Notary and legal document services website cost in Antwerp: local agencies vs Kolonell (2026)

The verdict in three sentences

In Antwerp, a website for a notary office (notariskantoor) costs, as a 2026 order of magnitude, 6 000 to 28 000 EUR at a local agency, and noticeably more when three languages are needed. Kolonell delivers deed pages, document checklists and online booking at a fixed price of 2 700, 4 500 or 8 200 EUR, with English and French written natively for the international clients of the port, the diamond trade and real estate. Dutch, the office's working language, is supplied by you or quoted separately: that is the point to weigh honestly against an Antwerp agency.

What sets a notary website apart in Flanders?

The Belgian notary is a public officer appointed by the King, a member of a provincial chamber and of the federal notariat, whose public portal notaris.be already informs the general public at length. Your site does not need to explain everything again: it should show your office, your deeds, your practical lead times, your team and how to book. Notarial ethics limit commercial tone: no comparison with colleagues, no promises, sober information.

For many deeds, Belgian notary fees are set by regulation, and registration duties fall under the Flemish Region. What visitors want above all is to understand what they will pay in total: a clear page separating fees, administrative costs and taxes, with a link to the notariat's calculation tools, saves many phone calls.

Antwerp's clientele is varied: Dutch and international buyers in Zuid or Eilandje, families in the diamond sector, port and chemical companies, and young firms incorporating a BV under the 2019 Code of Companies and Associations, with a financial plan. In Flanders, deeds are in principle drawn up in Dutch, with translation for parties who do not understand it: the site should say so plainly.

Compliance, kept factual: the GDPR applies, enforced in Belgium by the Data Protection Authority. The national register number and ID card copies do not go through a standard web form, but through a secure upload tool. Apostilles for Belgian documents are handled by the FPS Foreign Affairs. WCAG 2.1 AA is the accessibility reference; the European Accessibility Act, applicable since 28 June 2025, covers certain services. This is not legal advice.

What do an Antwerp agency, a freelancer and Kolonell cost?

What does each package include for an Antwerp office?

A custom cost simulator, a client portal or an online sales module is an application quoted on request, as is ongoing SEO.

What is the three-year cost of a trilingual site?

Scenario: Dutch, French and English. Kolonell maintenance after support is quoted on request: same assumption on both sides.

If your clients are almost entirely Flemish, a Dutch-only site from an Antwerp freelancer will cost less: Kolonell only makes sense if French-speaking and international clients matter.

Which questions should you ask providers?

• Who writes each language, and who checks Belgian notarial terminology?
• Does the site separate fees, costs and duties without promising a final amount?
• Does the tone respect professional ethics: no comparison, no promise?
• Where are uploaded documents stored, and for how long?
• Are access and the domain in your name?

Mini case study

Illustrative example. Elke D., partner notary in a nine-person office in Berchem, receives more and more French buyers and foreign port executives. An Antwerp agency quotes 16 500 EUR for a trilingual site, photos included. Kolonell proposes Premium at 8 200 EUR; the team adapts the existing Dutch copy, a sworn translator reviews terminology for 900 EUR and a local photographer is booked for 700 EUR.

Kolonell total: 9 800 EUR, a 6 700 EUR gap at build, at the cost of about three days of internal work on the Dutch.
