Van der Feltz Advocaten

What Van der Feltz Advocaten does

Van der Feltz Advocaten N.V. is an independent Dutch law firm founded in 2006 and headquartered in The Hague. The firm is a 26-lawyer boutique structured as a N.V. (naamloze vennootschap), with team composition of 6 partners, 1 counsel, 6 senior associates, and 11 associates, supported by an office director and administrative staff. It operates at the niche intersection of public and private law, focusing on four verticals: Construction & Real Estate, Energy, Government, and Industry. Core practice areas include administrative law, spatial planning, environmental and permitting law, public procurement, expropriation, energy law, construction and real estate law, and cassation (Supreme Court) litigation. Notable clients include Tata Steel, Chemours/DuPont, the Province of South Holland, the Municipality of Dordrecht, De Nederlandsche Bank, SNS Bank/Reaal, Natuurmonumenten, a global pharmaceutical company, a large Dutch real estate developer, and various Randstad municipalities.

The firm's value proposition rests on the integration of public and private law expertise delivered by an academically credentialed team — nearly all lawyers teach at universities or publish in academic journals, and partner Jacques Sluysmans holds a professorship of expropriation law at Radboud University. The firm is independently ranked Band 1 (Willem Bosma) and Band 2 (firm) in Chambers Europe 2026 for Public Law: Planning & Environment, Tier 1 in Legal 500 for Environment and Planning, and recognised in Construction, Real Estate, and Energy. It has no proprietary technology platform and uses standard legal practice management tools.

Van der Feltz operates a pure professional services model with hourly billing (no overhead surcharge), separately invoiced disbursements, monthly or progress-based invoicing, a 14-day payment term, and optional retainers. Go-to-market is sales-led and relationship-driven, supported by content marketing (a Dutch-language blog, Cassatievlog video series, newsletter via MailChimp), events (e.g., Provada Vastgoedlunch Seminar), academic publishing, and prominent display of Chambers and Legal 500 rankings. Distribution is direct-to-client from a single The Hague office at Javastraat 22; the firm serves primarily Dutch-domiciled public and private clients with limited cross-border matters. Revenue is not publicly disclosed, and the firm has remained independent since founding with no evidence of external investment or acquisition.

Broad incumbents

• NautaDutilh: Major Amsterdam-based Dutch firm with strong practices in real estate, energy transactions, and regulatory law. While broader and larger, NautaDutilh overlaps with Van der Feltz on Dutch real estate development and energy infrastructure mandates.
• CMS Netherlands: The Dutch arm of global law firm CMS Derks Star Busmann, with established practices in real estate, construction, energy, and administrative law. Competes with Van der Feltz for similar Dutch and EU-cross-border mandates, particularly in regulated industries.
• Loyens & Loeff: Major Benelux law and tax firm with strong real estate, energy, and tax law practices. While tax-heavy, Loyens & Loeff overlaps with Van der Feltz on real estate transactions, energy regulation, and expropriation-adjacent matters, particularly through its Dutch office.
• De Brauw Blackstone Westbroek: Premier Amsterdam-based Dutch law firm with a broad full-service practice that includes regulatory, real estate, energy, and administrative law. While much larger and broader than Van der Feltz, De Brauw competes for the same high-end Dutch regulatory and Supreme Court mandates and represents a reference benchmark for top-tier Dutch legal work.

Direct peers

• AKD: Rotterdam-based Dutch firm with a deep construction, real estate, and government practice. AKD competes for the same municipal, developer, and infrastructure mandates as Van der Feltz, including zoning, expropriation, and procurement matters in the Randstad.
• Van Doorne: Amsterdam-based Dutch firm with a focused real estate, construction, and government practice that closely mirrors Van der Feltz's specialisation mix. Competes for the same Dutch developer, contractor, and public-sector mandates.
• Dirkzwager: Arnhem-based Dutch firm with a strong construction law and civil cassation practice, often cited alongside niche Dutch construction specialists. Comparable to Van der Feltz in size, specialisation, and clientele of contractors, developers, and government entities.
• Stibbe: Major Amsterdam-headquartered Dutch law firm with comparable practices in real estate, energy, environment & planning, and administrative/procurement law. Stibbe is a direct competitor for the same Dutch institutional and corporate clients (Van der Feltz counsel Ronald Olivier previously worked there), and offers comparable Supreme Court litigation depth but at materially larger scale.
• Pels Rijcken: The Hague-based firm historically known as the 'State's lawyer' (advocate of the Dutch State). Pels Rijcken competes with Van der Feltz on the same government-side administrative law, spatial planning, and cassation mandates, and shares the same The Hague ecosystem as the anchor.
• Houthoff: Amsterdam-based Dutch law firm with one of the strongest real estate and construction practices in the Netherlands. Houthoff routinely competes with Van der Feltz on large Dutch real estate development, leasing, and construction disputes and shares a similar premium-niche positioning in built-environment law.
