Legal Internships in Belgium 2026 — Stage & Trainee Positions
The Belgian legal profession is built on the stage — a three-year supervised training period that is mandatory for all aspiring advocates. Beyond this formal requirement, Belgium also offers a range of internship opportunities at EU institutions, international organisations, and corporate legal departments. This guide covers everything you need to know about legal internships and trainee positions in Belgium for 2026.
The Belgian Stage System Explained
The stage is the most important internship in Belgian legal practice. It is not an optional career enhancement — it is the mandatory pathway to becoming a qualified avocat (French) or advocaat (Dutch).
How the Stage Works
- Duration: Three years of supervised practice under a qualified patron (supervising lawyer).
- Registration: Stagiaires register with their bar association — OVB for the Dutch-speaking bar or AVOCATS.BE for the French/German-speaking bar.
- Work: Stagiaires work at law firms handling real cases, appearing in court, drafting legal documents, and advising clients — all under the patron's guidance.
- Training: Mandatory attendance at CAPA (Certificat d'Aptitude à la Profession d'Avocat) courses covering ethics, practice management, and professional skills.
- Pro bono: Required participation in the legal aid system (bureau d'aide juridique).
Finding a Stage Position
Securing a stage position with the right patron and firm is crucial for career development. Here is how to find one:
- University career services: Belgian law faculties maintain strong relationships with leading firms and can facilitate introductions.
- Bar association listings: Both OVB and AVOCATS.BE maintain registries of patrons accepting stagiaires.
- Job platforms: Browse stage positions on LegalAlphabet Belgium Internships.
- Direct applications: Contact firms listed in our Top Law Firms in Belgium guide directly — many recruit stagiaires through informal channels.
- Networking: Attend bar events, university seminars, and the annual Rentrée judiciaire to meet potential patrons.
Compensation During the Stage
Stage compensation varies significantly by firm type and location:
| Firm Type | Typical Annual Salary (EUR gross) |
|---|---|
| Magic Circle / US Elite Firm | 50,000 – 70,000 |
| Large International Firm | 40,000 – 60,000 |
| Leading Belgian Firm | 35,000 – 50,000 |
| Mid-Size Belgian Firm | 25,000 – 40,000 |
| Small / Solo Practice | 18,000 – 30,000 |
Note that stagiaires at the Belgian bar are technically self-employed (independent contractors), which has implications for tax and social security. For full salary data across career stages, see our Legal Salary Guide Belgium 2026.
EU Institution Internships
Belgium's unique position as home to EU institutions creates exceptional internship opportunities for law students and graduates:
European Commission — Blue Book Traineeship
The European Commission offers five-month paid traineeships (stages) starting in March and October each year. Legal trainees are placed in Directorates-General including DG COMP (Competition), DG JUST (Justice), and the Legal Service. The monthly grant is approximately EUR 1,300. Competition is intense, with thousands of applications for several hundred positions.
European Parliament
The Parliament offers Robert Schuman traineeships for university graduates, including placements in the Parliament's Legal Service. These five-month placements provide insight into EU legislative processes.
Court of Justice of the European Union
While based in Luxembourg, CJEU stages are highly sought by Brussels-based law graduates. Trainees assist Advocates General and Judges with legal research and opinion drafting.
European External Action Service (EEAS)
Offers traineeships in EU delegations worldwide and in Brussels, including positions focused on international law and human rights.
International Organisation Internships

Law Firm Summer Programmes
Several international firms in Brussels offer structured summer programmes or vacation schemes for law students:
- These programmes typically last two to four weeks and provide exposure to the firm's practice areas.
- They serve as a recruitment pipeline for future stage positions.
- Application deadlines are usually in January–March for summer placements.
- Both Belgian and international students are eligible, though language requirements apply.
Corporate In-House Internships
Major companies with Belgian operations offer legal department internships:
- Pharmaceuticals: UCB, Janssen (J&J), and GSK have significant Belgian legal teams that host interns working on regulatory, IP, and commercial matters.
