In Belgium, the land registry is not publicly accessible. Unlike other EU member states where a simple online search suffices, identifying the holder of a property right on a parcel requires going through regulated administrative or professional channels. Here are the concrete steps, their legal limits, and the shortcuts that popular articles overlook.
Notarial access via eNotariaat: the fastest way to identify an owner
Belgian notaries have direct and centralized access to cadastral data, including the identity of the owner, through the federal application eNotariaat. This platform aggregates information from the SPF Finances, the Mortgage Registry, and the cadastre into a single entry point.

For a purchase project, contacting a notary often allows obtaining the information within a few days. The notary simultaneously checks mortgage charges, easements, and the history of transfers, which goes far beyond simply identifying the owner.
We recommend this route whenever there is a transactional interest. The consultation fees remain modest compared to the time lost in traditional administrative procedures. To find out who owns a house in Belgium in an acquisition context, this is the most reliable and comprehensive method.

Cadastral extract via MyMinfin: online procedure and access conditions
The SPF Finances provides the MyMinfin portal to order a cadastral extract. This document includes parcel data, the cadastral income, and, depending on the type of extract requested, the identity of the registered owner.
The process is entirely online. Payment is made via Bancontact, and the extract is available directly in the MyMinfin interface after processing. Two types of extracts deserve to be distinguished:
- The “heritage” cadastral extract lists the real estate properties attached to an identified natural or legal person, along with the cadastral income of each parcel.
- The cadastral plan (or parcel plan) provides the geographical boundaries of the parcels, without necessarily mentioning the name of the current owner.
- The “by parcel” extract identifies the owner(s) linked to a specific cadastral reference, provided that this reference is known in advance.
The difficulty lies in the fact that, without knowing the cadastral division and parcel number, the search is impossible on MyMinfin. To obtain these references, the parcel plan (accessible via the regional geoportal or CadGIS) is the mandatory starting point.
Municipal urban planning offices: an underutilized local alternative
In recent years, several Walloon and Brussels municipalities have strengthened their housing or urban planning offices to allow on-site consultation of the owner’s identity. Liège, Namur, and Brussels-City are among the administrations that offer this service, usually by appointment.
A legitimate interest must be justified: purchase project, health issue, neighborhood dispute, urban planning permit request. Simple curiosity is not sufficient. The urban planning service accesses the cadastral data from the SPF Finances and can provide orally or in writing the name of the registered owner.
This route is particularly suitable when the targeted parcel is located in the municipality of the applicant’s residence. The timeframes vary from one day (at the counter) to a few weeks (by mail), depending on the local administrative workload.
GDPR constraints and legitimate interest: what blocks a property owner search in Belgium
The Belgian legal framework prohibits free access to property data for the general public. The EU e-Justice portal explicitly confirms this: Belgium is among the member states where no online database allows for the free identification of a landowner.
Any request for nominative cadastral information requires demonstrating a legitimate interest under GDPR and Belgian tax legislation. Acceptable reasons include:
- A documented real estate acquisition project (ongoing offer, search mandate)
- A legal dispute requiring the identification of the owner (neighborhood disturbance, contested easement)
- A public interest mission (urban planning, health, expropriation)
- An inheritance procedure involving a specific property
Requests made without justification are systematically rejected by the SPF Finances. Municipalities apply the same filter. We observe that this point is rarely detailed in online guides, which imply that a simple form is sufficient.
Mortgage Registry: researching the complete history of a property
Beyond the cadastre, the Mortgage Registry office (part of the General Administration of Heritage Documentation) keeps the history of transfers, mortgages, and seizures on each parcel. A mortgage search provides not only the current owner but also the chain of previous owners and the charges affecting the property.
This search is fee-based and requires knowing either the name of the presumed owner or the cadastral reference of the parcel. It remains the only method to obtain a complete and enforceable history against third parties.
Notaries systematically use it during a sale. An individual can also request it, always subject to justifying a legitimate interest.
The distinction between cadastre and Mortgage Registry is fundamental: the cadastre identifies the tax owner, while the Mortgage Registry establishes the legal owner. In the case of an unregistered succession or a recent sale, the two sources may temporarily diverge. For real estate due diligence, both consultations are complementary.
