Marc Van tieghem

Partner, Corporate and M&A | Where legal meets business

Who am I

I am a partner in Deloitte Legal’s Corporate and M&A team, with more than two decades of experience advising clients on complex corporate challenges. I bring together deep legal expertise and a strong business mindset to help organisations navigate transactions, reorganisations, and disputes with confidence. I work closely with both private and public sector clients, combining legal precision with a pragmatic, forward-looking approach. I am active at our Antwerp office.

What I do

  • Advise clients on domestic and cross-border M&A and real estate transactions, corporate reorganisations (solvent and distressed), and corporate disputes.
  • My practice has a particular focus on the public sector (including public enterprises and public-private partnerships), shipping and port operations, and the energy and resources industries.

Who I work with

I work with a wide range of clients—from private companies and investors to governmental bodies and public sector entities. Many of my clients operate in highly regulated or infrastructure-heavy industries, where strategic decisions require balancing commercial priorities with legal and policy considerations.

My Approach

I take a solution-oriented, pragmatic approach to each matter. Whether guiding a client through a strategic acquisition, a corporate restructuring, or a sensitive dispute, I focus on clarity, actionability, and long-term impact. My goal is to help clients make confident decisions and achieve outcomes that are both legally sound and commercially viable.

Credentials and leadership

  • 25 years in multifaceted transactions and reorganisations, particularly where public interest or public funding is involved.
  • Recognised by The Legal 500 for Corporate and M&A
  • Frequent speaker and contributor to academic and professional publications
  • Member of the Brussels Bar (since 2001) and Antwerp Bar (since 2013)

Why Deloitte Legal

At Deloitte Legal, we bridge law and business. Thanks to our multidisciplinary model and global network, we connect legal, tax, financial, and regulatory perspectives to deliver integrated and forward-looking solutions. This allows me to support clients across the full lifecycle of their transactions or transformations—helping them move from legal complexity to strategic clarity.
