German Citizenship by Descent: The Complete Guide

Who qualifies, how the routes work, and how to find the records — a free, plain-English guide for anyone with German ancestry.

If you have a German parent, grandparent or further ancestor — including an ancestor persecuted between 1933 and 1945 — you may be able to claim or restore German citizenship. Whether you qualify depends on who the ancestor was, the dates, and the law that applied at the time. This guide maps every route so you can see where you fit.

Who qualifies for German citizenship by descent?

In broad terms, anyone with a documented line to a German ancestor may have a claim — but the detail matters. Ordinary descent requires citizenship to have passed unbroken from the German ancestor down to you. Restoration routes reopen historic injustices and can reach much further back. The only way to know is to trace the line and the dates.

The two paths: descent and restoration

Descent covers an unbroken chain of citizenship from a German parent or grandparent. Restoration covers people stripped of citizenship through Nazi-era persecution (Article 116(2)) and those excluded by historic gender-discriminatory rules (StAG §5), plus a wider declaration route for the persecuted (StAG §15). Most families fit one of these — and the routes sometimes overlap.

Why dates and borders matter

German nationality law changed repeatedly, and the law in force when your ancestor was born, married or emigrated is the law that applies to them. Borders moved too — in 1871, 1919, 1938 and 1945 — so a town that is Polish, French or Czech today may have been German when the record was created. Dates and jurisdiction, not today’s map, decide where the proof lives.

What the process involves

In practice: identify your route, trace the line, locate and obtain the civil records that prove it, arrange any certified copies or translations, and submit to the Bundesverwaltungsamt or a German mission abroad. The application decision is usually the quicker part; assembling the evidence is where the work is.

Your questions answered

Can I get German citizenship if only one grandparent was German?

Possibly — if citizenship passed unbroken down that line, or if a restoration route applies. The dates and the law in force decide it.

Is there a deadline to apply?

The restoration route under Article 116(2) has no deadline. The StAG §5 declaration route is time-limited (currently to 19 August 2031).

Does it cost anything to check whether I qualify?

No — this guide is free. Working out your route only takes tracing your line and the dates.
