Known as one of the top antitrust practices in the world we are ranked in the top 10 of the legal directory GCR Global Elite. Our team of 80 specialist Antitrust lawyers works in 19 jurisdictions across Europe, the U.S. and Asia.

Having acted in some of the most exciting antitrust cases in recent years we have a sound and practical understanding of how the European Commission works. We also have good relationships with officials at all levels, both in Brussels and in all the jurisdictions where we practise antitrust law. Naturally our experience of working on cutting edge issues at the forefront of antitrust policy gives our clients a real advantage.

Our Luxembourg-based Antitrust lawyers work in close collaboration with our Brussels team to cover all aspects of Luxembourg and European antitrust law.

We handle all aspects of competition law: cartels, leniency applications, abuse of a dominant position, joint ventures, distribution systems, EU merger control, state aids and deregulation. We also advise on general EU law matters.

As well as our range of expertise, our clients benefit from our excellent relationships with the Luxembourg competition authorities, the European courts, and other national competition authorities and regulatory bodies.

Corporate and M&A

Within Luxembourg we are the legal partner of choice for some of the world's most sophisticated financial institutions, sponsors and multinational corporations.

Our clients turn to us for market-leading advice on a full range of corporate matters. These include joint ventures, mergers and acquisitions, private equity, venture capital, demergers, restructurings, and equity listings and stock exchange-related work. We also advise on  public and private company incorporations, compliance, migrations and general corporate, commercial and contract law matters.

Partners Marc Feider and Fabian Beullekens lead our award-winning team. They have led on some of the most complex and challenging deals seen in the Luxembourg market.

As well as being experts in and drivers of local Luxembourg market practice, we draw upon the expertise of our global network of offices, which enables us to understand global trends and the wider context of clients' instructions. Our lawyers are experienced negotiators, deal managers and draftsmen. We feel that these factors, as well as our responsiveness and high levels of client orientation, are why our clients come to us.

Data Protection

Our data protection practice in Luxembourg advises on all aspects of privacy and data protection law.

We have close connections with Luxembourg’s data protection authority and other Government bodies who influence privacy issues, financial sector supervision, electronic communications and eCommerce.

Having worked closely with the authority for many years we understand the sensitivities that colour this area of the law and keep abreast of regulatory developments. For example, in 2010 the authority relaxed its approach to employee monitoring.

Our experience covers drafting and reviewing corporate privacy and HR policies - including whistle blowing - monitoring the use of telephones, internet and email by employees, customer data privacy, cross-border data transfer and general compliance work.

We regularly advise the Luxembourg government on IT, digital trust and certification issues and are often involved in drafting bills and regulation. This gives us first hand knowledge of the complex issues involved.

Key contact: Katia Manhaeve

Employment and benefits

We handle both contentious and non-contentious labour law matters for employers, mainly in the banking, industrial and retail sectors, advising clients across the full range of Luxembourg employment issues.

Our lawyers provide commercial advice on contract design for individuals, flex time, retention and bonus agreements, secondment and expatriate agreements, retirement pension supplements and early retirement as well as individual dismissals and settlement agreements.

We also have a wealth of experience in collective employment issues including:

  • negotiating collective agreements/contracts

  • staff representation, including social elections

  • health and security in the workplace

  • code of ethics

  • stock options

  • collective dismissals, social plans, company agreements and mitigation plans (plan de maintien dans l'emploi)

  • internal restructuring

  • due diligence on labour law issues

Over the past years, we have advised on Luxembourg's largest social plans which reflect our innovative and pragmatic approach to sensitive issues.

Our client seminars and trainings on labour law issues can help you better understand the key legal issues.

With our strong background in contentious labour law matters, we can support you in employment-related litigation before all Luxembourg courts including the Conseil arbitral des assurances sociales.

We advise on complex cross-border financings and domestic transactions in all major financial centres worldwide.

We are placed at the heart of the Luxembourg banking and financial markets and our clients include outward looking banks and finance houses. Few practices can match the quality of our people and our pioneering expertise.

In addition to the major restructurings that took place after the 2008/2009 financial crisis, we are seeing significant changes in the Luxembourg private banking sector, following discussions over Luxembourg banking secrecy and an increase in bank mergers and spin offs.

Thanks to our well-established relationships with high profile clients, we are their chosen legal partner when it comes to critical deals.

We provide intelligent and commercial advice in:

  • Financing and lending transactions, such as acquisition finance, asset finance, Islamic finance, leveraged finance, real estate finance and syndicated lending.

  • Restructuring and insolvency.

  • Regulatory issues, such as bank licensing, bank secrecy provisions, code of conduct, consumer credit regulations, contractual terms of business and money laundering.

  • Private banking.

Debt Capital Markets

We advise major banks and corporates on all aspects of international or national debt securities transactions and many clients rely on us for our grasp of the spectrum of capital markets matters.

Our integrated ‘one firm’ approach ensures that the most complex structures can be successfully completed. We can advise on special purpose vehicles, issue documentation and security arrangements as well as negotiate advance tax agreements and assist in seeking prospectus approvals.

To ensure a legally secure environment, we talk regularly with the Luxembourg authorities.

It’s this mix of expertise and good relations that gives us both a competitive edge and the reputation for reliability that our clients have come to expect.

Key contact: Henri Wagner
Key contact: Frank Mausen

Equity Capital Markets

The mix of our local knowledge and global reach places us in pole position to structure and execute large and complex equity capital markets transactions.

The way we are organised across the world also means that cross-border work is second nature to our lawyers. This is of particular relevance with respect to IPOs of Luxembourg companies and other equity capital markets transactions as it is typical that the listing jurisdiction of the Luxembourg company is a foreign jurisdiction. These offerings can be made as parts of IPOs (primary and secondary offerings) or private placements (to be followed by a listing on a stock exchange or not) and may also be structured as a rights issue.

In Luxembourg, we advise on the full spectrum of equity and equity-linked instruments of Luxembourg companies, such as shares, warrants, convertible and exchangeable bonds.

To ensure a legally secure environment we talk regularly with the Luxembourg financial sector regulator and Stock Exchange, enjoying good relations with both. This gives us a competitive edge and the reputation for reliability that our clients have come to expect.

General lending

Our Lending practice is widely recognised as the market leader across a variety of sectors. This level of experience is vital as lenders and their clients continue to feel the effects of the financial crisis. Now, more than ever, financing transactions need to be structured and negotiated to take account of general market conditions and specific client requirements. In turn, clients need increasingly innovative and adaptable legal services from lawyers capable of offering robust advice.

That’s why clients call on us for advice. Our lawyers have the expertise to advise on any form of financing and often, the groundbreaking deals and structures we advise on become the market standard.

Our exceptional market knowledge stems from our broad client base and the experience we’ve gained in times of boom and bust. Whether we’re advising Luxembourg or international lenders or their clients, this knowledge enables us to help clients with all types of financing transactions and anticipate issues throughout the lifecycle of a matter.

Few practices in Luxembourg can match the quality of our people and our pioneering expertise. We deliver good, commercially astute advice on acquisition finance, asset finance, Islamic finance, leveraged finance, real estate finance and syndicated lending.

Our core expertise covers:

  • Structuring and setting up Undertakings for Collective Investment in Transferable Securities (UCITS), Part II funds, Specialised Investment Funds (SIFs) and SICARs.

Islamic Finance

We regularly advise clients who are interested and actively participate in Islamic finance transactions, whether that’s in the context of banking, capital markets, derivative related transactions or leasing.

We have real knowledge of this increasingly important area of the market, with a detailed understanding of the religious and legal background to Islamic finance, how the main financing techniques are evolving, the range of services offered by Islamic banks and the issues affecting the continued development of Islamic finance.

We understand the many factors that can affect an Islamic finance transaction, not least the jurisdiction in which it is carried out, the sensitive commercial issues involved and the taxation, accounting and regulatory issues that need to be considered.

Our specialist lawyers advise not only on transactional work and major projects, but also help clients produce and review their own standard form documentation. Our aim is to ensure that the transaction is structured correctly from the start, with all the important factors taken into consideration, so that the transaction can be completed successfully.

Key contact: Frank Mausen

Leveraged Finance

We are one of the leading leveraged finance practices in the market, known for groundbreaking deals and structures that eventually become market standards. Thanks to our network, we can combine a multi-jurisdictional leveraged debt team with an extensive European and US capital markets practice. This enables us to provide our clients with a full service for senior, second-lien, mezzanine and PIK debt, bridge-to-bond financings, bank/bond financings, high-yield debt offerings, securitisation take-outs and debt buy-backs and restructurings.

Our sector knowledge and understanding of our clients’ business objectives allows us to provide legal advice that truly meets those aims within the context of the overall rationale for the debt package. Lenders and borrowers alike need to be able to structure deals in ways that suit market conditions. Our lawyers can advise on any form of leveraged financing that our clients choose to undertake.

Key contact: Pierre Schleimer


We are keen to promote economic and social change in the regions where we live and work and to use our collective skills to make a difference.

One way is through microfinance, which supports the working poor. This rapidly growing sector has the potential to change the lives of millions of small entrepreneurs who depend for their livelihoods on small businesses or farms in the developing world.

Luxembourg is one of the leading jurisdictions to set up microfinance investment vehicles and, over the last 15 years, the Government has been keen to develop and advocate the potential of microfinance as a tool to fight poverty.

Our multi-disciplinary Luxembourg microfinance group can provide corporate, tax, capital markets and investment fund advice on all aspects of microfinance transactions.

Key contact: Patrick Mischo

Recognised as the market’s leading real estate finance practice, clients have described us as “pre-eminent” in Chambers & Partners. We advise the world’s most advanced investment banks, specialist real estate lenders, borrowers, funds and investors on their most critical and pioneering transactions. No other practice can match our depth of experience and unique understanding of every aspect of real estate finance in both domestic and international markets.

As financing techniques have evolved, we’ve evolved with them, cementing our reputation for leading developments in the market and structuring the most complex deals. We act on all aspects of real estate finance, on both senior and mezzanine lending and are equally adept at working on real estate related debt restructurings, CMBS originations and workouts and loan portfolio acquisitions and disposals.

It’s the mark of our Securitisation group that - in an increasingly regulated world - we can bring fresh ideas, new standards and novel structures to market.

The securitisation team works in tandem with our structured finance, derivatives and banking lawyers to meet clients' transaction needs and implement complex structures.

Luxembourg has become an important centre for securitisation transactions in recent years and more and more banks and companies are channelling their assets through Luxembourg securitisation undertakings.

As well as our track record and well-established client relations, we have excellent dialogue with the Luxembourg regulators.

It’s because of this that clients can trust us to bring innovative solutions to their most critical deals, be they distressed debt portfolios, commodities or Sharia-compliant securitisation transactions.

On IT issues, we offer technical support as well as legal expertise, drawing on our deep knowledge of IT security, IT outsourcing, domain names, e-commerce and software issues.
