A non-disclosure agreement is a unilateral commitment to confidentiality — unlike a mutual NDA. Form: one party receives confidential information and agrees to keep it secret. Common in investor pitches, freelance access to client data, and pre-employment for job applicants. Advantages: simpler, faster to sign. Disadvantages: unequal power dynamic, can seem unattractive. Below are the differences compared to an NDA and when to use which form.

The short answer

  • Unilateral: only the recipient is obliged to maintain confidentiality.
  • When: investor info, freelancers, applicants, suppliers.
  • Difference between NDAs: NDAs are mutual, non-disclosure agreements are unilateral.
  • Duration: typically 2-5 years after receipt of information.
  • Content: similar to an NDA, but formulated unilaterally.

When to Use a Non-Disclosure Agreement vs. an NDA?

Confidentiality agreement with signature

Confidentiality Agreement (unilateral)

  • The investor receives your business case.
  • Freelancer gains access to customer data.
  • Applicant gains access to trade secrets during the process.
  • Supplier receives specifications.
  • Intern or student on a company visit.

NDA (mutual)

  • Strategic cooperation — both parts info.
  • Joint venture negotiations.
  • M&A discussions between buyer and seller.
  • Co-development project.

What is typically included?

  1. Identification of signatory: name, position, company.
  2. Identification of information provider: company from which information originates.
  3. Description of confidential information: technical, commercial, strategic.
  4. Purpose of provision: for what purposes information may be used.
  5. Obligation of confidentiality: do not share, do not use for other purposes.
  6. Exceptions: already publicly known, previously known, independently developed.
  7. Duration: typically 2-5 years after receipt.
  8. Return: or destruction after use.
  9. Penalty for violation: contractual amount.
  10. Applicable law and court.

Practical examples

Applicant confidentiality agreement

Applicants who are granted access to company strategy during the process: sign a unilateral declaration in advance. Short, simple (1-2 pages).

Freelance access

Freelancer gains access to client systems for a specific project — non-disclosure agreement protects client data. Often combined with IP transfer.

Investor pitch

Before sharing the pitch deck: the investor signs a unilateral declaration. Some top-tier investors refuse to sign (market standard) — if in doubt: a shorter/more focused pitch without critical information.

Fine level

For a unilateral declaration:

  • Applicants: €10,000-€25,000 (proportional).
  • Freelancers: €25,000-€50,000 (depending on data sensitivity).
  • Investors/business partners: €50,000-€250,000 (strategic info).

Higher than realistic: judge reduces.

Honest recommendation

Legal expert reviews confidentiality agreement

Non-disclosure agreement for standard situations with an asymmetrical relationship (you provide, the other party receives). NDA for strategic cooperation. Have a one-time template drafted by a lawyer (€200-€500) — then use it for years to come. For sensitive information or major partners: consider a custom solution. Ensure proper documentation (which information is provided to whom and when) — indispensable in the event of a dispute.

For other topics: NDA, non-compete clause and copyright protection.

Frequently Asked Questions

Difference with NDA?

A non-disclosure agreement is unilateral (only the recipient is required), while an NDA is mutual (both parties). Agreement for asymmetric situations (investors, freelancers, job applicants); NDA for strategic cooperation with reciprocal information exchange.

When which form?

Explanation: investor info, freelance access, applicants, suppliers. NDA: joint ventures, M&A, co-development. In case of doubt: NDA — demonstrates an equivalent position and is more robust.

How high is the fine?

Applicants €10,000-€25,000, freelancers €25,000-€50,000, investors/business partners €50,000-€250,000 (depending on data sensitivity). Realistic amount for enforceability — judge may reduce unsustainable fines.

What needs to go in it?

Identification of signatory and provider, description of confidential information, purpose of provision, confidentiality obligation, exceptions, duration (2-5 years), return/destruction, penalty, applicable law.

How long is it valid?

Typically 2-5 years after receipt of information. For strategic info (M&A, IP): 5+ years. Indefinite period often unsustainable. Concrete end date essential for enforceability.

What if the investor refuses to sign?

Top-tier VCs often decline — unattractive and high-risk for them. If declined: shorter pitch without critical info, first a market-standard high-level pitch, sensitive details only at due date with a signed declaration.

How much does it cost?

Standard template from a lawyer: €200-€500. Customization: €500-€1,500. More for sensitive information or international aspects. One-time setup, usable for years — the investment pays for itself quickly.
