France Reforms Its Arbitration Law in 2026: What It Means for Cross-border Construction Disputes

France reforms its arbitration law in 2026 through the most ambitious overhaul since the landmark 2011 decree, consolidating the scattered arbitration provisions of the Code of Civil Procedure into a standalone, unified Arbitration Code. For parties to cross-border construction contracts, where Paris has long served as the default seat for major infrastructure and EPC disputes, the practical consequences are significant, touching everything from tribunal constitution and interim relief to set-aside strategy and enforcement of awards. The draft decree was circulated for public consultation with a deadline of 20 January 2026, and the French government has targeted promulgation of the unified Code for summer 2026.

This guide unpacks every material change, explains how it reshapes construction arbitration in France, and provides an actionable checklist so that in-house teams and external counsel can update their contracts and dispute-resolution playbooks now.

Executive Summary: Why the 2026 Reform Matters for Construction Parties

The French arbitration reform 2026 is not a minor tune-up. It represents a structural consolidation of domestic and international arbitration rules into a single legislative instrument, the Arbitration Code France practitioners have long called for. The move is designed to modernise procedural safeguards, clarify the boundaries of court intervention, and reinforce Paris’s position as a world-leading seat at a time when rival jurisdictions (London, Singapore, Germany) are updating their own frameworks.

For construction arbitration France disputes, typically high-value, document-heavy, and multi-party, the reform introduces changes to arbitrator appointment and disclosure obligations, broadens recognition of emergency arbitrator relief, and refines the grounds and timetable for setting aside awards. Industry observers expect the combined effect to be a faster, more predictable arbitral process with clearer rules on court support.

Key dates to note: the draft decree arbitration France public consultation closed on 20 January 2026, and the unified Code is targeted for enactment in summer 2026. Parties with existing French-seated clauses should begin their contract-audit cycle immediately. Those negotiating new construction contracts should factor the forthcoming changes into seat-selection and dispute-resolution drafting.

What the Unified Arbitration Code Will Change

Until 2026, French arbitration law sat within Book IV of the Code of Civil Procedure (Articles 1442–1527), split across titles governing domestic arbitration and international arbitration. The draft decree proposes extracting these provisions, updating them, and housing them in a dedicated Arbitration Code. The reform touches six core areas that directly affect construction disputes.

Scope: Domestic vs International Arbitration

The unified Code retains the fundamental distinction between domestic and international arbitration but clarifies the criteria for categorisation. Under current law, an arbitration is “international” where it involves the interests of international trade, a deliberately broad formulation drawn from case law. The reform is expected to codify this test more precisely, reducing satellite litigation over jurisdictional characterisation. For cross-border construction projects, where a French main contractor engages foreign subcontractors or procures materials internationally, the clearer definition should remove ambiguity about which procedural regime applies.

Party Autonomy and Mandatory Rules

The draft decree reinforces party autonomy as the organising principle for international arbitration while tightening certain mandatory procedural safeguards. Parties remain free to choose institutional or ad hoc arbitration, select the applicable procedural rules, and agree the language and place of hearings. However, the reform introduces mandatory minimum standards for arbitrator independence disclosures and due-process protections that cannot be waived by agreement. Construction contracts with bespoke procedural protocols should be reviewed to ensure compatibility with these new mandatory provisions.

Arbitrator Powers and Obligations

The Code is expected to expand the arbitrator’s express powers to order provisional and conservatory measures, grant anti-suit relief (in international cases), and manage evidence production orders. In parallel, arbitrators will face enhanced disclosure obligations covering conflicts of interest, prior appointments, and third-party funding relationships. For construction tribunals, which routinely deal with applications for interim payment, preservation of evidence on building sites, and joinder of subcontractors, the broader toolkit is a practical advantage.

Interim Measures and Emergency Arbitrator Recognition

One of the most anticipated changes is the formal recognition of emergency arbitrator decisions within French law. The current framework is silent on emergency arbitrators, leaving enforcement to depend on creative arguments and supportive case law. The reform is expected to give emergency arbitrator orders the same provisional enforceability as tribunal-ordered interim measures, subject to a streamlined exequatur procedure. Construction parties frequently need urgent relief, to preserve evidence before demolition, to prevent calls on performance bonds, or to order continued access to a site, and statutory recognition removes a layer of uncertainty.

Court Intervention

The reform recalibrates the relationship between arbitral tribunals and the juge d’appui (the support judge). While courts retain their role in appointing arbitrators when party-agreed mechanisms fail and in granting interim relief before or during proceedings, the draft decree narrows the grounds on which courts may intervene in the substance of the arbitration. The likely practical effect will be fewer satellite court applications during the life of a construction arbitration, which is especially valuable in disputes where delay compounds cost overruns on active building projects.

Key Statutory Text Changes (Practical Effect)

• Conflict-of-interest disclosures. Mandatory, continuous disclosure obligation on arbitrators throughout the proceedings, aligned with IBA Guidelines best practice.
• Third-party funding transparency. Parties required to disclose the existence (though not necessarily the terms) of third-party funding arrangements, relevant in construction claims where funders back delay or defects claims.
• Consolidation of related arbitrations. Clearer procedural pathway for consolidating related arbitrations arising from the same construction project, addressing the perennial multi-contract problem in infrastructure disputes.
• Remote hearings. Express recognition of remote and hybrid hearings as procedurally valid, with safeguards for due process.
• Reasoned awards. Codification of the requirement for reasoned awards in international arbitration, reducing set-aside risk on insufficiency-of-reasons grounds.

Timeline: From Consultation to Enactment of the Arbitration Code France 2026

Understanding the legislative calendar is essential for timing contract audits, pending claims, and new dispute-resolution clauses. The table below consolidates the key milestones of the French arbitration reform 2026.

Industry observers expect that the transitional regime will preserve the application of existing rules to arbitrations already commenced before the promulgation date, but the precise cut-off, whether it applies from the date of the request for arbitration or the constitution of the tribunal, will only be confirmed on publication of the final text.

Procedure and Conduct of Arbitrations Under the New Code

The reform recasts several procedural building blocks that are particularly consequential for construction arbitration France disputes, where proceedings are often long, documentary, and involve multiple parties.

Appointment and Challenge of Arbitrators

The draft decree proposes tightening the procedural framework for appointing arbitrators in multi-party arbitrations, a common scenario in construction, where employers, contractors, subcontractors, and engineers may all be involved. Where the parties cannot agree on a method of appointment, the juge d’appui retains jurisdiction, but the reform introduces accelerated timelines for court-assisted appointments to prevent the procedural delays that have historically plagued multi-party construction cases.

Arbitrator challenges will follow a clearer procedural pathway: a mandatory disclosure obligation triggers a defined window for challenge, and the grounds for challenge are aligned more closely with international standards (lack of independence or impartiality, as assessed against objective criteria). Early indications suggest this will reduce tactical challenge applications that are sometimes used in construction disputes to delay proceedings.

Interim Measures and Emergency Relief

As noted above, the formal recognition of emergency arbitrator decisions is a headline change. Beyond emergency relief, the reform also clarifies the tribunal’s power to grant a wider range of interim measures, including orders for the preservation of evidence on construction sites, anti-dissipation injunctions, and orders requiring a party to maintain the status quo (for instance, not to demolish a disputed structure). These measures may be enforced through the French courts via the streamlined exequatur route.

Evidence and Hearing Management

The new Code is expected to codify best practices on document production, expert evidence, and hearing management that have emerged in institutional arbitration rules. This includes express provisions authorising tribunals to order targeted document production (avoiding the excesses of common-law-style discovery), to appoint tribunal experts, and to conduct hearings remotely. For construction arbitrations, which typically involve vast volumes of project records, delay analyses, and quantum expert reports, the codification of these powers gives tribunals a clearer mandate to manage proceedings efficiently.

Courts’ Role: Support, Supervision and Review Under the French Arbitration Reform 2026

France’s arbitration-friendly judiciary has long been a selling point for Paris seat arbitration 2026 and beyond. The reform preserves the supportive philosophy but introduces adjustments that construction parties should understand.

When to Litigate in French Courts vs the Arbitral Tribunal

The draft decree maintains the principle that French courts will assist, not supplant, the arbitral process. Courts retain jurisdiction over three primary functions: appointment of arbitrators where party mechanisms fail, granting of provisional measures before or in parallel with the arbitration, and post-award review through set-aside proceedings. However, the reform narrows the scope for interlocutory court applications once the tribunal is constituted, directing parties to seek relief from the tribunal first. The practical consequence for construction parties is that tactical court applications mid-arbitration, sometimes used to slow proceedings or create parallel pressure, are likely to become harder to sustain.

Practical Litigation Hooks for Construction Disputes

Despite the narrower scope, French courts will continue to play a vital supportive role in construction cases. Common scenarios where court assistance remains available include obtaining evidence from third parties not bound by the arbitration agreement (such as sub-subcontractors or insurers), enforcing interim measures ordered by the tribunal or an emergency arbitrator, and granting protective attachments over assets in France. In-house teams managing large infrastructure projects should map these hooks into their dispute-resolution strategy from the outset, rather than discovering them mid-dispute.

Set-Aside Procedure: New Grounds and Strategy for Construction Arbitration France

The ability to set aside an award rendered in France is governed by a closed list of grounds, and the reform proposes to refine both the substance and the procedure of annulment applications. For construction parties, whether seeking to challenge an adverse award or defending a favourable one, the changes demand close attention.

The draft decree is expected to maintain the existing grounds for setting aside international awards (broadly mirroring those in Article 1520 of the current Code of Civil Procedure), while clarifying procedural requirements and introducing tighter time limits. The likely practical effect will be a more disciplined set-aside process, reducing the duration and cost of post-award litigation.

Key procedural changes to anticipate for set aside award France 2026 applications:

• Streamlined filing requirements. Applicants will need to identify the specific ground(s) relied upon and supporting evidence at the point of filing, reducing the scope for vague or speculative challenges.
• Time limits. The one-month deadline for filing a set-aside application (from notification of the award) is expected to be retained, but the reform may introduce stricter rules on extensions and the admissibility of late evidence.
• Due-process review. The grounds relating to procedural irregularity (failure to respect adversarial proceedings, equality of arms) are expected to be clarified, providing more predictable standards for construction disputes where procedural management is often complex.
• Public-policy review. The scope of ordre public review, already narrowly construed by French courts, is not expected to widen, maintaining France’s pro-enforcement stance.

For respondents defending an award in a construction arbitration, the reform reinforces the importance of maintaining a clean procedural record throughout the arbitration. Any due-process objections should be raised promptly and recorded in the procedural minutes; failure to do so may preclude reliance on those objections in set-aside proceedings.

Enforcement in France and Cross-Border Implications

Obtaining a favourable award is only half the battle in construction disputes, enforcement is where value is realised. The reform updates the domestic enforcement framework while preserving France’s strong pro-enforcement posture under the New York Convention.

To enforce an arbitral award in France, the successful party must obtain an exequatur (enforcement order) from the Tribunal judiciaire of Paris for international awards. The draft decree proposes to streamline the exequatur process by clarifying documentation requirements and reducing procedural bottlenecks. For construction creditors holding large awards, where the losing party may attempt to dissipate assets, the faster enforcement pathway is a meaningful improvement.

Cross-border enforcement remains governed by the 1958 New York Convention, to which France is a party. The reform does not alter France’s Convention obligations but brings domestic procedural rules into closer alignment with international best practice, making it easier to present French-seated awards for enforcement in other Convention states.

Practical checklist for enforcement evidence in construction cases:

• Certified copy of the award. Ensure the award is duly signed, dated, and includes reasons.
• Original arbitration agreement. Or a certified copy, demonstrating the jurisdictional basis for the award.
• Translation. If the award is not in French, a certified translation by a sworn translator is required.
• Evidence of notification. Proof that the award was properly notified to the losing party.
• Asset identification. For protective attachments, identify the debtor’s assets in France (bank accounts, property, receivables from French project employers).
• Urgency application. Where dissipation risk exists, consider applying for a saisie conservatoire (protective attachment) simultaneously with the exequatur request.

Practical Checklist for Construction Contracts and Clauses

The reform creates an opportunity, and an obligation, for construction parties to review and update their standard arbitration clauses. Whether negotiating a new EPC contract or reviewing existing framework agreements, the following checklist addresses the key drafting points affected by the 2026 changes to paris seat arbitration 2026 practice.

• Seat clause. Confirm that Paris (or another French city) is expressly designated as the seat. A clear seat clause removes ambiguity about which lex arbitri applies and ensures the new Arbitration Code governs.
• Institutional vs ad hoc. Decide whether to specify ICC, LCIA, or another institution, or to use ad hoc arbitration under the new Code’s default rules. The reform strengthens the default procedural framework, making ad hoc arbitration more viable for parties wishing to avoid institutional fees.
• Multi-tier dispute resolution. Review any pre-arbitral steps (mediation, adjudication, dispute boards) for compatibility with the new mandatory provisions. Ensure time bars and escalation mechanisms align with the reformed procedural calendar.
• Emergency arbitrator clause. Expressly opt in or out of emergency arbitrator provisions. The reform gives emergency arbitrator decisions statutory recognition, so an explicit opt-out is now necessary if the parties prefer to rely solely on court-ordered interim relief.
• Interim-relief clause. Consider whether to authorise the tribunal to grant specific forms of relief relevant to construction (site access orders, bond-call injunctions, evidence preservation). The broader statutory powers under the new Code make these clauses more enforceable.
• Multi-party and consolidation provisions. In contracts involving chains of subcontractors or joint ventures, include express provisions for joinder and consolidation, taking advantage of the reform’s clearer procedural pathway.
• Governing law of the arbitration agreement. Specify that the arbitration agreement is governed by French law, so the new Code applies both to the procedure and to the validity and scope of the agreement itself.

Sample Clause Language (Before and After Reform)

Pre-reform typical clause:

“Any dispute arising out of or in connection with this contract shall be finally settled by arbitration in Paris under the ICC Rules. The arbitration shall be conducted in English.”

Post-reform recommended clause:

“Any dispute arising out of or in connection with this contract, including any question regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration seated in Paris, France, under the ICC Rules of Arbitration. The arbitration agreement shall be governed by French law. The tribunal shall have power to grant interim and conservatory measures, including emergency relief. The language of the arbitration shall be English. The parties expressly consent to the joinder of any third party bound by a compatible arbitration agreement arising from the same project.”

The updated clause expressly addresses the governing law of the arbitration agreement, interim measures, emergency relief, and joinder, all areas where the French arbitration reform 2026 creates new statutory support.

Comparative Snapshot: France vs Other Recent Arbitration Reforms

France is not reforming in isolation. Several major arbitration seats have recently updated or are in the process of updating their arbitration legislation. The table below offers a comparative snapshot to help construction parties assess how paris seat arbitration 2026 stacks up against competing jurisdictions.

Industry observers expect France’s reform to consolidate its lead among civil-law jurisdictions for international construction arbitration, particularly for disputes involving parties from the MENA region, Sub-Saharan Africa, and Asia where French legal traditions and treaty networks provide enforcement advantages.

Conclusion and Action Plan: Six-Month Checklist for In-House Teams

As France reforms its arbitration law in 2026, construction parties cannot afford a wait-and-see approach. The unified Arbitration Code will reshape the procedural landscape for Paris-seated disputes, and the transition window between promulgation and the first cases under the new rules is the time to act. The following six-month action plan provides a structured path forward.

1. Audit existing contracts. Identify all agreements containing French-seated arbitration clauses and assess whether the clause language is compatible with the new Code’s mandatory provisions.
2. Engage local counsel. Instruct counsel in France to provide a gap analysis between current clause templates and the requirements of the reform.
3. Update standard clause templates. Incorporate the post-reform recommended language covering emergency arbitrator relief, interim measures, joinder, and governing law of the arbitration agreement.
4. Reassess seat choices for new contracts. For projects currently in procurement, evaluate whether Paris remains the optimal seat in light of the reforms, or whether the changes make it an even stronger choice than before.
5. Prepare enforcement and set-aside templates. Develop internal playbooks for post-award strategy under the new Code, including evidence checklists, timeline maps, and protective-attachment procedures.
6. Monitor transitional provisions. Once the final text is published, confirm whether pending arbitrations are subject to the old or new rules and adjust strategy accordingly.
