The threshold for communication with them, is non existant. I must say that there isn't any other law firm that connects with the person behind the client, as GSJ. For instance: they know my hobbies, my likes and dislikes. ’

  • ‘Joris Geens is the best environmental law attorney I know. His advice is always correct. He is also honest when something is not possible according to his client's wishes. He presents the truth. Moreover, he fights like a lion to defend his client's interests to the maximum. For me, he is a unique mix of knowledge, truth and courtesy. In addition, he teaches classes for our organization that are highly appreciated by the public.

  • 'The Real Estate and Construction practice of GSJ stands out for its in-depth knowledge of the law but also for its great experience which was built up in the last 30 years. Besides this this practise group works closely together with the colleagues of the practise group Administrative Law. As far as I know in the Belgian market (especially for Flanders) there is no other lawfirm that has such a big and impressive footprint in those combined fields of law. GSJ works for most - if not all - of the relevant construction firms and has earned a great reputation doing so. In this field of work the relevance of GSJ can not be exaggerated.'

They are very responsive and have the capability to service you on a high level on an instant basis. I am very satisfied with the work they deliver and the responsiveness.'

  • 'Christoph Lenders is my main contact at GSJ. The reason that he is my contact is that he is a very smart, experienced and very responsive lawyer. You can reach him nearly 24 hours a day. I also know that he will check the work of the less experienced associates before the work is send to me. Furthermore he knows what is important for the business. That is a special quality.'

  • ‘Although being a large and multidisciplinary office, the teams are organized in smaller, specialized expert centers. There are sufficient partners with a high level of expertise and seniority in their field. We greatly worked together with Christophe Lenders and Joris Wouters for all public and private tender contracts and specialized real estate and building topics. We worked with Yves Loix and Olivier Verhulst as specialist in spatial planning procedures and environmental laws. We worked with Bart Goossens and Geert Philipsen for author rights, deal structures and contracting issues. All of the partners stand out in their knowledge and availability.’

  • ‘One of its strengths is that it has all the disciplines needed to conduct our business. Moreover, there are good relationships and short connections between the various departments. In other words, there is efficient and intelligent internal cooperation. In addition to a good flow of information between departments, I note that there is also good sharing of information within a department. People are well informed and well trained.’

  • ‘I work on a regular basis with several partners in various discplines (contract law, spatial planning, M&A). In these collaborations, I find that these partners are distinguished by their exceptional expertise and personal commitment.’
