Business Mediation: Resolve Disputes Without Going to Court

Business mediation in Spain became mandatory as a prior step to civil and commercial litigation under Organic Law 1/2025, which entered into force on 3 April 2025. This law requires parties to attempt an Adequate Dispute Resolution Mechanism (MASC — Mecanismo Adecuado de Solución de Controversias) before filing a claim, and courts now reject proceedings that do not include proof of this prior attempt. Mediation itself is governed by Law 5/2012 on Civil and Commercial Mediation, which transposed EU Directive 2008/52/EC and establishes that mediation agreements signed before an accredited mediator can be elevated to enforceable instruments.

Our team combines expertise in commercial law, dispute resolution, and facilitation to run mediation processes that resolve conflicts in weeks — and produce agreements that hold.

Why Organic Law 1/2025 Closed the Courthouse Door Without a MASC Attempt

Since 3 April 2025, no company can file a civil or commercial claim in Spain without first demonstrating that it has attempted to resolve the dispute through a MASC — a Medios Adecuados de Solucion de Controversias, or appropriate dispute resolution mechanism. Organic Law 1/2025 made this a formal admissibility condition: courts reject claims that do not include the MASC attempt certificate at the moment of filing.

The practical impact is immediate. A company that receives a formal demand letter or decides to pursue a claim against a supplier, distributor, or business partner must activate the MASC process before presenting the claim to the court. Without that step, the court returns the filing unprocessed. Many companies discovered this change after their lawyers had already drafted the claim and the prescription period was running.

Mediation vs Litigation: Cost, Timeline, and the Commercial Relationship

Business mediation resolves disputes in weeks, not years. A civil or commercial first-instance court proceeding in Spain takes between two and five years depending on the court and the complexity of the matter. Structured mediation with experienced professionals resolves the same dispute in four to twelve weeks. The cost saving is equally significant: combined mediation fees for both parties are typically lower than one party’s lawyers and court representatives for a single judicial instance.

The most relevant advantage for businesses is often not economic or temporal — it is the preservation of the commercial relationship. In litigation, parties adopt adversarial positions that irreparably damage any possibility of future collaboration. In mediation, the process is designed for parties to reach an agreement that addresses their real interests, not just their legal positions. The supplier who is today’s defendant may be next year’s strategic partner.

When mediation is not possible or the counterparty refuses to participate, our litigation and arbitration team takes over with the full documented record and strategy already defined. The coordination between the mediation team and the litigation team is a distinctive advantage of working with BMC across both stages.

The MASC Certificate: What Courts Actually Require

The MASC attempt certificate must accompany the claim at the moment of filing. It must be issued by the accredited mediator or mediation institution and include: identification of the parties, nature of the dispute, dates of communications and sessions, and outcome of the process (agreement reached or failed attempt). A certificate issued by a non-accredited mediator or with insufficient content may be rejected by the court.

We issue MASC certificates that comply with all formal requirements of Organic Law 1/2025 and the criteria being applied by civil and commercial courts in the main Spanish jurisdictions. The certificate includes all documentation needed for the party’s lawyer to incorporate it directly into the statement of claim without risk of inadmissibility.

International Disputes and Cross-Border Mediation

Disputes involving counterparties from other EU Member States or third countries have their own mediation framework. We handle international mediations under ICC Rules and WIPO procedures for intellectual property conflicts. International mediation agreements are enforceable across the EU and in countries party to the Singapore Convention on Mediation — making a well-drafted international mediation agreement enforceable in more jurisdictions than many arbitral awards.

For companies operating across multiple European jurisdictions, international mediation can be more cost-effective than ICC arbitration for disputes below EUR 5 million. We advise on forum selection and coordinate with local counsel when the dispute involves foreign law. Where disputes arise from M&A transactions or joint ventures, we coordinate the mediation with our corporate advisory team to ensure that any settlement integrates correctly with the underlying transaction documentation.

Regulatory Framework: Organic Law 1/2025 and Law 5/2012

Mediation in Spain is governed by Law 5/2012 on Civil and Commercial Mediation, which transposed EU Directive 2008/52/EC and established the legal framework for mediation agreements, the accreditation of mediators, and the principle of confidentiality in mediation proceedings. Organic Law 1/2025 on efficiency measures for the Public Justice Service, which entered into force on 3 April 2025, added the mandatory MASC requirement: Article 6 now requires parties to any civil or commercial claim to demonstrate, at the time of filing, that they have attempted an adequate dispute resolution mechanism. Failure to do so renders the claim inadmissible.

The mandatory nature of the MASC requirement distinguishes Spain from other EU jurisdictions. The 2008 Directive encouraged but did not mandate mediation attempts. Organic Law 1/2025 goes further: courts in Madrid, Barcelona, Málaga, and all other Spanish jurisdictions now have an obligation to verify the MASC certificate at the point of admission. A claim filed without it is returned unprocessed and the prescription period resumes running immediately.

Sectors Particularly Affected

Technology and startups: intellectual property disputes between co-founders, licensing agreement renegotiations, and software delivery disputes are ideal candidates for mediation because the commercial relationship typically has ongoing value that litigation would destroy. The WIPO Arbitration and Mediation Center offers specialised procedures for these cases.

Hospitality and tourism: supplier payment disputes, franchise agreement conflicts, and hotel management contract terminations have a strongly recurring commercial dimension where preserving the relationship outweighs winning a legal point. Mediation in these cases also avoids the reputational exposure of public court proceedings.

Real estate: commercial lease renegotiations — particularly relevant since the 2020-2022 period of operating restrictions — shareholder disputes in real estate investment vehicles, and construction contract defects claims where the relationship between developer, contractor and subcontractor needs to be maintained.

Consumer retail: distributor-supplier price disputes, commercial promotion and exclusivity agreement terminations, and private label contract interpretations are highly suitable for mediation because the parties need each other commercially and litigation destroys the pricing and commercial framework for both sides.

Company Size Segmentation

Autónomos and microenterprises benefit most immediately from the cost advantage of mediation. A EUR 30,000 client debt claim that would cost EUR 5,000-8,000 in legal fees for first-instance litigation can be resolved through mediation in eight to twelve weeks for a fraction of that cost. The mandatory MASC requirement also means that attempting mediation is no longer optional — it is a procedural prerequisite for any collection or contract claim.

SMEs face a more complex picture: the mandatory MASC requirement now applies to virtually all commercial disputes, and companies without an internal legal function are most exposed to the risk of filing a claim without the required certificate. We design and manage the entire MASC process for these clients, from counterparty notification through to certificate issuance.

Corporate groups use mediation strategically — not merely as a compliance step but as a genuine dispute resolution tool for disputes where the value of the commercial relationship, the confidentiality of the process, or the reputational risk of public litigation makes a negotiated solution strongly preferable. We design corporate mediation protocols and model clauses for inclusion in standard commercial contracts.

Worked Example: Distributor Dispute — MASC Process and Outcome

A Madrid-based food manufacturing company (annual revenue: EUR 12 million) was in dispute with its principal distributor over alleged shortfalls in minimum purchase obligations under a three-year exclusive distribution agreement. The distributor claimed force majeure; the manufacturer claimed breach of contract and sought EUR 280,000 in damages and early termination of the exclusivity.

Under Organic Law 1/2025, filing the claim directly with the court was no longer possible without prior MASC evidence. The manufacturer’s lawyer initiated the BMC mediation process:

• Week 1: conflict assessment and interest mapping. The manufacturer’s primary interest was securing guaranteed volumes for the following two years, not the back-payment claim. The distributor’s primary interest was avoiding a public legal dispute that would damage its market reputation.
• Weeks 2-4: three structured mediation sessions. Facilitative techniques were used to move both parties from positional bargaining to interest-based negotiation.
• Week 6: agreement reached. New three-year distribution agreement with revised purchase minimums, a EUR 75,000 partial settlement, and a joint communication to market confirming the renewed partnership.
• Week 7: MASC certificate issued (agreement reached), mediation agreement elevated to notarial deed for direct enforcement weight.

Total cost of the mediation: EUR 4,200 for both parties combined. Estimated cost of first-instance litigation: EUR 35,000-50,000 per party, with a 3-5 year timeline and an uncertain outcome.

Common Mistakes in Mandatory MASC Compliance

1. Treating the MASC requirement as a formality. Some companies instruct a lawyer to issue a pro forma mediation invitation to the counterparty with no genuine intention of mediating. Courts are increasingly scrutinising the substance of MASC attempts — a letter that manifestly fails to engage with the dispute on its merits may not satisfy the requirement.

2. Failing to account for prescription periods. The mandatory MASC attempt does not suspend the prescription period automatically for all claim types. The rules governing prescription suspension during mediation depend on when formal mediation is initiated. Managing this interface correctly requires coordination between the mediation process and the underlying claim.

3. Using non-accredited mediators. The MASC certificate must be issued by an accredited mediator under Law 5/2012. A certificate from an individual who does not meet the accreditation requirements is invalid. We verify accreditation status before assigning any mediator.

4. Not including mediation clauses in commercial contracts. Many companies go through the mandatory MASC process reactively — after a dispute has arisen. A well-drafted mediation clause in the original commercial contract can specify the mediation institution, the mediator selection mechanism, the language of proceedings, and the governing law of any settlement, significantly reducing procedural friction when a dispute does arise.

5. Failing to elevate the mediation agreement to a notarial deed. A mediation agreement is binding as a contract, but without notarial elevation it lacks direct enforcement weight — meaning that if the other party defaults, a new court claim must be filed. Elevating to a notarial deed converts the agreement into a directly enforceable instrument equivalent to a court judgment.

Geographic Coverage

We conduct business mediations in Madrid, Barcelona, Málaga, Marbella, and Las Palmas de Gran Canaria. For international disputes involving EU counterparties, we coordinate proceedings through ICC and WIPO institutional frameworks with sessions by video conference or at the relevant institutional venues. Our mediators are accredited under the registers maintained by the Spanish Ministry of Justice and the relevant bar associations.

Mediation services are coordinated with our litigation and arbitration practice to ensure seamless transition between the mandatory MASC process and court or arbitral proceedings when settlement is not achieved.

Five Questions to Ask Before Filing a Civil or Commercial Claim

Before instructing a lawyer to draft a claim, every company should confirm:

1. Has the MASC attempt been completed or formally initiated — and is there a certificate that meets the formal requirements of Organic Law 1/2025 to accompany the filing?
2. Is the prescription period still running, and has the interaction between the mediation start date and any statutory suspension clock been verified?
3. Does the dispute involve a counterparty whose commercial relationship has ongoing value — and has the cost of destroying that relationship been weighed against the cost of a negotiated settlement?
4. Does your standard commercial contract include a mediation clause that specifies the institution, language, and governing law of any settlement — or will the parties be arguing about procedure before even discussing substance?
5. Has the counterparty’s refusal to mediate been documented in a way that can be presented to the court as evidence of their obstructive conduct for the purposes of costs?

Prescription Periods and the MASC Obligation: The Intersection That Catches Companies Out

The mandatory MASC requirement introduced by Organic Law 1/2025 does not automatically suspend the prescription period for all civil and commercial claims. The interaction between the start of a mediation process and the running of prescription depends on the type of claim and when formal mediation is initiated. For contractual claims under the Civil Code, the prescription period is five years (reduced from fifteen years in 2015); for claims arising from tortious conduct, one year; for commercial claims under the Commercial Code, shorter specific periods apply.

The practical risk is this: a company that discovers a breach of contract in month one and decides to attempt mediation before filing has potentially lost prescription protection for any prescription period that ran during the mediation, depending on whether the formal mediation start date falls within the statutory suspension window. Companies that use the MASC process as a genuine dispute resolution tool — rather than a pro forma box-tick — need the clock management to be handled by specialists who understand the interface between the procedural obligation and the substantive limitation rules.

The Internal Mediation Protocol: From Reactive to Strategic

Most companies treat the mandatory MASC requirement reactively: a dispute arises, they call their lawyer, the lawyer initiates the mediation process. The strategic approach is different. A well-designed internal mediation protocol means that:

The standard commercial contracts already include a mediation clause specifying the institution (ICC, ICAM, CICAC), the mediator selection mechanism, the language of proceedings, and the governing law of any settlement agreement. This reduces procedural friction dramatically — the parties do not need to agree on how to mediate before they can start mediating.

The company has appointed a designated internal MASC officer responsible for activating the protocol when a dispute reaches a defined escalation threshold. This creates institutional memory and reduces the risk of a claim being filed without the required certificate.

The legal team has been trained on the criteria courts are applying to assess whether a MASC attempt was genuine — a training session that prevents the pro-forma mediation letter that courts are beginning to reject as insufficient.

We design these protocols for corporate groups and large companies as part of a broader commercial conflict management system that connects to the company’s standard contract templates, its litigation risk register, and its insurance coverage for commercial disputes.

BMC Ecosystem: Connecting Mediation to the Full Legal Lifecycle

Business disputes do not arise in isolation. A distribution agreement dispute may involve underlying questions about the intellectual property rights licensed under the agreement. A shareholder conflict mediation may need to incorporate a share buyout structured with tax efficiency. A construction dispute settlement may require integration with an ongoing real estate transaction that involves the same parties.

We coordinate the mediation process with our corporate advisory, tax, and litigation teams to ensure that settlements are legally sound in all dimensions — not just in terms of resolving the dispute, but in terms of the transactional, tax, and regulatory implications of the agreement. This integrated approach is particularly relevant in post-M&A disputes, joint venture conflicts, and any situation where the settlement terms need to work within an existing corporate or contractual framework.

Our criminal compliance team can advise in parallel where a commercial dispute has potential criminal dimensions — for example, supplier fraud cases or contract bid manipulation — helping the company manage the criminal exposure separately from the commercial mediation process.
