Your great-grandmother was German. Perhaps you have her old passport, perhaps an immigration list, perhaps just a family story about emigrating from Hamburg in the 1920s. And now you're wondering: is that enough to get German citizenship?<\/p>\n
The answer isn't yes or no \u2013 rather: It depends. And it doesn't depend on whether your great-grandmother was German. That's the start of the test, not the result. What matters is what happened in every single generation between her and you. German citizenship is passed down from parent to child \u2013 but only if the chain hasn't been broken at any point.<\/p>\n
And here it becomes surprising for many families: Even if the chain is broken at some point, there are new ways to repair it since 2021 and 2024. These ways exist because previous law treated mothers and fathers unequally \u2013 and the legislator wants to correct this unequal treatment retroactively.<\/p>\n
This article is for general guidance only and does not replace individual legal advice. Whether you are entitled to German citizenship depends on the specific circumstances of your family history. For an assessment of your individual case, please contact an attorney specialising in citizenship law.<\/i><\/p>\n Germany follows the principle of ius sanguinis \u2013 \u201eright of blood\u201c. Unlike, for example, the USA, where birth on American soil establishes citizenship, German law primarily links citizenship to parentage. If one parent was a German national at the time of your birth, you generally are too \u2013 regardless of where in the world you were born.<\/p>\n This principle knows no generational limit. If your great-grandmother was German and passed on citizenship to your grandfather, who passed it on to your father, who passed it on to you, then you may already be a German citizen \u2013 even if no one in your family has held a German passport for generations.<\/p>\n However, there is one crucial reservation: nationality does not skip a generation. If the chain was broken at any point between your great-grandmother and you, you cannot derive nationality from the earlier ancestor. To assess whether your chain is intact, you must answer three questions at each generational step.<\/p>\n For each generation between your German ancestor and yourself, the law asks:<\/p>\n For a great-grandparent claim, you must answer these three questions three times \u2013 once for each generational step. This is what fundamentally makes these cases more complex than claims that only go through parents or grandparents.<\/p>\n Your great-grandfather was born in Germany in 1900. He emigrated to the USA in 1925 but never became an American citizen. Your grandfather was born in New York in 1930 \u2013 as his father was still German, he acquired German citizenship by birth. Your grandfather was naturalised in the USA in 1955. However, your father was already born in 1948 \u2013 therefore, before his grandfather's naturalisation \u2013 and also acquired German citizenship at birth.<\/p>\n Result: <\/b>You are highly likely a German national. The chain of descent is intact. Your great-grandfather never lost his nationality. Your grandfather was still German at the time of your father's birth. And your father was German at the time of your birth. The fact that your grandfather later became an American citizen does not retroactively change this.<\/p>\n The same family, but with a change: the great-grandfather became an American citizen in 1928 \u2013 two years before your grandfather was born in 1930.<\/p>\n Result: <\/b>Your grandfather did not acquire German nationality at birth because his father was no longer German at that time. The chain broke at the first generational step. By the regular rules of descent, neither your father nor you can derive nationality from your great-grandfather.<\/p>\n This is the constellation under which most families fail. The great-grandfather was undoubtedly German \u2013 born in Germany, German-speaking, German in his self-perception. But legally, nationality ended the moment he adopted another. For everyone born after that, the legal chain stops there.<\/p>\n Your great-grandmother was born in Germany in 1910. She emigrated to the USA and married an American man in 1935. She never became naturalised and remained a German citizen all her life. Your grandmother was born in 1938 \u2013 legitimately, to a German mother and a non-German father.<\/p>\n Under the law applicable at the time, nationality was exclusively passed down through the father upon birth within marriage. Although her mother was German, your grandmother did not acquire nationality at birth. The chain is broken \u2013 not because anyone renounced citizenship, but because the law treated women and men unequally.<\/p>\n But this is exactly where it gets interesting: <\/b>The 2021 reform introduced a right of declaration, allowing your grandmother \u2013 or you as her descendant \u2013 to acquire German citizenship through a simple declaration. This is the regulation \u00a7 5 of the Nationality Act<\/a>, which specifically remedies the consequences of gender-discriminatory laws. And it applies not only to the directly affected child, but to all descendants in the line.<\/p>\n Many great-grandparent claims can actually be realised here. Before 1975, a married German woman could not pass on her nationality to her children if the father was a foreigner. Before 1st April 1953, it was even more restrictive: a German woman who married a foreigner automatically lost her German nationality.<\/p>\n The affected groups are:<\/p>\n If you fall into one of these categories, you can acquire German citizenship by a simple declaration to the Federal Office of Administration (BVA). No language test. No naturalisation test. No obligation to give up your previous citizenship. No residency in Germany required.<\/p>\n The crucial detail: <\/b>This right of explanation expires on 19 August 2031. After that, it will be permanently extinguished. And because obtaining the necessary birth and marriage certificates \u2013 particularly from foreign archives \u2013 can take years, the actual deadline is significantly earlier than it initially appears.<\/p>\n Acquisition of citizenship by declaration under Section 5 of the Nationality Act (StAG) covers gender-based unequal treatment. However, there are other reasons why the chain between your great-grandparent and you may be broken. Depending on the cause, different routes are available.<\/p>\n <\/p>\n<\/span>How the principle of ancestry works<\/span><\/h2>\n
