A unilateral NDA — also called a one-way NDA — is a confidentiality agreement where one side shares secret information and the other side promises to protect it. Only one party discloses. Here's exactly what that means, when to use one, and how to generate a signature-ready one free.
Create an NDA free →What a unilateral NDA is
In a unilateral NDA, one party — the disclosing party — shares confidential information, and the other — the receiving party — agrees to keep it secret and not misuse it. The obligations run one way: only the receiver is bound. It's often just called a one-way NDA.
When to use one
Reach for a unilateral NDA whenever only you disclose: pitching an idea to a contractor or agency, sharing figures with a potential investor, onboarding a freelancer or employee, or showing a prototype to a manufacturer. If only your information is at risk, a one-way agreement is enough.
Unilateral vs mutual — the difference
In a unilateral NDA only one side shares and is protected. In a mutual (bilateral) NDA both sides share and both are bound. If the other party will also reveal something confidential — a partnership or joint venture, say — use a mutual NDA instead so the protection runs both ways.
What a unilateral NDA includes
Whatever the direction, a solid NDA covers the same essentials:
- The parties — who discloses and who receives
- A clear definition of “confidential information”
- The purpose the information may be used for
- The term — how long confidentiality lasts
- Exclusions — public info, or what the receiver already knew
- Governing law and signature blocks
Is a unilateral NDA legally binding?
Yes — once both parties sign, a clear and reasonable one-way NDA is enforceable in most jurisdictions, and it usually doesn't need to be notarized. This is general information, not legal advice: for high-stakes or unusual deals, have a qualified lawyer review it.
