Catherine Warin

Avocate - Associate

I find fascinating how law comes to life in concrete and complex situations. This is the reason why I commit to working on each single case carefully, creatively and resolutely in order to design personalized solutions. I rely on my academic expertise and my practical experience in administrative law and in general civil law and litigation, with a special interest in European and transnational issues.
