Sarah Marangoni


I am dual qualified as a French Avocat and an English Solicitor. I am a consultant resident in Buckles’ London office, and a manager at CastaldiPartners, working with the International, Company Commercial and Dispute Resolution teams.

I have worked in France and in England, with a focus on international and cross border situations dealing with intellectual property, commercial and corporate contracts and immigration law. 

Within my corporate and commercial activity I have been involved in publishing, media and in the consulting sector of scientific research, dealing with institutional bodies as well as with multinational corporations. 

I’m trilingual in Italian, French and English, and thanks to my international background I have been able to assist clients in cross border and multicultural/multilingual matters. I am a member of the Immigration Law Practitioners’ Association.

I hold a Masters Degree (LLM) in Intellectual Property and European Competition Law from UCL (University College London), a Post Graduate Degree (DEA) in International Private Law from Paris Pantheon- Sorbonne University and a Law Degree (Maitrise) from Paris II Assas University.

When not assisting clients, I co-fund and manage a startup that applies recent research in neuroscience. Lastly, I, along with my family and friends, take full advantage of London’s cultural scene.

  • Sarah Marangoni has been instrumental to draft and help in the execution of a commercial agreement for UV under UK law. The process from inception to finish has been smooth and the advice received allowed us to come out smarter and feel comfortable on the terms and outcome.
