How to Choose and Start a Commercial Dispute in Switzerland (2026): Swiss International Commercial Courts vs Arbitration, Step‑by‑step

The procedure for Swiss international commercial courts in 2026 gives general counsel, founders and dispute‑resolution managers a new, English‑language forum for cross‑border commercial claims, one that sits alongside well‑established institutional arbitration under the updated Swiss Rules. Following the revision of the Swiss Civil Procedure Code (CPC/ZPO) that took effect on 1 January 2025, cantons including Zurich and Bern have moved to establish dedicated international commercial chambers that accept filings and conduct hearings entirely in English. This guide walks through every decision point, filing step, document requirement, deadline and cost estimate a claimant needs to know before instructing counsel, and explains when arbitration may still be the stronger choice.

Overview of the Process and Who It Applies To

Switzerland’s international commercial courts are state courts with a specialist mandate. They hear cross‑border commercial disputes above a defined value threshold, apply Swiss procedural law (the CPC/ZPO) and, critically, permit English proceedings in Switzerland from pleadings through to judgment. The courts sit within existing cantonal structures but operate with judges experienced in international transactions, enabling faster case management than standard civil chambers.

The alternative remains institutional arbitration, most commonly administered by the Swiss Chambers’ Arbitration Institution under the Swiss Rules (updated for 2026). Both routes are credible, but they diverge on enforceability, confidentiality, interim measures, costs predictability and procedural flexibility. The choice of forum shapes every subsequent step, so it must be resolved before any filing is prepared.

Quick Decision Matrix: Court vs Arbitration

Industry observers expect the court route to gain market share for Lugano‑zone disputes where public enforcement is straightforward, while arbitration will remain dominant where New York Convention enforceability in non‑Lugano states is essential or where confidentiality is paramount.

Eligibility and Prerequisites for the Procedure for Swiss International Commercial Courts 2026

Not every commercial claim qualifies for a Swiss international commercial court. Claimants must satisfy a series of cumulative tests before the court accepts jurisdiction. Failing any one of these tests means the claim must proceed in a standard cantonal court or, if an arbitration clause exists, before a tribunal.

Jurisdictional Tests: Commercial Nature, Minimum Value and Domicile

The dispute must be commercial in nature: it must arise from the business activity of at least one party. Pure consumer, employment, tenancy and family‑law claims are excluded. The revised CPC empowers cantons to set a minimum value in dispute. Under Zurich’s implementing legislation, the threshold is CHF 100,000. Bern has adopted the same floor. Claims below this amount must be brought in ordinary cantonal courts.

At least one party must be domiciled or have its registered seat outside Switzerland, or the parties must have expressly agreed to the jurisdiction of the international commercial court. This international‑nexus requirement prevents purely domestic disputes from occupying specialist chambers.

Party Agreement and Consent

Jurisdiction can arise in two ways. First, the parties may include a forum‑selection clause in their contract designating a specific cantonal international commercial court. Second, where no prior clause exists, the defendant may submit to jurisdiction by appearing and pleading on the merits without objecting. Tacit submission is sufficient under the CPC, but relying on it carries risk, if the defendant objects at the outset, the court must decline jurisdiction absent another basis.

Claimants should review existing contracts for both forum‑selection and arbitration clauses. An arbitration clause generally takes precedence; the court will decline jurisdiction if a valid arbitration agreement exists and the respondent raises the objection in time.

Exclusions and Mandatory Jurisdiction Rules

Certain categories of dispute are excluded regardless of the amount at stake: insolvency and debt‑enforcement proceedings, intellectual‑property registration disputes, and claims subject to mandatory exclusive jurisdiction under Swiss or international law. Mandatory consumer‑protection and employment‑law fora also override any choice‑of‑court agreement.

Before filing, confirm every element using the checklist below.

If any answer is “No,” the international commercial court route is unavailable. Consider standard cantonal proceedings or arbitration instead.

Step‑by‑Step Procedure for Filing and Conducting Proceedings

Once eligibility is confirmed, the procedure for Swiss international commercial courts in 2026 follows a structured sequence. The table below summarises each step, the responsible actor and expected duration before the detailed sub‑steps that follow.

Step 1, Pre‑Filing Checklist and Forum Decision

Run the eligibility checklist above. Confirm whether a valid arbitration clause exists and, if so, whether it can be waived by agreement. Assess enforcement geography: if the defendant’s assets are in Lugano Convention states, the court route offers direct enforceability; if assets sit in non‑Lugano jurisdictions, arbitration under the New York Convention is often more practical. Agree the litigation budget, identify key evidence and appoint Swiss‑admitted counsel.

Step 2, Filing the Claim

To file a claim in a Swiss international commercial court, counsel prepares and submits the following to the relevant cantonal registry:

1. Statement of claim, sets out the factual and legal basis, the relief sought and the value of the claim. Under the CPC, all essential facts must be pleaded and each factual allegation must be linked to an identified item of evidence (the “evidence anchor” rule).
2. Request for English proceedings, must be included with the statement of claim if the claimant wishes proceedings conducted in English.
3. Supporting documents, contracts, invoices, correspondence and any expert reports (see the full documents table in the next section).
4. Power of attorney, authorising counsel to act, notarised where required by canton rules.
5. Filing fee payment, pay the court filing fee upon submission. The registry will not process the claim until the fee is received.

Once filed, the court registry issues an acknowledgment and serves the claim on the defendant. For international service, the court applies the Hague Service Convention or applicable bilateral treaties. Service timelines vary significantly, expect one to six weeks depending on the destination state.

Step 3, Early Interim Measures and Emergency Relief

Interim measures can be requested before or simultaneously with the statement of claim. Under Articles 261–269 CPC, a claimant may apply for conservatory measures, freezing orders, or provisional performance. Ex parte applications, made without notifying the defendant, are available where prior notice would defeat the purpose of the measure.

The applicant must demonstrate: (a) a prima facie case on the merits, (b) a threat of not easily reparable harm, and (c) proportionality. Courts in Zurich and Bern have demonstrated the capacity to issue emergency orders within hours of filing in urgent cases. The respondent will be given an opportunity to be heard shortly after the order is made, and the court may require the applicant to post security for potential damages.

In arbitration under the Swiss Rules, an emergency arbitrator can be appointed before the tribunal is constituted to grant interim relief. However, any resulting order requires a state‑court application to be enforceable against third parties or assets.

Step 4, Case Management and Disclosure

After service is completed and the defendant has filed its answer (typically within the deadline set by the court, often 30 days), the judge convenes a case management conference. At this conference, the court sets the procedural timetable: deadlines for second‑round pleadings, document production, witness‑statement exchanges and expert evidence.

Swiss procedure does not provide for US‑style discovery. Document production is limited to specifically identified documents that a party can show are relevant and in the other party’s possession. In arbitration, the parties often adopt the IBA Rules on the Taking of Evidence, which provide a broader (though still controlled) framework for document requests.

Step 5, Trial, Hearing and Judgment

Hearings are conducted in English where that language has been requested and accepted. The court hears oral testimony from witnesses and party representatives, receives expert evidence and allows oral closing submissions. All proceedings are recorded. Judgments are issued in writing, typically within two to twelve weeks after the hearing, depending on complexity.

Judgments of a Swiss international commercial court are immediately enforceable in Switzerland upon service. No separate enforcement order is required domestically.

Step 6, Post‑Judgment Remedies and Enforcement

The losing party may appeal to the Federal Supreme Court on questions of law. The appeal must be filed within 30 days of notification of the reasoned judgment. The Federal Supreme Court does not re‑examine facts. For enforcement of Swiss judgments abroad, the Lugano Convention provides for recognition and enforcement across EU and EFTA member states without a review of the merits. Outside the Lugano zone, enforcement depends on bilateral treaties or domestic recognition rules of the target state.

Required Documents and Information

Preparing a complete filing package at the outset reduces delays and avoids court requests for supplementary materials. The table below lists the core documents required when you file a claim in Switzerland through an international commercial court, together with practical notes on format and authentication.

For English proceedings, all documents originally in another language should be accompanied by a certified translation. The court may accept uncertified translations of ancillary documents but will require certified versions for key contractual and evidentiary materials. Prepare an indexed evidence bundle, Swiss courts expect each factual allegation in the statement of claim to reference a specific numbered exhibit.

Timeline and Key Deadlines

Speed is one of the main attractions of the new procedure for Swiss international commercial courts in 2026. The table below consolidates indicative calendar times and flags statutory deadlines that counsel must verify with the relevant cantonal court before filing.

Early indications suggest that Zurich’s international commercial chamber aims to issue first‑instance judgments within 12 to 18 months of filing for standard‑complexity matters. Emergency interim measures operate on a much compressed timetable, with orders routinely issued the same day in genuinely urgent cases.

Costs, Fees and Tax Considerations

Costs vary by canton, claim value and case complexity. The table below provides indicative ranges. All figures are estimates and should be verified with the relevant cantonal court registry or institutional fee schedule before budgeting.

Swiss court proceedings generally follow a “loser pays” principle for court costs and a contribution toward the prevailing party’s legal fees. The court determines the cost allocation in the judgment. In arbitration, the tribunal has broader discretion on cost allocation and may order full indemnity in appropriate cases.

What Changes in 2026: CPC Revision, Swiss Rules and Court Rollouts

Three developments converge to reshape the procedure for Swiss international commercial courts in 2026 and the broader dispute‑resolution landscape:

1. CPC revision (effective 1 January 2025). The revised Code of Civil Procedure introduced Article 6 para. 4bis CPC, which formally authorises cantons to establish international commercial courts with the power to conduct proceedings in English. This provision created the legislative foundation that Zurich and Bern have since acted upon.
2. Cantonal court rollouts (2025–2026). Zurich launched its international commercial chamber within the Handelsgericht in 2025 and has been accepting English‑language filings since that date. Bern has followed with its own implementation. Other cantons, including Geneva, have considered similar steps. Counsel should confirm the operational status of each cantonal chamber before filing, as implementation timelines continue to evolve.
3. Swiss Rules 2026. The Swiss Chambers’ Arbitration Institution has updated its institutional rules, with amendments affecting emergency‑arbitrator procedures, consolidation of related arbitrations, and joinder of additional parties. These changes alter the comparison calculus: emergency relief in arbitration is now more streamlined, but still requires court assistance for enforcement against non‑parties.

The likely practical effect of these combined reforms is a period of forum competition. Claimants with Lugano‑zone enforcement needs and no confidentiality concerns will increasingly favour state commercial courts. Claimants needing worldwide enforceability or privacy will continue to choose arbitration. Practitioners should verify the current status of cantonal implementations with the Swiss Federal Office of Justice and the relevant cantonal court registries before committing to a forum.

Common Pitfalls and How to Avoid Them

• Filing in the wrong forum. An existing arbitration clause in the underlying contract will override a forum‑selection agreement for the commercial court. Review all relevant contracts, including general terms and conditions, for arbitration clauses before filing.
• Missing the value threshold. Claims below CHF 100,000 are ineligible. Where multiple claims exist against the same defendant, confirm whether aggregation rules apply under cantonal practice before assuming the threshold is met.
• Neglecting notarisation of the power of attorney. Some cantons require notarised powers of attorney for foreign‑domiciled claimants. A defective power of attorney can delay proceedings by weeks.
• Delayed interim measures application. Waiting until after the statement of claim is served to seek interim relief can give the defendant time to dissipate assets. File emergency applications at the earliest possible stage.
• Wrong service method. Attempting informal service on a foreign defendant (e.g., by email) will not satisfy CPC or Hague Convention requirements. Use only the service channels specified by the court and applicable treaties.
• Under‑estimating translation requirements. Courts conducting English proceedings will still require certified translations of key foreign‑language documents. Budget for translation costs and allow time in the preparation schedule.
• Poor evidence indexing. Swiss courts expect every factual allegation to be linked to a numbered exhibit. An un‑indexed evidence bundle slows case management and may result in allegations being treated as unsubstantiated.
• Ignoring the appeal window. The 30‑day appeal deadline to the Federal Supreme Court is strictly enforced. Failure to file within this period makes the judgment final and unappealable.
• Assuming US‑style discovery is available. Swiss procedure does not permit broad document requests. Prepare evidence proactively rather than relying on post‑filing discovery motions.
• Overlooking enforcement geography. A Swiss court judgment is directly enforceable under the Lugano Convention within EU and EFTA states, but may require separate recognition proceedings outside that zone. Map the defendant’s asset locations before selecting the forum.
