What Is German Citizenship by Descent? The Jus Sanguinis Principle
German citizenship is governed by the principle of jus sanguinis — "right of blood" — under §4(1) Staatsangehörigkeitsgesetz (StAG). Citizenship passes automatically to a child born to at least one German-citizen parent, regardless of where in the world the birth occurs. The foundational statute for all descent claims is the Reichs- und Staatsangehörigkeitsgesetz of 1913 (RuStAG 1913), which unified German citizenship law across all German states. The Staatsangehörigkeitsausweis (citizenship determination certificate) issued by a Staatsangehörigkeitsbehörde is a formal confirmation of a pre-existing citizenship right, not a grant of new citizenship. Since 27 June 2024, Germany permits multiple citizenship — descent claimants may retain their existing US, UK, Israeli, or other passport.
- Legal basis: §4(1) StAG — citizenship transmits through a German-citizen parent at birth
- Foundational statute: RuStAG 1913 — governs all descent chains traced to pre-1914 ancestors
- Birthplace is irrelevant — a child born in New York to a German parent is automatically German
- Jus sanguinis ≠ jus soli — being born on German soil does not alone confer citizenship
- Since 27 June 2024 (StARModG, BGBl. 2024 I Nr. 43): multiple citizenship permitted — no renunciation required
Who Qualifies — The Generational Eligibility Chain
There is no fixed generational limit on citizenship by descent — what matters is the integrity of the transmission chain from the German ancestor to the applicant. Each link in the chain must have actually acquired and transmitted German citizenship. Your parent must have been a German citizen at the time of your birth. Your grandparent must have transmitted citizenship to your parent. A break in any link — through renunciation, foreign naturalisation under the old §25 StAG, or an out-of-wedlock birth rule before 1975 — can terminate the chain. Anyone tracing citizenship through a great-grandparent must assess each generation individually, paying particular attention to the §4(4) StAG registration trap for the third generation born abroad.
- Parent is or was German at time of birth: citizenship automatically acquired under §4(1) StAG
- Grandparent route: valid only if parent also acquired citizenship (chain must be unbroken)
- Great-grandparent and earlier: each generation requires individual assessment — no automatic limit
- RuStAG 1913 cut-off: for ancestors who emigrated before 1914, state-level citizenship (Prussia, Bavaria, etc.) governs eligibility
- Pre-1871 ancestry: German state-level citizenship rules apply — complex genealogical analysis required
- §4(4) StAG registration trap: children born abroad after 31 December 1999 whose German parent was also born abroad must be registered at a German consulate within one year or citizenship transmission is lost
Key Cut-Off Dates — How German Law Changed Over Time
The rules of citizenship transmission changed fundamentally at several points in the 20th century. German women who married non-German men between 1914 and 1953 automatically lost their citizenship — their descendants may need to pursue restoration under Article 116(2) GG rather than a standard §4 StAG descent claim. Children born out of wedlock before 1 July 1993 to a German father did not automatically receive citizenship under the old BGB §1717 legitimacy rules. Children born to a German mother before 1 January 1975 also did not automatically acquire citizenship in all cases. Understanding which historical rule applies to your specific ancestor and birth date is essential before filing any application.
| Period | Rule | Impact on Descent Chain |
|---|---|---|
| Before 1 January 1914 | RuStAG 1913 not yet in force | State-level citizenship (Prussia, Bavaria etc.) governs |
| 1914–1953 | Women lost citizenship upon marrying non-German men | Descendants of these women may need §116 GG restoration |
| Before 1 July 1975 | German mother: not automatic transmission in all cases | Some children of German mothers pre-1975 may lack citizenship |
| Before 1 July 1993 | German father out of wedlock: no automatic transmission | Old §1717 BGB legitimacy rules block paternal chain |
| Post 31 December 1999 | §4(4) StAG: 3rd-generation abroad birth requires registration | Failure to register within 1 year breaks chain permanently |
| 27 June 2024 | StARModG reform: multiple citizenship permitted | Descent claimants may keep existing passports |
Nazi-Era Deprivation — §116 GG and §15 StAG: Two Distinct Pathways
Germany provides two separate legal routes for persons whose ancestors were stripped of German citizenship between 30 January 1933 and 8 May 1945. Article 116(2) Grundgesetz (GG) is a constitutional restoration right for the former nationals themselves and their descendants — it requires only a declaration, not an application, and there is no language test. §15 StAG is the statutory application route for descendants of those persecuted on political, racial (including Jewish descent), or religious grounds. Both routes require no renunciation of existing nationality and no minimum residence in Germany. Applications are processed by the Bundesverwaltungsamt (BVA) in Cologne for persons living abroad, with current processing times of 12–24 months.
KEY DISTINCTION: Article 116(2) GG applies to former German nationals who were themselves directly stripped of citizenship 1933–1945. §15 StAG applies to their descendants born after the deprivation. The 2019 and 2024 amendments to §15 StAG significantly broadened eligibility — descendants of persecuted mothers and grandchildren of persecution victims are now included. If you are unsure which pathway applies, German Company Formation offers a free preliminary eligibility assessment.
What Breaks the Citizenship Chain — Eligibility Disqualifiers
A descent claim fails if any link in the transmission chain was broken by a qualifying legal event. The most common disqualifier is voluntary foreign naturalisation by an intermediate ancestor under the old §25 StAG — before the 2024 reform, naturalising as a citizen of another country automatically terminated German citizenship. This break is not cured by the 2024 StARModG reform, which operates prospectively only. Other disqualifiers include voluntary renunciation (Verzicht) of German citizenship by the ancestor, and out-of-wedlock birth rules that prevented paternal transmission before 1993. Importantly, ethnic German origin (Volkszugehörigkeit) does not equal German citizenship — the Spätaussiedler route under BVFG §6 is a separate pathway with its own language requirements and must not be confused with the descent route.
- Voluntary foreign naturalisation under old §25 StAG: German citizenship automatically lost — breaks the chain for all descendants
- Voluntary renunciation (Verzicht): same effect as foreign naturalisation — the chain is broken
- §4(4) StAG registration failure: child born abroad post-1999 to German parent also born abroad who was not registered within 1 year
- Out-of-wedlock birth to German father before 1 July 1993: no automatic citizenship under old §1717 BGB
- Ethnic German descent ≠ German citizenship: Volkszugehörigkeit and Staatsangehörigkeit are different legal concepts
- Note: the 2024 StARModG reform does NOT retroactively restore citizenship lost under old §25 StAG — §13 StAG re-naturalisation is the remedy
Documents Required — Complete Checklist for a Descent Application
The application for a Staatsangehörigkeitsausweis or a §15 StAG restoration requires documentary proof of every link in the ancestry chain. All foreign documents must be authenticated with an apostille under the Hague Convention and accompanied by a certified German translation from a sworn translator (beeidigter Übersetzer). Plain photocopies and unofficial translations are not accepted. The primary sources for German civil records are the Standesamt (local civil registry) of the relevant birth or marriage city, the Bundesarchiv in Koblenz and Berlin-Lichterfelde for wartime records, and digital archives such as Arcinsys and Matricula for church records (Kirchenbücher). US-based researchers should additionally consult the Family History Library (LDS Church), Ancestry.de, and the US National Archives (NARA) for emigration records.
| Document | Purpose | Primary Source |
|---|---|---|
| German ancestor's birth certificate (Geburtsurkunde) | Proves German birth and citizenship status | Standesamt of birth city; church records for pre-civil registry births |
| German ancestor's passport or Staatsangehörigkeitsausweis | Confirms citizenship was held | German archives; BVA records; Bundesarchiv |
| Marriage certificates (Heiratsurkunde) for each married couple in the chain | Links each generation to the next | Standesamt; church records; apostilled foreign registry |
| Naturalisation records (or confirmation of non-naturalisation) | Proves chain was not broken by foreign naturalisation | US NARA; Ellis Island records; Ancestry.de; home-country civil registry |
| Applicant's birth certificate | Links applicant to the German parent | Own country civil registry + apostille + sworn German translation |
| Applicant's current passport | Identity verification | Own passport authority |
Application Process — Where to File and How Long It Takes
Applicants residing outside Germany file their claim at the German embassy or consulate in their country of residence. The consulate forwards the application to the competent Staatsangehörigkeitsbehörde of the relevant German Bundesland, or to the Bundesverwaltungsamt (BVA) in Cologne for §15 StAG restoration claims and cases involving former residents of the eastern territories. The BVA issues a Feststellungsbescheid — a formal administrative determination confirming German citizenship status. The §38 StAG fee for a citizenship determination is €51; §15 StAG restoration is typically fee-waived for persecution victims. Applicants residing in Germany file directly with the Staatsangehörigkeitsbehörde of their city.
- Outside Germany: file at German embassy or consulate in your country of residence
- Germany residents: file at local Staatsangehörigkeitsbehörde (e.g. Düsseldorf: Stadthaus, Burgplatz 1)
- §15 StAG restoration abroad: BVA Cologne processes — bva.bund.de
- Fee: €51 (§38 StAG) for descent determination; §15 restoration typically fee-waived
- Processing times: 6–18 months for §4 StAG descent determination; 12–24 months for §15 StAG restoration (BVA)
- After Feststellungsbescheid: apply for German Reisepass at consulate (4–8 weeks additional)
The 2024 Dual Citizenship Reform — Keeping Your Existing Passport
The Gesetz zur Modernisierung des Staatsangehörigkeitsrechts (StARModG), effective 27 June 2024 (BGBl. 2024 I Nr. 43), fundamentally changed Germany's approach to multiple citizenship. Descent claimants were never required to renounce — citizenship by descent under §4 StAG or restoration under §15 StAG was always treated as an inherited or restored right, not a new grant requiring renunciation. The 2024 reform now aligns the naturalisation track with the descent track: no applicant of any nationality need surrender their existing passport. US citizens who obtain German citizenship by descent retain their US passport under US law (INA §349 — naturalisation alone without intent to relinquish does not cause loss of US citizenship per Afroyim v. Rusk).
US citizens: claiming German citizenship by descent does NOT trigger loss of US citizenship. Under INA §349 and the US Supreme Court's Afroyim v. Rusk (1967) ruling, US citizenship can only be lost through an act performed voluntarily with the intent to relinquish it. Confirming a descent-based citizenship right — one you held since birth — does not constitute such intent. You will hold both passports simultaneously. UK, Israeli, Australian, and most other passport holders are similarly unaffected.

Fees and Realistic Timelines
The statutory fee for a citizenship determination (Staatsangehörigkeitsausweis) is €51 under §38 StAG. §15 StAG restoration is typically fee-waived for persecution victims. Additional costs depend on the complexity of the lineage chain: document translations run €60–€120 per document, apostilles €30–€80 per document depending on country, and archive requests vary by institution. Total out-of-pocket for a straightforward single-generation §4 StAG claim is typically €400–€900 excluding legal fees. Multi-generation or §15 StAG claims with complex archive research typically cost €2,500–€8,000 in specialist legal fees. We provide a fixed-fee or capped-cost engagement agreement at the outset.
- Staatsangehörigkeitsausweis fee: €51 (§38 StAG)
- §15 StAG restoration: typically fee-waived for persecution victims
- Sworn translation per document: €60–€120

Frequently Asked Questions
Can I get German citizenship if my great-grandparents were German?
Possibly — but it depends on whether the citizenship chain is unbroken in every generation between your great-grandparent and yourself. Each intermediate ancestor must have acquired German citizenship and transmitted it without renunciation, foreign naturalisation under the old §25 StAG, or another chain-breaking event. The §4(4) StAG registration requirement (for children born abroad after 1999 whose German parent was also born abroad) can also break the chain. Cases involving great-grandparent lineage require specialist assessment — German Company Formation offers a free preliminary eligibility review.
How many generations back can I claim German citizenship?
There is no fixed generational limit under German law. The decisive question is whether the citizenship chain from the German ancestor to you is unbroken in every link. A great-great-grandparent who emigrated from Bavaria in 1885, whose children and grandchildren all held German citizenship without renouncing it, can in principle transmit citizenship to a current-generation claimant. What matters is chain integrity — not generation count. The RuStAG 1913 governs claims traced to ancestors who emigrated before 1 January 1914.
Do I need to speak German to claim citizenship by descent?
No. German language proficiency is not required for a citizenship-by-descent claim under §4 StAG or a §15 StAG / §116 GG restoration claim. Language requirements apply only to naturalisation under §10 StAG. Descent claimants may have no German language skills at all and the citizenship right is entirely unaffected.
Can I keep my US or UK passport if I get German citizenship by descent?
Yes. German citizenship by descent does not require renunciation of your existing nationality. Since 27 June 2024, Germany broadly permits multiple citizenship for all applicants. For US citizens, US law also does not cause citizenship loss upon confirming a descent-based German citizenship — under INA §349 and Afroyim v. Rusk (1967), only a voluntary act with intent to relinquish can terminate US citizenship. Confirming an inherited right does not constitute such intent.
What is the difference between Article 116 GG and §15 StAG?
Article 116(2) GG is a constitutional restoration right for former German nationals who were themselves directly stripped of citizenship between 1933 and 1945. It requires only a declaration (no formal application) and is filed at BVA Cologne or a German consulate. §15 StAG is the statutory application route for descendants of persecution victims — for persons who were born after the deprivation and thus never held German citizenship themselves. Both routes require no renunciation of existing nationality and no language test.
How long does the citizenship-by-descent application take?
§4 StAG descent determinations typically take 6–18 months depending on the authority (German embassy → Staatsangehörigkeitsbehörde). §15 StAG restoration applications processed by the Bundesverwaltungsamt (BVA) in Cologne currently take 12–24 months due to high demand following the 2019 and 2024 amendments. A German passport is issued 4–8 weeks after the Feststellungsbescheid. The main delay in straightforward cases is assembling and apostilling the documentary chain.
What documents do I need for a citizenship-by-descent claim?
You need to document every link in the ancestry chain: the German ancestor's birth certificate and proof of German citizenship (passport, Staatsangehörigkeitsausweis, or naturalisation records); marriage certificates for each married couple in the chain; evidence that no intermediate ancestor renounced or lost citizenship; and the applicant's own birth certificate. All foreign documents require an apostille and sworn German translation. Key sources: Standesamt, Bundesarchiv, church records, US NARA and Family History Library.
What if my German ancestor renounced or lost their citizenship?
Voluntary renunciation or loss of citizenship under old §25 StAG (foreign naturalisation) breaks the descent chain permanently for all subsequent descendants — the 2024 StARModG reform does not retroactively cure this. However, if citizenship was lost due to Nazi-era persecution (§15 StAG) or gender discrimination (women who married non-German men 1914–1953 under §116 GG), restoration routes remain available regardless of the break in the standard descent chain. We assess which pathway applies in your specific case.
Can my children also get German citizenship once I obtain it?
Yes. Once your German citizenship is confirmed by Feststellungsbescheid, your children who are minors at that time can also apply for citizenship determination. More importantly, any children born to you after your citizenship is confirmed will acquire German citizenship automatically at birth under §4(1) StAG — regardless of where they are born. You will also be able to transmit German citizenship to future children, and they may hold it simultaneously with any other nationality.
Where do I apply if I live outside Germany?
You apply at the German embassy or consulate in your country of residence. The consulate collects your application package and forwards it to the competent Staatsangehörigkeitsbehörde or to the Bundesverwaltungsamt (BVA) in Cologne for §15 StAG cases. The BVA is the competent federal authority for overseas applicants in §116 GG declaration cases and for persons with ancestry from the former eastern German territories. All communication with the German authority is routed through the consulate.
Is there a fee for the citizenship determination?
Yes — €51 per applicant under §38 StAG for a standard Staatsangehörigkeitsausweis (citizenship determination certificate). §15 StAG restoration is typically fee-waived for persecution victims. Additional costs include consulate administrative fees (€30–€60), sworn German translations (€60–€120 per document), and apostilles (€30–€80 per document). These are the administrative costs only — legal representation by our firm is quoted separately on a fixed-fee basis.
