Set-off notice in the Czech Republic: deadlines
A German parent company discovers that its Czech subsidiary owes money under one contract and is owed money under another, with the same counterparty on both sides. Someone in the group asks whether the two claims can simply be cancelled against each other, and how fast that has to happen. The answer turns on how the set-off notice is delivered, not on how obviously the two figures match.
A set-off notice is a unilateral declaration that extinguishes two mutual claims from the moment it reaches the other side, provided both claims are due and of the same kind. Czech contract law treats delivery, not agreement, as the trigger: the effective date is the date the notice is proven to have arrived, and that single date fixes every deadline that follows.
What follows sets out when a notice actually resolves a claim, what the underlying contract must allow, the deadline that starts running once the notice is sent, what the supporting file has to contain, and the point at which waiting stops being a reasonable choice.
When does a set-off notice actually resolve a cross-border claim?
A set-off notice resolves a claim only when both claims are due, of the same kind and not excluded by the contract or by the applicable statute. For a foreign parent, the practical question is narrower than the legal one: whether the claim being set off is genuinely undisputed, or whether the counterparty has already flagged a defect, a delay, or a partial performance that turns the claim into something contested rather than simply unpaid.
Czech practice does not require the two claims to arise from the same contract. A supply debt can be set off against a services claim, a rental claim against a loan repayment, as long as both are payment obligations expressed in the same currency and both have matured. Where one side is a Czech company and the other a foreign parent or sister company, the notice still has to be addressed to the entity that is actually the creditor of record, not to the group as a whole.
The group logic that treats intercompany debt as one balance rarely survives contact with a single counterparty's contract file.
A notice sent after the counterparty has already moved to enforce its own claim does not reach back: the missed window before that stage closes the route to set-off entirely, and no later declaration reopens it.
Does the underlying contract allow set-off under Czech law?
Most Czech-law framework agreements are silent on set-off, which by default leaves the statutory right intact – but a growing number of contracts drafted for cross-border supply expressly exclude it, usually in the same clause that deals with contract termination and retention of title. Reading that clause first saves the notice itself from being void from the outset.
Retention-of-title clauses in particular interact badly with set-off: if title to goods has not passed, the payment claim tied to those goods may not be "due" in the sense the set-off rule requires, even though an invoice has been issued. The same applies where the contract makes payment conditional on a separate acceptance protocol. A notice built on a framework agreement with a Czech party has to be checked against that specific document, not against a template used elsewhere in the group.
An Austrian parent avoided repeating a payment worth several months of the subsidiary's turnover after its set-off notice was reissued with proof of delivery before the contractual deadline lapsed (winter 2025). The first notice had been sent by email with no delivery confirmation and was disputed on that basis alone.
A group treasury discovering two open claims on the same counterparty usually assumes the numbers speak for themselves; the contract, and how the notice reaches the other side, decide whether they do.

What deadline runs once a set-off notice is sent under Czech contract terms?
The deadline that matters is not a fixed number of days after signing; it is the date the notice is proven to have reached the other party. From that date, the set-off is treated as having taken effect retroactively to the moment the claims first met the conditions for set-off – due, of the same kind, not excluded. Any later dispute over the amount does not undo that effective date; it only shifts the argument to what the correct figure was.
A notice sent to the wrong registered address, even for the correct company, restarts nothing – the deadline runs from proven delivery, and a defective delivery cannot be restored by resending it a week later with the same defect. Where the underlying claim is itself close to a limitation period, or where a contractual penalty is running in parallel, the timing of the notice can decide which claim survives to be argued at all.
- Claim undisputed, contract silent on set-off → send notice with proof of delivery → sender's own legal or finance function → before any limitation period on either claim expires
- Claim disputed by the counterparty → resolve the dispute first, or file for a court declaration → sender, with the disputed amount clearly isolated → before the counterparty's own enforcement step, if one is pending
- Contract excludes set-off expressly → set-off notice will not hold → sender must use a different remedy, such as a penalty claim or termination → immediately, before relying on set-off in any correspondence
The same delivery discipline applies to a defect notice under the same contract: both are unilateral declarations whose legal effect depends on the counterparty actually receiving them, not on the sender's good faith belief that they did.
What must the notice and its supporting file contain?
The notice itself has to identify both claims precisely – the contract, the invoice or the obligation, the amount and the date each became due. A notice that simply states "the amounts are set off" without identifying which claim offsets which is open to challenge on the basis that no valid declaration was ever made.
A Dutch counterparty lost the practical benefit of set-off after its supporting invoices were filed without the underlying contract attached, a gap the other side's advisor identified within weeks (summer 2025). The claim itself was sound; the file supporting it was not.
- The contract or order confirmation establishing each claim
- Invoices or equivalent documents showing the date each claim became due
- Proof of delivery of the notice – postal tracking, courier record, or acknowledged email
- Any prior correspondence disputing either claim, including defect notices
- Corporate documents confirming who signed the notice on behalf of each party
- A record of any contractual penalty clause that might apply instead of, or alongside, set-off
A set-off notice without a delivery record is a private opinion, not a legal act.
Where a parent company's finance team wants to understand why a related penalty claim filing gets stuck on much the same documentary gap, the pattern is the same one described here: the claim exists, the file proving it does not.
Before a set-off notice is sent, the safer question is whether the file behind it would survive a challenge.

The report does not decide the dispute; it establishes what the documents actually show.
Act, wait, or stop: what to decide now
Acting now is right where both claims are undisputed, the contract does not exclude set-off, and no limitation period or enforcement step is imminent. Waiting is defensible only where the counterparty's own claim is genuinely still being negotiated and a premature notice would remove that leverage. Stopping – choosing a contractual penalty claim or a termination instead of set-off – is the right call wherever the contract excludes set-off expressly or where the underlying claim is contested on its merits, not just on its timing.
Waiting past the point where the counterparty has already initiated insolvency proceedings changes the claim's ranking, and a ranking, once fixed in that proceeding, does not move back regardless of how sound the set-off argument would otherwise have been.
What cannot be established from the contract and the delivery record alone: whether a court will treat a disputed claim as sufficiently certain to support set-off, and whether the counterparty holds a competing right of retention that was never put in writing. Those questions depend on argument, not on documents, and LISTINA's report states where that line runs rather than guessing past it.

Frequently asked questions
What does set-off notice cost in time?
The notice itself can be drafted quickly once the two claims and their supporting documents are identified. The delay usually sits earlier, in confirming that both claims are due and that the contract does not exclude set-off, and later, in proving delivery – a step that in practice takes longer than drafting the text itself.
Which form is used?
There is no prescribed form. A written declaration identifying both claims precisely, signed by an authorised representative and delivered in a traceable way, is what Czech practice expects. A verbal set-off or an informal message without delivery proof is difficult to rely on later.
Is a representative required?
The notice must be signed by someone authorised to act for the company – a statutory body member or a person holding a power of attorney on file. This is a question of corporate authority, not of legal representation before a court, and it is a common misconception that only a lawyer may sign a set-off notice.
What if the party is abroad?
Delivery still has to be proven, and where the address is outside the Czech Republic the delivery method needs to match what that jurisdiction's postal or courier system can actually confirm. The deadline runs from proven delivery regardless of where the recipient is registered.
