Corporate Law
Sonja Geldermans advises entrepreneurs (both large and SMEs) about a variety of corporate law matters ranging from mergers, acquisitions and restructures, to internal and business disputes.
‘Corporate law is a broad and diverse field with often complex legal issues. To ensure I can provide clients with the most effective advice, I aim to thoroughly understand all aspects of a case. Based on that, I determine the way of achieving the optimal outcome for the client.’
Sonja graduated from Leiden University in 2020 with two Master’s degrees, in Corporate Law and European Law (cum laude). During her Bachelor’s degree, she successfully completed the Honours College Law programme and studied at Oxford University for a year, gaining the Diploma in Legal Studies.
After undertaking a number of internships and working at a law firm as a paralegal, Sonja joined De Clercq in September 2020.
Sonja handles a broad range of matters within corporate law, from litigating on liability issues, to drafting and reviewing contracts and advising and guiding restructuring processes.

One of the pillars of the European Union’s ESG policy is the Corporate Sustainability Due Diligence Directive (CSDDD). This directive entered into force on 25 July 2024 and still needs to be transposed into national legislation. Its aim is to ensure that large companies prevent, mitigate, or bring to an end adverse impacts on human rights and the environment as much as possible, including when these occur within their value chain.
