The Aliens Act defines as vulnerable persons: minors (accompanied and unaccompanied), disabled persons, pregnant women, elderly persons, single parents with minor children and persons having suffered torture, rape or other serious forms of psychological, physical or sexual violence.[1] The Reception Act mentions more profiles, and reflects the non-exhaustive list contained in Article 21 of the recast Reception Conditions Directive, referring to “children, unaccompanied children, single parents with minor children, pregnant women, disabled persons, victims of human trafficking, elderly persons, persons with serious illness, persons suffering from mental disorders and persons having suffered torture, rape or other serious forms of psychological, physical or sexual violence, such as victims of female genital mutilation.”[2] However, there is no common policy, both regarding the asylum procedure and reception, to address the situation of all vulnerable applicants.[3]


Screening of vulnerability

Both the Immigration Office and the CGRS have arrangements in place for the identification of vulnerable groups. The Immigration Office has a “Vulnerability Unit” to screen all applicants upon registration on their potential vulnerability. The Vulnerability Unit consists of officials interviewing vulnerable cases who have had specific training and are trained to identify vulnerabilities and to conduct interviews with persons with a vulnerable profile.[4]

The Immigration Office uses a registration form in which it is indicated if a person is a (unaccompanied) minor, + 65 years old, pregnant, a single woman, LGBTI, a victim of trafficking, victim of violence (physical, sexual, psychological), has children, or has medical or psychological problems. [5] These categories offer a broader definition than the one provided in the Aliens Act and the Reception Act.   The form further offers an empty space for additional information, often used in practice to indicate urgent needs, e.g. medical needs. The registration process will be faster for vulnerable asylum seekers, and certain reception centres, such as emergency centres, will not be assigned to them by Fedasil.

Similarly, at the CGRS level, there are few specific provisions regarding the screening, processing and assessing of vulnerabilities of asylum seekers. There is a general obligation to consider the asylum seeker’s individual situation and personal circumstances, particularly the acts of persecution or serious harm already undergone, which could be regarded as a specific vulnerability.[6] In case of a gender-related claim, applicants can refuse being interviewed by a protection officer from the other sex or with the assistance of an interpreter from the other sex.[7] Whether unaccompanied or accompanied, children should be interviewed in appropriate circumstances, and their best interests should be decisive in the examination of the asylum application.[8]

At the moment of registration, unaccompanied children applying for asylum are handed the brochure “Guide for the unaccompanied Minor who applies for asylum in Belgium”, published by the CGRS in different languages. The Aliens Act also has specific provisions on the procedures for unaccompanied children when they do not apply for asylum. Unaccompanied children should always be accompanied by their guardians during interviews. In contrast, accompanied children who apply separately or who request to be heard by the CGRS during the procedure of their parents should only be accompanied by the lawyer and person of trust during the first interview. If there are more interviews at a later stage, the CGRS can also interview the child alone.[9]

At the CGRS, two vulnerability-orientated units have been established that render support to protection officers dealing with such cases:

  • A “Gender Unit” trained following the EUAA module on Gender, Gender Identity & Sexual Orientation helps ensure that gender-related applications for international protection are adequately addressed. Gender-related asylum applications include claims based on sexual orientation, gender identity or sexual characteristics (LGBTI), fear of undergoing Female Genital Mutilation (FGM), honour crimes, forced marriages, domestic violence, sexual violence;[10]
  • A “Minors Unit”, headed by an appointed coordinator, ensures a harmonised approach, information exchange and exchange of best practices. Unaccompanied minors are only interviewed by specially trained protection officers, who follow the EUAA training module on Interviewing Children.[11]


Age assessment of unaccompanied children

The Guardianship service has the general mission to streamline a system of tutors (guardians) intended to find a durable solution for unaccompanied children who are not EU citizens in Belgium, whether they apply for asylum or not (see Legal representation of unaccompanied children). The service must first control the identity of the person who declares or is presumed below 18.

If the Guardianship service itself or any other public authority responsible for migration and asylum, such as the Immigration Office, has any doubt about the person concerned being underage, a medical age assessment can be ordered at the expense of the authority applying for it.[12]

During the reception crisis in December 2021 (see Country Report: Belgium – 2021 Update), Fedasil and the Immigration Office briefly conducted a screening of minors waiting in line at the arrival centre based on physical appearances. If a young man waiting in line did not look like a minor, he was sent to the line of single men resulting in a denial of reception. This practice being in clear violation of the legal framework, it was promptly stopped after an intervention from the Flemish Children’s Rights Commissioner.[13]

Also, in the context of the reception crisis, no age assessments were conducted between 16 October and 13 December 2022. According to the Guardianship Service, asking minors without access to reception to undergo an age assessment was not justified. As a result, these minors were not given access to the reception network and could not dispute the doubt about their minority. In the second week of January 2023, Caritas International Belgium reported that 24 of these minors were gone missing. No similar reports were made in 2023.

Age assessment in Belgium consists of scans of a person’s teeth, wrist, and clavicle. These scans determine the developmental stages of a person’s bones and teeth. Thus, when the applicant’s age is unknown, it is estimated by comparing their development stage to that of persons in the reference study population.[14] Following critiques around the accuracy of the medical test to establish the age of non-Western children by order of Physicians,[15] a margin of error of 2 years is considered. This means that only a self-declared child tested to be 20 years of age or above will be registered as an adult.

An applicant may challenge an age assessment before the Council of State through a non-suspensive appeal. However, the court is not competent to review elements such as the reliability of the medical examination results or the evidentiary value of identity documents. It can only check if the competent authorities had the right to conduct an age assessment according to the law. This procedure is lengthy, often taking longer than a year, so the person often becomes an adult before the Council of State has reached a final decision. Accordingly, the procedure is not an effective appeal and has been met with criticism.[16]

In 2015, the Council of State had to reaffirm, by suspending several Guardianship Services’ decisions, the legal provision that of the different outcomes of the different subtests of which such an age assessment consists, the one that indicates the lowest age is the one binding for the Guardianship Service’s decision.[17] Despite these judgements, it still occurs that the Guardianship Service does not automatically use the lowest age as the one binding for the decision. If this happens, the Council of State suspends the decision.[18]

The Council of State further decided that the Guardianship Service is not competent to assign a date of birth to the person who is declared a minor following an age test but for whom the margin of error of the age test results in a higher or lower age than the age declared.[19] The Guardianship Service stated it would no longer disregard the declared age of a minor, even if estimates as higher or lower than the margin of error. However, the Guardianship Service indicated that the difference between the declared age and the minimum age indicated by the margin of error needs to be reasonable. If a minor is declared 13, and the age assessment suggests that the minor is 17, this is not considered a reasonable difference. In such a case, the Guardianship Service might still use the age indicated by the age assessment.[20]

At the end of 2021, the Belgian government announced the creation of an expert committee tasked with evaluating the medical methods used during the age assessment and ensuring all the hospitals conducting these medical methods use the same methodology.[21] In 2022, the expert committee published 17 proposals on optimising the methods used during age assessment and how to come to a uniform age assessment procedure.[22]

In 2023, 4,366 unaccompanied children were registered in the country, a decrease of 32.7% compared to 2022.[23] Of this group, 2,594 applied for asylum.[24] 87% were boys, compared to 13% girls. Among those, 26% are from Afghanistan, 18% are from Eritrea, and 15% are from Syria.

The top 5 nationalities (among the signalisation) were:

In 2,199 cases, doubt was expressed about the age of the declared minors. In 1,727 cases, an age assessment was conducted. Of these assessments, 1,282 found the declared minor to be over 18 years old.[26]
