Although European's General Data Protection Regulation(GDPR) directly applies in all European Union (EU) member, each state interprets and applies the GDPR differently because of two reasons: The GDPR itself allows member states to create and apply different rules on around 50 areas of the regulation, and each EU member state’s Data Protection Authority and its national courts interpret and enforce GDPR in their own ways, different from each other.
Therefore, businesses should pay attention to each EU member state’s interpretation of the EU GDPR and their national data protection laws. In this article, we will focus on one of the key EU countries' data protection law regimes: Belgium.
Belgium data protection law in a nutshell
In Belgium, two key laws apply to the processing of personal data:
- Europe's General Data Protection Regulation (GDPR)
- The Act of 30 July 2018 on the protection of natural persons with regard to the processing of personal data ('the Act”).
When does the Belgium privacy law apply and how? Let's look at it in detail.
Personal scope
Both public and private entities fall under the scope of the Act and the GDPR.
However, public authorities and their appointees and agents cannot be subject to administrative fines under Article 83 of the GDPR.
Territorial scope of the law
The Act applies to the processing of personal data when this processing takes place in the context of activities related to the establishment of a controller or processor in Belgium. Furthermore, it is irrelevant whether the actual processing is carried out in Belgium or not.
However, if a data controller located in another EU country uses a data processor established in Belgium, the law of that EU country will apply to the data processing, not the Belgian Data Protection Act.
The Act becomes applicable even when a controller or processor that processes the personal data of people in Belgium is not established in the EU if the processing activities relate to:
- The offering of goods or services, irrespective of whether a payment from the data subject is required, to such data subjects in the Belgian territory; or
- The monitoring of their behavior as far as it takes place within the Belgian territory.
What is the relationship between the Act and the GDPR
The Act implements the EU GDPR and also covers matters that are left to the discretion of EU member states under the GDPR. For example, the Act incorporates the following changes as allowed under the GDPR:
- Creating exceptions to the fulfilment of data subject rights based on scientific and historical research purposes
- Setting the age limit for consent to 13, instead of 16

Key requirements of Belgium data privacy law and how to comply

The key requirements of Belgium's Data Protection law are highly similar to the GDPR, subject to minor differences as allowed by the GDPR. To process personal data in accordance with Belgian law, you need to comply with the following requirements:
Comply with the six fundamental principles of the GDPR
When you collect, use, share, and process personal data, you must adhere to the six fundamental principles of the GDPR:
- Data should be processed fairly, lawfully, and transparently;
- You should only collect data for specific, explicit, and legitimate purposes and not process it in a manner incompatible with those purposes;
- Personal data shall be adequate, relevant, and not excessive to what is necessary considering the purpose of data processing;
- Personal data must be accurate and, where necessary, up to date;
- Personal data shall be kept in an identifiable form for no longer than necessary;
- Personal data shall be kept secure.
Demonstrate your compliance
Article 5(2) of the GDPR requires you to demonstrate how you comply with these six principles. This is referred to as the “accountability principle”. You need to implement appropriate documentation and technical measures to have proper proof of your compliance efforts.
For example, you may demonstrate your compliance with GDPR principles by doing the following:
- Signing data processing agreements with your vendors,
- Carrying out data protection impact assessments before you start collecting and using personal data in certain circumstances,
- Keeping records of all data breaches
Identify and document a legal basis to process personal data
When you collect, use and process personal data, you must rely on one of the six bases listed in article 6 of the GDPR. These legal bases include ‘consent’, ‘legitimate interests’, and ‘ contractual necessity’.
When you rely on consent, obtain consent in a GDPR-compliant way
When you rely on data subjects’ consent to collect and process personal data, consent must satisfy GDPR standards.
Valid consent under the GDPR must conform to the following:
- Freely given: Individuals must have a genuine choice as to giving or refusing to give consent.
- Specific: Consent should be for a specific data processing activity and for a purpose.
- Informed: You must be transparent to individuals about how you collect and use their data. For instance, You must provide individuals with clear information about your identity, and explain the purposes for data processing and each data processing activity.
- Unambiguous: Consent should be affirmative.
Additionally, keep in mind that organizations must document and keep records of all consents provided.
Satisfy data subject requests
Individuals are entitled to the following rights related to their personal data:
- Right to be informed
- Right to access
- Right to rectification
- Right to erasure
- Right to object/opt-out
- Right to data portability
