How do I know if an NDA definition is too vague?

An NDA is likely unenforceable if it uses 'catch-all' language that fails to distinguish between general employee knowledge and proprietary trade secrets, effectively preventing an employee from using their professional skills elsewhere.

What makes an NDA definition legally unenforceable?

Lack of specificity, overbreadth, and the inclusion of publicly available information are the primary factors that render an NDA definition legally unenforceable in most jurisdictions.

How to determine if an employment NDA definition of confidential information is too vague to be enforceable?

How to determine if an employment NDA definition of confidential information is too vague to be enforceable

An NDA definition is legally unenforceable if it fails to distinguish between proprietary trade secrets and an employee’s general professional knowledge. If the definition is so broad that it prevents an individual from using their standard skills or experience in future employment, courts will likely strike it down as an unreasonable restraint of trade.

The Legal Standard for Specificity

Courts evaluate the enforceability of an NDA based on the 'reasonableness' test. A definition of confidential information must be narrow enough to protect a legitimate business interest but broad enough to cover actual assets. If the definition is a 'catch-all' that includes everything an employee learns during their tenure, it is inherently defective.

Red Flags of Vague Definitions

All-encompassing language: Phrases like 'any and all information learned during employment' are almost always unenforceable.
Lack of categorization: Failure to specify what constitutes a trade secret (e.g., source code, client lists, internal pricing models).
Public domain inclusion: Clauses that attempt to restrict information already available to the public or industry standard knowledge.
No temporal limitation: Definitions that imply confidentiality lasts indefinitely without regard to the information's actual shelf life.

Key takeaway: If you cannot identify exactly what information is protected by reading the contract, a judge will likely find the definition void for vagueness.

Action Item: Audit your NDA for a 'carve-out' section. If the contract lacks a clear list of what is not confidential, it is likely too vague.

Comparing Enforceable vs. Unenforceable Definitions

Feature	Unenforceable Definition	Enforceable Definition
Scope	Everything learned at the company	Specific trade secrets and proprietary data
Public Info	Includes public knowledge	Explicitly excludes public information
Skill Usage	Restricts general job skills	Allows use of general professional knowledge
Clarity	Vague, catch-all phrases	Defined categories with examples

Jurisdictional Nuances and Trends

Enforceability varies significantly by state. For instance, California (Business and Professions Code Section 16600) maintains a very strict stance against non-competes and overly broad NDAs that function as non-competes. In contrast, states like Delaware or New York may allow for broader definitions, provided they are tied to specific, protectable business interests.

The 'General Knowledge' Doctrine

Courts consistently rule that an employee cannot be prevented from using their 'general knowledge, skill, and experience' acquired during their career. If an NDA definition attempts to classify the employee's own professional development as 'confidential company information,' it is unenforceable as a matter of public policy.

Action Item: Check the governing law clause in your contract. If you are in a state with strong employee protections, focus your challenge on the 'restraint of trade' aspect of the vague definition.

Steps to Evaluate Your NDA

Identify the 'Confidential Information' section: Locate the specific paragraph defining the scope of protected data.
Test for 'Catch-All' language: Highlight any phrases like 'including but not limited to all information...' and evaluate if they lack specific examples.
Check for Exclusions: Ensure the contract explicitly excludes information that is publicly known, independently developed, or received from third parties.
Assess the 'Reasonable' Test: Ask if the definition prevents you from performing your job duties at a future employer. If the answer is yes, the definition is likely overbroad.

Key takeaway: A well-drafted NDA should provide a 'safe harbor' for information that is not proprietary, ensuring the employee understands exactly what they are prohibited from disclosing.

Action Item: Create a list of the top three types of information you handle that are truly proprietary. If your NDA definition does not cover these specifically, it is either too vague or poorly targeted.
