Belgium Legal Cohabitation: Stable & Lasting Relationship Evidence PDF
Belgian family reunification for unmarried partners runs through the legal cohabitation route (cohabitation légale / wettelijke samenwoning), administered by the Office des Étrangers (Dienst Vreemdelingenzaken — IBZ). Both partners must be at least 21 years old (or 18 if they had already lived together for at least one year before the sponsor moved to Belgium), both unmarried and not in another registered partnership, and the relationship must be “stable and lasting” under Belgian law. The applicant applies for a Type D long-stay visa at the Belgian embassy or consulate; once the cohabitation is registered with the Belgian municipality, the applicant receives a Belgian residence card.
Visa Types
- D Visa — Legal Cohabitation (Cohabitation Légale / Wettelijke Samenwoning)
- D Visa — Intent to Marry or Legally Cohabitate
- Family Reunification — Registered Partner
Why Chat Evidence Matters
Belgium’s legal cohabitation route is one of the clearest cases in Europe where chat evidence directly supports a statutory requirement. The Immigration Office explicitly accepts “telephone, correspondence or electronic messages” as proof that partners maintained regular contact — one of the three legal paths to demonstrate a stable and lasting relationship (the others are one year of prior continuous cohabitation, or a mutual child). A chronological WhatsApp/Messenger/Telegram record showing regular contact over at least two years, alongside the three required visits totalling 45+ days, directly maps to this third path.
Evidence Requirements
- Identity & Civil Status: Valid passport (typically with at least 6 months’ validity), passport-sized photos, and proof that the applicant is currently unmarried and not in another registered partnership (sworn affidavit or civil-status certificate, apostilled where required).
- Sponsor’s Status in Belgium: Copy of the sponsor’s Belgian ID card or residence permit, plus a recent Belgian civil-status certificate (État civil / Burgerlijke stand) issued by the sponsor’s municipality.
- Stable and Lasting Relationship (one of three legal paths): Path A: Proof of at least one year of prior continuous cohabitation in Belgium or another country. Path B: Proof that you have known each other for at least two years AND maintained regular contact (phone, mail, electronic messages) AND met three times in those two years for a total of at least 45 days. Path C: A mutual child. Most international couples rely on Path B.
- Sponsor’s Sufficient Income: Proof that the sponsor has stable, regular, and sufficient means of subsistence to support both partners without becoming a burden on Belgian social assistance. Typical evidence: employment contract, recent payslips, tax returns.
- Adequate Housing: Proof of housing in Belgium suitable for both partners — lease agreement (with registration), property deed, or comparable documentation.
- Health Insurance: Proof that the sponsor holds Belgian health insurance (mutualité / mutualiteit) covering the household. Visa applicants typically also need Schengen-compliant travel/medical insurance with minimum EUR 30,000 coverage valid in the Schengen area.
- Communication, Visit, and Relationship History Evidence: Chronological overview of the relationship plus supporting evidence: WhatsApp/Messenger/Telegram messages, telephone bills, money transfers, photographs across different dates, previous visa stamps, flight tickets and hotel invoices for visits, money transfers, and signed declarations from friends and family.
Step-by-Step: Create Your Evidence PDF
- Confirm you meet the legal cohabitation conditions — Both partners are 21+ (or 18+ if you cohabited at least one year before the sponsor’s arrival), both unmarried and not in another registered partnership, and you can demonstrate a stable and lasting relationship via one of the three legal paths.
- Export your chat history covering at least two years — Export your WhatsApp, Telegram, Instagram, or Messenger history. For Path B (the most common route), the law expects evidence of regular contact over at least two years prior to the application.
- Upload to PartnerProof — Drop your export into PartnerProof. All parsing and PDF generation runs locally in your browser — your messages never reach any server.
- Select Belgium or a European destination — Choose Belgium (or a European preset) from the country selector. PartnerProof applies A4 paper size and DD/MM/YYYY date formatting.
- Build a chronological overview of the relationship — Use the timeline view to organize messages and the gap indicator to flag any silences. The Belgian checklist explicitly asks for a concise chronological overview of the relationship — keep the PDF focused, not exhaustive.
- Add visit evidence (3 visits / 45+ days) — Upload flight tickets, hotel invoices, passport stamps, and photos from each visit. PartnerProof interleaves these with messages so the 45-day requirement is easy for the case officer to verify.
- File the D visa at the Belgian embassy / consulate — Submit the visa application in three sets (one original, two copies) at the Belgian embassy or consulate competent for your residence. Once granted, travel to Belgium, register the legal cohabitation at your sponsor’s municipality, and obtain your Belgian residence card.

Frequently Asked Questions
Are WhatsApp messages valid evidence for Belgian legal cohabitation?
Yes. The Belgian Immigration Office explicitly accepts evidence that partners maintained regular contact by “telephone, correspondence or electronic messages” as one of the three legal ways to prove a stable and lasting relationship. A chronological WhatsApp, Messenger, or Telegram record over two years directly maps to this requirement when combined with the required 3 visits / 45 days.
What does “stable and lasting relationship” mean under Belgian law?
The law sets three alternative paths: (1) at least one year of prior continuous cohabitation in Belgium or another country; (2) knowing each other for at least two years, maintaining regular contact (phone, mail, electronic messages), AND meeting three times in those two years for a total of at least 45 days; or (3) a mutual child. Most international couples qualify under path 2.
How do I document the “3 visits / 45 days” requirement?
Submit flight tickets and boarding passes, hotel invoices or accommodation evidence, passport stamps (entry/exit), and dated photos for each visit. Lay them out chronologically so the case officer can quickly verify that you met at least three times and that the total time together meets or exceeds 45 days in the two years preceding the application.
How does the application process work?
The applicant files a Type D long-stay visa application at the Belgian embassy or consulate competent for their residence, typically in three sets (1 original + 2 copies). The Immigration Office in Belgium decides on the file. Once the visa is granted and the applicant arrives, they register the legal cohabitation at the sponsor’s Belgian municipality and receive a Belgian residence card.
Will the Immigration Office check whether our partnership is genuine?
Yes. If the Immigration Office doubts whether the partnership reflects a real intention to build a long-term life together, it can invite either partner for an interview, request additional evidence, and consult the public prosecutor’s office. A well-organized, honest evidence PDF — messages, photos, visit history — makes it easier to answer consistently.
