How Luxembourg Firms Can Improve Commercial Agreements with Czech Partners

The principle of good faith ( poctivost and dobrá víra ), while present in both legal systems, operates robustly in Czech practice. Czech law imposes an implied duty of good faith in all legal dealings. This means a Czech court may assess whether a party acted fairly and honestly, potentially overriding a strict literal interpretation if it leads to a manifest injustice. For Luxembourg companies accustomed to a formalistic approach, this creates a need to document not just the what of a contract, but the why —the commercial intent.

The most dangerous clause: understanding the smluvní pokuta

Of all the legal traps awaiting Luxembourg companies in the Czech Republic, the most financially dangerous is the misunderstanding of the contractual penalty known as the smluvní pokuta. This powerful legal instrument functions differently than penalty clauses in many Western jurisdictions and can transform a minor contractual breach into a major financial liability. Assuming it functions exactly like a Luxembourg penalty clause is a mistake that can cost your company dearly.

Czech law, by contrast, treats the smluvní pokuta as a fully enforceable mechanism for securing contractual performance (utvrzení dluhu), regardless of whether the creditor suffered actual financial damage from the breach. The Czech Civil Code explicitly permits penalties to be applied to any contractual breach, including purely monetary ones such as late payment.

Consider a concrete scenario: a Luxembourg software company signs a contract with a Czech buyer. The contract contains a smluvní pokuta clause stipulating a penalty of 0.1% of the total contract value for each day of delay in delivery or payment. While this percentage seems small, it equates to 36.5% annually. A delay of two months would trigger a penalty equivalent to roughly 6% of the entire deal value, often exceeding the profit margin.

The critical distinction is that the smluvní pokuta is primarily punitive and preventative in nature, not merely compensatory. This means the penalty is enforceable even if the Czech creditor suffered no actual financial damage from the breach. The mere fact of the breach is sufficient to trigger the full penalty. Furthermore, unless explicitly agreed otherwise, payment of the contractual penalty does not release the debtor from the obligation to perform the primary duty.

While Czech courts do retain the authority to moderate a penalty that is deemed "unreasonably high" (nepřiměřeně vysoká), this requires initiating expensive litigation and the burden of proof lies with the debtor. There is no mathematical certainty where "unreasonable" begins; while 0.5% daily might be struck down, 0.05% or 0.1% daily is often enforced.

The formal requirements trap: when verbal agreements don't work

While business culture often relies on trust and verbal agreements, Czech law imposes strict formal requirements for certain types of contracts. Failure to comply can render an agreement invalid or unenforceable. This procedural requirement catches many Luxembourg companies off guard, particularly when they attempt to establish informal business relationships with Czech partners.

For certain categories of agreements, Czech law requires written form as a condition of legal validity (ad validitatem). Examples include contracts involving the transfer of real estate, certain license agreements, and specific commercial agency arrangements depending on the scope. Furthermore, if the parties stipulate that they require a written form for their agreement, then a verbal modification is ineffective.

The implications extend beyond specific statutory types. Any contract that is not properly documented, with clear and complete identification of the parties (including Company ID/IČO and registered seat), can face significant challenges during enforcement. Simply stating that "we have a relationship" or "we agreed verbally" is risky.

This creates a critical asymmetry in dispute resolution. If your Czech partner breaches a verbal agreement, you may struggle to prove the agreed terms (e.g., the exact price, delivery date, or quality standards). Conversely, if you breach what both parties understood as a verbal arrangement, your partner might present fragmentary written evidence that a court might construct into a binding contract.

The practical consequence is clear: relying on informal understandings is not a viable business strategy in the Czech Republic. ARROWS Law Firm advises Luxembourg companies to ensure all agreements with Czech partners are properly documented from the outset.

Running out of time: the statute of limitations trap

One of the most insidious risks in cross-border commerce is the silent expiration of legal rights. A Luxembourg company, operating under the assumption that it has ample time to pursue a claim, can discover too late that its right to legal action in the Czech Republic has vanished due to statute of limitations (promlčení).

The general limitation period for commercial rights in the Czech Republic is three years. This subjective period begins to run from the moment the right could have been first exercised. There is also an objective limitation period of ten years from the occurrence of the event, but the three-year period usually expires first. For specific claims, such as those arising from transport of goods, the limitation period is only one year.

Consider a practical scenario: a Luxembourg manufacturing company receives a defective shipment from a Czech supplier. The invoice was due in 2021. If the company waits until late 2024 to file a lawsuit, the Czech debtor will likely raise the objection of limitation (námitka promlčení), and the court must dismiss the claim, regardless of how valid the debt is.

Limitation periods in Czech law are interpreted strictly. Judges do not extend these periods based on "fairness" or "negotiations" unless a specific written acknowledgement of debt or a tolling agreement was signed. The defense of limitation is absolute if raised by the debtor.

The requirement to act within the limitation period is further complicated by the requirement for a pre-litigation notice. Under Section 142a of the Czech Code of Civil Procedure, a creditor must send a specific pre-action letter (předžalobní výzva) to the debtor's last known address at least seven days before filing a claim in court.

Choosing the wrong dispute resolution forum: jurisdiction and enforcement realities

The final pages of a contract, often filled with "boilerplate" clauses governing choice of law and dispute resolution, are frequently overlooked. This is a critical error. For a Luxembourg company, a poorly drafted dispute resolution clause can mean being forced into an unfavorable legal battle.

The Brussels I Recast Regulation (Regulation EU No 1215/2012) applies to civil and commercial matters between Luxembourg and the Czech Republic. The general rule is that jurisdiction lies with the courts of the Member State where the defendant is domiciled. If your Czech customer is registered in the Czech Republic, Czech courts have jurisdiction by default.

However, parties can agree on an exclusive jurisdiction clause (prorogation of jurisdiction). If you wish to have disputes resolved in Luxembourg, you must explicitly state this in the contract. If validly agreed in writing, Czech courts must respect this choice and decline jurisdiction in favor of Luxembourg courts.

Czech courts offer distinct strategic advantages. Judgments issued in Czech courts are automatically recognized and enforceable throughout the EU without a separate declaration of enforceability (exequatur). The Czech system operates under the "loser pays" principle, where the unsuccessful party usually pays the successful party's statutory legal costs.

International Arbitration is a compelling alternative. An arbitration agreement allows you to remove disputes from state courts. The Arbitration Court attached to the Economic Chamber of the Czech Republic and Agricultural Chamber of the Czech Republic in Prague is the primary permanent arbitral institution.

However, enforcement of judgments in the Czech Republic involves technical requirements. Enforcement is carried out by judicial executors ( soudní exekutoři ), who are private officers authorized by the state to seize assets, freeze bank accounts, and sell property. The efficiency of recovery depends heavily on choosing an aggressive and effective executor.

The good faith principle: beyond written words

Czech law imposes an implied duty of good faith (poctivost) in legal dealings. This extends beyond what some Luxembourg companies might anticipate. Section 6 of the Civil Code states that everyone has a duty to act honestly in legal interaction.

This means a Czech court may interpret contract terms not just literally, but in the context of fair dealing. For example, if a party exercises a contractual right to terminate specifically to cause damage to the other party (abuse of right), the court might invalidate that act even if it technically complies with the termination clause.

While the written contract is primary, this principle affects interpretation. If a contract contains ambiguous language, and the drafter attempts to interpret it in a way that is grossly unfair to the weaker party, the court will likely apply the interpretation that is more favorable to the party that did not draft the text (contra proferentem rule).

Luxembourg companies must understand that "sharp practice"—technically legal but ethically questionable maneuvering—carries a higher legal risk in the Czech Republic than in jurisdictions with stricter textualist approaches. ARROWS Law Firm can help you draft language that is clear and minimizes the risk of adverse interpretation based on good faith principles.

Data protection and cross-border processing: the GDPR imperative

Since both Luxembourg and the Czech Republic are EU Member States, the General Data Protection Regulation (GDPR) applies directly in both jurisdictions. This facilitates business, as personal data can generally flow freely between Luxembourg and the Czech Republic without the need for Standard Contractual Clauses (SCCs) or Transfer Impact Assessments that are required for non-EU transfers.

However, a critical compliance step is often missed: the Data Processing Agreement (DPA) under Article 28 of the GDPR. If your Luxembourg company (as Controller) hires a Czech partner (as Processor)—for example, a payroll provider, IT support, or cloud service—you must have a written Data Processing Agreement in place.

This contract is mandatory. It must specify the subject matter, duration, nature and purpose of processing, the type of personal data, and categories of data subjects.

Failure to execute a valid Article 28 DPA is a violation of the GDPR, exposing your company to fines of up to €10 million or 2% of total worldwide annual turnover. Furthermore, the Czech Data Protection Act (No. 110/2019 Coll.) provides specific local nuances regarding data processing (e.g., processing of birth numbers).

International reach and cross-border enforcement: leveraging EU standards

For Luxembourg companies with Czech operations, understanding how European legal frameworks facilitate cross-border enforcement is essential. As a leading Czech law firm based in Prague, ARROWS Law Firm combines in-depth knowledge of the Czech legal environment with experience in international cases.

The Brussels I Recast Regulation allows judgments obtained in Luxembourg courts to be recognized in the Czech Republic without special proceedings. However, the actual enforcement (exekuce) is governed purely by Czech national law. You cannot send a Luxembourg bailiff to Prague. You must engage a Czech judicial executor.
