Recognized in Best Lawyers since 2027 
Sónia Antunes Dias has been part of VCA since 2007 and is a Senior Associate in the Litigation and Maritime Law teams. With more than 20 years of experience in legal practice, she represents individuals and companies in civil, administrative and maritime matters, keeping her clients’ interests at the centre of how she builds each case.
Maritime Law sits at the heart of her practice. Sónia holds a postgraduate degree in the field and advises on maritime litigation and ship registration, with particular experience in the International Shipping Register of Madeira (MAR). She also reviews and negotiates purchase agreements for recreational vessels, guiding clients through each stage of the acquisition.
In Administrative Litigation, she represents individuals and companies before the administrative courts, defending their rights and legitimate interests. Sónia’s work in Administrative Law was recognised by her peers in the 2027 edition of The Best Lawyers in Portugal™. Her civil litigation work combines technical rigour with a clear strategic sense and covers civil liability claims, disputes arising from breach of construction contracts, and actions to set aside transactions made to the detriment of creditors (actio pauliana). She also handles criminal matters.
For many years, Sónia has supervised and trained trainee lawyers in civil, administrative and maritime law, guiding them through the realities of day-to-day practice — from case strategy and legal drafting to court appearances and client relations. Alongside the technical side of the profession, she passes on the values that shape her own work: rigour, integrity and dedication to the people she represents.
