Family Reunification and Partner Visas in Belgium

The sponsor's exact status, the applicant's nationality and the filing date determine the rules. Record the sponsor's card/Belgian or EU passport, the date Belgian residence over three months was first authorised, whether the family lived together in another EU state, and where the applicant is legally staying.

• Non-mobile Belgian: Article 40ter applies to a Belgian who has not genuinely exercised EU free movement. Eligible close family and sponsor-resource rules are Belgian-law rules.
• Returning/mobile Belgian: EU-family rules apply only where the Belgian genuinely resided in another EU state, family life was created or strengthened there, the relative accompanies/joins the return, and family life had not ended. Otherwise use non-mobile Belgian rules.
• EU/EEA/Swiss citizen in Belgium: Article 40bis/EU movement rules cover spouse/registered partner, descendants under 21 or dependent, dependent ascendants and facilitated extended-family/durable-partner cases. The EU sponsor must itself have a qualifying worker, self-employed, student or sufficient-resources residence basis where required.
• Third-country resident: Articles 10/10bis distinguish unlimited residence from limited A/H status, including a student. Usually only spouse/registered partner, minor unmarried children and narrowly defined disabled adult children qualify; the sponsor's permit duration can limit the family's card.
• Recognised refugee/subsidiary or temporary-protection beneficiary: use the protection-specific page. Close relatives can receive exemptions if the application and initial relationship/identity proof meet special deadlines; parents of a qualifying unaccompanied minor have a distinct branch.
• Minor Belgian/EU/protected child: the parent route has child-age, parentage, custody/dependency and actual-care tests; it is not interchangeable with joining an adult sponsor.

The 18 July 2025 law entered into force on 18 August 2025. During the two-year transition, its new provisions apply to applications filed from that date where the third-country sponsor was not already authorised/admitted for more than three months before 18 August 2025. The new provisions apply fully to applications filed from 18 August 2027. A sponsor already admitted before the cut-off may therefore remain under earlier provisions for a qualifying application filed before the full-application date. Do not use a generic online checklist: save the sponsor's first-authorisation proof and ask the competent post/municipality to name the applicable article and transition regime in writing.

Normally a third-country applicant files a family-reunification D visa at the Belgian embassy/consulate responsible for habitual residence, often through VFS/TLS. EU-family applicants who are visa-exempt may enter under their entry rules and apply municipally; a required entry visa follows an accelerated EU-family procedure. In-country filing exists only in defined lawful-stay/exemption situations. Selecting the wrong sponsor branch can change eligible relatives, age, income, fee, decision clock, annex/card and work rights.

Match the relationship to the selected sponsor route before collecting documents. A marriage must be legally valid and recognised; a previous marriage/partnership must be dissolved, and a further spouse cannot join where another spouse already resides in Belgium under a polygamous marriage.

For many third-country/protection routes, both spouses are currently required to be over 21. Some pre-existing marriages can use 18 under the route's rule; do not assume this exception applies after the 2025 reform. A registered partner must be unmarried, not in another durable relationship and not within prohibited close-relative degrees. The current durable-relationship alternatives are: at least one year continuous lawful cohabitation before filing; knowing each other for at least two years, regular contact and three meetings totalling 45 days during those two years; or a common child. Preserve registrations, travel records, dated communications and the child's act.

Children must fit the route's age/dependency definition. A third-country sponsor's ordinary branch generally covers unmarried minors; EU-family rules cover direct descendants under 21 or older dependants. Establish legal parentage/adoption, not only biological or caregiving ties. Where custody is shared, obtain the other holder's consent to relocation or a court order; include custody and habitual-residence decisions. An unmarried disabled adult child is a narrow category requiring recognised medical evidence that the child cannot support themself.

EU-family rules may include dependent ascendants and facilitate another relative who was dependent, part of the household in the origin country, or requires the EU citizen's personal care for serious health reasons, plus a durable unregistered partner. Dependency must predate or genuinely explain the move; send transfers, household registration and needs/care evidence over a meaningful period. These extended relatives do not have automatic approval merely because they are siblings or parents.

For a Belgian minor, a foreign parent must prove parentage and actual care/parental responsibility under the correct Article 40ter branch. For an unaccompanied minor granted protection, parents retain a special route; where the child turned 18 during/shortly after the protection procedure, the official page generally requires filing within three months of recognition, subject to objectively excusable force majeure.

If an authentic family act cannot reasonably be produced in a protection-family case, explain why and submit alternative valid evidence. Immigration must assess qualifying alternatives and may use interviews/investigation or propose DNA as a last evidential step. DNA is not a privately ordered shortcut and cannot prove marriage, custody or a durable partnership. Ask the Belgian post for its country-specific alternative-document list before paying for tests.

Resource, housing and insurance tests depend on the sponsor/article. Under current post-2025 third-country/protection provisions, the published reference starts at 110% of the guaranteed average minimum monthly income: EUR2,325.079 net per month, increased by 10% for each additional dependent family member. Check the live Immigration family-reunification conditions on filing day because the underlying amount is indexed.

Worked examples from Immigration: a sponsor alone in Belgium joined by partner and two children needs the 110% partner base plus 20%, currently EUR2,787.69 net monthly. If another dependent child already lives with the sponsor, add another 10%: about EUR3,020. State who is already dependent and who applies; do not apply one household figure blindly to EU-law or exempt routes.

Below the reference amount is not an automatic arithmetic refusal. Immigration must determine the actual resources needed to avoid public assistance, but the 2025 rules require the applicant to submit all information enabling that assessment. Provide 12 months where available: employment contract, payslips, account deposits, tax assessment, benefits/pension decisions, self-employed accounts/contributions, rent/mortgage, utilities, debts, childcare, maintenance and household composition. Explain variable work and recent job changes. Social-assistance income and excluded/temporary resources may not count like salary; use the route's live resource page.

Adequate housing must be normal for a comparable family and meet safety/hygiene standards. Common proof is a registered lease or ownership/title evidence plus registration and household details; upcoming 2027 implementing rules may change the required demonstration under the reform. Do not book an overcrowded address solely to obtain an application receipt. Add actual rent and bedroom/occupancy evidence if the route requests it.

Health cover must protect the sponsor and joining family in Belgium. Obtain the mutuality's prescribed certificate confirming enrolment will cover the named relatives upon arrival, or qualifying private cover where permitted; a generic EHIC/travel screenshot is not equivalent. Align the start date with travel and municipal registration.

Protection families can be exempt from resources, housing and insurance where the application is filed within six months of the protection decision, initial identity/relationship evidence is submitted with it, and completion occurs no later than ten months after the decision; exceptional objectively excusable delay must be evidenced. EU workers and certain minor-child routes have different exemptions. Create a condition table marked “applies / exempt / proof” and have the post confirm it before filing.

Download the exact checklist from the Belgian embassy/consulate responsible for the applicant's habitual residence and the matching Immigration sponsor page. The local post may use VFS Global or TLScontact, set appointment/payment methods, name approved doctors and impose recency rules. Do not copy another country's checklist or invent a universal “two blank passport pages” rule.

Build a labelled file with: application form/VisaOnWeb confirmation; current travel document and identity copies; sponsor passport/card and Belgian address; marriage/partnership, birth/adoption and previous-divorce/death acts; custody/consent; sponsor-status decision; relationship/dependency evidence; income, registered housing and insurance; adult criminal-record and medical certificate where the route requires them; photographs; fee/exemption evidence; and a cover index mapping each item to a condition. Country-specific certificates are often required to be recent, but apply only the post's stated age limit.

Check every foreign public document in the Belgian legalisation search. Depending on issuing country and act, it may need no legalisation, an apostille, or chain legalisation. Translate only as instructed, using a sworn translator whose signature/form is accepted. Obtain written quotes for issuance, apostille, courier and translation per page; names and dates must match passports. Explain spelling variants rather than altering an act.

For a missing civil act, first obtain the issuing authority's written non-availability evidence. Protection-family rules require Immigration to consider valid alternative relationship evidence in defined cases and may lead to interviews or an official DNA proposal. Do not buy an unrequested private DNA test: it does not prove custody, marriage or genuine partnership and may not be accepted. Preserve family-book records, older official files, remittances, photos and communications with dates/context.

Budget separately. Since 1 July 2026 the standard long-stay Visa D handling fee is EUR250, although family/EU/protection exemptions can apply. A separate Immigration contribution is currently EUR218 for many adult family-reunification applications to a Belgian or limited/unlimited third-country resident; minors, EU-family and specified protection relatives may be exempt. Other categories can differ. Pay only the amount shown on the live official contribution page with the exact structured reference; wrong/missing proof can make the file inadmissible and refusal does not normally refund it. External-centre service/courier fees, medical exam, criminal record, legalisation, translation, DNA if officially offered, travel and municipal card are additional.

Before the appointment, scan the complete file, keep originals in checklist order and verify payment reached the correct official account. Never transfer a “release” or “guarantee” payment to an agent/private account. A realistic budget should show official fees plus quoted local costs and an arrival reserve, not pretend one national total covers every issuing country.

For the ordinary third-country route, submit the D-visa file to the Belgian post competent for habitual residence, using VisaOnWeb and its embassy/VFS/TLS appointment process. Keep the submission receipt and Immigration file number; use the official visa tracker/My File rather than paying an intermediary. A post may issue directly only where authorised; otherwise it forwards the file to Immigration.

The statutory decision clock depends on the article - commonly six months for Belgian/EU-family municipal cases and up to nine months for many third-country family files, with legally permitted extensions in complex cases. Protection, student and special branches must use their current published clock. Count from an admissible/complete filing as the notice states, not from booking an appointment. If overdue, request status with the file number and consider a lawyer/formal notice; silence is not approval.

In-country filing is not a universal alternative. It is available for specified applicants already holding lawful limited residence, visa-exempt short stay, a D visa for marriage/legal cohabitation after the event, or another statutory exception. Confirm the exact branch before short-stay days expire. A municipal intake receipt or Annex 19ter records a particular EU/Belgian-family application; it does not by its name alone guarantee work, travel, re-entry or approval. Get written confirmation of each right and expiry date.

After a D visa is issued, check its dates/annotations, carry the relationship and sponsor copies at the border, and travel while it is valid. Report to the municipality of actual residence within eight days of arrival where the D-visa route requires it. Bring passport/visa, sponsor, housing and civil documents, photos and local fee. The municipality opens registration, police verify actual residence, and the route leads generally to an A card for family of a third-country limited-status sponsor or an F card for a qualifying third-country family member of an EU/mobile Belgian/non-mobile Belgian. The exact validity follows sponsor/route; EU relatives receive their relevant EU document.

Ask the municipality for: issued annex and expiry; police-check contact/correction route; card type, price and collection/PIN timing; National Register number; labour-market wording; health-insurance start; renewal deadline; and travel/re-entry evidence while the card is produced. Do not start work merely because an application is pending. The card/annex annotation and regional employment rules control; employers can verify the labour-market statement.

If the police check fails because of timing, nameplate or access, contact population service immediately with lease, occupancy evidence and availability rather than filing at a false address. Do not leave Belgium while a short-stay/pending document is the only evidence without asking whether a return visa or new entry visa is required. Track every expiry and submit missing items through the official channel with proof of delivery.

Approval is the start of a conditional residence period, not the end of administration. Read the visa, annex and card: record card type, “labour market” wording, validity, sponsor link and renewal window. An F card generally evidences EU/Belgian-family residence; an A card usually follows the limited duration of the third-country sponsor. Register with the mutuality, obtain eID/itsme access where supported, and preserve the decision plus every document used.

Apply for renewal before expiry using the municipality's stated window. Provide continued cohabitation/family life, sponsor status, income/housing/insurance where still required and any changed passport/civil record. A pending renewal may produce Annex 15, but ask what rights it preserves and whether travel/re-entry is safe. Do not assume five years automatically produces permanent or independent residence; route, continuity, absences and card history must be assessed.

Report a genuine address or household change. Death, divorce, annulment, end of partnership or the sponsor leaving Belgium does not always mean immediate loss: EU-family retention rules can protect a spouse/child after minimum marriage/residence periods, custody/access, death, or particularly difficult circumstances; third-country family members have route-specific autonomous-residence provisions. Collect work, children, custody, school, integration, violence and residence evidence and seek advice before signing deregistration or missing renewal.

If there is domestic/intrafamily violence, safety comes first. Call 101 for immediate police danger or 112 for emergency assistance; use confidential regional violence services/shelter and a lawyer. Belgium has residence-protection guidance for victims admitted through family reunification. Keep police/medical reports, messages, shelter/social-worker statements and proof of household status where safe, but lack of one report should not prevent seeking protection. Do not remain with an abuser solely because they threaten to cancel the card; only authorities decide residence.

A refusal, inadmissibility, withdrawal or order to leave must state authority, reasons, notification date, remedy and whether it suspends execution. Family-reunification decisions are generally challenged before the Council for Alien Law Litigation, often within 30 days of notification, but the decision controls and some urgent/detention deadlines are shorter. An annulment appeal does not automatically suspend every measure; a suspension request, including extreme urgency, may be needed. Contact an immigration lawyer/legal-aid bureau immediately and preserve the envelope/e-notification.

Sometimes Immigration accepts a limited reconsideration request for specified missing-proof situations, but this is a favour, not a substitute for appeal. File any new application only after checking stay/work consequences and whether circumstances changed. For delays, incorrect registration or card errors, complain first to the responsible post/municipality/Immigration with the file number, then use its ombuds/appeal route without letting the legal deadline expire.
