ClauseryMutual vs one-way NDA: which one do you need?
The only question that matters is who will share confidential information. If just one side shares, a one-way NDA is enough. If both sides share, use a mutual NDA.
The short answer
| Situation | Use |
|---|---|
| Partnership or joint venture talks | Mutual NDA |
| Evaluating a supplier or software vendor who will also see your data | Mutual NDA |
| Showing a prototype, pitching an idea or briefing an agency | One-way NDA |
| Hiring a freelancer or contractor | Contractor NDA (one-way) |
| Hiring an employee | Employee NDA (one-way) |
| Selling a business to a buyer who wants to see the books | NDA for selling a business (one-way) |
What actually changes between the two
- Who is protected. A one-way NDA names a disclosing party and a receiving party. A mutual NDA makes each party both, so every duty applies in both directions.
- How it reads to the other side. A mutual NDA looks balanced, which often makes it quicker to sign. Sending a one-way NDA when both sides will share can start the talks with an argument.
- What stays the same. The definition of confidential information, the exclusions, the term, return of information and governing law work the same way in both.
When a mutual NDA is the safer choice
If you are not sure whether the other side will share anything, use a mutual NDA. It costs you nothing if they never do, and it protects you if a conversation that started one-way turns into a real exchange of plans or data.
Three special cases
- Employees. An employee NDA is one-way, but it needs more than a standard one-way NDA: wording that it does not stop reporting to regulators, and in the US the Defend Trade Secrets Act notice. The employee NDA template includes both.
- Freelancers. A contractor NDA should limit use to the project, say whether subcontractors are allowed, and settle portfolio rights. Freelancers asked to sign a client's NDA can send the contractor NDA back as a fairer starting point.
- Investors. Many investors will not sign an NDA before a first meeting, because they see similar ideas every week. Share the pitch without the secrets, and use an NDA later, for due diligence.
