What is the primary risk of an NDA without an expiration date?

The primary risk is perpetual liability. Without a sunset clause, you remain legally bound to protect information indefinitely, even if that information becomes public knowledge, obsolete, or irrelevant to your current business operations.

Are perpetual NDAs enforceable in all jurisdictions?

Enforceability varies significantly. While some jurisdictions like California disfavor perpetual restraints, others, such as Delaware or New York, may enforce them if the scope is narrowly defined, though courts often prefer reasonable time limits.

How can I mitigate the risk of an indefinite NDA?

Always negotiate for a specific term (typically 2 to 5 years), include a 'carve-out' for information that becomes public, and ensure the agreement terminates automatically upon the conclusion of the business relationship.

A TermScore is an AI-generated risk rating from 0 to 100 that evaluates the fairness and risk level of any legal document. A score of 86-100 means the contract is highly favorable, while 0-30 indicates dangerous terms you should walk away from.

What types of documents can TermScore analyze?

TermScore analyzes any legal document including freelance contracts, employment agreements, residential leases, NDAs, brand sponsorship deals, SaaS vendor agreements, and rental applications. Upload PDFs, Word documents, or images.

How much does TermScore cost?

TermScore offers a free plan with 3 scores per month. The Team plan is $15/month for 30 scores, and the Professional plan is $50/month for 500 scores with team collaboration features.

Is my document data secure?

Yes. Documents are processed in memory and analysis results are stored encrypted. TermScore never shares your document data with third parties and you can delete your data at any time from your dashboard.

What are the legal risks of signing an NDA that lacks a specific expiration date?

Signing an NDA without an expiration date creates perpetual liability, forcing you to protect information indefinitely. This exposes your company to long-term litigation risks, administrative burdens, and potential breach-of-contract claims even decades after the underlying business relationship has ended.

The Dangers of Perpetual Confidentiality

An NDA without a sunset clause is a "perpetual" agreement. In the eyes of the law, this means your obligation to keep secrets never expires. This creates a "ticking time bomb" effect where your company remains liable for information that may have long since lost its competitive value.

Operational and Administrative Burdens

Data Management: You must maintain rigorous document retention policies for information that may no longer be relevant.
Employee Turnover: As employees leave, you remain responsible for their actions regarding the protected data, increasing your vicarious liability.
Audit Complexity: Proving compliance becomes exponentially harder as time passes and institutional knowledge fades.

Key takeaway: Perpetual NDAs are not just legal risks; they are operational liabilities that increase your cost of compliance every year the agreement remains active.

Action Item: Audit your current contract repository to identify any agreements lacking a "Term" or "Expiration" section. Flag these for immediate review.

Jurisdictional Enforceability and Judicial Scrutiny

Courts generally dislike perpetual restraints on trade or information. However, the level of scrutiny depends heavily on the governing law of the contract.

Jurisdiction	View on Perpetual NDAs
California	Highly skeptical; often viewed as an unreasonable restraint on trade.
Delaware	Generally enforces freedom of contract, but requires clear, unambiguous language.
New York	Enforceable if the scope is reasonable, though courts prefer defined timeframes.
Texas	Enforceable, but must be supported by legitimate business interests.

Why Courts May Strike Down Perpetual Clauses

If a dispute reaches litigation, a judge may invalidate a perpetual NDA if it is deemed "unreasonable." Factors include:

The nature of the information (e.g., trade secrets vs. general business knowledge).
The industry standard for confidentiality (e.g., tech vs. manufacturing).
Whether the restriction prevents an employee from earning a living.

Key takeaway: Do not rely on a court to "fix" a bad contract. If you sign a perpetual NDA, you are assuming the risk that a court will enforce it as written.

Action Item: When negotiating, cite industry standards. If the standard term in your sector is 3 years, use that as your baseline for negotiation.

Best Practices for Negotiating NDA Terms

To protect your interests, you must shift the burden of proof back to the disclosing party. Use these strategies to limit your exposure:

Define a Sunset Clause: Aim for a 2-year term for general information and a 5-year term for trade secrets.
Include Public Domain Carve-outs: Explicitly state that obligations end if the information becomes public through no fault of your own.
Termination Triggers: Link the expiration to the end of the business relationship or the completion of a specific project.
Return or Destroy Provisions: Require the return or destruction of data upon termination to effectively "close" the file.

The "Reasonable" Standard

When you push back on a perpetual NDA, frame your request as a matter of "reasonable business practice." Most sophisticated parties will accept a 3-to-5-year term because it aligns with the typical lifecycle of competitive information.

Key takeaway: Always negotiate for a "sunset" date. If the other party insists on perpetuity, demand that the definition of "Confidential Information" be narrowed significantly to only include actual trade secrets.

Action Item: Create a standard "NDA Playbook" for your team that mandates a maximum 3-year term for all incoming NDAs.
