Answer:
If someone breaches a non-disclosure agreement then they are in breach of a contract and are liable to pay damages in accordance with the breach. However, a non-disclosure agreement can include provisions that deal with the consequences of the recipient breaching the non-disclosure agreement.
In addition to damages for breach of the non-disclosure agreement, the discloser may also apply to the court for an injunction to prevent any further disclosure of confidential information. If you don’t have an actual non-disclosure agreement, a court is less likely to rule in your favour against the person who disclosed information, such as a trade secret. The more you use the law to protect your information, the more it will come to help you out if someone infringes upon those protections.
