Justion Advocaten

What Justion Advocaten does

Justion Advocaten is an independent Dutch law firm structured as a partnership (maatschap) of ten partners, founded in 1999 by Jolanda van Koeveringe-Dekker as Justion Adviesgroep and headquartered in Middelburg, Zeeland. The firm operates across four offices in the Netherlands (Middelburg, Rotterdam, Terneuzen, and Breda) and comprises approximately 25 lawyers and legal professionals supported by expert administrative staff, serving clients nationwide with a primary geographic concentration in southwestern Netherlands.

The firm's practice spans 15 legal specialisms with particular depth in the technically demanding intersection of civil and administrative law — including government liability, state aid, procurement law, environmental and area development law, real estate and construction law, rental law, education law, water board law, and employment law — supported by notable talent such as Paul Adriaanse, a guest professor of constitutional and administrative law at Universiteit Leiden. Clientele comprises Dutch municipalities, provinces, water boards, semi-government bodies, housing corporations, educational institutions (primary through university level), liability insurers, and small-to-medium enterprises as well as larger corporates across construction, healthcare, recreation, and fisheries. The firm also operates the Woon&Co sub-brand, a free knowledge-sharing and networking network for housing corporations, real estate organisations, and municipalities.

Revenue is generated through hourly-fee-based legal advisory and litigation services billed monthly, with disbursements, a percentage-based office cost surcharge, and VAT billed separately; fees are indexed annually to the Dutch CBS consumer price index (CPI 2015=100), with invoices payable within 14 days. The firm invests in client knowledge through content marketing (insights articles, newsletter) and community events, and maintains a multi-language digital presence (Dutch, English, German, French, Greek, Turkish). No disclosed use of AI technology underlies operations; business is generated via partner-led, relationship-driven advisory and litigation mandates across its specialisms.
