Who qualifies
Eligibility for §3(3)(b): (1) child found in Hungary (on Hungarian territory); (2) parentage is UNKNOWN — neither parent is identifiable. This is the critical distinguishing element: §3(3)(b) requires that the child's parents cannot be identified. Once parentage is established, §3(3)(b) no longer provides the basis; instead §3(1) (Hungarian-citizen parent) or §3(3)(a) (stateless resident parents) may apply. No age cap; applies to newborns and children of unknown parentage.
Requirements
No application required for §3(3)(b) presumption. Practical documentation: (1) establishment by child-protection/guardianship authority (gyámhatóság) that the child is of unknown parentage; (2) birth registration (anyakönyv) noting the §3(3)(b) presumption; (3) állampolgársági bizonyítvány from BFKH if formal certification is needed. Rebuttal: if foreign nationality or non-Hungarian parentage is later affirmatively established under §3(4), the presumption ceases.
How to apply
Process: statutory presumption operates automatically at the moment a child of unknown parentage is found in Hungary. Practical steps: (1) gyámhatóság/gyermekvédelmi szerv establishes foundling status and initiates any parentage investigation; (2) anyakönyv registration of the child as Hungarian by operation of §3(3)(b); (3) állampolgársági bizonyítvány from BFKH if formal proof needed. The child's welfare/adoption proceedings (1997. évi XXXI. törvény) proceed in parallel but are separate from the citizenship determination.
Timeline
Timeline: §3(3)(b) presumption operates automatically when the child of unknown parentage is found in Hungary. No citizenship application is required. Birth registration via anyakönyv should occur promptly. Állampolgársági bizonyítvány from BFKH — no statutory maximum; practice-based timing. The presumption has no expiry — it continues until affirmatively rebutted under §3(4).
Fees & cost
Illetékmentes (fee-free) since 2021-01-01. All first-instance administrative citizenship procedures are fee-free (kormany.hu; 2017. évi II. törvény repeal of Itv. Melléklet XV. cím items). No statutory citizenship fee applies to the §3(3)(b) presumption or to the állampolgársági bizonyítvány.
Legal basis
Status: OPEN era spanning W1–W7. §3(3)(b) has been in continuous force since the 1879:L era (in force 1880-01-08); the 2025 reforms did not alter §3(3)(b) — Act CXXVI/2025 added §3(3)(c) as an extension. No amendment to §3(3)(b) is pending as of 2026-05-31. All seven temporal windows are relevant to understanding the historical lineage of this route, although only W5–W7 represent current operational time.
Competent authority
Competent authority for citizenship determination: citizenship-matters organ (állampolgársági ügyekben eljáró szerv — BFKH). Gyámhatóság handles child welfare/adoption proceedings separately. OIF handles immigration/asylum/Guest Investor only — NOT foundling citizenship matters. Judicial review of citizenship-determination decisions: Fővárosi Törvényszék within 30 days of notification.
Exceptions & edge cases
Unlike the §3(3)(a) stateless-parents limb, §3(3)(b) imposes NO residence requirement and no condition on the parents' status — it needs only that a child of unknown parentage be found in Hungary — making it the broadest territorial presumption. It is rebuttable under §3(4): the Hungarian-citizen presumption falls only if non-Hungarian parentage or a foreign nationality is affirmatively established. Status is confirmed declaratively (not by naturalisation) through an állampolgársági bizonyítvány issued by the citizenship-matters organ under Act LV §11 (valid three years), with the immigration authority OIF having no role.
Example scenarios
Baby found in Budapest (classic foundling)
An infant of unknown parentage is found abandoned in a Budapest park. Authorities must determine the child's nationality.
BTH-03 (§3(3)(b)) is the classic foundling presumption: a child of unknown parentage found in Hungary is presumed Hungarian until the contrary is proven — a rule descending from the 1879:L-era regime, predating Act LV/1993 by over a century. BTH-05 governs the rebuttable-presumption mechanics.
