France's gateway to the Mediterranean — where Europe's busiest port, the Euroméditerranée business district, and 2,600 years of commercial heritage converge.
Marseille is where Europe meets North Africa and the Mediterranean — and where GSDA's maritime, construction, and cross-Mediterranean practice is anchored. The Marseille-Fos Port handles 100 million tons of cargo annually. CMA CGM, the world's third-largest shipping line, is headquartered here. The Euroméditerranée urban renewal — one of southern Europe's largest — has attracted over €7 billion in investment. For clients in shipping, energy, port infrastructure, or any business that crosses the Mediterranean, our Marseille avocats deliver the local depth and international reach the market requires.
What makes our Marseille presence distinctive is the combination of strong regional court practice and direct connectivity to North Africa and the Gulf. Marseille has deep commercial and cultural ties to Algeria, Tunisia, and Morocco — ties that most Paris-based firms treat as footnotes but that we leverage daily through our avocats' experience and our offices in Dubai, Riyadh, and Cairo. When a Franco-Algerian joint venture needs counsel who understands both the Tribunal de Commerce de Marseille and the commercial dynamics of the Maghreb, we are the firm that delivers.
Office Details
Industries we serve
Marseille-Fos is France's premier port — handling 100 million tons of cargo annually, including 60% petroleum products — and the headquarters of CMA CGM.

Marseille welcomes 4.1 million visitors annually and is a major Mediterranean cruise port with 890,000 cruise passengers per year. The European Capital of Culture 2013 legacy, the MuCEM, Calanques National Park, and the city's gastronomy drive significant hotel, hospitality, and real estate investment requiring corporate, regulatory, and transactional legal support.
We represent shipowners, charterers, cargo interests, and insurers in maritime disputes before the Tribunal de Commerce de Marseille — France's busiest maritime jurisdiction — and in arbitration. Our work covers charterparty claims, cargo damage, demurrage, and ship arrest applications.
We advise French and North African clients on cross-border acquisitions, joint ventures, and corporate restructurings bridging Europe and the Maghreb — navigating French foreign investment screening, Algerian and Tunisian investment regulations, and the cultural dynamics that determine deal success.
Marseille's construction pipeline — Euroméditerranée, port infrastructure, coastal developments — generates significant legal work. We advise on procurement contracts, CCAG compliance, delay and defect claims, and décennale guarantee disputes for developers, contractors, and public entities.
We handle acquisitions, dispositions, and financings of commercial real estate across the PACA region — office, retail, logistics, and hotel properties — including due diligence, SPA negotiation, lease structuring, and regulatory approvals for development projects.
Marseille's port, tourism, and technology employers manage diverse, multilingual workforces. We advise on French employment contracts, collective agreements, restructurings, and the specific challenges of managing employees across Franco-Mediterranean operations.

Regulatory environment
Marseille operates within the French civil-law system under the same foundational codes — Code Civil, Code de Commerce, Code du Travail — as Paris and our other French offices. The Barreau de Marseille (Ordre des avocats du Barreau de Marseille) is one of the largest bars in France outside Paris, with a tradition of strong advocacy in commercial, maritime, and construction matters. GSDA's Marseille-based avocats are members of the Barreau and hold full rights of audience before the local courts.
The Cour d'appel d'Aix-en-Provence — one of France's busiest appellate courts, covering the Bouches-du-Rhône, Var, Alpes-de-Haute-Provence, and Hautes-Alpes departments — hears appeals from the Tribunal de Commerce de Marseille, the Tribunal Judiciaire de Marseille, and the Conseil de Prud'hommes. Marseille's status as a major port city means the Tribunal de Commerce handles a significant volume of maritime and international trade disputes, while the city's construction boom drives a steady caseload of VEFA, décennale, and procurement claims.
Key regulatory bodies impacting practice in the PACA region include the Direction Régionale de l'Économie (DREETS) for employment and competition matters, the regional office of the DREAL for environmental and energy project approvals, and the Préfecture Maritime de la Méditerranée for maritime regulatory issues. The Euroméditerranée Établissement Public d'Aménagement manages the public-private urban development that has reshaped the city's commercial landscape. For clients with international operations, Marseille's proximity to the Cour d'appel d'Aix-en-Provence and its TGV link to Paris (3 hours) ensure efficient access to the ICC International Court of Arbitration and national regulatory bodies when matters escalate beyond the regional jurisdiction.
The GSDA advantage
Strategic presence in France's premier maritime and Mediterranean trade hub — essential for clients in shipping, energy, port infrastructure, and Euro-Mediterranean commerce.
Deep local knowledge of the Marseille-Fos port economy, the Euroméditerranée business district, and the PACA region's commercial landscape — expertise that remote firms cannot replicate.
Direct connectivity to North Africa and the Gulf: Marseille's historic ties to Algeria, Tunisia, and Morocco complement our offices in Dubai, Riyadh, and Cairo for cross-Mediterranean mandates.
Full rights of audience before the Tribunal de Commerce de Marseille, the Cour d'appel d'Aix-en-Provence, and all regional courts — with TGV access to Paris for ICC arbitration and national regulatory matters.
Trilingual practice in French, English, and Arabic — reflecting the languages of Marseille's multicultural business community and its cross-Mediterranean client base.
GSDA's Marseille office understood both the French maritime regulatory framework and our North African counterparty's commercial expectations — they bridged two worlds that most law firms treat as separate practices.

Our Marseille team operates in French, English, and Arabic — reflecting the trilingual nature of Euro-Mediterranean business. Many of our Marseille avocats also have working proficiency in Maghrebi Arabic dialects, which facilitates direct communication with counterparties and clients in Algeria, Tunisia, and Morocco.
Marseille and Paris are connected by a 3-hour TGV service, enabling seamless coordination. Our Marseille office handles regional matters independently while partnering with Paris on cross-border mandates, ICC arbitration, and matters requiring engagement with national regulatory bodies such as the AMF, Autorité de la Concurrence, and CNIL.
