Prior to joining Leiden Law School, Matthias Haentjens was an attorney with De Brauw Blackstone Westbroek. In  this capacity, he handled cases both as a transaction lawyer and as a (supreme court) litigator.

Matthias studied Greek and Latin at the University of Amsterdam (BA cum laude), and obtained his Master degree in 2001. He became a teacher of classics, but subsequently obtained a Master degree in Law (cum laude) in 2003, also at the University of Amsterdam. He obtained his PhD at the University of Amsterdam in 2007 and was a visiting scholar at Université de Paris II (Panthéon-Assas), Harvard Law School and New York University School of Law.

Title of dissertation / oration / key publications

Matthias’ key publications include ‘The Law Applicable to Indirectly Held Securities’, a book on conflict of laws rules in the context of international securities transactions (published in 2006), and his dissertation, ‘Harmonisation of Securities Law, Custody and Transfer of Securities in European Private Law’ (published in 2007 with Kluwer Law International). More recently, he contributed to the book ‘Regulating Unfair Banking Practices in Europe’ (A. Ciacchi & S. Weatherhill eds., published in 2010 with Oxford University Press).

His inaugural address was entitled: "The Alchemist's Autonomy: A Private Law Principle in Banking and Finance" (in Dutch, published with Boom).


Matthias is primarily interested in the way in which systems of law deal with international financial developments and its innovations. His fields of interests include international financial law, insolvency law, and private law (general). He assisted in the proceedings of the Unidroit Convention on Substantive Rules Regarding Intermediated Securities in Rome, and has published nationally and internationally on securities custody and transfer law, but also on other matters of (international) private law.
