Limitations and exclusions of liability in business to business contracts in Czech Republic

The general legal framework governing contractual limitations and exclusions of liability in B2B contracts is governed by the Czech Civil Code (Act No. 89/2012 Coll.). The Czech Civil Code applies unless the business parties agree otherwise. This is, however, not possible where a statutory provision does not allow for such deviation. 

Under Czech law, court judgments are not formally binding as a source of law. However, decisions of the Czech Supreme Court and the Constitutional Court carry significant persuasive authority and lower courts routinely follow them. 

Although a party may discontinue negotiation of a contract, liability may arise even at the pre-contractual stage. Under the “culpa in contrahendo” principle, where business parties have reached a stage at which the conclusion of the contract appears highly probable, and one party nevertheless terminates negotiations without justified reason, that party is liable to compensate the other for the resulting loss. The relevant concepts are defined as follows:

• highly probable means that all essential terms have already been agreed and only formal completion remains, or that the contract is pending solely on a specific event; and
• justified reason means that continuing the negotiations has become more burdensome for a party, including due to a change in market conditions.

Liability may be limited (modified) or even excluded by the specific contract type (exemptions apply). The law contains tailored rules for specific types of contracts: for instance, in a sales contract, the buyer’s remedies for defects may be subject to notification duties and time limits; contracts for work may be governed by specific acceptance and warranty rules; and B2B leases are subject to their own provisions that limit the parties’ ability to deviate from statutory allocations of risk.

Contractual liability is objective, meaning the contracting party is liable for breach of its contractual obligation irrespective of fault. If liability has not been excluded or modified, a party may only be released from liability if it proves that performance was prevented by an extraordinary, unforeseeable, unavoidable and insurmountable obstacle arising independently of its will (force majeure). A party cannot rely on this defence if the problem arose from its own circumstances, occurred only after it was already in default, or it was a risk it had agreed to bear.

The general regime of delict (tort) liability provides overarching rules that also govern limits of contractual liability. These include the principle of objective liability for breach of contract, rules on solidary and divided liability of multiple tortfeasors, contributory negligence, and the mandatory restrictions on contractual exclusions or limitations of duty to compensate for harm. 

Yes. The Czech Civil Code contains mandatory provisions that render certain exclusions or limitations of liability void and unenforceable in commercial contracts between businesses, regardless of the parties’ contractual arrangement. It is prohibited to exclude or limit in advance compensation for harm to a person’s natural rights (typically life and health), compensation for harm caused intentionally or through gross negligence, and the weaker party’s right to compensation for any harm. Moreover, these rights cannot be validly waived in advance.

The law embeds a general principle of protecting the weaker party, prohibiting abuse of significant economic position to create or exploit dependency or an unjustified imbalance of rights and duties. The protection of the weaker party is not limited to consumers. 

Certain “statutory guarantees” are also considered mandatory under the Czech legal framework: a declaration of intent by which the transferor limits in advance the statutory scope of its obligations arising from defective performance is ineffective, so such a limitation of liability for defects is not enforceable. 

In standard-form contracts, limitation clauses that are particularly disadvantageous and lack a reasonable basis are invalid. In B2B relationships, this correction applies if the clause grossly violates commercial customs and the principle of fair business dealings. Furthermore, the Czech Civil Code provides that a clause in standard terms that the other party could not reasonably expect is ineffective unless expressly accepted (the “surprising clause” rule). 

In sectors subject to special regulations, additional mandatory limitations apply. In transportation, transport regulations may not limit compensation for bodily injury, and any limitations do not apply in cases of intent or gross negligence on the part of the carrier. Under the product liability regime, a prior waiver of the right to compensation is ineffective, and contractual exclusions of liability are not recognised.

Unilateral declarations by which a business party “excludes” or limits its obligation to compensate for harm vis-à-vis an indefinite group of persons are also legally ineffective. They are meaningful only as a warning of risk if made before the harm occurred. 

A general rule applies: any provision that is contrary to public policy or clearly disrupts public order is invalid, so the court will not recognise any limitation or exculpatory clauses that exceed these boundaries.

Under Czech law, the terms “consequential loss”, “indirect loss”, and “special loss” have no legal meaning. Contractual liability is based primarily on the existence of a causal link between the breach of contract and the loss suffered, with recoverable damages generally comprising actual loss and lost profit. While Czech law does not expressly formulate foreseeability as a statutory limitation on the scope of damages, Czech legal doctrine and case law use foreseeability as a corrective factor when assessing whether certain extraordinary or atypical losses are recoverable. The general rule on causation requires that the damage be in an adequate causal connection with the breach.

Business parties are, in principle, free to contractually exclude or limit liability for particular categories of loss, but because these English-law-derived terms lack a settled definition in Czech legal doctrine or case law, any exclusion clause using them without a precise contractual definition risks significant interpretive uncertainty. It is therefore essential that B2B contracts governed by Czech law define such terms autonomously within the contract itself, rather than relying on their common-law meaning.

In the event of a dispute, Czech courts would interpret an undefined term such as “consequential loss” in accordance with the general principles of interpretation set out in the Czech Civil Code, namely interpretation according to the true will of the parties, the meaning a reasonable person in the addressee’s position would attach to the expression, and, critically, where a term permits various interpretations, it will (in cases of doubt) be construed to the detriment of the party that first proposed it. Prior dealings, the circumstances of the conclusion of the contract, and subsequent conduct of the parties are all relevant interpretive aids.

In addition to the above, a legal act contrary to good morals is invalid. Where the conflict is obvious, the court must consider such invalidity ex officio. Where the conflict with good morals is not obvious, relative invalidity applies (invocable only by the affected party). Separately, a mistake about a decisive circumstance induced by the other party renders the legal act relatively invalid; if a limitation or exclusion clause was agreed under such an induced mistake, the clause is unenforceable under Czech law.

Yes, it is generally permissible under Czech law to contractually exclude or limit liability for loss of profit, revenue, data, goodwill or anticipated savings in B2B relationships, subject to the mandatory limitations discussed above (in particular, exclusions may not cover liability for intentional harm or gross negligence, harm to a person's natural rights, or prejudice the weaker party's right to compensation). There are no special statutory carve-outs targeting these specific heads of loss. In practice, parties rely on the general regime for contractual limitations and exclusions of liability, with market practice often carving out loss of profit and excluding "indirect" or "consequential" loss through appropriate drafting.

For data loss in SaaS-type arrangements, deletion or unavailability of data in contracts for SaaS solutions, the provider bears objective liability for damage irrespective of fault, unless it proves that performance was prevented by an extraordinary, insurmountable obstacle independent of its will. Data are not classified as a “thing” in the traditional property law sense and are not normally capable of ownership in the same way as tangible property. Czech law generally protects data through contractual rights and specific statutory regimes, rather than through ownership of the data itself. Legal protection and the character of recoverable harm typically turn on database rights, trade secrets, or personal data rules, rather than proprietary title. 

Goodwill is a legally protected interest under Czech law. Legal entities enjoy protection of their reputation, and harm to goodwill caused by unfair competition is actionable. However, goodwill remains difficult to quantify. Czech courts require concrete evidence of the monetary value of reputational harm, and the claimant must demonstrate an adequate causal link between the breach and the loss of goodwill. 

Finally, anticipated savings are not generally a recognised autonomous category of loss, and would typically fall within the broader concept of lost profit.

Yes, financial caps on liability are commonly upheld under Czech law. There are no special statutory ceilings on cap levels, so enforceability turns on the general rules for exclusion and limitation of liability as described above. Caps can target losses arising from defined obligations or apply across the contractual relationship. Amounts may be fixed or set as a proportion of a clear metric, such as the contract price. Parties often pair caps with type-based carve-outs, such as excluding lost profit or clearly defined “indirect/consequential” loss.

Two further mechanisms deserve attention in a B2B context: 

First, where a cap is embedded in a contract concluded by adhesion, the clause is valid only if the weaker party was made aware of it and of its significance; a referral to terms outside the main text that the counterparty never saw may be disregarded by a court. 

Second, a contractual penalty can serve as a de facto financial cap. Once a contractual penalty is agreed for breach of a specific obligation, the creditor has no right to claim damages arising from that same breach beyond the penalty amount, unless the parties expressly agree otherwise (i.e. the parties may contractually reserve the right to claim damages in addition to the contractual penalty). If the contractual penalty is disproportionately high, the court may reduce it to the level of actual loss incurred. In practice, parties tend to use contractual penalties not only as an incentive for performance but also as a tool to cap and make predictable their maximum exposure for defined breaches.

There is no special statutory regime governing “exclusive remedy” clauses in Czech law. Their enforceability is assessed under the general rules on limitations and exclusions of liability summarised above. A court will uphold such a clause provided those limits are respected (i.e. it does not exclude liability for intentional harm, gross negligence, or harm to natural rights and it is not contrary to good morals under the Czech Civil Code).

Czech law is guided by the principle of autonomy of will. For a court to treat the clause as truly exhaustive, the parties’ intent must be expressed unambiguously. Under the interpretive rules in the Czech Civil Code, any term that cannot be interpreted using its ordinary meaning will be assigned the meaning it carries specifically between the parties. If the clause does not explicitly and unmistakably state that the listed remedy is the sole and exclusive remedy, and if other statutory remedies (such as the right to withdraw from the contract or to claim a price reduction) are not expressly waived to the extent permitted, there is a material risk that the counterparty may successfully challenge its exhaustiveness or a court will decline to treat the remedy as exhaustive.

The common-law doctrines of severance and the blue-pencil test have no application under Czech law. Czech law addresses partial invalidity through its own statutory framework. 

As a matter of general principle, Czech law requires that a legal act be regarded as valid rather than invalid wherever possible. This interpretive presumption informs the entire approach to partial invalidity and favours the preservation of contractual arrangements to the greatest extent possible.

Where the ground of invalidity affects only a part of a legal act that can be separated from its remaining content, only that part is invalid, provided it can be presumed that the legal act would have been made even without the invalid part, had the parties recognised the invalidity in time. Two cumulative requirements must therefore be satisfied: first, the remaining provisions must be objectively capable of standing on their own as a valid legal act (separability); and second, the will of all parties must support the conclusion that the transaction would have proceeded without the invalid portion (hypothetical intent). Courts assess separability by reference to substance rather than by mechanically striking out words. Non-essential and incidental terms are generally regarded as separable, whereas provisions constituting essential elements of the legal act are not — although exceptions exist.

Where a clause is invalid solely because a specific parameter, such as a monetary amount, time period, geographical scope, or other quantitative or qualitative limit, exceeds what the law permits, the court is not required to strike out the entire clause. Instead, the court may adjust that parameter to a level it considers fair and proportionate. Importantly, the court exercises this power independently and is not bound by the parties' proposals. However, it must assess whether the affected party would have entered into the contract at all had it known of the invalidity. This mechanism is particularly significant for liability caps: if a contractual cap on liability is set at a level that renders it invalid (for example, because it effectively excludes liability for harm caused by gross negligence), the court can replace the invalid cap with a fair one rather than invalidating the limitation clause entirely.

In practice, contractual severability clauses are a standard feature of Czech commercial contracts. Such clauses expressly state the parties' intention that the remainder of the agreement shall remain valid if any individual provision is found invalid or unenforceable. They serve as evidence of the parties' hypothetical intent, thereby facilitating the application of the partial invalidity rules described above. While not strictly necessary, such clauses reduce evidential uncertainty and are considered best practice.

Czech law distinguishes two types of limitation periods. The first is the subjective limitation period, which starts running from the day the creditor learns (or should have learned) of the circumstances giving rise to its claim (that damage occurred and who the liable party is) — the general length is three years. 

The second is the objective limitation period, which runs independently of the parties' knowledge and sets an absolute outer time limit — generally ten years from occurrence of damage, fifteen years for intentional harm under Czech law. Parties may freely agree to shorten or extend the subjective period, but only within the range of one to fifteen years. The objective period, by contrast, cannot be modified by contract at all; if it expires first, the claim is time-barred regardless of what the parties have agreed.

The limitation period may not be shortened by agreement where: 

• the claim concerns compensation for harm to freedom, life, or health; or
• the right arises from an intentional breach of duty (which doctrine extends to breaches committed through gross negligence). 

Any such agreement is treated as either absolutely invalid (meaning courts will consider it ex officio) or a sham legal act and the courts will disregard it accordingly. Lengthening the period for these claims remains permissible.

Similarly, any agreed shortening or extension that operates to the detriment of the weaker party is disregarded. In equal-footing B2B relationships this constraint is of limited practical relevance, but it may become material where one contracting party qualifies as the weaker party under general civil law principle, for example, where the subject matter of the contract falls outside the party's actual business expertise.

Certain special statutory regimes further restrict the parties' contractual freedom. In insurance relationships, agreements altering limitation periods are generally disregarded, with a narrow exception for large-risk non-life insurance. In the area of package travel, the limitation period for defect-related price reductions and damages may not be shortened below two years, a restriction primarily relevant in B2C contexts but potentially applicable where businesses purchase travel packages.

Czech law does not recognise a free-standing "public policy" doctrine in the common law sense that would independently override B2B limitation or exclusion of liability clauses outside the statutory framework. The constraints are exhaustively codified in the mandatory Czech Civil Code rules described above, supplemented by the general clause on good morals and public order. 

The Czech Civil Code does recognise public order as a ground of absolute invalidity, which courts apply ex officio, but this operates within the same statutory framework. It overlaps substantially with the prohibition on acts contrary to good morals and the mandatory protections already discussed (e.g. advance exclusions of liability, unilateral pre-disclaimers, limitation-period restrictions).

The Civil Code also contains an anti-exploitation provision (usury) that renders invalid any contract concluded by taking advantage of the other party’s distress, inexperience, mental weakness, agitation, or recklessness where the mutual performances are grossly disproportionate. Entrepreneurs acting in their business are expressly barred from invoking this provision, but a court may still apply the general invalidity grounds (e.g. good morals, public order) to the same facts in an extreme case.

The Czech approach is entirely codified: the boundaries of party autonomy are set exclusively by mandatory statutory norms, good morals, and public order, without residual judicial discretion to override otherwise valid clauses on equitable or policy grounds.

If Czech law governs the contract, whether chosen by the parties (Article 3 of Rome I Regulation) or determined by the default rules (Articles 4–8 of Rome I Regulation), the full Czech regime on limitation and exclusion of liability applies, regardless of where the goods are delivered or the services are performed. 

There is no "international version" of Czech contract law that would modify the rules just because a foreign element is present. That said, two important nuances arise from the Rome I Regulation. First, when assessing how performance should have been carried out and what steps should be taken about defective performance, the court must also take into account the law of the country where performance actually takes place (Article 12(2) of Rome I). Second, if the law of the country of performance contains overriding mandatory rules that make performance unlawful, the court may give effect to those rules even though Czech law governs the contract (Article 9(3) of Rome I). In practice, this means that while Czech liability rules travel with the contract, the local regulatory environment at the place of performance cannot be entirely ignored. 

Separately, in some regulated sectors, such as international carriage, directly applicable international conventions may contain their own mandatory liability limits or exclusions. This should be assessed on a case-by-case basis by reference to the relevant mode of transport and the states involved, rather than by assuming that every commonly cited carriage convention applies.

Where a foreign law governs the contract, its own rules on limitation and exclusion of liability will apply accordingly, even if performance takes place in the Czech Republic. The Czech law restrictions are not considered to constitute overriding mandatory provisions (imperative norms) within the meaning of applicable conflict-of-law rules and would not, therefore, be imposed on a contractual relationship governed by foreign law merely because the Czech Republic is the forum state. However, the application of foreign law may be refused if its effects would be manifestly incompatible with the public policy (ordre public) of the Czech Republic.
