Commercial Contracts with German Partners

Hidden Dangers: When Can Your Czech Contract Be Deemed Invalid?

Beyond disputes over specific clauses, German companies face the ultimate risk: having their entire contract declared invalid from the beginning (ab initio). This can happen in several ways, but two scenarios are particularly dangerous for foreign businesses.

First, relying on vague or overly broad Representations and Warranties can render them unenforceable. A recent Prague High Court ruling determined that general statements not linked to specific, verifiable obligations (e.g., "the company has no outstanding legal impediments") are too uncertain to support a claim for a contractual penalty. This highlights the danger of using boilerplate language from other jurisdictions.

Second, a critical compliance trap exists for companies working with public entities, such as municipalities, state-owned enterprises, or public institutions. Under Czech law, most contracts with such bodies must be published in the public Register of Contracts. If a contract is not published within three months of being signed, it is automatically considered invalid from the outset. It is treated as if it never existed.

If performance has already occurred under a contract later deemed invalid, you cannot sue for breach of contract. Instead, you are forced into a much more complex legal proceeding to recover your losses under the doctrine of "unjustified enrichment" (bezdůvodné obohacení). This shifts the burden of proof and creates significant uncertainty, turning a simple procedural oversight into a major financial and legal battle.
