Set-off of Claims in Insolvency

When is a set-off permitted and how can it be used as a security instrument?

Set-off of claims in insolvency is an effective tool that can dramatically change your position as a creditor if used correctly. Find out under what conditions you can set off mutual claims during insolvency proceedings and how to use this legal instrument as an effective security tool. In this article, you will find specific answers to questions regarding time limits, legal requirements, and the risks you may face if you proceed incorrectly.

Set-off of Claims in Insolvency

Key takeaways

Set-off is strictly limited in insolvency proceedings. Once insolvency proceedings are initiated, a prohibition on the individual satisfaction of creditors applies, and set-off is considered a form of such satisfaction, which is why its use is restricted.
The decisive factor for a set-off is when the claim arose. A set-off is permissible if the statutory conditions for it were met before the court's decision on the method of resolving the insolvency, as stipulated in Section 140 of the Insolvency Act.
Claims arising after the declaration of insolvency cannot be set off. If your claim arose only after the court's decision on the debtor's insolvency, it generally cannot be set off in the insolvency proceedings.
Lack of knowledge of the insolvency may permit a set-off. If, at the time your claim arose, you did not know and could not have known about the debtor's insolvency, a set-off may be permissible; however, this fact must be proven.

What is a set-off and why is it controversial in insolvency

Once insolvency proceedings are initiated, a so-called prohibition on the individual satisfaction of creditors comes into effect. This means that no creditor can, on their own initiative, enforce a claim against the debtor outside the framework of the insolvency proceedings. However, a set-off is a form of individual satisfaction, and therefore its use in insolvency is strictly limited.

When a set-off can be used: The time aspect is decisive

The key factor for assessing the admissibility of a set-off is the moment when the eligibility for the set-off arose. According to Section 140 of the Czech Insolvency Act, the set-off of mutual claims between the debtor and a creditor is permissible after a decision on bankruptcy has been made, provided that the legal conditions for this set-off were met before the decision on the method of resolving the bankruptcy.

In practice, this means that if you had a claim eligible for set-off against the debtor before the court decided on the bankruptcy and the method of its resolution, you can also exercise the set-off during the insolvency proceedings. In contrast, claims that arose only after the decision on bankruptcy cannot usually be set off.

FAQ – Legal tips on the time aspects of a set-off

1. How do I know if I have a set-off eligible claim?

A set-off eligible claim must be due, monetary, and mutual. This means you must be able to demand performance from the debtor, and at the same time, you are obliged to perform for them. For an immediate review of your situation, write to us at consultation@arws.cz.

2. What if I did not know about the debtor's bankruptcy?

If you did not know and could not have known about the debtor's bankruptcy when your claim arose, the set-off may be permissible. However, this must be proven. Need a legal analysis? Contact us at consultation@arws.cz.

Basic conditions for a set-off in insolvency proceedings

For a set-off to be permissible in insolvency, the following conditions must be met simultaneously:

  1. Mutuality of claims – there must be a mutual obligation where both parties can demand performance from each other.

  2. Same kind – the claims must be of the same kind, typically monetary.

  3. Maturity – both claims must be due, or at least one of them.

  4. Eligibility for set-off – the claims must not be excluded from set-off by law or contract.

  5. Creditor registration – the creditor must become a registered creditor in the insolvency proceedings.

The last condition is often overlooked but is crucial. If a creditor does not register for the insolvency proceedings, they cannot exercise a set-off. The Czech Insolvency Act requires the creditor to register their claim, and only then can they exercise the right to a set-off.

Risks and penalties for an unauthorised set-off

An unauthorised set-off can lead to serious legal consequences. If you set off a claim in violation of the Czech Insolvency Act, the insolvency administrator can file an avoidance action and demand the exclusion of such performance from the insolvency estate.

Set-off as a security instrument: A practical guide

A set-off can be a very effective security instrument if used correctly and in a timely manner. A creditor who has a set-off eligible claim against the bankrupt debtor is essentially in the position of a secured creditor, as their claim will be satisfied in full by the set-off. A set-off in insolvency is not automatic. It must be explicitly exercised and all conditions must be proven to have been met.

The practical procedure is as follows:

  1. Identify mutual claims – conduct an audit of all obligations between you and the debtor.

  2. Verify eligibility for set-off – check whether the claims meet the statutory conditions.

  3. Register for the proceedings – become a registered creditor by filing a claim registration.

  4. Exercise the set-off – you can exercise the set-off in writing to the insolvency administrator.

The lawyers at ARROWS deal with this agenda on a daily basis and know what evidence is key for the court. We will be happy to help you – just write to consultation@arws.cz

FAQ – Legal tips on using set-off as security

1. Can a set-off replace traditional security like a pledge?

A set-off has a similar effect to security, but it cannot be considered a complete substitute. Each instrument has its specific use. For specific recommendations for your situation, write to us at consultation@arws.cz.

2. How quickly do I have to exercise a set-off?

You should exercise the set-off as soon as possible after the insolvency proceedings have been initiated, ideally at the same time as registering the claim. Missed deadlines can be fatal. Want to be sure? Get in touch with us at consultation@arws.cz.

Why a set-off in insolvency is more complex than it seems

At first glance, a set-off may seem like a simple legal act. However, the practice is much more complicated. In the real world, we encounter dozens of hidden exceptions, procedural details, and connections to other regulations that a layperson often does not see.

For example:

  • Awareness of bankruptcy – if you knew or, given the circumstances, must have known about the debtor's bankruptcy, the set-off may be ineffective.

  • Incongruous performance – if your claim arose shortly before insolvency from an unusual legal act, it may be challenged by an avoidance action.

  • Claims against the insolvency estate – these claims are set off under a completely different regime.

The ARROWS law firm deals with this agenda daily and knows where the dangerous pitfalls lie. Our experience from more than 150 joint-stock companies, 250 limited liability companies, and 50 municipalities and regions allows us to identify risks that others overlook. It is safer for the client to have the entire matter professionally handled – just contact our office at consultation@arws.cz

Bankruptcy vs. reorganisation: Different rules for set-off

Insolvency proceedings can take various forms, with bankruptcy or reorganisation being the most common. Each form has different impacts on the possibility and conditions of a set-off.

Bankruptcy is the most common path. The insolvency administrator gradually liquidates the debtor's assets and distributes the proceeds to the creditors according to the law. In bankruptcy, a set-off is applied according to Section 140 of the Czech Insolvency Act, meaning if the conditions were met before the decision on bankruptcy, the set-off is permissible.

A creditor with initiative and knowledge of the procedure can thus achieve a situation where they are satisfied in full, while other unsecured creditors receive only a few percent. This is precisely why the insolvency administrator tends to challenge set-offs. There is a risk that the set-off will remove an asset from the insolvency estate that could have satisfied other creditors.

Reorganisation is a recovery method where the debtor (or creditors) prepares a plan to keep the business alive and get it back on its feet. Here, a set-off is more complicated. The publication of a proposal to permit reorganisation in the insolvency register automatically prohibits the set-off of claims – this is a strong tool to protect the liquidity of the reorganised company. 

Therefore, a creditor cannot individually set off claims during the preparation of the reorganisation plan to get rid of their obligation to the debtor; it would be a total sabotage of the plan. However, this prohibition can be broken by a court's preliminary injunction – if it were a set-off that threatens the company's liquidity in a particularly serious way.

What are the practical differences? In bankruptcy, a creditor with mutual claims has a realistic chance to benefit from the insolvency dispute with their initiative and knowledge of the law. In reorganisation, it is the opposite; the creditor is motivated to cooperate with the debtor and their creditors for the plan to succeed. The lawyers at ARROWS will understand your specific situation and advise on the optimal strategy for you.

Preventive strategies: How to protect yourself against avoidance actions

The best defence is good prevention. If you are a creditor and you realise that your business partner is in trouble, it is time to clarify your legal position. An avoidance action by the administrator can come up to three years after you have made the set-off, which is a long time when you might think everything is fine, and then the court decides to overturn your transaction.

The basis is documentation proving your good faith. If you are performing a set-off, keep evidence that you did not know and could not have known about the debtor's bankruptcy. Usual communication, standard business procedures, absence of warnings. All this will help later if the insolvency administrator claims you should have known. ARROWS will help you structure your documentation and communication so that your good faith is proven to be watertight.

Ensure the demonstrable legality of the transaction. If you want your claim to be eligible for a set-off, do not do anything suspicious. Do not buy assets below market price, do not inflate invoices, do not create artificial situations. The set-off must be a consequence of a normal business relationship. If you are not sure, consult a lawyer before you perform the set-off.

Monitor the possible initiation of insolvency proceedings. As soon as you notice that the debtor is in trouble and an insolvency process is possible, immediately find out if it has already been initiated, and if so, register without delay. Missing the deadline for registration means you cannot exercise the set-off at all. ARROWS has experience with managing deadlines and never misses them – just give us the instruction at consultation@arws.cz

Assess the pros and cons of this set-off and, before setting off, verify what your actual benefit from this set-off is. If you have a sufficiently low level of risk in your claim (e.g., it is covered by security) and, on the other hand, a high risk that your set-off would be challenged, you might prefer to avoid the set-off and have the matter resolved in the regular insolvency proceedings.

Risks and penalties

How ARROWS helps (consultation@arws.cz)

Set-off without verifying legal conditions – the creditor thinks that if they have claims, they can set them off

Legal analysis before the set-off – we will check all conditions and ensure a safe set-off 

Ignorance that the debtor is already in insolvency – the creditor knows the debtor has problems but doesn't know they are formally in insolvency

Register and situation check – we will find out the debtor's status

Suspicious logic of the set-off – the creditor invents a reason for having a claim in order to have something to set off; the court sees through this

Authentic business relationships – the set-off must be a natural consequence of your relationship

Forgetting about time – the creditor waits to secure themselves, but in the meantime, deadlines are running

Deadline system and timeline – you won't miss any deadline

FAQ – Most common legal questions about setting off claims in insolvency

1. Can I set off a claim that arose after the insolvency proceedings were initiated?

Generally, no. A set-off is only permissible for claims that were eligible for set-off before the decision on the method of resolving the bankruptcy. However, there are exceptional situations, e.g., for claims against the insolvency estate. To assess your specific case, write to us at consultation@arws.cz.

2. What if I initiated a set-off, but the insolvency administrator disagrees with it?

The administrator can challenge the set-off with an avoidance action. In that case, you will go to court, which will assess whether all legal conditions were met. The ARROWS law firm has extensive experience in defending set-offs before courts and represents clients in incidental disputes. Need representation? Contact us at consultation@arws.cz.

3. Do I really have to become a registered creditor if I want to set off a claim?

Yes, that is a necessary condition. If you do not register your claim, you cannot exercise any rights in the insolvency proceedings, including the right to a set-off. The registration has strict formal requirements. The lawyers at ARROWS will prepare your registration to withstand any objections. Want to be sure? Write to consultation@arws.cz.

4. Can the debtor set off my claim against their claim against me?

Yes, the debtor can also set off, but only under the same conditions as the creditor. However, if the set-off were to cause a non-negligible reduction of the insolvency estate, such a set-off may be ineffective. Need to analyse mutual rights and obligations? Contact us at consultation@arws.cz.

5. How long does it take for a court to decide on the admissibility of a set-off?

The length of the proceedings varies depending on the complexity of the case and the court's workload. On average, it ranges from 6-18 months. ARROWS can significantly speed up the proceedings thanks to thorough preparation and knowledge of procedural tricks. Want a quick solution? Get in touch with us at consultation@arws.cz.
