If you violate a non-disclosure agreement, you can be sued for breach of contract and ordered to pay the other party’s financial losses, hit with a court injunction stopping any further use of the information, and, when trade secrets are involved, prosecuted under federal criminal law with up to 10 years in prison on the table. The practical fallout usually includes losing your job and taking lasting damage to your professional reputation, whether or not a court ever enters a judgment.
How bad it gets depends on what you disclosed, who it reached, whether the information qualifies as a trade secret, and what your specific agreement says.
The First Move Is Usually a Letter, Not a Lawsuit
The other side typically opens with a cease and desist letter. It identifies what you allegedly disclosed, demands that you stop sharing anything further, and tells you to return or destroy any confidential materials in your possession. It almost always warns that a lawsuit will follow if you don’t comply. Many breaches end here, particularly when the disclosure was inadvertent and the information hasn’t spread.
If the letter doesn’t resolve the problem, or if real harm has already occurred, the other party can file a breach of contract lawsuit. NDA litigation is expensive on both sides. Business litigation attorneys commonly charge $300 to $400 per hour, and cases that go to trial can run for months or years. Court filing fees alone range from roughly $50 to $400 depending on jurisdiction and the amount in dispute.
Money You Could Owe
The primary remedy in a successful breach of contract claim is compensatory damages: the amount needed to put the other party back where they would have been without the breach. If a competitor gained access to proprietary information and took market share, you would owe the lost profits. If the disclosure forced the company to accelerate a product launch or rebrand, those costs get added. The hard part for the party suing is proving the dollar figure and tying it directly to what you disclosed.
Many NDAs skip that proof problem with a liquidated damages clause, which sets a specific dollar amount or formula triggered by any breach. These clauses are enforceable, but not automatically. A court will refuse to enforce an amount that functions as a penalty rather than a reasonable estimate of likely harm. A clause setting damages at $5 million when the realistic harm is $50,000 can be thrown out entirely.
Punitive damages come up often in NDA discussions and are worth demystifying. Most jurisdictions will not award them for a straightforward breach of contract. You generally need fraud, intentional interference with a business relationship, or some other independent wrongful act layered on top of the breach itself. For an ordinary NDA violation, damages are almost always limited to actual financial harm.
Enhanced Remedies for Trade Secrets
If the confidential information qualifies as a trade secret, the Defend Trade Secrets Act gives the other party a separate set of civil remedies on top of contract damages. A court can award actual losses plus any unjust enrichment the breaching party gained, or alternatively impose a reasonable royalty for the unauthorized use.1Office of the Law Revision Counsel. 18 USC 1836 – Civil Proceedings If the misappropriation was willful and malicious, the court can double those damages. The prevailing party can also recover attorney’s fees in cases involving bad faith or willful misappropriation.
Court Orders That Stop You From Doing Anything Else
Money compensates for harm already done. Injunctions prevent future harm, and courts frequently grant them in NDA cases because once a secret is out, money alone can’t put it back. A temporary restraining order can come within days of filing. A preliminary or permanent injunction can follow, requiring you to stop all further disclosure or use of the protected information.
The party suing generally needs to show irreparable harm, meaning harm money can’t fix. Many NDAs include a clause stating that any breach causes irreparable injury, which makes injunctive relief easier to obtain. Under the Defend Trade Secrets Act, courts can issue injunctions against actual or threatened misappropriation, though they cannot bar you from taking a new job based solely on what you know.1Office of the Law Revision Counsel. 18 USC 1836 – Civil Proceedings
When an NDA Violation Becomes a Crime
Most NDA violations stay civil. The exception is trade secret theft committed for economic advantage, which is a federal crime.
Under the Economic Espionage Act, stealing or misappropriating a trade secret for the economic benefit of anyone other than the owner carries up to 10 years in prison, a fine, or both.2Office of the Law Revision Counsel. 18 US Code 1832 – Theft of Trade Secrets Organizations convicted of the same offense face fines up to the greater of $5 million or three times the value of the stolen trade secret. If the theft benefited a foreign government, agent, or entity, the ceiling rises to 15 years in prison and fines up to $10 million or three times the stolen value for organizations.3Office of the Law Revision Counsel. 18 US Code 1831 – Economic Espionage
You don’t have to steal anything in the physical sense. Copying files, downloading data, or passing information along verbally all qualify if done knowingly and for economic benefit. Attempt and conspiracy carry the same penalties as a completed offense.2Office of the Law Revision Counsel. 18 US Code 1832 – Theft of Trade Secrets
The Career Consequences Often Outlast the Legal Ones
For an employee, breaching a confidentiality agreement is almost always grounds for immediate termination. Beyond losing your current job, a known breach marks you as a liability to future employers. In tech, finance, pharmaceuticals, and law, the same people circulate among a limited set of companies and word travels. Hiring managers check references and run background searches, and a breach of contract lawsuit on your record raises obvious questions about whether you’ll protect the next employer’s information.
The informal fallout can be worse than the formal one. Professional networks close off and referrals dry up. In specialized fields, a reputation for breaking confidentiality can effectively end a career path even if no court ever enters a judgment.
When the Claim Against You May Fail
Not every NDA breach claim succeeds, and some NDAs turn out to be unenforceable on their face.
The NDA Is Overbroad or Unreasonable
Courts can refuse to enforce an NDA that sweeps too broadly in scope, duration, or definition. An agreement defining “confidential information” to include publicly available facts, or imposing lifetime restrictions on information with a short commercial life, risks being struck down. Several jurisdictions apply the same reasonableness analysis used for non-compete agreements, asking whether the restrictions match what the company legitimately needs to protect. If the company itself treated the information carelessly, sharing it widely without labeling it confidential or without restricting access, the agreement may fail on that ground too.
The Information Wasn’t Really Confidential
The most common factual defense is that what you shared doesn’t qualify as confidential under the agreement. Most NDAs exclude information that was already publicly available, that you already knew before signing, or that you developed independently. If you can show you reached the same information through your own work, that is generally a complete defense. Independent development after the fact is harder to prove than prior knowledge, so documentation matters.
The Disclosure Was Authorized or Legally Compelled
If the NDA permits certain disclosures, such as to attorneys, accountants, or employees who need to know, sharing within those limits isn’t a breach. Complying with a subpoena or court order is also not a breach. Most well-drafted NDAs include a carve-out for legally compelled disclosures, though they usually require you to notify the other party first so they can seek a protective order.
You Were Reporting Illegal Conduct
Federal law blocks NDAs from being used to silence people reporting wrongdoing. Under the Defend Trade Secrets Act, you cannot be held criminally or civilly liable under any federal or state trade secret law for disclosing a trade secret in confidence to a government official or an attorney solely to report a suspected violation of law, or when you include it in a sealed court filing.4Office of the Law Revision Counsel. 18 USC 1833 – Exception to Prohibitions If you file a retaliation suit against an employer for reporting suspected illegal conduct, you can share the trade secret with your attorney and use it in the proceeding, as long as relevant documents are filed under seal. The protection extends to contractors and consultants, not just employees.
Separately, no person may take any action to stop someone from communicating with SEC staff about a possible securities law violation, including by enforcing or threatening to enforce a confidentiality agreement, under Commission Rule 21F-17(a).5Securities and Exchange Commission. Whistleblower Protections The SEC has brought enforcement actions against companies whose contracts or severance agreements required prior approval before contacting regulators or waived rights to whistleblower awards. Those provisions are illegal, not just unenforceable.
What to Do If You’ve Already Breached
If you’ve realized you disclosed something you shouldn’t have, acting quickly limits both the legal and the practical damage. The instinct to pretend it didn’t happen is understandable and counterproductive. Courts weigh whether you took steps to mitigate harm, and doing nothing makes everything worse.
Call an attorney who handles contract or trade secret disputes before you contact the other party. You need to understand your exposure and what the NDA actually requires, because some agreements have specific notification procedures for inadvertent disclosures. Once you have advice, the typical steps are stopping any further disclosure immediately, trying to retrieve or contain what you shared, and documenting what you did and when. If the person who received the information hasn’t acted on it yet, early intervention can sometimes keep the matter out of court entirely.
One timing point worth knowing: statutes of limitations for breach of a written contract vary by state, typically three to six years, with the clock usually starting when the breach happens or when the other party discovers it. That window matters whether you’re the one who breached or the one weighing legal action.
