Which documents are needed for German citizenship? [2026 English Guide]

Key Takeaways

• The Federal Office of Administration sorts documents into two load-bearing groups: proof of your descent and identity, and proof of your ancestor’s German citizenship or legal status.
• Documents not in German or English need a certified translation. Foreign birth and marriage certificates may also need a Hague Apostille or legalization, depending on the issuing country.
• Submit certified copies instead of originals to protect your case if something is lost in the mail. A single missing or unusual document does not automatically end your case, since the Federal Office of Administration will ask directly if it needs something more.

How can you get German citizenship?

You can get German citizenship in one of six ways.

1. Naturalization
2. Descent
3. Adoption
4. Birth
5. Marriage
6. Declaration

This guide walks through which documents actually matter once you know your route, and what to do when the “obvious” document is missing, unusual, or written in a language the Federal Office of Administration doesn’t process directly. It focuses on the declaration route under Section 5 and the restitution routes under Section 15 and Article 116(2), since these cases most often involve documents from decades ago. Restitution routes cover people who lost German citizenship, or could never acquire it, because of Nazi-era persecution, along with their descendants.

See our guide on citizenship by declaration or restoring lost or denied citizenship for eligibility rules and the full document checklist for each route.

Which documents do you actually need?

The Federal Office of Administration groups documents into three categories:

• proof of your descent and identity
• proof of your ancestor’s German citizenship or legal status
• supplementary documents

The first two groups mentioned are truly load-bearing. That means the case cannot proceed without it. It uses almost the same wording across its declaration, restitution, and citizenship-confirmation instructions.  This applies whether you are filing under declaration or restitution.

The first group proves your descent and identity. 

• Birth certificate or certificate of descent
• Marriage certificate, where relevant to the chain of descent
• Foreign personal identity documents, such as a passport or national ID card

The second group proves your ancestor’s German citizenship or legal status as German. The Federal Office of Administration’s own list is broader than most applicants expect.

• German identity documents, including an old passport or identity card
• A naturalization certificate
• A certificate of acquiring German citizenship by declaration or option
• A Spätaussiedler certificate, expellee card, or registration certificate for ethnic German resettlers
• A refugee document
• An extract from the German residents’ register
• Documents establishing membership in a group covered by a collective naturalization

A persecution or displacement record does not need a birth certificate standing behind it to matter. It can independently establish an ancestor’s citizenship or legal status.

The third group is supplementary. The Federal Office of Administration calls these “further helpful documents, if applicable.”

• Proof of holding or losing another citizenship
• Name-change certificates
• Custody documents for applicants under 16

The Federal Office of Administration also asks Section 5 declarants aged 14 and over for a current police clearance certificate from their country of residence, submitted as an original. This requirement sits outside the descent-and-identity and citizenship-status groups. It is its own category, unique to the declaration route.

What if a document isn’t in German or English?

You should still submit the document. Hebrew, Russian, and other non-German, non-English documents come up often in restitution and Article 116(2) cases, since the underlying persecution and displacement records were rarely created in German.

1. Submit the original document in its original language.
2. Attach a certified translation into German, done by a sworn translator. This applies across German citizenship procedures generally, not only this one. You can use Translayte* to book a sworn translator.
3. Add a Hague Apostille or legalization for birth and marriage certificates issued outside Germany if your country of issue requires one. This depends on the issuing country and is not spelled out on every procedure page, so confirm with your nearest German mission which applies to your document.

Do you need a death certificate for an ancestor in the middle of your chain?

You do not need a death certificate for an ancestor in the middle of your chain by default. It is not on the Federal Office of Administration’s list of typically required documents, since it is neither a descent-and-identity document nor a citizenship-status document.

It only becomes relevant if it resolves a specific factual question in your case, such as:

• Confirming your ancestor’s citizenship had not already been lost through some other event before it passed to the next generation
• Confirming the timing of a death relative to a legal cutoff date

Don’t submit it unless you know it answers a specific gap in your chain. If the Federal Office of Administration needs it, it will ask. Submitting it unprompted does not speed up your case, since a reviewer still has to work out what fact it is meant to establish before it does anything.

Can a restitution document replace a missing birth certificate?

It depends on which fact the birth certificate was supposed to prove.

• You do not need a birth certificate if a restitution or persecution document already establishes your ancestor’s own German citizenship. The Federal Office of Administration’s own list already treats these as citizenship-status evidence in their own right, in the same load-bearing group described above.
• You still need a document that names both generations, such as a birth certificate, a certificate of descent, or a family register entry, if you are proving descent from that ancestor, meaning the parent-child link itself. A restitution document does not cover that gap by itself.

NOTE: State what your substitute document proves, in writing. For example: “This restitution certificate confirms my grandfather’s German citizenship as of 1938.” This isn’t a formal requirement, but it gives the reviewer less to guess at than the document alone.

If records were destroyed or scattered across several generations, consider consulting an immigration lawyer before you submit. You can consult an immigration lawyer we recommend here.

What if your documents get lost before your case is decided?

A missing document is usually not the end of your case. Two things reduce the risk before you even mail anything:

• Submit certified copies rather than originals, wherever the instructions allow it. The Federal Office of Administration prefers certified copies for most documents. They only ask for originals in specific cases, such as the police clearance certificate. A certified copy is easier to replace than an original if it goes missing.
• Keep your own scanned copy of everything before you mail it. This is not an official requirement. It is what limits the damage if a package goes missing.

If something does go missing after mailing, the Federal Office of Administration contacts you if it still needs that piece of evidence to decide your case. Whether you can still file with one document missing depends on how central that document is to your case. Contact the Federal Office of Administration directly if you are not sure whether what you have left is enough. It can tell you whether to file now or wait for the missing piece.

If a German civil registry document itself needs replacing, such as a birth or marriage certificate held by a Standesamt, request a new certified copy directly from the registry office in the town where the event took place. Germany has no central civil registry, so the request has to go to that specific local office. Our guide on German historical civil and residence records covers how to track down the right office.
