Tan Advocatuur is a boutique law firm specialised in
Supreme Court litigation


Our focus is Supreme Court litigation. We combine the legal quality of the traditional Supreme Court bar with the service level of a top-tier law firm. We do that through clear advice, effective litigation, fast communication and transparent fee arrangements.


Robbert was sworn in as attorney in 2008, when he joined De Brauw Blackstone Westbroek (in The Hague, Amsterdam, London). There, he specialised in Supreme Court litigation and complex commercial and corporate disputes. In 2017, he went on to found Tan Advocatuur.

Robbert read Law at Utrecht University (LLB, LLM) and Chinese studies at SOAS, University of London (MA), in addition to periods studying Art History and Law at the universities of St Andrews and Cambridge.

He has particular expertise in procedural, tort, contract and company law, in addition to class actions. Next to law, art has his particular interest.
