What is Non-Disclosure Agreement (NDA)?
A legal contract in which parties agree to keep specified information confidential and not disclose it to third parties.
Definition
A Non-Disclosure Agreement (NDA) — also called a Confidentiality Agreement or Confidentiality Provision within a broader contract — is a legally binding agreement in which one or both parties commit to protecting specified confidential information received from the other party and to not disclosing it to unauthorized third parties. NDAs define what information is confidential, how it may and may not be used, how long the confidentiality obligation lasts, and what happens in the event of a breach.
One-Way vs. Two-Way NDAs
In a one-way NDA, only one party is sharing confidential information (typically the client sharing sensitive business information with the freelancer). In a two-way NDA, both parties are sharing confidential information with each other. For example, a freelancer may share proprietary methodologies or pricing information that the client agrees to keep confidential. Two-way NDAs are common in partnerships, joint ventures, and client relationships where both sides share sensitive information.
What NDAs Protect
NDAs in freelance contexts typically cover: trade secrets (formulas, processes, client lists, pricing), business strategies and financial information, product plans and roadmaps, technical specifications and source code, marketing plans and campaigns, and personal or employee data. NDAs generally do not protect information that is already public, information the freelancer already knew before the NDA was signed, or information the freelancer developed independently without using the client's confidential information.
NDAs from the Freelancer's Perspective
Freelancers should carefully review any NDA presented by a client before signing. Key things to check: the definition of confidential information — is it overly broad?; the duration of the NDA — is it reasonable (1–3 years is typical; perpetual obligations are questionable); exclusions — does it carve out information that becomes public through no fault of yours?; permitted disclosures — does it allow you to share with employees or subcontractors as needed?; and portfolio rights — can you show the work in your portfolio after the project ends?
Enforcing an NDA
If a party breaches an NDA, the other party can seek legal remedies including injunctive relief (a court order stopping further disclosure) and monetary damages (compensation for losses caused by the breach). Proving damages in an NDA breach can be difficult — the harm is often the loss of the confidentiality itself, not a quantifiable financial loss. The most effective remedy is often injunctive relief to stop ongoing disclosures. In practice, the threat of legal action is usually enough to encourage compliance.
