The first decision when drafting or reviewing an NDA is choosing between a mutual and unilateral structure. Get this wrong and you either under-protect your own information or impose unnecessary obligations on yourself. Here's how to choose the right type for your situation.
Unilateral NDA: One-Way Confidentiality
A unilateral NDA — also called a one-way or one-sided NDA — creates confidentiality obligations for only one party: the receiver. Only one party is disclosing confidential information, and only the other party is bound to protect it.
Typical scenario: A client shares their business plans, technical specifications, or customer data with a freelancer before the engagement begins. The client is the Disclosing Party; the freelancer is the Receiving Party. The freelancer is bound; the client is not.
Unilateral NDAs are appropriate when:
- Only one party has confidential information to protect
- The relationship is clearly one-directional (client briefing contractor)
- You are the service provider and the client is sharing their business information with you
Mutual NDA: Two-Way Confidentiality
A mutual NDA — also called a bilateral or two-way NDA — creates confidentiality obligations for both parties. Both sides share confidential information; both sides are bound to protect what they receive.
Typical scenarios for mutual NDAs:
- Two businesses exploring a potential partnership or joint venture
- A freelancer sharing a proprietary methodology or pricing model with a client
- A subcontractor and a lead agency working together on a shared project
- Two freelancers collaborating and sharing each other's client information
When Should a Freelancer Use a Mutual NDA?
As a freelancer, a mutual NDA makes sense when you are sharing something genuinely proprietary with the client — not just performing a service. Examples include:
- A proprietary consulting framework or methodology
- Detailed pricing structures or cost models
- Your own process documents, templates, or tools that you share for evaluation
- Technical architectures or systems you've built that you're demonstrating as part of a pitch
If you're simply performing web design, writing, or development using the client's brief and information — and not sharing any proprietary information of your own — a unilateral NDA where the client is the disclosing party is usually sufficient.
When Clients Insist on a Mutual NDA
Many large companies use mutual NDAs as a matter of standard policy for all vendors, regardless of what's actually being shared. This is common and generally not a problem. If a client presents you with a mutual NDA when only they will be disclosing information:
- You have no confidential information to share = no relevant obligations triggered on your side
- The agreement protects the client's information in exactly the same way a unilateral NDA would
- Signing is usually fine — just ensure the definition of confidential information doesn't inadvertently capture things you don't want to protect
Key Structural Differences
In a unilateral NDA, the agreement refers to "the Disclosing Party" and "the Receiving Party" throughout. In a mutual NDA, both parties are simultaneously both disclosing and receiving, so the agreement either uses "Party A" and "Party B" symmetrically, or refers to "each party" in obligations that apply to both sides.
The obligations themselves — what counts as confidential, duration, permitted uses, exclusions, return of materials — are usually identical in both types. The only real difference is which party bears those obligations.
Risks to Watch For
In a mutual NDA, watch for:
- An overly broad definition of confidential information on your side — if the client can claim everything you discuss is confidential, your future work could be restricted
- Obligations that would prevent you from working in similar areas after the engagement
- Different duration terms for each party (unusual but not unheard of)
- Dispute resolution provisions that require you to litigate in the client's jurisdiction

What is a unilateral NDA?
A unilateral NDA binds only one party — the receiver — to confidentiality. Only one party is disclosing confidential information. This is the most common type in freelancing: the client shares information with the freelancer, and the freelancer agrees to keep it secret.
What is a mutual NDA?
A mutual NDA binds both parties to confidentiality. Both parties share confidential information with each other and both have obligations to protect what they receive. Common in partnerships, joint ventures, and negotiations where both sides share sensitive details.
Which NDA should a freelancer use?
Most freelancers need a unilateral NDA where the client is the disclosing party. Use a mutual NDA when you are also sharing proprietary information with the client — for example, a proprietary methodology, pricing structure, or creative process you want protected.
Can a client insist on a mutual NDA even if only they are disclosing information?
Yes, and this is common. Many companies use mutual NDAs as standard policy for all vendors. If only the client is disclosing information, signing a mutual NDA simply means your obligations under your half of the agreement are never triggered.
Does a mutual NDA protect my pricing and processes?
Yes, if your proposals, pricing, methodologies, and processes are included in the definition of confidential information. Make sure the mutual NDA's definition covers the types of information you share — not just the client's information.
