Moore Law Acquires Four & Five to Boost Tech and IP Legal Expertise

Belgian law firm Moore Law, part of the Waterland-backed Moore Belgium group, has acquired Four & Five, a boutique legal practice specializing in technology, intellectual property (IP), investment transactions, and legal support for start-ups and scale-ups. Announced on June 4, 2026, the acquisition strengthens Moore Law’s position in the Belgian legal market by expanding its specialized expertise and enhancing its service offering to innovative and high-growth businesses.

While the financial terms of the transaction remain undisclosed, the acquisition involves a full integration of Four & Five’s operations into Moore Law. Post-acquisition, Tom Vanraes, Managing Partner of Moore Law, and Anneleen Vander Elstraeten, Managing Partner of Four & Five, will serve as co-Managing Partners of the combined entity, signaling a collaborative leadership approach.

Moore Law is a well-established Belgian law firm known for its personalized client service and broad legal expertise. Four & Five, by contrast, has carved out a niche in advising technology companies, managing intellectual property rights, and guiding start-ups and scale-ups through investment and growth challenges.

The strategic rationale behind the acquisition centers on expanding Moore Law’s service offerings in the technology and start-up sectors. By incorporating Four & Five’s IP and investment advisory capabilities, Moore Law aims to cross-sell services to a broader client base and deepen its engagement with high-growth companies. This move also reflects growing demand for specialized legal support in technology innovation and entrepreneurial ecosystems.

Industry observers note that the Belgian legal market is experiencing increased consolidation, particularly among firms targeting technology and start-up clients. Moore Law’s acquisition of Four & Five positions it to better compete with peers by offering a more comprehensive suite of services tailored to emerging sectors.

Financial details such as deal value, revenue multiples, or funding sources were not disclosed. However, the integration is expected to generate operational efficiencies through shared administrative functions, consolidated office resources, and streamlined marketing efforts. The combined firm also anticipates enhanced client service through a broader legal skill set and stronger leadership.

Looking ahead, Moore Law plans to focus on seamless integration of client management systems and operational processes while retaining key talent from both firms. The co-Managing Partner structure aims to align firm cultures and ensure continuity for clients during the transition.

Overall, this acquisition marks a significant step in Moore Law’s growth strategy, reinforcing its commitment to supporting entrepreneurs and technology-driven businesses. The firm expects to leverage the combined expertise to capture increasing demand for IP and start-up legal services in Belgium’s evolving market.
