An Ohio non-disclosure agreement is enforceable when it rests on valid consideration, defines the confidential information with reasonable scope and duration, carves out the standard exclusions, and carries the federal whistleblower immunity notice required for any agreement signed by an employee or contractor. Ohio courts will enforce a well-drafted NDA under the Ohio Uniform Trade Secrets Act and standard contract principles, but they also scrutinize whether the restrictions are reasonable before signing off, and federal law imposes a separate drafting requirement that many Ohio businesses still miss.
What Makes an Ohio NDA Enforceable
Consideration
Every contract needs consideration. For a new hire, the job itself is the consideration. For an existing at-will employee asked to sign an NDA mid-employment, the Ohio Supreme Court held in Lake Land Employment Group of Akron, LLC v. Columber that continuing the employment relationship is itself sufficient consideration for a restrictive covenant, even without a raise, bonus, or promotion.1Supreme Court of Ohio. Lake Land Emp. Group of Akron, LLC v. Columber
That is the floor, not the ceiling. Pairing the NDA with a signing bonus or other tangible benefit makes the agreement harder to attack and signals good faith, but it is not legally required for an at-will worker.
Reasonable Scope
Ohio courts weigh three factors drawn from Raimonde v. Van Vlerah: the restriction must be no broader than necessary to protect a legitimate interest, it must not impose undue hardship on the restricted party, and it must not harm the public interest. An NDA that effectively locks someone out of their entire field, or that runs for decades without justification, is at risk.
Duration is where most agreements overreach. A two-year confidentiality period tied to specific competitive information will generally survive review. An indefinite restriction on vaguely defined “proprietary knowledge” often will not. Geographic limits matter less for pure confidentiality obligations than they do for non-competes, but courts still ask whether the scope matches the interest being protected.
If a Court Finds It Overbroad
Ohio judges have discretion under Raimonde to narrow an overbroad restriction rather than void it, trimming duration, geography, or activity to something reasonable. Appellate courts have confirmed this is discretionary, not guaranteed. Some judges will salvage the agreement; others will decline to rewrite what the parties should have drafted correctly. Drafting for judicial rescue is a bad plan.
What the NDA Must Define
Parties and Purpose
Identify the disclosing and receiving parties by their full legal names as they appear on official registrations. If one party is a business entity, use the entity name rather than the owner’s personal name unless the owner is personally bound. Then state the specific reason the information is being shared, whether that is a potential acquisition, an employment relationship, a vendor engagement, or a joint development project. A narrow purpose limits what the receiving party can do with the information and gives a court a clear frame for judging any breach.
Confidential Information
The agreement must say what is confidential. Some NDAs pair broad categories with specific examples. Others require the disclosing party to mark documents as confidential at the moment of disclosure. The Ohio Attorney General’s own template requires that confidential information be “clearly identified as Confidential Information at the time of its disclosure,” and that oral disclosures be reduced to writing within 30 days.2Ohio Attorney General. OBR Non-Disclosure Agreement
Specificity protects both sides. The discloser avoids arguments about whether a given document was really meant to be confidential, and the recipient avoids tripping over obligations they did not know applied.
Keep in mind what the information must look like to earn trade secret protection under Ohio Revised Code 1333.61: it has to derive economic value from being kept secret, and the owner has to take reasonable steps to keep it so. The statute covers technical material like formulas, designs, processes, and software, along with business material like financial records, marketing plans, and customer lists.3Ohio Legislative Service Commission. Ohio Code 1333.61 – Uniform Trade Secrets Act Definitions An employee’s general skills and know-how do not qualify, so the NDA cannot stop someone from using what they learned on the job in a general sense.
Standard Exclusions
Every well-drafted NDA carves out categories of information that do not count as confidential even if they technically fall within the defined scope:
- Information already in the public domain, or that later becomes public through no fault of the receiving party.
- Information the receiving party can prove it already knew before the NDA was signed.
- Information the receiving party developed independently without reference to what was disclosed.
- Information received from a third party who had the legal right to share it.
The Ohio Attorney General’s sample NDA includes these exclusions.2Ohio Attorney General. OBR Non-Disclosure Agreement An NDA that omits them tends to read as unreasonable on its face.
Duration
Set a clear start date and a clear confidentiality period. The right length depends on the information. Technical secrets in fast-moving industries might warrant two to three years. A manufacturing formula with a long competitive life could justify five or more. Indefinite terms are not automatically invalid, but they draw heavier scrutiny and are more likely to be narrowed or rejected.
Return or Destruction of Materials
Say what happens to confidential materials when the relationship ends. A sound clause requires the receiving party to return all copies or destroy them and certify the destruction in writing. The obligation should reach notes, analyses, and derivative work, not just original documents. Most agreements also allow retention of copies required by law or captured in routine electronic backups, provided those copies remain subject to the NDA’s confidentiality terms.
The Federal Whistleblower Notice You Can’t Skip
The federal Defend Trade Secrets Act requires every NDA or similar agreement with an employee or contractor to include a notice of whistleblower immunity. The notice must inform the individual that they cannot be held criminally or civilly liable for disclosing a trade secret in confidence to a federal, state, or local government official, or to an attorney, for the purpose of reporting a suspected legal violation, or for filing a trade secret under seal in a lawsuit.4Office of the Law Revision Counsel. 18 USC 1833 – Exceptions to Prohibitions
Skipping the notice does not void the NDA. The consequence is narrower and arguably worse: the employer loses the right to recover exemplary damages or attorney fees in any federal trade secret action against that employee. Those remedies can run into six figures, so leaving out one paragraph can cost an employer a great deal in a later lawsuit.4Office of the Law Revision Counsel. 18 USC 1833 – Exceptions to Prohibitions
Employers do not have to paste the full statutory language into the NDA. A cross-reference to a company policy document that explains the whistleblower reporting process satisfies the requirement.4Office of the Law Revision Counsel. 18 USC 1833 – Exceptions to Prohibitions The requirement applies to agreements entered into or updated after May 11, 2016, and reaches both employees and independent contractors.
Unilateral or Mutual
Match the structure to the direction information actually flows.
A unilateral NDA binds only the receiving party, which fits the typical employer-employee relationship, an investor pitch, or a vendor onboarding where the business shares proprietary data but gets none back. A mutual NDA binds both sides and fits joint ventures, merger talks, and technology collaborations where each party puts proprietary material on the table. Using a mutual NDA where a one-way agreement would do creates needless complexity about who owes what. Using a one-way NDA in a genuinely two-way exchange leaves one side’s information exposed.
Signing and Keeping the Record
Ohio recognizes electronic signatures under its Uniform Electronic Transactions Act, which gives e-signatures the same legal standing as handwritten ones when both parties intend to sign and to transact electronically.5Ohio Legislative Service Commission. Ohio Code Chapter 1306 – Uniform Electronic Transactions Act A digital signing platform or ink on paper both work; the key is clear intent to be bound.
Ohio law does not require witnesses or notarization for an NDA to be valid. For high-value agreements, or where the parties have little history together, notarization is cheap authentication and can head off later disputes about whether a signature is genuine.
Each party should keep a fully executed copy in a secure, accessible system. Record when the agreement was signed and when each party received its copy. In litigation, the ability to prove exactly when confidentiality obligations started often decides whether a particular disclosure counts as a breach.
What You Can Recover If It’s Breached
Injunctive Relief
The fastest remedy is a court order stopping the misuse. Ohio law allows an injunction against actual or threatened misappropriation, which remains in place as long as the trade secret keeps its status. Even after a secret becomes public, a court may extend the injunction if lifting it would hand the wrongdoer a lasting commercial advantage.6Ohio Legislative Service Commission. Ohio Code 1333.62 – Injunction Against Misappropriation In exceptional cases a court can also order affirmative protective steps, such as returning materials or segregating data inside the receiving party’s systems.
Damages
Ohio allows recovery of actual losses caused by the misappropriation plus any unjust enrichment not captured in that loss calculation. As an alternative, the court can impose a reasonable royalty for the unauthorized use. If the misappropriation was willful and malicious, the court can add exemplary damages of up to three times the base award.7Ohio Legislative Service Commission. Ohio Code 1333.63 – Damages Recoverable Attorney fees are available on the same willful-and-malicious standard, or when a claim is brought or resisted in bad faith.8Ohio Legislative Service Commission. Ohio Code 1333.64 – Attorney Fees
The Federal Option
Ohio businesses can also sue under the federal Defend Trade Secrets Act, which provides its own injunctive relief, actual damages, unjust enrichment, and reasonable royalty. The federal exemplary damages cap is two times the base award for willful and malicious misappropriation, lower than Ohio’s three-times multiplier.9Office of the Law Revision Counsel. 18 USC 1836 – Civil Proceedings The DTSA gives an independent federal cause of action, so a plaintiff can file in federal court without diversity jurisdiction. Many Ohio trade secret cases plead both state and federal claims.
Deadline to Sue
An Ohio trade secret misappropriation claim must be filed within four years after the misappropriation is discovered or reasonably should have been discovered.10Ohio Legislative Service Commission. Ohio Code Title 13 Chapter 1333 Section 1333.66 – Time for Commencing Action The clock does not start on the date of the breach itself if the owner had no way to know. Sitting on suspicious activity after you spot it will still kill the claim.
A Note on Inevitable Disclosure
Ohio recognizes the inevitable disclosure doctrine, which lets an employer seek an injunction preventing a former employee from taking a new role where they would inevitably use or reveal trade secrets from the old one. It can apply without an NDA, but a well-drafted NDA that clearly identifies the protected information makes the claim far easier to pursue, which is one more reason to get the definitions right the first time.
