Mediation Clause

TL;DR: A mediation clause requires the contracting parties to attempt non-binding mediation before commencing arbitration or litigation. Drafted as a stand-alone provision or as one tier of a stepped (multi-tier) dispute resolution mechanism, it typically specifies the trigger, the time window for selecting a mediator, the institutional rules (JAMS, AAA, ICC, CEDR, or ad hoc), the seat, the language, the cost allocation, and the time-bar for moving to the next step. Enforceability turns on whether the clause is drafted as a condition precedent to suit (HIM Portland v. DeVito Builders, 1st Cir. 2003) or merely as a covenant the breach of which sounds in damages, so the drafting choices control whether a court will stay or dismiss a premature filing.

‍

What Is a Mediation Clause?

A mediation clause is a contractual provision under which the parties agree, in advance of any dispute, to submit specified controversies to a neutral third party for facilitated, non-binding settlement discussions. The mediator does not issue a decision; the mediator helps the parties identify interests, surface settlement options, and reach a consensual resolution. If mediation fails, the dispute proceeds to the next step (arbitration or litigation), and the mediator's communications are confidential and inadmissible in any subsequent proceeding.

Mediation clauses appear in two principal forms. The first is a stand-alone mediation requirement, in which the parties commit only to mediate before suit. The second, and more common in commercial practice, is a multi-tier or stepped dispute resolution clause that sequences negotiation, mediation, and a binding step (arbitration or litigation) as successive conditions. The classic three-tier structure requires senior-executive negotiation within a fixed window (often 15-30 days), then mediation under named institutional rules within a further window (often 30-60 days), and only then permits a party to file an arbitration demand or court complaint.

The legal effect of a mediation clause depends on how the obligation is framed. A clause drafted as a condition precedent ("no party shall commence litigation or arbitration until mediation has been completed or terminated") is generally enforced by U.S. courts through dismissal or stay of a premature suit. A clause drafted as a covenant or aspirational commitment ("the parties shall first attempt to resolve any dispute through mediation") may be treated as a procedural obligation whose breach gives rise only to damages, with the underlying suit allowed to proceed. Practitioners distinguish the two by looking for mandatory language, a clear sequencing requirement, and institutional rules that make completion verifiable.

Mediation clauses are standard in construction contracts (AIA A201 General Conditions treat mediation as a condition precedent), commercial leases, joint venture and shareholder agreements, technology and licensing deals, and cross-border supply and distribution agreements. International contracts increasingly couple mediation with ICC International Centre for ADR, SIMC, or CEDR rules, often with a Singapore Convention enforcement reference.

Why It Matters

• Cost and speed advantage over litigation: JAMS reports that the typical commercial mediation runs one day, with mediator fees of $5,000 to $15,000 per side for a single session, against hundreds of thousands in litigation costs and 18-30 months to trial in most U.S. federal districts (JAMS Commercial Mediation Statistics, 2024).
• High settlement rates when parties show up: Institutional providers report settlement rates of 70-85% for commercial mediations that reach a session. CEDR's 2023 Mediation Audit reported an aggregate settlement rate of 89% (72% on the day of mediation and a further 17% shortly after).
• Preserves the commercial relationship: Mediation is non-binding and confidential, allowing ongoing business counterparties (joint venture partners, long-term suppliers, franchisees, lessors and lessees) to settle without on-the-record positions that poison the relationship.
• Confidentiality and without-prejudice protection: Statements in mediation are protected by mediation privilege (U.S.: Uniform Mediation Act in adopting states; U.K.: without-prejudice rule and contractual confidentiality; international: Article 9 of the UNCITRAL Model Law on International Commercial Mediation, 2018).
• Enforceability of cross-border settlements: The Singapore Convention on Mediation (in force September 12, 2020) provides treaty-based direct enforcement of mediated settlement agreements in signatory states, parallel to the New York Convention for arbitral awards. As of 2025 it has 57 signatories and 14 ratifying states.
• Filters weak claims and narrows live ones: Even when mediation fails, the process forces both sides to organize facts, retain experts, and articulate damages theories. Downstream arbitration or litigation is shorter and cheaper as a result.

Key Elements of a Well-Drafted Mediation Clause

1. Mandatory language and condition-precedent framing: Use "shall" not "may," and state expressly that no party may commence arbitration or file suit (other than for provisional relief) until mediation has been completed or terminated. The First Circuit in HIM Portland, LLC v. DeVito Builders, Inc., 317 F.3d 41 (1st Cir. 2003) enforced an AIA mediation provision precisely because the language treated mediation as a condition precedent.
2. Scope of disputes: Define the disputes covered. "Any dispute, claim, or controversy arising out of or relating to this Agreement, or the breach, termination, validity, or interpretation thereof" is the broad formulation; carving out IP infringement, requests for provisional or injunctive relief, and collection actions for undisputed amounts is standard.
3. Trigger and notice: Specify what initiates the obligation - typically a written "Notice of Dispute" delivered under the contract's notice provision. State the contents required (description of the dispute, requested relief, and proposed mediator) and deem the mediation period to start on receipt.
4. Selection of mediator and institutional rules: Identify the rules (e.g., JAMS International Mediation Rules, AAA Commercial Mediation Procedures, ICC Mediation Rules 2014, CEDR Model Mediation Procedure). State how the mediator is selected (party agreement within X days; failing agreement, appointment by the institution from a panel of commercial neutrals with specified experience in the relevant industry).
5. Seat, venue, and language: Designate the physical or virtual seat of the mediation, the governing law of the mediation agreement, and the language of proceedings. For cross-border deals, naming a neutral seat (Singapore, London, New York) avoids one party's home-court advantage and aligns with the chosen institutional rules.
6. Time limits and termination right: Set a hard time-bar (typically 60 or 90 days from the Notice of Dispute) after which either party may unilaterally declare the mediation terminated and proceed to arbitration or litigation. Without a time-bar, a recalcitrant party can stall indefinitely by refusing to schedule sessions.
7. Cost allocation: Specify that each party bears its own attorneys' fees and that mediator fees and institutional administrative charges are shared equally, unless the parties agree otherwise in the mediation submission. Carve out the right of the prevailing party in any subsequent proceeding to recover mediation costs if the contract has a fee-shifting provision.
8. Confidentiality and inadmissibility: Provide that all communications in mediation are confidential, without prejudice, and inadmissible in any subsequent arbitration or litigation, except for documents that would be discoverable independently. Reference the applicable mediation privilege statute (e.g., Uniform Mediation Act in the seat jurisdiction) for belt-and-suspenders protection.
9. Tolling of limitation periods: Expressly toll all contractual and statutory limitation periods from the date of the Notice of Dispute through the date the mediation is terminated. Without tolling language, a party may be forced to file a protective suit to preserve a limitations defense even while mediation is ongoing.
10. Carve-out for provisional relief: Permit either party to seek temporary restraining orders, preliminary injunctions, attachments, or other provisional remedies in any court of competent jurisdiction without breaching the mediation clause. Without this carve-out, a party facing irreparable harm cannot protect itself during the mediation window.

Market Position & Benchmarks

Where Does Your Clause Fall?

• Plaintiff-Favorable (Light-Touch): Permissive language ("the parties may attempt mediation"), no fixed time-bar before suit, no condition-precedent framing, optional institutional rules, and a broad carve-out allowing either party to file suit at any time "if mediation appears unlikely to succeed." In effect, the clause is aspirational and a court will not enforce it as a bar to suit.
• Market Standard (Stepped): Mandatory three-tier dispute resolution - good-faith negotiation between named senior executives within 30 days of a Notice of Dispute, followed by mediation under JAMS or AAA Commercial Mediation Rules within 60 days, followed by binding arbitration or litigation in the designated forum. Express condition-precedent language, tolling of limitations, confidentiality, and a carve-out for provisional relief and IP infringement claims.
• Defendant-Favorable (Strict Gate): Hard condition precedent with no carve-outs, mandatory in-person mediation in the defendant's home jurisdiction, requirement that the mediation use a specific named mediator or panel, dismissal (not stay) of any premature suit, and a fee-shifting provision making the party that bypassed mediation liable for the other side's costs. Often paired with a long limitations period to make the strict gate workable.

Market Data

• JAMS reports that approximately 80% of commercial mediations conducted under its Commercial Mediation Procedures result in a binding settlement, with the average single-issue commercial mediation lasting one day and complex multi-party matters running two to three days (JAMS 2024 Annual Report).

• CEDR's 2023 Mediation Audit (the U.K. industry benchmark, eleventh edition) reported an aggregate settlement rate of 89%, an estimated commercial value of disputes mediated annually in the U.K. of GBP 17.5 billion, and median mediator fees of GBP 4,000-7,500 per party per day for non-CEDR-administered cases.
• The ICC International Centre for ADR administered 36 new mediation requests in 2023 under the ICC Mediation Rules, with parties from 41 jurisdictions; the ICC reports an overall settlement rate above 75% for cases that proceed to mediation (ICC Dispute Resolution Statistics, 2024).
• The Singapore International Mediation Centre (SIMC) reported a settlement rate of 70% in 2023 with an average case duration of 1.5 days and average claim values exceeding USD 30 million for cross-border commercial disputes.
• Approximately 65% of U.S. construction contracts incorporating AIA A201 (2017 edition) preserve the standard mediation-as-condition-precedent provision, making construction one of the most consistent users of stepped dispute resolution (American Arbitration Association Construction Industry Survey, 2023).
• The Singapore Convention on Mediation entered into force September 12, 2020, and as of late 2025 has 57 signatories and 14 states for which the Convention is in force, including Singapore, Belarus, Ecuador, Fiji, Honduras, Qatar, Saudi Arabia, Turkey, and Kazakhstan; the U.S., U.K., EU member states, and most major economies have signed but not ratified.

Sample Language by Position

Light-Touch (Permissive): "The parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement through informal discussions and, if useful, voluntary mediation. Nothing in this Section shall preclude either party from commencing litigation or arbitration at any time."

Market Standard (Stepped, Mandatory): "Any dispute arising out of or relating to this Agreement shall be submitted first to non-binding mediation administered by JAMS in accordance with its Commercial Mediation Procedures. The mediation shall be a condition precedent to the commencement of any arbitration or litigation. The party initiating the dispute shall deliver a written Notice of Dispute to the other party, and the parties shall jointly select a mediator within fifteen (15) days. If no mediator is selected within that period, JAMS shall appoint one. The mediation shall be held in [City] within sixty (60) days of the Notice of Dispute. If the dispute is not resolved within ninety (90) days of the Notice of Dispute, either party may terminate the mediation and proceed to [arbitration/litigation] under Section [X]. All applicable limitation periods shall be tolled from the date of the Notice of Dispute through the termination of the mediation. Notwithstanding the foregoing, either party may seek provisional or injunctive relief in any court of competent jurisdiction without first mediating."

Strict Gate (Defendant-Favorable): "As a strict condition precedent to the filing of any arbitration demand, court complaint, or other proceeding, the parties shall complete mediation under the ICC Mediation Rules in [Seat], with a single mediator appointed by the ICC International Centre for ADR. The party initiating the dispute shall pay the ICC filing fee and shall not commence any other proceeding until the mediator has issued a certificate of termination. Any complaint or arbitration demand filed in violation of this Section shall be dismissed with prejudice on motion, and the filing party shall pay the other party's reasonable attorneys' fees and costs incurred in obtaining the dismissal."

Example Clause Language

The following examples illustrate mediation provisions tailored to specific transaction types and risk profiles.

Construction Contract (AIA-Style, Condition Precedent): "Claims, disputes, or other matters in controversy arising out of or related to this Agreement shall be subject to mediation as a condition precedent to binding dispute resolution. The parties shall endeavor to resolve their Claims by mediation administered by the American Arbitration Association in accordance with its Construction Industry Mediation Procedures in effect on the date of this Agreement. A request for mediation shall be made in writing, delivered to the other party, and filed with the AAA. The request may be made concurrently with the filing of binding dispute resolution proceedings but, in such event, mediation shall proceed in advance of binding dispute resolution proceedings, which shall be stayed pending mediation for a period of 60 days from the date of filing, unless stayed for a longer period by agreement of the parties or court order."

International Joint Venture Agreement (Singapore Seat, ICC Rules): "Any dispute arising out of or in connection with this Agreement, including any question regarding its existence, validity, or termination, shall first be referred to mediation under the ICC Mediation Rules. The seat of the mediation shall be Singapore and the language shall be English. The mediator shall be a senior commercial practitioner with at least 15 years of experience in international joint ventures, appointed by the ICC International Centre for ADR if the parties do not agree within 21 days of the request for mediation. If the dispute is not settled within 90 days of the filing of the Request for Mediation, or such longer period as the parties may agree in writing, either party may commence arbitration under Section [X]. The parties acknowledge and agree that any settlement agreement reached in the mediation may be enforceable under the United Nations Convention on International Settlement Agreements Resulting from Mediation (the Singapore Convention)."

SaaS Master Agreement (Stepped, Carve-Out for IP and Fees): "Before initiating any arbitration or litigation under Section [X], the parties shall attempt to resolve any dispute through the following process: (a) the disputing party shall send a written Notice of Dispute to the other party's General Counsel; (b) within 20 business days, designated senior executives of each party shall meet in person or by videoconference to negotiate in good faith; (c) if the dispute remains unresolved 30 days after the Notice of Dispute, either party may submit the matter to mediation under the JAMS Streamlined Mediation Rules, with a single mediator selected by the parties or, failing agreement within 10 business days, appointed by JAMS. Notwithstanding the foregoing, either party may at any time (i) seek injunctive or other equitable relief to prevent or stop infringement or misappropriation of its intellectual property or breach of confidentiality obligations, or (ii) commence collection proceedings for undisputed amounts due. All limitation periods shall be tolled from the Notice of Dispute through 30 days after the mediator declares the mediation terminated."

Common Contract Types

• Construction and engineering contracts: AIA A201 (2017), ConsensusDocs, FIDIC Red and Yellow Books, and most U.S. state public works forms include mediation as a condition precedent, fitting an industry where project relationships, technical complexity, and the cost of stopping work favor early settlement.
• Commercial leases and real estate purchase agreements: Standard in CAR (California Association of Realtors) and many local bar association forms. Disputes over operating expenses, build-out costs, exclusivity, and percentage rent suit mediated resolution because the landlord-tenant relationship typically continues beyond the dispute.
• Joint venture, shareholder, and partnership agreements: Mediation preserves the operating relationship and avoids public disclosure. Cross-border JVs typically use ICC, SIMC, or CEDR rules with a neutral seat and a Singapore Convention reference.
• Franchise agreements: Many U.S. state franchise statutes encourage or require pre-suit mediation, and the FTC Franchise Rule disclosure (Item 17) commonly recites the mechanism. Franchisee-protective state laws may override and require mediation in the franchisee's state.
• Licensing, technology transfer, and SaaS agreements: Mediation preserves confidentiality of commercial terms and trade secrets, while the carve-out for injunctive relief on IP infringement protects the licensor's ability to act against unauthorized use.
• Distribution, supply, and OEM agreements: Long-term supply relationships benefit from mediated resolution of pricing disputes, quality claims, and territorial issues, often paired with arbitration under ICC, SIAC, or HKIAC rules.
• Employment separation and severance agreements: Common as a pre-suit step for executive disputes, though enforceability against employees may be limited by state statutes (e.g., California Labor Code Section 925) and federal anti-waiver provisions for certain claims.
• Family business and trust disputes: Standard in trust instruments and shareholder agreements among family members to preserve relationships and confidentiality.

Negotiation Playbook

Key Drafting Notes

• Make condition-precedent intent explicit: Courts read mediation clauses literally. Both the Fifth Circuit in Fluor Enterprises, Inc. v. Solutia Inc., 147 F. App'x 480 (5th Cir. 2005), and the First Circuit in HIM Portland (2003) turned on whether the language treated mediation as a strict prerequisite. Use "as a strict condition precedent" and "no party may file or commence" to remove ambiguity.
• Specify institutional rules and seat: Naming JAMS, AAA, ICC, CEDR, or SIMC rules imports a complete procedural framework (mediator selection, fees, confidentiality, termination certificate) that fills gaps in the contract. Ad hoc mediation works only if the parties have a strong cooperative track record; otherwise institutional rules avoid procedural disputes.
• Set hard deadlines with auto-termination: The 60- or 90-day deadline must be self-executing. Language like "the mediation shall be deemed terminated 90 days after the Notice of Dispute unless the parties agree in writing to extend" prevents one party from running out the clock by refusing to schedule.
• Toll limitations expressly: Without a tolling clause, a party with a near-expiration claim must file a protective suit to preserve the limitations defense, which defeats the point of pre-suit mediation. The tolling should run from the Notice of Dispute through 30 days after termination of the mediation.
• Coordinate with the binding step: If arbitration is the next tier, the mediation clause and arbitration clause must use compatible institutional administration (e.g., both AAA, both ICC) to avoid jurisdictional fights about whether mediation occurred. Some institutional rules permit conversion of a failed mediation to arbitration with the same neutral or institution.
• Carve out provisional relief and IP claims: A mediation requirement that prevents emergency injunctive relief is unenforceable in practice and harmful in fact. The carve-out should cover TROs, preliminary injunctions, attachments, and IP infringement actions. Some clauses also carve out collection of undisputed amounts.

Common Pitfalls

• Aspirational language treated as unenforceable: Phrases like "the parties shall endeavor to mediate" or "the parties may consider mediation" have repeatedly been held insufficient to bar suit. In Fluor Enterprises v. Solutia, the Fifth Circuit declined to dismiss because the clause did not clearly condition suit on completed mediation. Use mandatory "shall" plus express condition-precedent framing.
• No mechanism to break a mediator-selection deadlock: If the parties cannot agree on a mediator and the clause has no fallback (e.g., institutional appointment), the obligation is illusory. Always provide that the named institution will appoint if the parties fail to agree within a fixed period.
• Open-ended time period: Without a hard time-bar, a defendant can delay indefinitely by stalling on scheduling, mediator selection, or pre-mediation briefing. The 60- or 90-day cap with auto-termination is a hard requirement of any enforceable clause.
• Ignoring the limitations clock: A mediation requirement that does not toll limitations forces the claimant to file suit to preserve the claim, which may itself breach the mediation clause. The tolling provision is short, simple, and frequently omitted.
• Conflict with a separate arbitration provision: If the contract has both a mediation clause administered by JAMS and an arbitration clause administered by ICC (or vice versa), parties fight over which institution decides whether mediation occurred. Use the same administering body or expressly state that the arbitral tribunal decides compliance with the mediation step.
• Failure to address confidentiality of mediator communications: The default mediation privilege varies by jurisdiction. Without contractual confidentiality and inadmissibility language, statements in mediation may be discoverable in subsequent litigation, particularly in jurisdictions that have not adopted the Uniform Mediation Act. The clause should expressly extend without-prejudice protection.
• Overlooking cross-border enforcement of settlements: A settlement reached in mediation is, in most jurisdictions, just a contract - it must be sued upon if breached. The Singapore Convention provides direct enforcement, but only in ratifying states and only if the agreement satisfies Article 4 formalities (signature, mediator certification). Cross-border deals should reference the Convention and require the formalities at the time of settlement.

‍

Jurisdiction Notes

• U.S.: Federal courts and most state courts enforce mediation-as-condition-precedent clauses by stay or dismissal of premature suits. The leading authority is HIM Portland, LLC v. DeVito Builders, Inc., 317 F.3d 41 (1st Cir. 2003), which dismissed a contractor's suit for failing to mediate first under the AIA standard form. The Eleventh Circuit reached a similar result in Kemiron Atlantic, Inc. v. Aguakem International, Inc., 290 F.3d 1287 (11th Cir. 2002), and the Federal Arbitration Act (9 U.S.C. Sections 1-16) supplies the stay mechanism when the contract also includes arbitration. Twelve states and D.C. have adopted the Uniform Mediation Act (2001, amended 2003), which codifies the mediation privilege; California Evidence Code Sections 1115-1128 establish a strong mediation privilege; Florida Statutes Chapter 44 governs court-connected mediation.
• U.K.: English courts enforce mediation clauses where the obligation is sufficiently certain. Cable & Wireless plc v. IBM United Kingdom Ltd. [2002] EWHC 2059 (Comm) enforced a CEDR-administered mediation clause as a stay on litigation, holding that an obligation to mediate under defined institutional rules is enforceable. The Civil Procedure Rules impose a costs-sanction regime against parties that unreasonably refuse mediation (Halsey v. Milton Keynes General NHS Trust [2004] EWCA Civ 576), now substantially modified by Churchill v. Merthyr Tydfil CBC [2023] EWCA Civ 1416, which held that courts may compel parties to engage in non-court-based dispute resolution.
• Other: The UNCITRAL Model Law on International Commercial Mediation and International Settlement Agreements Resulting from Mediation (2018) provides a template for national legislation. The Singapore Convention on Mediation (in force September 12, 2020) creates a treaty regime under which signatory states enforce international mediated settlements directly, similar to the New York Convention for arbitral awards. EU Directive 2008/52/EC requires member states to ensure mediated settlements are enforceable and that limitation periods do not bar later suit. Singapore (Mediation Act 2017), Hong Kong (Mediation Ordinance Cap. 620), and Australia (Civil Dispute Resolution Act 2011, Cth) provide statutory frameworks supporting contractual mediation clauses.

‍

Related Clauses

• Dispute Resolution - The umbrella framework for negotiation, mediation, arbitration, and litigation; mediation is one tier of any stepped dispute resolution provision.
• Arbitration - The binding adjudicative step that typically follows a failed mediation in a stepped clause; institutional choice and seat should be aligned with the mediation step.
• Escalation Clause - The senior-executive negotiation tier that often precedes mediation in a three-tier dispute resolution provision.
• Forum Selection Clause - Designates the court that will hear the dispute if mediation fails and litigation (rather than arbitration) is the next step.
• Governing Law - Determines the substantive law applied to the contract and to any settlement reached in mediation; should align with the seat and institutional rules chosen.
• Jurisdiction - Establishes which courts may hear the dispute; the mediation clause carve-out for provisional relief usually points to courts of competent jurisdiction.
• Attorneys' Fees Clause - Affects cost allocation in both the mediation and any subsequent proceeding; coordinate the fee-shifting trigger with the mediation cost-allocation rules.
