Act V of 1957 on Hungarian Citizenship (superseded, but historically operative)
1957. évi V. törvény a magyar állampolgárságról
In force from 1 October 1957 to 30 September 1993, this earlier law is the source of the historical loss events that decide whether a family's line qualifies for verification today or needs simplified naturalisation instead. Superseded by Act LV of 1993, which does not apply retroactively.
What this law actually does
Voluntary acquisition of a foreign citizenship caused automatic loss of Hungarian citizenship
Living abroad for 10 or more consecutive years without maintaining Hungarian registration also caused automatic loss, independent of foreign naturalisation
From 1957 onward, marriage to a foreigner had no effect on a woman's citizenship — a change from the pre-1957 rules (automatic loss on marriage before 1922; loss only on actual foreign naturalisation, 1922–1957)
