Dispute Resolution & Mediation Lawyers in Lyon Plexus Avocats Law Firm
A commercial dispute, tensions between business partners, or a breakdown in a partnership all have one thing in common: they drain the energy of business leaders, undermine otherwise solid organizations, and too often end up in court when other options were available.
Elsa Lourdeau, a lawyer admitted to the Paris Bar and subsequently to the Lyon Bar since 2011, and trained in mediation at The Center for International Mediators and Arbitrators (CIMA) in 2022, advises business leaders and organizations on resolving their disputes, prioritizing amicable resolution and pursuing litigation where necessary.
Resolving a Dispute: First, Understanding What Is Really at Stake
A dispute is rarely what it appears to be on the surface. What appears to be a contractual disagreement often masks a breach of trust between partners; what looks like a governance dispute sometimes reflects an unresolved strategic disagreement. Going straight to court without first exploring amicable resolution methods can lock the dispute into a procedural framework that resolves the matter according to the law, but does not always address the underlying causes of the disagreement.
Plexus Avocats’ approach starts from this premise: a lawyer who understands human and organizational dynamics as well as the law can achieve better outcomes for their clients. Mediation and alternative dispute resolution methods are not second-tier options. They are strategic tools that preserve relationships, reduce costs, and shorten timeframes. They are the first instinct, not the last resort.
Commercial Mediation: A Structured Process for Lasting Agreements
What Commercial Mediation Can Achieve
Commercial mediation is a voluntary, confidential, and structured process in which a neutral third party—the mediator—assists the parties in developing their own solution to the dispute. Unlike a judge, the mediator does not make a ruling: they facilitate dialogue, help the parties reframe the issues, and create the conditions for an agreement that both parties fully accept.
Result: stronger, more durable agreements that are more likely to be upheld, reached within weeks rather than years of litigation. For committed companies and SSE organizations, this tool is particularly valuable: relationships between partners or between cooperative members go beyond purely financial considerations, and preserving those relationships has real value.
Mediation can be used in a wide range of situations: disputes between business partners, shareholder disputes, contract terminations, disputes with suppliers, governance tensions within an organization, and strategic disagreements between business leaders.
The New Legal Framework: The Decree of July 18, 2025
The Decree of July 18, 2025 reinforced the place of amicable dispute resolution methods within the French judicial system. For an increasing number of civil and commercial disputes, parties are now required to attempt an amicable resolution before bringing a claim before the court.
A judge may therefore refer the parties to mediation or conciliation during the proceedings, and the failure to pursue an amicable resolution beforehand may be held against the claimant. This development changes the landscape for business leaders: anticipating amicable dispute resolution, incorporating dedicated clauses into contracts, and turning to these methods as soon as a dispute arises has become a legal strategy rather than merely an option.

Disputes Specific to SSE Organizations and Committed Companies
Organizations with participatory governance (CSCIs, WCs, associations, and cooperatives) are collective decision-making environments. This strength can also give rise to specific tensions: disagreements between cooperative members over strategy, conflicts between members of an association’s executive board, disputes over the allocation of surpluses, and challenges to decisions made by the general meeting. These disputes have an institutional dimension that few lawyers genuinely understand.
Plexus Avocats advises clients in these situations with dual expertise: a thorough understanding of the legal framework governing SSE organizations (articles of association, democratic governance, majority requirements) and the ability to support amicable dispute resolution while preserving the collective. Dissolving a WC over a dispute between cooperative members that could have been resolved through mediation would be an avoidable collective failure.
Likewise, for committed companies and purpose corporation, disputes between shareholders often concern the company’s mission and values as much as their economic rights—issues that traditional court proceedings are often ill-equipped to address.
Litigation Representation: When Amicable Resolution Is Not Enough
Amicable dispute resolution methods do not resolve every dispute. Some disputes need to be brought before the commercial court or the civil court: an unfulfilled contractual obligation, serious harm, bad faith on the part of the opposing party, or an inability to reach an agreement. In such cases, Plexus Avocats represents clients and defends their interests with the same level of rigor.
The in-depth knowledge of the case developed during the amicable phase is a tangible advantage in litigation: the key issues have already been documented, the strategy anticipated, and proceedings can often be streamlined.

Frequently Asked Questions
What is commercial mediation, and how is it different from a litigation?
Commercial mediation is a voluntary and confidential process in which a neutral mediator helps the parties reach an agreement themselves. Unlike litigation, there is no judgment imposed on the parties: instead, they reach a negotiated agreement that both accept, often more quickly (within a few weeks to a few months) and at a lower cost than court proceedings.
The mediator does not decide anything, they facilitate dialogue. Elsa Lourdeau, trained in mediation at CIMA (2022), supports clients through this process in Lyon.
Has commercial mediation been mandatory since the Decree of July 2025?
The Decree of July 18, 2025 reinforced the requirement to attempt amicable dispute resolution before bringing an expanded range of civil and commercial disputes before the courts. In some cases, failing to pursue an amicable resolution may be viewed unfavorably. This framework does not make mediation systematically mandatory, but it makes it an essential step in a well-managed legal strategy.
Plexus Avocats advises its clients on the requirements applicable to their specific circumstances.
When should mediation be preferred to litigation?
Mediation is appropriate when the parties have an interest in preserving their relationship (business partners, shareholders), when a swift resolution is needed, when the dispute involves relational or strategic issues that a court cannot resolve, and when confidentiality is important.
Litigation is necessary when the opposing party is acting in bad faith, when the harm requires a court-ordered award of damages, or when urgent interim measures are required.
Elsa Lourdeau assesses this question during the initial consultation.
Can Elsa Lourdeau handle disputes between shareholders within an SSE organization?
Yes. Conflicts within SSE organizations, between members of a CSCIs or WCs, between members of an association’s executive board, or between foundation directors, are situations that Plexus Avocats understands in depth. Elsa Lourdeau also handles litigation initiated by supervisory authorities (the Préfecture) against SSE organizations facing serious dysfunctions, including associations, endowment funds, foundations, and other entities. Arbitration proceedings before the authorities of the cooperative movement (CGSCOP) can also be handled by Plexus Avocats. Combining in-depth knowledge of the specific legal framework governing these organizations with mediation expertise makes it possible to intervene effectively before a dispute jeopardizes the organization itself. This is a rare positioning in Lyon.
How to include a mediation clause in a commercial contract?
A mediation clause contractually requires the parties to attempt an amicable resolution before initiating legal proceedings in the event of a dispute. It should specify the procedure for initiating the mediation, the choice of mediator (or mediation center), the timeframe, and how the costs will be allocated. When drafted accurately, it is legally binding and provides an effective protective mechanism for both parties.
Elsa Lourdeau incorporates these clauses into commercial contracts and shareholders’ agreements.
What are the costs of commercial mediation compared with litigation?
Commercial mediation generally lasts from a few weeks to three months, with the costs shared between the parties and covering the mediator’s fees as well as those of their respective lawyers.
Commercial litigation can take one to three years at first instance, with significantly higher costs for court proceedings, expert assessments, and legal fees, not to mention the indirect costs for management and teams.
Elsa Lourdeau provides a realistic cost estimate from the initial consultation.
Does Plexus Avocats represent clients before the Lyon Commercial Court?
Yes. When amicable resolution does not succeed or is not appropriate, Plexus Avocats represents and defends its clients before the Commercial Court or the Civil Court. The knowledge of the case gained during the amicable phase provides a tangible advantage in conducting litigation.
