Can you include an arbitration clause in a contract with a French customer?

Short answer: yes with a professional customer (B2B), no with a consumer (B2C). The details of drafting and use matter. Here is practical guidance to decide, draft and secure your arbitration clause.

What French law says in 2026

1) Validity in B2B

• Legal basis: an arbitration clause (clause compromissoire) is valid in contracts “concluded in connection with a professional activity” (art. 2061 of the Civil Code, Legifrance — French legislation portal).
• Mandatory written form: the arbitration agreement must be written (art. 1443 of the Code of Civil Procedure). See Book IV — Arbitration (CPC).
• Competence-competence: where a dispute covered by an arbitration clause is brought before a state court, it declines jurisdiction unless the clause is manifestly void or inapplicable (art. 1448 CPC, Legifrance — Arbitration).
• Enforcement of the award: an arbitral award must be declared enforceable through exequatur before compulsory enforcement (Book IV CPC, Legifrance — French legislation portal).
• Practical direction: the “Justice for the 21st Century Act” facilitated arbitration in professional contexts by clarifying and modernising the framework (EFL — legal publishing analysis).

2) Unenforceability in B2C

• Consumer contracts: a clause imposing arbitration exclusively on a consumer is presumed unfair (art. R.212‑2 C. conso., Legifrance — French legislation portal) and therefore unenforceable under domestic law. This protection also derives from Directive 93/13/CEE on unfair terms.
• Standard-form contracts and clauses: if the clause was not individually negotiated with the consumer, the unfairness risk is highest (see EUR‑Lex — Directive 93/13).
• International arbitration and consumers: the state court must be able to review unfairness effectively when determining where the dispute should proceed, even with an international arbitration clause, to guarantee EU consumer protection (see EUR‑Lex — EU law portal).

When to include an arbitration clause (and when to avoid it)

Prefer it for

• Complex B2B: tech projects, software licensing, information-system integration, M&A, international distribution.
• Confidentiality: the hearing and award are not public, unlike state court proceedings.
• International matters: perceived neutrality, effective award enforcement in many States (exequatur).
• Manageable timing: procedures often faster and more flexible than court litigation.

Avoid it for

• B2C / non-professionals: unenforceable and presumed unfair (art. R.212‑2 C. conso.).
• Small amounts: arbitration costs (institution fees, arbitrators) may exceed the amount at stake.
• Urgent measures in rem: seizures, interim evidentiary measures… state courts often remain more effective. You can nevertheless provide for an “emergency arbitrator” if the chosen institution offers one.

Alternative or complement: a jurisdiction clause may be more suitable if you wish to remain before state courts.

How to draft a clause that holds up (content checklist)

• Seat of arbitration (e.g. Paris): determines procedural law and support from the supporting judge (juge d’appui).
• Institution (ICC, CMAP, etc.) or ad hoc arbitration: refer to clear rules.
• Number of arbitrators (one or three) and appointment method.
• Language and substantive governing law.
• Scope: “any dispute concerning the validity, interpretation, performance or termination of the contract”.
• Confidentiality and data protection (GDPR) for documents and transfers; follow CNIL good practice (CNIL — French data protection authority).
• Joinder/consolidation for related contracts or multiple parties.
• Amicable settlement first (mediation/conciliation) before arbitration: see our advice on mediation and conciliation.

Sample standard clause (adapt before use)

“Any dispute arising from the formation, validity, interpretation, performance and/or cessation of this contract shall be settled by arbitration under the [ICC/CMAP] Rules by [a sole arbitrator/a tribunal of three arbitrators]. The seat of arbitration shall be [City, country]. The language of the proceedings shall be [French/English]. The substantive governing law shall be the law of [country]. The proceedings and award shall be confidential.”

Common mistakes to avoid

• Pathological clause: ambiguous references (“arbitrator to be appointed by mutual agreement” without a fallback mechanism, no seat, unidentifiable institution).
• Excessive asymmetry: a clause allowing only one party to go to a state court while requiring the other to arbitrate: substantial uncertainty.
• Overly narrow scope: clauses excluding tort liability or termination; prefer wording covering “any dispute relating to or in connection with”.

Practical procedure and costs: what to expect

1. Notify the request to the institution or opposing party (ad hoc).
2. Appoint arbitrators and set the procedural timetable.
3. Exchange submissions, produce documents, hold a hearing if applicable.
4. Reasoned award; then exequatur for compulsory enforcement in France (see Book IV CPC).

Duration: frequently 6 to 18 months depending on complexity. Costs: administrative charges, arbitrator and lawyer fees; where costs are below the amount at stake, sometimes prefer state courts or mediation.

Common startup cases

• SaaS terms of sale: clearly distinguish B2B and B2C offerings. Avoid B2C arbitration and structure professional terms accordingly; see current obligations in our SaaS terms-of-sale guide.
• Services contracts: consider multiple contracts (licence + integration + maintenance). Plan consolidation of proceedings and coordination with the amicable escalation clause; see points to watch in services contracts.
• B2B SaaS contracts: check consistency between the arbitration clause and SLAs, penalties, exit arrangements and confidentiality; checklist in this B2B SaaS review guide.
• Personal data and trade secrets: organise secure evidence exchange and anonymisation if needed, in line with CNIL guidance.

Validation checklist before signing

• Is the customer acting professionally? (enforceability condition)
• Is the clause written and accepted by both parties? (art. 1443 CPC)
• Are seat, institution, number of arbitrators, language and governing law clearly defined?
• Does scope cover all disputes relating to the contract?
• Is the clause not unfair if there is a B2C risk? (art. R.212‑2 C. conso., Directive 93/13)
• Are confidentiality and GDPR addressed for documents and data? (CNIL — French data protection authority)
• Are exequatur and compulsory enforcement in France anticipated? (Book IV CPC)
