Luxembourg is not only the home of numerous EU institutions but has also long been an international hub for financial services, investment funds, holding structures, and complex regulatory business models. To navigate the legal landscape here, you need more than knowledge of the law. You need a deep understanding of economic realities, cross-border structures, and tax dynamics.

Arendt & Medernach combines all of this – and more. The firm stands for a new type of legal advice that goes beyond analysis, seamlessly integrating guidance, strategy, and implementation. For businesses, financial institutions, and international investors, Arendt is now the first point of contact in Luxembourg.

„We don’t just advise, we shape.“

This is the firm’s self-understanding – and it is put into practice. Rather than stepping in only when a problem becomes acute, Arendt accompanies its clients from the early stages of a project. Whether it’s company formation, regulatory setup, or transnational expansion – Arendt’s lawyers, tax experts, and specialists think ahead and create structures that are both legally solid and economically viable.

This holistic approach sets Arendt apart from traditional law firms that tend to be reactive. The firm offers a partnership based on mutual respect, not legal distance.

An Interdisciplinary Approach with Over 1,300 Employees

With over 1,300 employees – including several hundred specialized lawyers – Arendt is Luxembourg’s largest business law firm. Size is not for its own sake, but the result of a sustainable quality approach. The firm combines legal, regulatory, and tax expertise into cross-functional teams that deliver practical solutions to complex issues.

Today’s businesses face numerous challenges in demanding environments, including:

• ESG regulation and sustainability reporting

• Digitalization in the financial sector and fintech compliance

• Cross-border tax structuring

• European capital market rules and AML/CFT obligations

Arendt addresses these issues not just with legal provisions but with an understanding of systems. The firm’s experts comprehend business logic, assess risks, and formulate their recommendations in ways that decision-makers can immediately apply.

Industry Expertise That Delivers Results

A key feature of Arendt is its deep industry expertise. The firm has dedicated teams working in specific sectors, including:

• Banks and financial institutions

• Investment funds and asset managers

• Private equity & venture capital

• Real estate companies and developers

• Public sector and state institutions

The firm’s advice is not only legally excellent but also strategically tailored to industry dynamics. Two recent examples underline the firm’s capabilities:

• Belfius Bank received legal support from Arendt in acquiring one-third of the asset management company Candriam – a complex deal that required regulatory finesse and precise contract drafting.

• Alvotech, a biotechnology company, relied on Arendt’s expertise for its triple listing on the New York, Frankfurt, and Luxembourg stock exchanges. This case highlights Arendt’s international coordination skills and speed of implementation.

Recognized Excellence, Internationally Acknowledged

Arendt & Medernach is regularly recognized by leading industry publications. In 2024, Chambers Europe named the firm the “Luxembourg Law Firm of the Year.” It also consistently ranks at the top in Who’s Who Legal, Legal500, and the IFLR Europe Awards.

A key reason for this success is the firm’s consistent integration of Legal Tech, data analysis, and digital project management. The firm employs automated review processes, intelligent contract analysis, and digital case management to deliver fast, precise, and robust solutions that meet growing demands.

Multiplying Expertise: The Arendt Institute

A unique feature of Arendt is its in-house Arendt Institute, which serves as a practical training center for clients, employees, and external experts. The institute combines current knowledge with practical relevance.

Its offerings include:

• Workshops on Anti-Money Laundering (AML) & Counter-Terrorism Financing (CFT)

• Training on ESG reporting

• Intensive courses on capital markets and corporate law

This commitment to knowledge is systematic: § 4 BBiG (Vocational Training Act) emphasizes that continuous professional development is essential for sustainable quality, and Arendt implements this rigorously. Clients not only benefit from personalized advice but also gain access to top-tier legal knowledge.

A Law Firm with Purpose

Behind Arendt’s success is a strong value foundation. The firm sees itself as a strategic partner with responsibility – for its clients, its employees, and the legal system. Issues such as compliance, diversity, sustainability, and governance are firmly embedded in the firm’s culture.

The firm is also engaged socially, through pro bono projects, promoting legal talent, and initiatives for digital ethics. The firm’s credo: Excellence obliges – not only to clients but also to society and the future.

Conclusion: A Strategic Firm for Strategic Action

For companies operating in Luxembourg or seeking cross-border investments, a partner who provides more than just legal advice is essential.
