Felix Felleisen

Felix Felleisen, a partner at Deloitte Legal Germany, has been named M&A Lawyer of the Year in Germany at the Corporate INTL Global Awards 2025. A German-qualified attorney-at-law with more than twenty-five years of transactional experience, he is one of the most consistently recommended corporate and mergers and acquisitions practitioners in the German market.

Mr Felleisen joined Deloitte Legal Germany in 1999 and was admitted to the partnership in 2006. Over the course of his career he has advised clients on the full range of corporate law, M&A and corporate restructuring matters, with a particular emphasis on transactions that carry a cross-border dimension. Within the firm he heads the Private offering and leads the Spanish Desk, and he is also a member of the Dutch Desk — roles that reflect both his seniority and the international reach of his practice.

His transactional work covers the acquisition and disposal of companies and businesses, joint ventures, and the corporate reorganisations that so often accompany or follow a deal. Clients value his ability to steer complex negotiations to a conclusion, and his standing has been recognised for fifteen consecutive years in the JUVE guide, which has listed him as a frequently recommended lawyer for both corporate law and M&A. Commentators quoted there have described him as quick, assertive, internationally experienced and an excellent M&A lawyer with a good sense of humour — a combination that serves clients well in high-pressure situations.

Much of Mr Felleisen's recent activity has been at the intersection of M&A and private equity, where he has led Deloitte Legal teams on significant transactions for institutional investors. These have included exits and acquisitions for the software-focused investor Main Capital Partners and other strategic investments in German technology and software companies, underlining his familiarity with the demands of financial sponsors and the sectors in which they are most active.

Deloitte Legal Germany provides a distinctive platform for this work, combining the legal expertise of a substantial law firm with the multidisciplinary strength of the wider Deloitte organisation. The firm supports clients across the whole spectrum of M&A advice, from complex transactions to joint ventures, compliance and antitrust questions, and it is able to draw on tax, financial and advisory colleagues to deliver integrated solutions. Its stated philosophy — offering business-oriented solutions to legal problems and legal solutions to business issues — resonates strongly with the way Mr Felleisen approaches transactions.

That integrated model is particularly valuable in mergers and acquisitions, where legal, tax and commercial considerations are inseparable and where general counsel and chief legal officers increasingly look for advisers who can help them deliver results while managing risk and controlling cost. Mr Felleisen's experience allows him to sit at the centre of such deals, coordinating the various strands and keeping the transaction moving toward completion.

The Corporate INTL award recognises both the longevity and the quality of Mr Felleisen's M&A practice. For companies, investors and management teams contemplating a sale, acquisition, joint venture or restructuring in Germany or across borders, he offers seasoned, internationally minded counsel backed by the full multidisciplinary resources of Deloitte Legal.
