Military ParadoxPolandlegal: The documented legal situation where Polish men aged 18–50 could not obtain a zwolnienie from Polish consulates because of military obligation.

Portaria 1403-A/2006Portugallegal: The Portuguese ministerial order that defines acceptable evidence for ligação efetiva (effective connection) in grandchild citizenship claims.

StaatsangehörigkeitsausweisDEdocument: The official certificate confirming German citizenship, issued by the BVA after a successful Feststellung application. Required before applying for a German passport.
StAG §25DElegal: The primary chain-breaker in German citizenship descent: a German citizen who voluntarily naturalized in a foreign country automatically lost German citizenship under this provision (in force since 1913).

Z

ZwolnieniePolandlegal: Formal release from Polish citizenship (zwolnienie z obywatelstwa polskiego).
