Pre-1983 CUKC by Birth (Closed Cohort)

This route describes a person born on UK soil BEFORE 1 January 1983 who was a CUKC by birth under BNA 1948 s. 4, and the status that person held from the 1983 partition onward. It is not a present-day acquisition pathway: eligibility was fixed at birth (pre-1983) and the resulting modern status was determined automatically at commencement. The cohort comprises people now generally aged 43+ (born ≤31.12.1982). The practical question for such a person today is which of the four BNA 1981 statuses they hold (BC / BOTC / BOC / BS), which turns on their connection to the UK versus a dependent territory and, for the BC limb, whether they had the right of abode immediately before 1.1.1983.

Because acquisition was automatic and historical, there are no application 'requirements' for the original CUKC-by-birth event: the sole condition under BNA 1948 s. 4 was birth on UK soil before 1.1.1983 (subject to the diplomat/enemy-alien common-law exceptions). The 1983 partition into BC/BOTC/BOC/BS was likewise automatic by operation of law (BNA 1981 ss. 11, 23, 26, 30) — no application was needed and none could be made to choose a status. The only contemporary 'requirements' arise where a present-day individual must EVIDENCE their resulting status (see process_and_authority) or pursue a distinct remedial registration route (e.g. BNA 1981 s. 4C for pre-1983 maternal-line cases — a separate route, not this one).

No live grant process exists for this closed cohort; status vested automatically on 1.1.1983. A present-day person who is a British citizen by virtue of s. 11 evidences it by applying to HM Passport Office for a British passport, or to the Home Office (UK Visas and Immigration) for confirmation of status. A person who believes they hold the right of abode (e.g. legacy Commonwealth-citizen right of abode under IA 1971 s. 2(1)(b)) may apply for a Certificate of Entitlement to the right of abode. The competent authority for nationality status is the Secretary of State for the Home Department (Home Office); passports are issued by HM Passport Office. There is no tribunal 'eligibility' decision for the historic event itself — disputes concern proof of facts (place/date of birth, parental status, territory connection).

There is NO acquisition fee for this route: CUKC-by-birth (pre-1983) and the 1983 partition were automatic and free by operation of law. Contemporary costs are incidental and relate only to EVIDENCING status, not acquiring it: a standard UK passport application carries the HM Passport Office passport fee (not a nationality fee), and a Certificate of Entitlement to the right of abode carries a separate fee. The naturalisation/registration fee schedule (e.g. naturalisation £1,709 + £130 ceremony = £1,839 to certificate, uprated 8 Apr 2026) does NOT apply to this route because no naturalisation or registration is involved. Distinct remedial registration routes (e.g. s. 4C) carry their own fees and are handled in those routes.

Although this closed cohort generates little modern litigation directly, the surrounding jurisprudence frames it. Roehrig v SSHD [2024] EWCA Civ 240 (CA, 12.3.2024) confirms how 'settled'/right-to-remain concepts are read strictly — relevant by analogy to the right-of-abode test under s. 11(1). The British Nationality (Regularisation of Past Practice) Act 2023 (c. 27), inserting BNA 1981 s. 50B, retroactively cured certain EEA free-movement residents for the remedial period 1.1.1983–1.10.2000 — a reminder that partition-era status questions can be reopened by statute. Pham v SSHD [2015] UKSC 19 (de facto vs de jure statelessness) bears on the s. 11(2) stateless-registration carve-out. These are framing authorities; none alters the verbatim ss. 11/23/26 partition mechanics.
