If one of the contracting parties breaches the non-disclosure agreement, claims for damages and injunctive relief arise at the expense of the infringer, but these do not represent a negligible risk. On the one hand, the burden of presentation and proof lies with the infringed party, which makes it considerably more difficult to enforce the claims. On the other hand, it is also difficult for the opposing party to estimate exactly what claims for damages they will face because the amount is usually difficult to calculate.
It therefore often makes sense to contractually regulate the consequences of possible infringements in order to avoid later conflicts. For example, relatively low-threshold regulations on the burden of proof or the determination of a lump sum compensation for damages.
It is also possible to stipulate a contractual penalty for breaches of the NDA. However, it should be noted that if the confidentiality agreement is structured as a GTC, the provisions of GTC law apply, which may prevent it from being effective. Particularly in the case of unilateral NDAs, high demands are placed on proportionality and transparency, which is why the amount and conditions of the contractual penalty should be differentiated depending on the type, scope and severity of the breach (for example, whether the NDA was breached intentionally or only negligently).
