BELGIUM Trends and Developments

Trends and Developments Contributed by: An Weyn and Aurore Sultus Arteo Law

Arteo Law is a Brussels-based law firm founded in 2020 by members of the tax department of full-service law firm Liedekerke. Arteo focuses on tax advice and litigation; advice on wealth and estate planning; and Supreme Court procedures. The private wealth team is integrated into a very strong tax law firm, where the private client practice adopts a multidisciplinary approach, as family entrepreneurs and private clients in general often deal with a variety of related issues. Apart from needing tax advice, such clients also need

assistance in matters associated with managing and preserving family assets through controlling entities; family governance and succession planning; marital property law and inheritance law; and compliance (FATCA/CRS/UBO register). The strength of Arteo’s private client practice is that these multidisciplinary aspects can be dealt with by the firm, and that each responsible partner is personally very involved in the matter.
