Breaking a non-disclosure agreement can trigger a civil lawsuit, a court order forcing the disclosure to stop, and a damages bill that may include the other side’s lost profits, the breacher’s own gains, and up to double that amount if the breach was deliberate. When the breach involves stolen trade secrets handed to a competitor, federal prosecutors can bring criminal charges carrying up to ten years in prison. What actually happens if someone breaks an NDA depends on what was disclosed, who it went to, and whether the agreement is enforceable in the first place.
The Civil Lawsuit and a Court Order to Stop
The most common response to a breach is a civil suit for breach of contract, often paired with a trade secret misappropriation claim under the federal Defend Trade Secrets Act. The first thing the court can do is issue an injunction: an order requiring the breaching party to stop any actual or threatened misappropriation and, if needed, to return or destroy the confidential materials.1Office of the Law Revision Counsel. 18 USC 1836
An injunction is often the most valuable remedy, because once a trade secret spreads it cannot be made secret again. There are limits, though. A court cannot use an injunction simply to block someone from taking a new job. Any restriction on future employment has to rest on evidence of an actual threat of misappropriation, not just the fact that the person carries confidential knowledge in their head.1Office of the Law Revision Counsel. 18 USC 1836 The injunction also cannot conflict with state laws limiting non-compete agreements. Where an outright ban on using the information would be unfair but the information still needs protection, the court can order the breacher to pay an ongoing royalty instead.
Money the Breacher Can Be Ordered to Pay
Financial exposure in an NDA case is built in layers, and the layers stack.
- Actual loss. The provable financial harm the disclosure caused, including lost profits, diminished business value, and the cost of containing the leak.
- Unjust enrichment. On top of actual loss, the court can award the profits or cost savings the breacher gained from using the information, as long as those gains aren’t already counted in the actual-loss figure.1Office of the Law Revision Counsel. 18 USC 1836
- Reasonable royalty. When neither of the above can be clearly proven, the court can impose a royalty based on what a willing buyer and seller would have agreed to in a license. This keeps the breacher from paying nothing just because the harm is hard to quantify.1Office of the Law Revision Counsel. 18 USC 1836
- Exemplary damages. If the misappropriation was willful and malicious, the court can tack on up to twice the compensatory award as a punitive layer.1Office of the Law Revision Counsel. 18 USC 1836
- Attorney fees. The prevailing party can recover reasonable attorney fees when the misappropriation was willful and malicious, or when the other side brought or defended the claim in bad faith.1Office of the Law Revision Counsel. 18 USC 1836
Many NDAs also carry a liquidated damages clause: a pre-agreed dollar figure the breacher owes automatically. These clauses are generally enforceable as long as the amount is a reasonable estimate of anticipated harm rather than a penalty, and they spare the injured party from having to prove exact losses.
When Trade Secret Theft Becomes a Federal Crime
Most NDA disputes stay in civil court. But when the breach involves deliberate theft of a trade secret for economic gain, the Economic Espionage Act kicks in. Stealing a trade secret connected to a product or service in interstate commerce is a federal crime punishable by up to ten years in prison, a fine, or both. Organizations face fines of up to $5 million or three times the value of the stolen secret, whichever is greater.2Office of the Law Revision Counsel. 18 US Code 1832 – Theft of Trade Secrets
Criminal charges are reserved for the worst cases: corporate espionage, intent to benefit a competitor, large-scale data theft. Someone who mentions a few details at a dinner party will not draw a federal indictment. Someone who copies proprietary files on the way out the door and hands them to a new employer has crossed from civil liability into potential felony territory.
Career and Professional Fallout
The courtroom isn’t where the consequences end. People who break NDAs commonly face immediate termination, loss of contracts, and forfeiture of unvested equity or deferred compensation. In tight-knit industries like finance, technology, and pharmaceuticals, the informal reputational damage can be worse than the legal judgment, making comparable work in the same field hard to find.
Defenses That Can Defeat the Claim
Being sued for breaching an NDA doesn’t automatically mean losing. Several defenses can knock out the claim entirely or shrink it dramatically.
The Information Didn’t Qualify for Protection
For a trade secret claim, the information has to meet a federal statutory definition: it must have independent economic value from not being generally known, and the owner must have taken reasonable measures to keep it secret.3Office of the Law Revision Counsel. 18 US Code 1839 – Definitions That second piece trips up many companies. If “confidential” files sat on an unsecured shared drive, documents went unmarked, or the information was openly discussed in public settings, a court may rule the material wasn’t a trade secret at all, no matter what the NDA calls it.
The Agreement Itself Is Unenforceable
Courts can refuse to enforce NDAs that sweep too broadly, run for an indefinite period, or define “confidential” so vaguely that the signer couldn’t reasonably know what was off-limits. An agreement that tries to prevent someone from ever using general skills or industry knowledge is a classic example of overreach. An NDA signed under duress, or with no consideration exchanged, is also vulnerable.
Independent Development or Public Information
If the accused can show they developed the information on their own, got it from a third party with no confidentiality duty, or that it reached the public through no fault of theirs, the breach claim collapses. Most well-drafted NDAs list these carve-outs explicitly.
When the NDA Can’t Be Used Against You at All
Some disclosures look like breaches but legally are not, and NDAs cannot be enforced to punish them. Anyone deciding whether to speak up needs to know where those lines fall.
Reporting suspected illegal activity. The Defend Trade Secrets Act grants immunity from criminal and civil liability for disclosing a trade secret in confidence to a government official or attorney solely to report or investigate a suspected legal violation, and for disclosures made in sealed court filings. If an employer retaliates, the employee can share the trade secret with their lawyer and use it in the retaliation suit, provided any documents containing it are filed under seal.4Office of the Law Revision Counsel. 18 USC 1833 – Exceptions to Prohibitions
Talking to the SEC. SEC Rule 21F-17(a) prohibits any person from taking any action to impede someone from communicating directly with SEC staff about a possible securities law violation, including enforcing or threatening to enforce a confidentiality agreement. The rule reaches further than many realize: even agreement language that merely places limits on how someone can report can trigger a violation, and SEC enforcement activity in this area accelerated through 2024 and 2025.5U.S. Securities and Exchange Commission.

Sexual assault and harassment claims. Since December 2022, the Speak Out Act has blocked enforcement of pre-dispute NDAs to silence claims of sexual assault or sexual harassment involving alleged violations of federal, state, or tribal law. An NDA signed at the start of a job cannot later gag a harassment claim. A settlement agreement negotiated after an incident, with confidentiality bargained for as part of the resolution, can still be enforceable. The Act doesn’t override trade secret protections, so restrictions on proprietary business information in the same agreement remain in force.6Congress.gov.

How Long the Other Side Has to Sue
Under the Defend Trade Secrets Act, a civil suit has to be filed within three years of the date the misappropriation was discovered or should have been discovered through reasonable diligence.1Office of the Law Revision Counsel. 18 USC 1836 A continuing misappropriation counts as a single claim, so the clock doesn’t reset each time the breacher uses the stolen information. State-law limitations for breach of contract vary but typically run three to six years. Once the deadline passes, the right to sue is gone.
