The firm: JahaeRaymakers was established in 2015 by Carel Raymakers  Jurjan Geertsma, Thom Dieben and Han Jahae.  They find common ground in their ambitions in the field of economic and international sanctions law and in risk and reputation issues. Dian Brouwer (litigation and investigation) and Cathalijne van der Plas (asset tracing and recovery) join the partnership in 2019 and 2020 respectively. In 2022 Susanne van Breukelen (corporate criminal law) joined the partnership.

Areas of practice: JahaeRaymakers is a leading niche firm, specialising in the law of economic sanctions and the international law of sanctions, as well as risk and reputation issues. Its lawyers act as trusted advisors for a wide range of public authorities, (listed) companies, museums and their directors, and high-profile and other private individuals. They have detailed knowledge, a wealth of experience and an excellent international network.

Trust, discretion, quality and tenacity are paramount in the often precarious and sensitive cases handled by JahaeRaymakers. The firm’s aim is to achieve adequate solutions for every issue. It is down-to-earth, creative and open-minded. Wherever possible their lawyers act before problems reveal themselves, preferably in the background and out of court. If necessary, the firm fights in court to the limit for each client.

Each lawyer or employee within the firm puts his or her own special expertise at the service of specific issues and problems of our clients. They do this as a team. The cooperation between them is extremely close and that with (international) external lawyers and experts excellent.
