Correcting or supplementing an arbitral award: using the four week window
14 August 2026 | Mag. Bernhard Brandauer, Rechtsanwalt
Correcting or supplementing an arbitral award under section 610 ZPO: four week window and limits.
Correcting or supplementing an arbitral award: using the four week window addresses a narrow point in Austrian arbitration. The article explains the issue on the basis of the verified ZPO source and shows which documents should be secured first.
The review question is: After the award, is the issue correction, interpretation, supplementation or setting aside? The source basis is § 610 ZPO. The article is general information and does not replace review of the individual file.
The article is deliberately not a general arbitration guide. It focuses on the limited request to the arbitral tribunal after receipt of the award rather than setting aside and the practical procedural risk behind it.
Which point should be reviewed first?
The short check structures your starting point. The result is transmitted only if you actively submit the form.
Is the full award available and is the receipt date documented?
Prepare prompt detailed review
The starting data is available. Clause, procedural stage, deadlines and objective should now be checked against the documents.
- Secure the receipt date
- Describe the error precisely
- Separate setting aside from supplementation
Organise documents first
Missing documents make the assessment uncertain. A short chronology with contract, correspondence and proof is useful.
- Secure the receipt date
- Describe the error precisely
- Separate setting aside from supplementation
Secure first orientation
Before tactical steps, clarify whether arbitral tribunal, state court, settlement or enforcement is central.
- Secure the receipt date
- Describe the error precisely
- Separate setting aside from supplementation
What the issue is about
After an arbitral award, parties often notice a calculation error, typing error or unresolved claim first. Section 610 ZPO provides a specific tool that must not be confused with setting aside.
For practice, the procedural position must be separated first. Contract, clause, correspondence, deadlines and steps already taken should then be ordered before a response or application is prepared.
Legal basis and review step
The RIS source for section 610 ZPO provides for an application within four weeks after receipt of the award. It distinguishes correction, agreed interpretation and a supplementary award for claims not decided.
The source does not create an automatic answer for every case. Clause wording, seat, procedural rules and current stage must be read together.
Typical preparation mistake
A common mistake is calling every dissatisfaction a correction. Section 610 ZPO does not allow a new merits decision on points already decided.
A short chronology is useful. It should show not only dates but also which document was transmitted and how the other side reacted.
Difference from other arbitration issues
This article deepens one practical scenario. The wider structure is explained on the topic pages about arbitration clauses, preparing arbitration and enforcing arbitral awards.
The separation avoids duplicate core content. The purpose here is quick classification of a narrow problem based on the verified ZPO source.
What to prepare for an enquiry
Helpful documents are the contract, arbitration clause, latest letters, proof of service, deadlines, a short chronology and the intended commercial outcome.
Important documents are proof of receipt, the full award, list of errors, unresolved requests and whether an interpretation agreement exists.
Common questions on arbitration
How long is the application period under section 610 ZPO? Unless the parties agreed another period, section 610 ZPO provides four weeks from receipt of the arbitral award.
Can the point be corrected later? That depends on the procedural stage. Some objections must be raised early. Other points can be corrected or reviewed only within narrow limits after the award.
Which documents should be sent first? Send contract, arbitration clause, amendments, proof of service, deadlines and a short chronology. Confidential details should be coordinated first.
Next step
Contract, arbitration clause, correspondence and deadlines should be collected. It can then be assessed whether negotiation, preservation or arbitration is central.
