Our team of over 100 lawyers in our Brussels and Antwerp offices provides a full legal service to leading local and international corporations, financial institutions and public entities.

Belgian Law Firm of the Year (Chambers Europe award 2020)

Having been in the market for more than 40 years, our Belgian clients appreciate our natural understanding of their industry and background. International clients come to us for our knowledge of the 'ins and outs' of doing business in Belgium.

The majority of our work is complex, large scale, urgent and international in nature. Unlike the majority of law firms in Belgium we provide clients with a full service covering: corporate, M&A, finance, litigation, commercial contracts, employment and benefits, intellectual property, IT, outsourcing, real estate, tax, environment, EU and competition and public law, and are consistently ranked first tier across most of these areas. This means our clients receive relevant, commercial advice with all perspectives integrated, without the need to piece together a jigsaw puzzle of input from different law firms.

Clients benefit from our seamless integration across legal practice areas and into Allen & Overy's international network, ensuring the sharing of knowledge, information, technology systems, processes and skills.

Our experience

Experience highlights

Experience highlights

Studio 100 and its existing shareholders (Gert Verhulst, Hans Bourlon and BNP Paribas Fortis Private Equity), on the sale of approximately 25% of Studio 100’s share capital with the Swerts family ('Soudal') and 3d Investors. Studio 100 is a Belgian entertainment company. The company produces television programs, music, films and has a number of theme parks in Belgium and beyond.

The deal was run as a private placement auction process, and attracted extensive press coverage.  Due to the diverse nature of the interested bidders combined with the fact that we represented 3 different existing shareholders with each their own interests and sensitivities, the drafting and negotiation of transaction documents was more complex than in an average M&A deal. In addition, the deal was also complex due to the complex nature of the target business, active in various juridictions. 

SeaMade wind farm

Otary and SeaMade in respect of the development of two new offshore wind farms off the Belgian coast – the single largest wind farm ever financed and built in Belgium

The Mermaid and Seastar offshore wind farms (together, merged into “SeaMade”) consist of 58 wind turbines 38-50km off Zeebrugge, which are expected to deliver renewable energy for 485,000 households. Intended to bring about a reduction of 500,000 tons of CO2 emissions per year, the project is crucial to help Belgium reach its renewable energy objectives. Allen & Overy took the lead role on the financing of the project, the negotiations of all major project agreements, regulatory questions, state aid aspects, as well as the merger of the two corporate special purpose vehicles, Mermaid and Seastar.


The European Investment Bank on its financing of the Oosterweel Connection – the largest infrastructure project in Belgium, and one of the largest in Europe. It is an important part of the Antwerp Master Plan 2020, which provides for additional road infrastructure, public transport projects, extra cycle paths and water-related infrastructure works.

Domo, a Belgian chemical company, on aspects of a complex €1.6 billion deal that saw BASF, Solvay, and Domo Chemicals agree to acquire Solvay’s polyamide business.

BASF agreed with advanced materials and specialty chemicals company Solvay to acquire its integrated polyamide business in 2017, but the deal was only cleared by the European Commission in 2019, and as a condition, Solvay had to dispose of its European polyamide business (known as “PA6.6”) to a third party.

Domo’s acquisitions include engineering plastics operations in France and Poland, high performance fibres in France, polymer operations in France, Spain, and Poland, and commercial businesses in Germany and Italy. The acquisition strengthened Domo’s nylon-based engineering plastics and created a European leader with scale, entering the market with a top position in PA6/6.



Athora Holding Ltd. (together with its subsidiaries) on the €540 million acquisition of Generali Belgium S.A., the Belgium-based subsidiary of international insurance group Assicurazioni Generali S.p.A. The buyer in this case was a different type of investor than those we usually see on FIG deals. Many of the usual investors on FIG deals are themselves established financial institutions, but Athora is an insurance-focused investment fund (backed by US PE fund Apollo).

Allfin on its merger with Immobel, the listed Belgium-based real estate developer. This transaction creates the largest listed real-estate development group in Belgium.


Advising Nenskra, a special purpose vehicle of the Korean state owned company K-Water and the Georgian government, on its procurement process for the building of a dam in Georgia. A number of international financial institutions, including the European Investment Bank, are involved with regard to the financing of the project. The procurement process is therefore held in accordance with the principles of the EIB procurement guide.

A sustainable oil producer on the restructuring of its Belgium-based operations. The restructuring required sophisticated advice during the information and consultation phase as well as during the negotiations with trade unions, and for the establishment of termination packages.

Novartis Novartis on its first ever ‘telehealth’ project relating to the development of a new internet-enabled device for the treatment of patients.

Patrizia Immobilien on the acquisition of the Astro Tower from Santander.



BNP Paribas Fortis on the financing of the public takeover bid by TVH Group of the UK listed Lavendon Group, which is one of the largest public take-over bids launched by a Belgian family-owned business.

Waterland on the financing by ING Belgium NV, Belfius NV and KBC Bank NV, as lead arrangers, of its investment in United Petfood Producers, a manufacturer of dry pet food with activities in Belgium, France and Poland.

The Mandated Lead Arrangers in respect of USD700m borrowing base facilities for OW Bunker & Trading A/S following bankruptcy of the global OW Bunker Group. This was the largest bankruptcy in the shipping industry in recent years.

Goldman Sachs on the refinancing of Group Bernaerts holding office buildings and logistic facilities in Mechelen and Antwerp.

Bond issues for VGP, Allfin, Matexi and Ethias The issuers or arrangers on a large number of bond issues for VGP, Allfin, Matexi, Deceuninck, AB InBev, Penates Funding, Elia and Ethias.

IPOs of Asit Biotec, Bone Therapeutics and Celyad We have been instructed on most of the Belgian IPOs since 2008. We worked with Bone Therapeutics on its Euronext Brussels and Paris IPO. Additionally, having advised Celyad (at the time Cardio3 BioSciences) on its Euronext Brussels and Paris IPO, we consequently worked with its team on the EU aspects of its USD100.1m NASDAQ IPO and on its EUR32m pre-round private placement with investors in the U.S. and Europe.
