Germany Citizenship — Adoption (§ 6 StAG)

Summary

Section 6 of the German Nationality Act (§ 6 Staatsangehörigkeitsgesetz, StAG) provides that a foreign child adopted by a German citizen acquires German citizenship automatically on the date the adoption takes effect under German law, provided the child was under 18 at the time the adoption application was filed. The citizenship attaches by operation of law — there is no separate naturalization application, no language test, and no residency requirement.

The adoption must be legally valid in Germany. A domestic adoption decreed by a German family court qualifies directly. A foreign adoption needs to be recognised under German law — typically via a formal recognition procedure (Anerkennung) conducted by a German family court under the Adoption Effects Act (Adoptionswirkungsgesetz, AdWirkG). Hague Convention intercountry adoptions are the most common qualifying foreign route, and there is a streamlined recognition path for Convention adoptions.

Under § 6, acquisition extends to the adoptee's own descendants who were minors at the time of the adoption order, mirroring the way natural-born German citizenship passes. Since the citizenship attaches on the effective date of the adoption, people adopted by German citizens may already be German without ever having held a passport — the practical step is obtaining a certificate of citizenship (Staatsangehörigkeitsausweis) or a German passport to evidence it.

Since the dual citizenship reform of 27 June 2024, there is no longer a general obligation to renounce a prior nationality when acquiring German citizenship, so U.S. and other foreign adoptees confirmed under § 6 keep their original citizenship.

Eligibility

You automatically became a German citizen under § 6 StAG if all of the following were true:

• You were adopted as a minor — the application for adoption was filed before you turned 18.
• At least one adoptive parent was a German citizen at the time the adoption took effect.
• The adoption is legally effective in Germany, via one of:
  • A German family court adoption order; or
  • A Hague Convention intercountry adoption (automatic recognition in Germany); or
  • A foreign adoption recognised under the Adoptionswirkungsgesetz after a German family-court recognition (Anerkennung) procedure.
• The adoption has not subsequently been annulled.

Out of scope:

• Adoptions completed when the adoptee was 18 or older (adult adoptions) do not transmit citizenship under § 6 — they require a separate route, and adult adoption under German law is rare.
• Foreign adoptions that have not been recognised or converted in Germany — even if valid in the country of origin — do not trigger § 6. You need a German recognition step first.

What This Route Allows

This route can help confirm or document citizenship in Germany when the citizenship-creating facts named above are proven. For many people in this category, the main work is evidence: civil records, family-link records, prior citizenship records, and any registration or restoration paperwork needed to show the claim.

What This Route Is Not

This is not a shortcut around documentation. Even when the citizenship claim is based on a right, you still need records that prove each required fact and family link.

Next Steps

1. Obtain the adoption decree — a German court order, Hague Convention Article 23 certificate, or a foreign adoption decree with an apostille and certified translation, depending on where the adoption occurred.
2. If the adoption was foreign and non-Hague, apply for recognition (Anerkennung) at the German family court with jurisdiction over your habitual residence or the adopter's residence. The court issues a decision on the effects of the foreign adoption under German law (Anerkennungsbeschluss).
3. Evidence the adoptive parent's German citizenship on the date the adoption took effect — German passport, Personalausweis, or Staatsangehörigkeitsausweis valid at that date.
4. Apply for a Staatsangehörigkeitsausweis (certificate of German citizenship) at the Bundesverwaltungsamt (BVA) in Cologne — or, from abroad, at the German consulate with jurisdiction over your country of residence. This is the formal proof of German citizenship and the usual starting point when no German documents have previously been held.
5. Apply for a German passport at the same consulate once the Staatsangehörigkeitsausweis issues, or in parallel if the consulate accepts the supporting documents directly.
6. Document the chain for minor children. If you have minor children of your own, § 6 transmits citizenship to them as of the adoption date only if they were minors at that time; adult children are not covered.
7. Consult a qualified German immigration attorney if the adoption is foreign and non-Hague, if the adoptive parent's citizenship at the relevant date is contested, or if you have previously received inconsistent guidance from a consulate.
