Background
Why does this special route exist?
Earlier German citizenship law did not always treat descent through a German mother and a German father equally. As a result, some children did not acquire German citizenship at birth despite having a German parent, or citizenship was affected by rules that are no longer in force today.
The present declaration procedure is intended to remedy certain historical disadvantages. It is not a general relaxation of the rules on naturalisation.
Eligibility
Who may acquire German citizenship by declaration?
Potential cases include persons born after 23 May 1949 who did not acquire German citizenship through a German parent because of the rules applicable at the time. Certain historical cases involving a German mother who lost citizenship before the birth of the child, as well as other former rules affecting descent, may also be relevant.
The legal position at the time of birth or of the historical event must therefore be reconstructed.
Descendants
Children, grandchildren and further descendants
The special route is not necessarily limited to the person who was directly affected. Descendants can also be covered. This means that the legal position of a mother, grandmother or an earlier ancestor may still be relevant to later generations.
A complete documentary chain of descent is normally required.
Procedure
Why this is not an ordinary naturalisation procedure
This route must be distinguished from ordinary naturalisation. If the statutory conditions are met, German citizenship is acquired by declaration. The authority subsequently issues documentary confirmation.
The date on which the declaration reaches the competent citizenship authority can be decisive for the time of acquisition.
Evidence
Which documents are typically important?
Relevant evidence may include old German passports or identity cards, citizenship certificates, naturalisation certificates, registration records and other official evidence of German citizenship.
Birth certificates, marriage certificates, divorce records, documents concerning paternity and, where applicable, adoption records may also be necessary. Foreign documents can raise additional questions concerning translations, authentication and proof of civil status.
Limitations
Which exclusion grounds may matter?
German ancestry alone does not automatically establish eligibility. It must also be examined whether German citizenship was later held and then renounced or lost, and whether other statutory exclusion grounds apply. Certain serious criminal convictions can also be relevant.
Deadline
Deadline: 19 August 2031
The special declaration route is time-limited. Under the current administrative guidance, the declaration must reach the competent authority no later than 19 August 2031.
Obtaining civil-status records across several generations and from different countries can take considerable time.
