Civil Code conditions
Claims must be mutual, homogeneous and mature for set-off.
Priority prevails
Set-off must not provide individual recovery outside the collective process.
Pre-filing risk
A set-off made before the petition can still be reviewed as a preference.
Four-level review
| Level | Required finding | Warning sign |
|---|---|---|
| Mutuality | Each party is debtor and creditor of the other | A claim belongs to a third party |
| Homogeneity | The result mirrors mutual performance | Money is matched against delivery of an asset |
| Maturity | The active claim is due or lawfully accelerated | Declaration predates Civil Code conditions |
| Bankruptcy | Register and current-payment priority remain intact | One creditor receives more than in the process |
Civil Code Article 410 permits unilateral set-off, but Bankruptcy Law protects collective and proportionate creditor recovery. A set-off valid outside insolvency may therefore be restricted or avoided in bankruptcy.
Workflow
Build the timeline
Map contracts, performance, defaults, the declaration, petition acceptance and procedure dates.
Classify both claims
Separate register and current claims, principal, interest and sanctions.
Compare with priority
Measure actual recovery against the statutory distribution outcome.
Review avoidance periods
Assess preference indicators, knowledge and ordinary-course evidence.
Documents
- contracts creating both claims;
- acts, deliveries, reconciliations and payments;
- set-off declaration or agreement and delivery proof;
- claim calculations at the set-off date;
- EFRSB notices and bankruptcy orders;
- creditor and payment-priority evidence.
📅 Challenging set-off: dates and evidence
Added on 25 October 2026. For a preference challenge, the reference date is the court’s acceptance of the bankruptcy petition, not publication, filing or the bankruptcy declaration. The transaction-review period and the deadline for bringing the challenge are separate issues.
| Article 61.3 period | Check | Illustrative dates |
|---|---|---|
| After petition acceptance or within one month before it, paragraph 2 | A preference under paragraph 1; the date alone does not establish invalidity | If acceptance was on 15 September 2026, set-off on 20 August falls within the one-month period |
| Within six months before acceptance, paragraph 3 | Additional grounds: securing an earlier obligation, changing priority, or knowledge of insolvency or insufficient assets; an interested party faces a rebuttable knowledge presumption | Set-off on 1 July with the same acceptance date is outside one month but within six months |
These examples only locate dates. The legally effective moment of set-off, the claims and applicable exceptions need separate analysis. A calendar month cannot always be replaced with “30 days”, and not every set-off within six months is automatically invalid.
Preparing a position in the dispute
- Attach the petition-acceptance order, set-off document and delivery evidence.
- Calculate each claim separately: basis, origin, maturity, balance and bankruptcy status.
- Explain the alleged advantage and substantiate other creditors’ position. A responding party should provide documents and a calculation, rather than rely solely on good faith.
- For paragraph 3, identify evidence of the additional conditions, such as affiliation, default correspondence or changes in security or priority, explaining each document’s relevance.
- Address avoidance consequences and how the restored claim is pursued under Article 61.6 separately.
How can a written position begin?

Fill in the facts, attach calculations and adapt the relief sought to your procedural status.

FAQ
Can claims be set off during observation?
Only where special bankruptcy restrictions and creditor priority are not breached.
Is a reconciliation act enough?
Usually no; it does not replace a clearly delivered set-off declaration or agreement.
Can current claims be set off?
Current-payment priority and the actual effect must be reviewed separately.
What follows avoidance?
Both obligations are restored subject to Bankruptcy Law Article 61.6.
