German citizenship by descent is not a single application route. Some people already acquired citizenship automatically at birth and need a certificate to prove it. Others may qualify for a declaration because historic law discriminated on the basis of sex, or for restoration because citizenship was lost through Nazi persecution.
The correct route can only be chosen after a dated family timeline is tested against the law in force at each event.
Identify the procedure before completing a form
Determination is used where a person says they are already German and needs the competent authority to establish that status. Declaration under Section 5 is a ten-year corrective route for certain people affected by earlier sex-discriminatory transmission rules and their descendants. Restoration routes address defined cases connected with Nazi persecution. Discretionary naturalisation is separate and should not be described as automatic descent.
For applicants habitually resident outside Germany, the Federal Office of Administration (Bundesverwaltungsamt, BVA) is generally the competent citizenship authority. A German mission can provide forms and transmit an application, but it does not replace the BVA’s substantive decision.
Prove the chain at every generation
Write down the citizenship, birth, marriage, migration and naturalisation facts for each generation. Historic German territory and status can be complex; an ancestor’s German-language name or place of birth is not enough.
Key questions include:
- Was the ancestor a German citizen, and what document proves it?
- Was the relevant child born in or outside marriage under the terminology and law of that period?
- Which parent could transmit citizenship on that birth date?
- Did naturalisation abroad, release, renunciation or another event occur before the next birth?
- Was any registration deadline triggered for a later generation born abroad?
Do not apply today’s rules retrospectively. The law at the relevant time controls the analysis.
Section 5 declarations have a deadline
Section 5 of the Nationality Act created a declaration route for defined groups who did not acquire German citizenship at birth because of former sex-discriminatory provisions, as well as their descendants. It concerns births after the Basic Law entered into force on 23 May 1949 and categories described in the official BVA guidance.
The declaration must reach the competent authority by 19 August 2031. That deadline is not a reason to submit an incomplete or ineligible case, but it makes early record collection sensible. Check the current BVA form to confirm that the applicant fits one of the specified groups; having a German grandmother is not, by itself, the legal test.
Children born abroad and the registration rule
A special rule can affect a child born abroad to a German parent who was also born abroad after 31 December 1999 and ordinarily lives abroad. In relevant cases, the child may not acquire citizenship automatically unless the birth is registered within one year, subject to the statutory conditions and exceptions.
This “generation cut” is often misunderstood. Families with a German parent born abroad after 1999 should obtain case-specific guidance before the child’s first birthday rather than relying on a later descent application.
Prepare a coherent evidence file
The BVA may request civil-status certificates covering the applicant and each connecting generation, proof of German citizenship, naturalisation or non-naturalisation evidence, identity documents and records explaining name changes. Foreign documents may require certified copies and German translations under the official instructions.
Create a one-page chronology and label every exhibit. If a record is unavailable, document the archive search and ask the authority what alternative evidence it accepts. Never purchase a “guaranteed passport” service based solely on a surname search.
German citizenship by descent FAQ
Is everyone with a German grandparent a German citizen?
No. Citizenship must have been held and transmitted through each relevant generation, or the applicant must qualify under a specific declaration or restoration provision.
What is the deadline for a Section 5 declaration?
The declaration must reach the competent authority no later than 19 August 2031 under the current official guidance.
Does Germany allow dual citizenship?
German law changed in 2024 to permit multiple citizenship more broadly, but the applicant must also consider the law of every other citizenship held, including Nigerian law.
Can the German Embassy decide my citizenship case?
For people residing abroad, the BVA is generally the deciding authority. The mission can advise on procedure, certify documents where authorised and forward files.
How long will a determination take?
Processing depends on route, workload and the quality of historical evidence. The BVA’s current service information is a better source than a commercial promise, and no intermediary can guarantee a decision date.
