Descendants of German Jews and Jews living in Germany

By Article 116 section 2 of the German Constitution (Basic Law), descendants of persons who were expatriated in the Nazi era (1933-1945) by laws that were enacted by the Nazis are entitled to reclaim their German citizenship. The German courts and authorities in the past decades excluded descendants of persecuted persons from this entitlement if by the time the descendants were born, they would have not have obtained German citizenship by the general citizenship regulations of that time. For example, children born before 1 April 1953 to persecuted German women who married a non-German were excluded from obtaining German citizenship. But in 2020 the German Federal Constitutional Court finally made it clear that this approval practise contradicts the German Constitution. Therefore, many applicants who were previously rejected, are now entitled to German citizenship based on the expatriation of their ancestors. In addition, in 2021, the German parliament passed an amendment to the German Nationality Act which grants many descendants of persecuted persons German citizenship. Especially those Non-Germans who were excluded from obtaining German citizenship between 1933 and 1945, and also former Germans who lost German citizenship by former regular laws influenced by their persecution. For example, descendants of all Jews who were residents in Germany before January 1933 and had to flee from Germany in the Nazi era can apply for German citizenship based on this regulation. But also, those former Germans that lost German citizenship until 1955 for example by applying for another citizenship. Further groups of persecuted persons and their descendants are eligible if the Nazis excluded them from special or collective naturalization regulations based on the persecution. If the claim is not based on the German Constitution (see above) the citizenship authority will request a record of good conduct from the country of residence to exclude severe criminal charges.

Regular naturalization for residents in Germany and / or spouses of German citizens

According to the current legal regulations regular naturalization is possible after 5 years of legal residence in Germany (if a number of additional requirements are fulfilled). Since an amendment of the German Nationality Act in June 2024 it is no longer necessary to give up the previous citizenship when obtaining German citizenship. But the legal regulations in some other countries still do not allow dual citizenship – obtaining German citizenship therefore can lead to the cancellation of the previous citizenship in some cases. We often help when problems occur as regards the required identity documents, proof of sufficient income, multiple citizenship or communication with the citizenship authorities in general.

Naturalization of former German citizens living abroad

In the past many German citizens have lost their citizenship since they obtained another citizenship without prior approval by the German government. Until dual citizenship was allowed in general in Germany in 2024, obtaining a non-EU citizenship without prior approval could lead to an automatic loss of German citizenship, even if the person was not aware of the according regulation. Thereforeformer citizens who were affected by this rule in the past need to apply for re-naturalization to get back their German citizenship. We can help with this often very difficult procedure of re-naturalization. Children of German citizens who did not obtain citizenship by birth.

Children of German citizens who did not obtain citizenship by birth

Children of German mothers and their non-German spouses did not obtain German citizenship by birth until 1975 in Germany. The same was true for children of German fathers who were not married to the non-German mother until mid 1993. As a result, children of German women and parents who were not married often could not get German citizenship in the past. After the German Constitutional Court had ruled that the according regulations most likely are discriminatory and contradict the German constitution, a right to obtain German citizenship by declaration for children of German citizens born after May 1949 was introduced in 2021 (valid for 10 years only!). We are happy to help with according applications.
