Dependent Proof for Student Spouse and Kids 2026: Documents That Actually Work (Marriage, Birth, Cohabitation)

Dependent Proof for Student Spouse and Kids is where most applications slow down, not because people lack documents, but because they submit the wrong versions, the wrong formats, or proof that doesn’t line up across names, dates, and addresses.

Always confirm prices and policies on the official site, because immigration offices, consulates, and visa centers can change checklists and formatting rules without notice.

Quick Answer (Read This First)

• Prioritize civil-status documents first: marriage and birth records usually carry the most weight for Dependent Proof for Student Spouse and Kids.
• “Certified copy” often beats a plain photocopy, especially when the issuing country is outside the EU.
• Long-form records (with parent details and registration info) are usually stronger than short forms.
• Cohabitation proof works best as a bundle (lease + bills + bank), not a single paper.
• Translations matter, a great document can still be rejected if it’s not translated as required.
• Legalisation or apostille can be the difference between “accepted” and “unverifiable”.
• Name consistency across every document is the fastest way to avoid delays.

Luxembourg context that affects what “works”

For Luxembourg, family reunification and dependent residence routes are tied to defined family relationships, financial capacity, housing suitability, and valid health insurance. Official government guidance is the best place to confirm what applies to your status and household size, including how the process is staged before and after entry (temporary authorisation, then visa if needed, then local steps after arrival). Use Luxembourg family reunification steps as the reference point when you’re checking document format and timing.

Even when the relationship proof is perfect, Dependent Proof for Student Spouse and Kids can still fail if the “supporting conditions” don’t match, like housing capacity or coverage for everyone. That’s why the strongest submissions look consistent as a full file, not just a stack of certificates.

12 documents that actually work for Dependent Proof for Student Spouse and Kids

1) Official marriage certificate (civil registry)

This is the core document for spouse-based Dependent Proof for Student Spouse and Kids. A government-issued marriage certificate shows a legally recognized relationship, typically with names, date, place, and registration authority. For most visa and residence procedures, it’s the main item that ties your partner to the sponsor.

Strong submissions usually rely on originals or certified copies, not informal prints. If the certificate isn’t in an accepted language for the receiving authority, it often needs a certified translation and, in many cases, legalisation or an apostille.

Submission readiness checklist

1. Full names match passports (including accents and hyphens).
2. Date and place of marriage are visible.
3. Issuing authority and registration number appear.
4. Certified copy or original is included.
5. Translation is attached when required.
6. Apostille or legalisation is attached when needed.

2) Marriage registration extract (population register excerpt)

A marriage registration extract can work as strong supporting evidence when it’s issued by a national or municipal register and shows the same marriage event as the certificate. It’s often used when the “certificate format” varies by country, or when the authority prefers registry proof that can be verified quickly.

This document helps in Dependent Proof for Student Spouse and Kids because it also tends to reflect updated name changes or corrected civil status, which can reduce mismatch issues when a spouse changed surname after marriage.

3) Family book or household record (where issued)

Some countries issue a “family book” or household register document listing spouses and children under one family unit. When it’s issued by a government authority and kept current, it can be a helpful bridge between marriage and birth proof, especially for families with multiple children.

It doesn’t replace separate birth certificates in many systems, but it can strengthen Dependent Proof for Student Spouse and Kids by showing the family structure in one official record.

4) Wedding photos with date-linked proof (supporting, not primary)

Photos aren’t legal proof by themselves, but they can support credibility when paired with something that anchors the date and event. Useful pairings include wedding invitations, venue invoices, hotel bookings, or a registry appointment confirmation that matches the marriage date.

For Dependent Proof for Student Spouse and Kids, photos are best treated as a small, neat appendix. A few clear images with both partners, family members, and recognizable context often work better than dozens of random selfies.

Practical photo set ideas

• A photo showing both partners and close family
• A photo at the ceremony with identifiable venue details
• A photo with a dated invite or printed program beside it
• A photo showing rings, certificate moment, or registrar setting

5) Affidavit of marriage or relationship (supporting statement)

An affidavit is a signed statement describing the relationship, usually notarized. It’s commonly used when official records exist but don’t tell the full story, like second marriages, complex name changes, or countries with delayed registration practices.

For Dependent Proof for Student Spouse and Kids, affidavits are typically supporting evidence. They work best when they’re specific, factual, and backed with attachments, rather than emotional stories.

Common attachments that strengthen an affidavit

• Passport ID pages for both partners
• Evidence of shared address history
• A short timeline of the relationship
• Copies of key civil-status records

6) Proof of registered partnership or PACS (where applicable)

If the relationship is a registered partnership (not marriage), proof usually needs to show the registration authority, effective date, and current status. The biggest difference is that acceptance can be more conditional, so the best files include both the partnership record and stronger cohabitation proof.

EU-level guidance about who counts as a family member and what proof is commonly expected can be helpful background when comparing categories. See EU family member guidance for Luxembourg.

7) Child’s long-form birth certificate (with parent details)

For children, a long-form birth certificate is usually the most effective document because it clearly shows the child’s identity and the legal parents. The strongest versions list the child’s full name, date and place of birth, and both parents’ names (and sometimes their dates of birth).

For Dependent Proof for Student Spouse and Kids, long-form records often reduce follow-up requests because the link between sponsor and child is explicit, not implied.

Key fields that usually matter

• Child’s full name (matching passport)
• Date and place of birth
• Mother’s full name
• Father’s full name (if applicable)
• Registration number and issuing authority

8) Hospital birth record (supporting if civil record is delayed)

A hospital birth record can support cases where civil registration is delayed or where the child’s official certificate is being re-issued due to errors. On its own, it often doesn’t carry the same legal weight as a civil registry birth certificate, but it can strengthen a file during transitions.

For Dependent Proof for Student Spouse and Kids, it’s most useful as an add-on that explains timing, especially for newborn applications where the passport and civil certificate issuance don’t line up neatly.

9) Adoption papers or guardianship orders (where relevant)

When a child is adopted, or when legal guardianship applies, the proof must show the legal relationship, not just day-to-day care. The documents that tend to work are court-issued adoption judgments, guardianship orders, and any updated civil status records reflecting the change.

This part of Dependent Proof for Student Spouse and Kids is sensitive to authenticity checks, so certified copies, correct translations, and a clear chain of legal authority matter more than volume.

10) Cohabitation proof pack: joint lease or rental agreement

A joint lease is one of the most direct cohabitation documents because it ties both names to the same address for a defined period. It’s stronger when it includes signatures, dates, landlord details, and the full property address.

For Dependent Proof for Student Spouse and Kids, leases work best when they’re supported by documents that show actual living activity at that address, like bills and bank statements.

11) Cohabitation proof pack: joint utility bills (address history)

Utility bills can show ongoing shared residence over time. Electricity, water, heating, internet, and municipal service bills tend to be more persuasive than mobile phone bills because the service address is fixed.

What usually makes bills “work” for Dependent Proof for Student Spouse and Kids is consistency, several months across the same address, with names spelled the same way each time. If only one partner is named, pairing with a lease and bank statements can still create a clear story.

Utility types that usually help

• Electricity
• Gas or heating
• Water
• Internet (fixed line)
• Municipal services (where issued)

12) Cohabitation proof pack: joint bank account statements

Joint bank statements can show a shared financial life, which supports cohabitation and relationship stability. They’re often most convincing when they show both names on the account and regular household activity, not one dormant account created recently.

For Dependent Proof for Student Spouse and Kids, statements should be readable and consistent with the address used elsewhere in the file. If privacy is a concern, many applicants mask transaction descriptions while keeping names, dates, and balances visible, but acceptance depends on the authority’s rules.

Translation and authentication that prevents rejections

Translation issues cause avoidable refusals, even when the underlying Dependent Proof for Student Spouse and Kids documents are correct. Certified translations usually need the translator’s stamp or statement, and some authorities expect a specific format (translator details, date, signature, and confirmation of accuracy).

Authentication is the other common barrier. Depending on the issuing country and the receiving authority, an apostille (for Hague Convention countries) or legalisation via consular channels may be required. The goal is simple: the receiving office must be able to trust the document’s origin without guessing.

Common mistakes that weaken Dependent Proof for Student Spouse and Kids

• Submitting short-form certificates that don’t list parents, then getting asked for a long form later.
• Name mismatches across passport, certificate, and translation (spacing, spelling, accents).
• Old scans that cut off stamps, signatures, or registration numbers.
• Providing one cohabitation document instead of a timed set that shows continuity.
• Using screenshots instead of official PDFs or printed statements from the issuer.
• Missing legalisation or apostille when the document is from outside the expected recognition system.
• Uploading photos as “proof” without linking them to an actual dated event document.
• Mixing addresses across documents without explaining a move or change in residence.
