire agreement.
Using a One-Size-Fits-All Template
An NDA for a freelance design project is different from an NDA for a software development partnership. The clauses, scope, and duration should reflect the actual relationship and the type of information being shared.
Not Specifying Jurisdiction
If you skip governing law, you may end up arguing about where to file a lawsuit before you even get to the substance of the dispute. Always specify.
Not Having Both Parties Sign
It sounds obvious, but unsigned NDAs are surprisingly common — especially when agreements are exchanged via email and "agreed to verbally." Always get a signature.

The entire process takes less than five minutes and produces a document that covers all seven essential clauses described above.
When Should You Not Use an NDA?
NDAs are powerful tools, but they are not always the right choice:
- Casual networking conversations — Asking someone to sign an NDA before a coffee meeting creates friction and signals distrust
- Information that is already public — If the information is on your website or in a press release, an NDA adds nothing
- When you lack leverage — If you are pitching to a large company that refuses to sign NDAs, pushing the issue may cost you the opportunity. In these cases, be selective about what you share instead
- Job interviews (for most roles) — Unless the role involves immediate access to trade secrets, an NDA before an interview can deter candidates
