Set-off against an insolvent counterparty: cost and likely outcome depends almost entirely on one question: does the trustee accept that the two claims were genuinely independent and pre-existing, or does the trustee read the arrangement as an attempt to improve your position ahead of the bankruptcy. Where the claims are real and predate the filing, set-off usually holds. Where it was engineered at the last minute, it is usually reversed.
Who this concerns
This situation arises whenever a creditor of a company that later becomes insolvent is, at the same time, indebted to that same company. A supplier who also bought goods or services from the counterparty, a landlord sitting on a tenant's deposit, a contractor holding retention money against a claim for unpaid works, or a group company with a running intercompany account are the recurring configurations. In each case there are two claims running in opposite directions, and the question is whether they can be netted into one net position rather than paid in full on one side and claimed as an unsecured debt on the other.
This sits within Lodline's insolvency and restructuring practice, where set-off disputes are one of the recurring flashpoints once a counterparty stops paying and a bankruptcy filing becomes likely or has already happened. It concerns any commercial creditor with a mutual position, not just banks or secured lenders. A creditor with no reciprocal debt to the estate gains nothing from this analysis; for that party, the claim is simply lodged and ranked in the ordinary way.
What the law says
Under Swedish law as it currently stands, a creditor may in principle set off a claim it holds against a bankrupt company against a claim the bankruptcy estate holds against that same creditor, provided the two claims are mutual, existed before the bankruptcy decision, and are of a kind capable of being set off against each other under general civil law principles. The trustee administering the estate is the party who assesses whether that position is accepted, and the trustee's acceptance is not automatic.
Swedish insolvency practice generally allows the estate to challenge an arrangement that was put in place shortly before the bankruptcy filing with the specific purpose of creating or strengthening a set-off position. If a creditor rushed to buy a claim against the debtor, or restructured an existing relationship, once financial distress became apparent, the estate can treat that step as an attempt to obtain preferential treatment and refuse to honour the resulting set-off. The closer the timing sits to the actual filing, the harder that position is to defend.
Where the counterparty sits inside a group with a foreign parent, an additional layer appears. The parent's own exposure and behaviour before the filing can become relevant to how the trustee views the group's conduct, and questions of director liability with a foreign parent sometimes surface alongside the set-off dispute itself, particularly where intercompany balances were adjusted in the run-up to the filing. A set-off claim rarely travels alone in a group insolvency; it tends to arrive with a parallel question about who authorised the adjustments.
How it works in practice
Establishing mutuality
The first test is whether the two claims genuinely run between the same two parties in their own right. A claim held by a subsidiary cannot generally be set off against a debt owed by a different group entity, even where the companies operate as one commercial unit. Group accounting conventions do not override the legal requirement that the parties to both claims are identical.
Timing of the two claims
Both claims must have existed before the bankruptcy decision. A claim that only arises afterwards, for example a claim for damages triggered by the trustee's own conduct during the administration, does not qualify for set-off against a pre-existing debt. The dates on which each obligation became due, and the date the underlying contract was concluded, are the first documents the trustee will ask for.
Notifying the trustee
Set-off is not self-executing. The creditor has to raise it with the trustee, supported by evidence of both claims, rather than simply withholding payment and assuming the position is understood. A creditor who stays silent and later tries to raise set-off as an afterthought during a dispute over the estate's claim starts from a weaker position than one who raised it promptly and in writing.
When the estate disputes set-off
If the trustee disputes mutuality, timing, or the underlying validity of either claim, the matter moves from an administrative exchange to something closer to a contested claim. At that point the creditor needs the same evidence it would need to prove the claim in ordinary litigation: contracts, invoices, delivery records, correspondence confirming acceptance of goods or services, and any prior acknowledgment by the debtor of the amount owed.
Documentation the trustee will ask for
Expect requests for the full contractual history between the parties, ledger extracts showing both sides of the account, evidence that the claim against the debtor was not manufactured or accelerated once distress became visible, and confirmation of the exact date each obligation crystallised. Missing or informal documentation is the single most common reason a set-off claim that should succeed on the merits takes far longer than it needs to.
Group and intercompany balances
Intercompany loans and running accounts are set off far less reliably than ordinary trade debt. Adjustments made to these balances in the months before a filing attract particular scrutiny, because they are the easiest position to engineer from inside a group. Where the counterparty is a listed company, the same period can also trigger separate obligations around disclosure deadlines for listed companies that run in parallel with the insolvency timeline and are worth checking independently.
Foreign counterparties and choice of law
Where the contract giving rise to either claim is governed by a foreign law, or where the counterparty's assets sit outside Sweden, the analysis does not stop at Swedish insolvency mechanics. The governing law of the underlying obligation can affect whether set-off is available at all, and enforcing any resulting position abroad raises its own questions, similar to those that arise on recognition of a Swedish judgment abroad. A set-off that is clean under Swedish law is not automatically effective wherever the counterparty's assets happen to be.
What to check
- The exact date each of the two claims arose, not the date it was invoiced or booked.
- Whether either claim was acquired, assigned, or restructured after the debtor's financial difficulty became known.
- Whether the claims run between the same two legal entities, not between affiliated companies.
- Whether the underlying contracts are governed by Swedish law or a foreign law.
- Whether the trustee has been notified in writing, with supporting documents attached.
- Whether any part of the position depends on an intercompany or group account rather than an ordinary trade debt.
Can set-off be exercised after bankruptcy has been declared?
Set-off can still be raised after the bankruptcy decision, but the underlying claims must have existed before that date. The bankruptcy itself does not create a new opportunity to set off claims that only arose afterwards, and the trustee will check the dates carefully before accepting the position.
What happens if the mutual claims arose at different times before insolvency?
Different dates of origin do not by themselves defeat set-off, provided both claims existed before the bankruptcy decision. What matters more is whether either claim was accelerated, assigned, or otherwise adjusted once the debtor's distress became apparent, since that timing is what the trustee scrutinises most closely.
Does set-off survive if the counterparty's claim was assigned to a third party shortly before insolvency?
An assignment shortly before the filing is one of the situations the trustee is most likely to challenge, particularly if the assignment appears designed to create a set-off position that did not previously exist. Whether it survives depends on the commercial reason for the assignment and how well that reason is documented.
The numbers
No fixed cost or timetable can be quoted for a set-off dispute without knowing the specific facts, and quoting one without a documented basis would be misleading rather than helpful. What drives cost is the number of transactions that need to be reconstructed, whether the trustee disputes mutuality or timing, whether litigation becomes necessary, and how much of the position rests on intercompany records rather than straightforward trade documentation.
The realistic range of outcomes falls into three broad categories. The set-off is accepted in full because the claims are clean, mutual, and clearly predate the filing. The set-off is accepted in part after negotiation, typically where some of the underlying amount is disputed or where documentation only supports a portion of the claimed figure. Or the set-off is refused, and the claim is relegated to an ordinary unsecured position in the bankruptcy, ranked alongside other creditors with no priority.
Where it usually goes wrong
Creditors frequently assume set-off is automatic once both claims exist, and stop actively managing the position because they believe the numbers will simply net out. They do not net out automatically; the trustee has to accept the position, and silence from the creditor is read as a failure to raise it in time.
A second recurring error is timing. Creditors who learn of a counterparty's distress and then move quickly to acquire, assign, or restructure a claim against that counterparty in order to create or improve a set-off position expose themselves directly to challenge. This overlaps closely with the wider question of how we assess asset stripping claims, since a manufactured set-off and a stripped asset are often two sides of the same pre-filing manoeuvre from the trustee's perspective.
A third failure mode is assuming that intercompany netting arrangements survive on the same terms inside a bankruptcy that they had inside the group's own accounting practice. They do not; the trustee is not bound by an internal group convention, only by whether the claims genuinely meet the legal test for mutual, pre-existing obligations between the same two parties.
Finally, creditors dealing with a foreign-law contract sometimes assume Swedish set-off principles apply wholesale to the underlying obligation. Where the contract is governed by a different law, that law can affect whether set-off is available at all, independently of what the Swedish bankruptcy process otherwise permits.
What to do next
This material takes you to the point where the question stops being general and becomes document-specific: whether your particular claims meet the mutuality and timing tests, and whether anything in the transaction history could be read as an attempt to manufacture the position. That assessment requires looking at the actual ledger, contracts, and correspondence with the trustee, not the general mechanics described here.
Where the dispute borders on asset stripping rather than a straightforward set-off, our related analysis of the cost and outcome of asset-stripping claims covers the adjacent question of what a challenge to pre-filing conduct typically involves and what it resolves. If your position sits closer to a genuine, well-documented set-off, the next step is to arrange an assessment call so the specific claims and timing can be reviewed before you commit to a position with the trustee.
