Clarify when and how citizenship was lost
First establish prior German citizenship and the precise loss date. Collect old German passports, foreign naturalization and release documents, and residence information. For people habitually resident abroad, the Federal Office of Administration explains section 13 StAG; section 14 concerns other special applications from abroad. Family history alone is not proof.

Only the competent authorities can examine documents, exceptions, security checks and statutory requirements in an individual case and make the official decision.
