Assertion of Contractual Penalties in Insolvency Proceedings

Key takeaways

Contractual penalties are not an accessory to a claim. You must file them as a separate principal amount with their own grounds for arising, not as part of default interest or costs of proceedings.
A claim for a contractual penalty that arose before insolvency can be filed. If your claim for a contractual penalty arose before the decision on the debtor's insolvency was issued, you may file it in the insolvency proceedings, subject to specific rules for the debt relief of natural persons.
Contractual penalties arising after insolvency are not satisfied. Claims for contractual penalties that arise only after the decision on the debtor's insolvency are entirely excluded from satisfaction in insolvency proceedings pursuant to Section 170(e) of the Insolvency Act.
The moment of the breach of duty is decisive. A claim for a contractual penalty arises on the day the contractual duty is breached, not on its due date, which is key for determining whether it falls before or after the insolvency.
For daily penalties, the claim arises separately for each day. If you have an agreed contractual penalty in the form of a daily penalty (e.g., 0.05% per day), only those portions that arose for the days of default preceding the decision on insolvency may be filed in the insolvency proceedings.

What happens to contractual penalties when a debtor enters insolvency?

Contractual penalties are not an accessory to a claim, but a separate claim that must be filed as a principal amount. This distinction has a major practical impact. While default interest or costs of proceedings can often be included as accessories, a contractual penalty must be listed separately in the claim application with its own reason for arising.

The Czech Insolvency Act distinguishes between two key moments that determine the fate of a contractual penalty:

The right to the contractual penalty arises before the decision on bankruptcy: If the right to the contractual penalty arose before the insolvency court issued a decision on the debtor's bankruptcy, it can generally be filed in the insolvency proceedings. However, you must respect specific rules, especially regarding debt relief for natural persons.

The right to the contractual penalty arises after the decision on bankruptcy: Contractual penalties for which the right arose only after the decision on bankruptcy are not satisfied at all in insolvency proceedings. These are claims excluded under Section 170(e) of the Insolvency Act. This principle applies regardless of whether the bankruptcy is resolved through bankruptcy proceedings, reorganization, or debt relief.

FAQ – Legal tips on the moment a contractual penalty arises

1. How do I know when my right to a contractual penalty arose?

The right to a contractual penalty arises at the moment of the breach of a contractual obligation, not at the moment it becomes due. The decisive factor is therefore the day the debtor breached the obligation for which the contractual penalty was agreed (for example, the day of default on a payment). If you are dealing with more complex cases where it is not entirely clear when the breach occurred, contact our experts.

2. What if my contract has a contractual penalty in the form of a daily penalty?

For recurring contractual penalties (e.g., 0.05% per day), the right to each daily contractual penalty arises separately. Therefore, if some days of default occurred before the decision on bankruptcy and some after, only the portion that arose before the decision on bankruptcy can be filed in the insolvency proceedings.

3. What proof do I need that the right arose before the bankruptcy?

You must be able to document the date of the breach of the contractual obligation and the existence of a valid contractual penalty agreement. This typically includes the contract with the contractual penalty clause, proof of non-performance of the obligation (e.g., unpaid invoices, records of non-delivery of goods), and any communication with the debtor. The lawyers at ARROWS will help you secure the complete documentation.

Subordinated Claims: When a contractual penalty falls to the back of the line of creditors

One of the most significant risks when enforcing contractual penalties in insolvency is their classification as so-called subordinated claims under Section 172 of the Insolvency Act. This rule applies mainly in the debt relief of natural persons and has major implications for the likelihood of your claim being satisfied.

In debt relief, a contractual penalty agreed for default on a claim becomes a subordinated claim to the extent that, together with interest, default interest, and late payment fees, it exceeds the principal amount of the filed claim at the time it arose. 

In practice, this means that if, for example, the principal is CZK 100,000 and the total claim for interest, default interest, late payment fees, and contractual penalties for default amounts to CZK 150,000, then the amount exceeding CZK 100,000 (i.e., CZK 50,000) becomes a subordinated claim.

Subordinated claims are satisfied only after all other claims subject to the insolvency proceedings have been fully paid. In practice, this means that the chance of a subordinated claim being satisfied is minimal, as the debtor's assets in debt relief are usually not even sufficient to fully satisfy ordinary unsecured creditors. Moreover, creditors of subordinated claims do not have voting rights at the creditors' meeting.

How to avoid or minimize this risk?

When negotiating contracts with business partners, it is advisable to structure contractual sanctions so that they do not exceed the limit leading to subordination in the event of insolvency. You can achieve this, for example, by:

  • A contractual penalty for a breach of obligation other than default: Contractual penalties agreed for a breach of obligation other than default on payment do not become subordinated, even if they exceed the principal.

  • Securing the claim, including the contractual penalty: Secured creditors have a preferential right to satisfaction from the security in insolvency, and this subordination rule does not apply to them in its full extent.

  • A contractual penalty as a debt from business activities: If the contractual penalty is considered a debt from business activities, the subordination rule does not apply to it.

The lawyers at ARROWS have extensive experience in drafting and reviewing contractual terms to maximize the chance of satisfying your claims, including penalties, in the event of a business partner's insolvency. We will ensure that your contracts build a solid legal foundation for future enforcement.

How to correctly file a contractual penalty in insolvency proceedings

Filing a claim in insolvency proceedings is a procedural act with strict rules and deadlines. Any mistake can lead to your application being disregarded or your claim being denied by the insolvency administrator or the debtor.

When and where to file the claim

You can file a claim application from the commencement of the insolvency proceedings, but no later than the expiry of the deadline set in the decision on bankruptcy. This deadline is typically 2 months from the publication of the decision on bankruptcy in the Insolvency Register. This is a preclusive period – late applications are disregarded, and claims filed in this way are not satisfied in the insolvency proceedings.

You file the claim application with the insolvency court that is conducting the debtor's insolvency proceedings. Information about commenced insolvency proceedings can be found in the Insolvency Register at https://isir.justice.cz.

Mandatory elements of the application

A claim application can only be filed on the prescribed form, the requirements of which are set by an implementing legal regulation. The form can be found at https://insolvence.justice.cz. The application must contain:

  • the name of the insolvency court and the case file number of the insolvency proceedings

  • identification of the debtor (name/company name, registered office/residence, ID number)

  • identification of the creditor, including any legal representative

  • the amount of the claim – it is crucial that you state the principal (the underlying debt) and the contractual penalty separately as two different principal amounts, not as a principal and an accessory

  • the reason for the claim's origin – for the principal, this will typically be a contract (purchase, work, loan, etc.); for the contractual penalty, it will be the specific breach of the contractual obligation for which the penalty was agreed

  • a description of the facts that are the reason for the claim's origin

  • the nature of the claim (whether it is enforceable, due, secured, subordinated)

  • the signature of the creditor or their legal representative

If you are an entrepreneur with a data box, filing the application electronically via the data box is mandatory.

Mandatory attachments to the application

You must attach to the claim application the documents to which the application refers. Without these attachments, the application may be rejected or the claim denied. For a contractual penalty, this includes:

  • The contract in which the contractual penalty is agreed – it must clearly state the obligation whose breach leads to the contractual penalty, and the amount or method of determining the amount of the contractual penalty

  • Proof of the breach of obligation – for example, unpaid invoices with proof of their delivery and the expiry of the due date, records of non-delivery of goods, protocols of defective performance

  • Calculation of the contractual penalty – if the contractual penalty is variable (e.g., daily), you should attach a detailed calculation stating the period and the rate used

  • Communication with the debtor regarding the contractual penalty, if any (reminders, payment demands)

If the claim is enforceable (for example, you have already obtained a final court judgment), you must prove its enforceability with a public document, i.e., typically a final and enforceable court decision or a notarial deed with consent to direct enforceability. Enforceable claims have a more advantageous position in insolvency proceedings because the grounds for their denial are limited.

The lawyers at ARROWS will ensure the complete preparation of the claim application, including all attachments, correct calculation, and adherence to deadlines. Thanks to our experience from regularly representing more than 150 joint-stock companies, 250 limited liability companies, and other clients, we know how important speed and precision are.

FAQ – Legal tips for filing claims

1. What if I don't have the complete documentation for the contract?

Even without some documents, a claim can be filed, but you must be able to prove the existence of the claim and the contractual penalty with other evidence—for example, bank statements of payments, email communication, or witness testimonies. However, the risk of the claim being denied is significantly higher in such a case. The lawyers at ARROWS will help you map the available evidence and build the strongest possible case.

2. Can I also file a claim that I am already enforcing through execution?

Yes, enforceable claims and claims being enforced through execution are also filed. This is because after the commencement of insolvency proceedings, the enforcement of judgments and executions against the debtor are subject to restrictions, and the bailiff or court executor must suspend or terminate their proceedings.

3. What if the amount of the contractual penalty changes after the claim is filed?

The claim application should be filed for the amount due to the creditor as of the date of filing. If the amount of the claim changes (for example, a daily contractual penalty accrues), you can supplement or amend the application as long as the insolvency administrator allows it. In practice, however, it is better to calculate all foreseeable claims at the time of filing to avoid unnecessary complications.

Review of Claims: Where a denial can occur and how to defend against it

After the claim is filed, a review phase follows, conducted by the insolvency administrator together with the debtor. It is in this phase that it is decided whether your claim, including the contractual penalty, will be recognized (established) or denied. A denied claim is not automatically lost, but you must be prepared to defend it in an incidental dispute, which is a demanding and costly process in terms of both time and money.

How the review of claims proceeds

The insolvency administrator reviews the claim applications mainly based on the attached documents and the debtor's accounting or records. The administrator invites the debtor to comment on the filed claims. Subsequently, they compile a list of filed claims, in which they explicitly state for each claim whether they recognize or deny it, and if they deny it, to what extent (authenticity, amount, or ranking).

In the debt relief of natural persons, the review takes the form of a personal meeting between the insolvency administrator and the debtor, at which the debtor has the last opportunity to deny claims. The administrator then prepares a review report, which contains a list of filed claims with the positions of both the administrator and the debtor indicated.

Reasons why a contractual penalty may be denied

The insolvency administrator, the debtor, or another creditor may deny a claim as to its authenticity, amount, or ranking. For a contractual penalty, the most common reasons for denial are:

Denial of authenticity means disputing that the claim ever arose or that it has already been extinguished. For a contractual penalty, this could involve assertions that:

  • the contractual penalty was not validly agreed in the contract (vagueness, contrary to good morals)

  • the debtor did not breach the obligation to which the contractual penalty was related

  • the contractual penalty has already been paid or otherwise extinguished (e.g., by waiver)

  • the right to the contractual penalty is statute-barred

Denial of the amount means that the amount of the filed claim is disputed. For a contractual penalty, this typically involves:

  • disagreement with the calculation (different number of days of default, different rate)

  • objections that the contractual penalty is unreasonably high and should be moderated (reduced) by the court

Enforceable claims have an advantage in this regard – if they are awarded by a final decision of a court or other competent authority, they can only be denied on very limited grounds under Section 199(2) of the Insolvency Act. The denying party is not permitted a different legal assessment of the matter, but only new facts that were not and could not have been raised in the original proceedings (for example, a forged signature).

How to defend against the denial of a claim

If your claim, including the contractual penalty, is denied, you have two options:

A) Incidental dispute to determine the authenticity, amount, or ranking of the claim

If a non-enforceable claim has been denied, you as the creditor must file an action with the insolvency court to determine that the denied claim is legitimate. The deadline for filing the action is 30 days from the review hearing. If you do not file the action in time, your claim will no longer be considered in the insolvency proceedings.

In an incidental dispute, you bear the burden of proof that your claim is authentic and in the correct amount. This means you must prove to the court all the facts establishing the existence of the claim – the conclusion of the contract, the agreement of the contractual penalty, the debtor's breach of obligation, and the occurrence of damage (if the contractual penalty serves a compensatory function).

If an enforceable claim has been denied, the action is filed by the insolvency administrator (not the creditor) to determine that the claim is not legitimate. In this case, it is the administrator who must prove the grounds for denial.

B) Withdrawal of the denial

In some cases, the insolvency administrator may withdraw their denial, for example, if the creditor subsequently provides the necessary evidence. The withdrawal of the denial results in the claim being established without the need for an incidental dispute.

Incidental disputes are procedurally and substantively demanding, and their outcome can fundamentally affect whether you receive even a portion of your claims. The lawyers at ARROWS have extensive experience in representing clients in incidental disputes and will provide you with expert legal argumentation and evidence management.

Moderation of a Contractual Penalty: How a court can reduce your claim

Another risk that can significantly reduce the amount of satisfaction of a contractual penalty is its moderation (reduction) by the court. Under Section 2051 of the Civil Code, a court may, at the debtor's request, reduce an unreasonably high contractual penalty.

How to avoid the risk of moderation

When agreeing on contractual penalties in contracts with business partners, it is advisable to:

  • Choose a reasonable amount for the contractual penalty – reasonableness depends on the circumstances of the case, but a limit of approx. 0.5% per day is generally considered reasonable; higher rates may be considered risky in terms of 

  • Clearly define the function of the contractual penalty – if it is intended to serve as a lump-sum compensation for damages, this can be explicitly stated in the contract

  • Include a mechanism in the contract for reducing the penalty under certain circumstances, so that the court does not have to resort to moderation at all

  • Enforce contractual penalties actively and without undue delay – long-term passivity on the part of the creditor may be taken into account by the court as a mitigating circumstance for the debtor during moderation

The lawyers at ARROWS will help you set up contractual penalties so that they are legally robust, yet reasonable and enforceable. Thanks to our experience, we know which formulations and rates will stand up to judicial review.

Penalty for Overstating a Claim: When you face a fine instead of satisfaction

One of the lesser-known but important provisions of the Insolvency Act is Section 179(1), which allows the insolvency court to penalize the overstatement of the actual amount of a filed claim.

If the actual amount of the established claim (including the contractual penalty) is less than 50% of the filed amount, the court may, at the request of the insolvency administrator, order the creditor to pay a certain amount into the insolvency estate. The court will determine this amount with regard to all the circumstances of the filing and review of the claim, but not exceeding the amount by which the filed claim exceeded the extent to which it was established.

In other words, if you filed a claim for CZK 1,000,000, but after review or an incidental dispute, it was established at only CZK 300,000 (i.e., 30% of the filed amount), the court may order you to pay up to CZK 700,000 into the insolvency estate.

How to avoid the penalty for overstatement

  • Carefully calculate the claim, including the contractual penalty, and ensure the calculations are correct

  • Attach all necessary evidence to the application to make it clear that the amount of the claim is justified

  • If in doubt about the amount, consult a lawyer – if there is legal or factual uncertainty about part of the claim, it is better not to file it at all than to risk a penalty

  • Do not file claims that are deliberately inflated with the intention of obtaining higher voting rights or greater satisfaction at the expense of other creditors

The lawyers at ARROWS will ensure the precise calculation of your claims, including contractual penalties, and minimize the risk of a penalty for overstatement. We pride ourselves on precision and a detailed knowledge of insolvency law.

FAQ – Most common legal questions about enforcing contractual penalties in insolvency

1. Is it possible to file a contractual penalty even if it is not yet due?

Yes, claims that are not yet due or are conditional can also be filed in insolvency proceedings. The decisive factor is that the right to the contractual penalty has already arisen (a breach of a contractual obligation has occurred), not that it is already due. However, if the contractual penalty arose after the decision on bankruptcy, it cannot be satisfied in the insolvency proceedings at all.

2. Can I file a contractual penalty separately if I have already filed the principal?

If you did not include the contractual penalty in the original application and the deadline for filing claims has not yet expired, you can file a supplementary application or amend the original one. However, if the deadline has already passed, the additional application will be disregarded. It is therefore crucial to file all claims, including contractual penalties, comprehensively and on time.

3. Who pays the costs of an incidental dispute if the claim is established?

In an incidental dispute, the general rules on the reimbursement of costs of proceedings under the Code of Civil Procedure apply. If the creditor succeeds in the incidental dispute, they generally have the right to reimbursement of the costs of the proceedings from the denying party. The costs may include the court fee, the lawyer's fee, and cash expenses. Conversely, if the creditor is unsuccessful, they may be ordered to reimburse the costs of the proceedings to the other party.

4. What if the debtor objects that the contractual penalty is too high?

Moderation (reduction) of a contractual penalty is possible only at the debtor's request and only if the court concludes that it is unreasonably high. Unreasonableness is assessed with regard to the specific circumstances of the breach of obligation, not just the amount of the contractual penalty. The court takes into account the function of the contractual penalty, the value and importance of the breached obligation, the amount of damage caused, and other circumstances. .

5. Can the insolvency administrator offer an out-of-court settlement regarding the contractual penalty?

Yes, the insolvency administrator can negotiate with the creditor about the recognition or amount of the claim, and in some cases, it may be advantageous to reach an agreement instead of a dispute. However, any agreement should be in writing and contain clear terms to avoid later disputes. The lawyers at ARROWS will help you negotiate the best possible terms in an out-of-court settlement.

6. What are the chances of actually recovering a contractual penalty in insolvency?

This depends on many factors: whether it is a bankruptcy, reorganization, or debt relief; whether you are a secured or unsecured creditor; the size of the insolvency estate; and how many other creditors have claims. Generally, the recovery rate for claims in bankruptcy in the Czech Republic is around 5–12%, and for secured creditors, 30–40%. This is precisely why it is crucial to structure contracts preventively and to act quickly and correctly in the event of insolvency.
