    Kind: deeplink-after-auth · Delivery: sync-pdf-download

    Primary actor: both

    Handoff: auth-wall

    Agent does: I'll send you to the Brussels Irisbox quicklink for the marriage certificate. The link asks Irisbox to generate your marriage act as a PDF as soon as you sign in.

    You do: Sign in with itsme or your eID. Irisbox will generate your marriage act and download it. Save the PDF to your Be Civic folder.

    To resume: Tell me 'got it' when the PDF has downloaded. I'll mark the marriage certificate as obtained and move on.

    The steps after authentication / handoff are described from documentation, not yet confirmed by a real Be Civic user. If reality differs, please tell us so we can fix the entry.

    Each use generates a real document delivery — only click when you actually need the document.

    Agent does: I'll read the Wallonia civil-status extracts page to confirm the commune-routing instructions and quote them back to you.

    You do: None — the agent handles this source fully with no customer action required.

    To resume: After reading the page I'll recommend the federal Just-on-Web handoff next, or the offline commune visit if neither works.

  3. Federal authenticated portal · priority 60

    Regions: federal

    Authentication: csam (itsme, eid, mygov.be, smart-id)

    Kind: deeplink-to-auth-wall · Delivery: user-driven-after-auth

    Primary actor: user

    Handoff: full-takeover

    Agent does: I'll point you to Just-on-Web's civil-records extracts surface — the federal equivalent of Brussels Irisbox for non-Brussels residents. Sign in with CSAM, pick 'Acte de mariage' / 'Huwelijksakte', and download the PDF.

    You do: Authenticate via CSAM. Choose the marriage-certificate extract; the portal will deliver a PDF. Save it to your Be Civic folder.

    To resume: Tell me you have the PDF. If Just-on-Web does not list the certificate (it sometimes happens for older marriages), the offline route at your commune of marriage is the fallback.

    The steps after authentication / handoff are described from documentation, not yet confirmed by a real Be Civic user. If reality differs, please tell us so we can fix the entry.

  4. Offline commune visitfallback only · priority 10

    Regions: brussels, wallonia, flanders, federal

    Kind: commune-visit · Desk: Service État civil / Dienst Burgerlijke Stand · Delivery: in-person-or-postal

    Primary actor: user

    Handoff: physical-presence

    Agent does: I'll prepare what you need to ask for: an extract or copy of your acte de mariage from the commune where the marriage was registered (the lieu de mariage, not necessarily your commune of residence). Bring your eID; small fee (often €0–€10).

    You do: Go to the Service État civil (or Dienst Burgerlijke Stand) of the commune where your marriage was registered. Ask for an 'extrait' or 'copie intégrale' of the acte de mariage. Some communes accept postal or email requests — check first.

    To resume: Bring the document back and confirm receipt. If the marriage was registered abroad and is not in the Belgian BAEC, the certification-of-foreign-documents flow applies instead — flag this and I'll route you to the apostille / consular-legalisation sub-skills.

    The steps after authentication / handoff are described from documentation, not yet confirmed by a real Be Civic user. If reality differs, please tell us so we can fix the entry.

    Notes: Always-available fallback per graceful-degradation. Note: Belgian marriages from abroad may not be in BAEC; foreign-document certification flow applies in that case.
