Partial award: resolving part of a claim before the final award

A partial award can resolve a separable part of the dispute with binding effect while other claims or calculation steps remain open. The parties therefore need to identify exactly what has been decided, what follows from it and how the proceedings will continue towards the final award.

This article uses partial award for an intermediate decision within the arbitration. The claim cannot be selected merely for organisational convenience. The decision must have a clearly identifiable subject matter and fit the agreed procedural framework.

The focus is not jurisdiction or a later setting-aside application. It is the separability of the claim, the scope of the decision, the remaining evidence and the proper record of the issues left for the final award.

What a partial award can resolve

A partial award records a separable part of the dispute in a separate decision. This may concern liability in principle or a clearly defined payment component where the remaining amount or further claims can be dealt with separately.

The wording must show whether the tribunal finally decides a partial claim or merely gives a provisional procedural assessment. A reason given for a later final award serves a different function from a separate arbitral award.

The Vienna Rules include final, partial and interim awards within the term award. The parties’ agreement, the applicable rules and the tribunal’s procedural orders remain decisive for the specific conduct of the case.

Define separability and the scope of the decision

Separability means that the decided part can be stated and applied independently without prejudging the issues still open. A mere calculation step is not always enough. The legal and factual boundaries of the ruling are what matter.

The preparation should therefore record which requests are covered, which facts must be established for them and which evidence is needed only for the remainder. The parties should also identify the points that expressly remain open.

This separation prevents the partial award from being mixed with a full evidentiary hearing. It also makes it easier to assess whether the final award properly builds on the points already decided or contains a new and independent ruling.

Binding effect and continuation to the final award

A binding partial decision generally fixes the decided point for the remainder of the proceedings. Its scope follows from the operative part and the subject matter of the ruling. It should not be read more broadly than the award supports.

The arbitration does not automatically end when the partial award is issued. The remaining dispute may require submissions, evidence or calculations. The procedural calendar should therefore state which questions remain and when the parties may address them.

Articles 35 and 36 of the Vienna Rules govern decisions and arbitral awards. A partial award should therefore also be integrated into communications with the parties and into the later final award.

Form and documents for the partial award

The formal requirements of section 606 ZPO apply to an arbitral award. They include written form, the required signatures, reasons, date, seat and service. A partial award should additionally identify the part of the dispute that it decides.

The review should collect the arbitration agreement, procedural rules, earlier submissions, evidence and all procedural orders. It should also include a draft of the proposed operative wording and a list of claims left for the final award.

In a VIAC case, secure the current Vienna Rules, Secretariat communications and tribunal correspondence as well. The contribution on the distinction between seat and hearing venue addresses a different location issue and does not replace review of the award wording.

Distinguish it from jurisdiction and setting aside

A partial award on a claim is different from a decision on the tribunal’s jurisdiction. Calling a decision partial or intermediate also does not by itself answer which later remedies may be available.

This article focuses on the internal course of the arbitration until the final award. Questions about state assistance with evidence belong to the article on court assistance in arbitration. The general preparation of claims, evidence and deadlines is covered by preparing arbitration proceedings.

A reliable assessment requires the complete operative part, reasons, service record and procedural stage to be read together. Individual wording from a letter is rarely enough.

Questions about partial awards

What is a partial award?

A partial award is a separate decision on a clearly separable part of the dispute while other claims or issues remain open.

Does a partial award bind the tribunal later?

The binding effect depends on the specific ruling and its reasons. It concerns the decided point and should not be extended to unresolved claims or merely provisional observations.

Does arbitration end with a partial award?

No. If other issues remain, the proceedings continue with submissions, evidence or calculations and end with a final award.

Next step

Contract, arbitration clause, correspondence and deadlines should be collected. It can then be assessed whether negotiation, preservation or arbitration is central.
