The advocate listed above has registered the following principal (and secondary) legal practice areas in the Netherlands Bar’s register of legal areas:

1. Jasper Helder is registered for Administrative law (EU law)

Based on this registration, he is required to obtain ten training credits per calendar year in each registered principal legal practice area in accordance with the standards set by the Netherlands Bar.

Jasper’s practice encompasses a wide range of trade, regulatory, contentious and transactional matters. He focuses on international trade and corporate compliance regarding sanctions, export controls, national security, anticorruption and anti-money laundering (AML). He also advises on other aspects of trade regulation, including customs, trade remedies, free trade agreements and rules of origin.

With his experience in developing strategies to face regulatory challenges and working with regulators, Jasper helps clients see around corners in dealing with the complexities of doing business in geopolitically challenging and highly regulated industries and jurisdictions.

Jasper conducts regulatory and internal investigations, preparing voluntary disclosures and negotiating these to a regulatory resolution/settlement, including in the context of criminal matters.

In addition, Jasper advises senior executives and companies on self reporting, the development of compliance programs, as well as mitigating compliance risks in corporate transactions and representation before regulatory agencies and institutions. Jasper’s deal work includes providing counsel on mergers & acquisitions (M&A), joint ventures (JVs), due diligence, shareholder issues and other corporate (governance) advice.

Clients call upon Jasper for strategic planning, bespoke solutions and a path forward in the face of high-stakes regulatory issues. With the client’s business objectives front of mind, Jasper provides direct, timely and pragmatic advice, drawing on his deep, detailed experience with regulatory agencies. He is routinely successful in resolving regulatory issues and disputes for clients.

Jasper’s clients include multinational companies headquartered in Europe, the United States, as well as foreign subsidiaries of Russian companies. He provides advice to clients across sectors, from energy (upstream & downstream), semiconductor and hi-tech, aerospace & defense, shipping, to commodity trading, private equity, private credit, sovereign wealth funds and other investment management businesses.

His work usually involves multiple jurisdictions, including European Union (and EU member states), as well as the United Kingdom, United States and Switzerland. Much of his work involves the interaction between U.S. sanctions, export controls and national security regulation and other jurisdictions, including the compliance impact of local laws and “blocking regulations.”
