Overview
AG-MAR-01 is Antigua and Barbuda's marriage-based acquisition route: the registration of the foreign spouse of an Antiguan and Barbudan citizen. Its defining feature — and the reason it is a signature route — is that it is not a discretionary naturalisation grant but a constitutional entitlement. Section 114(1)(b) of the Antigua and Barbuda Constitution Order 1981 provides that a person married to a citizen "shall be entitled, upon making application, to be registered" as a citizen, provided two conditions are met: the marriage has subsisted for upwards of three years, and the spouses are not living apart under a decree of a competent court or a deed of separation. Because the right is conferred by the supreme law of the land, the responsible authority's role is confined to verifying that those preconditions exist; it has no discretion to refuse a properly-made application on policy or convenience grounds. The route is doctrinally framed by the country's signature citizenship litigation, Oliveira v Attorney General, which ran from the Eastern Caribbean Supreme Court High Court (Claim No. ANUHCV2008/0449, 2009) to the Judicial Committee of the Privy Council ([2016] UKPC 24). The High Court established the entitlement character of s.114; the Privy Council added the temporal dimension — that the State must conclude a s.114 registration within a reasonable time, which the Board fixed, for a straightforward marriage application, at a period of one year from application to registration as the general outside limit. This route document covers the registration entitlement, the three-year subsisting-marriage requirement, the continuing-marriage (not-living-apart) condition, the limited statutory refusal powers that do and do not bite on the marriage limb, and the Oliveira ratio. It is distinguished throughout from the discretionary registration and naturalisation routes (AG-REG-01, AG-NAT-01) and from the derivative child route (AG-CBN-01). This is legal research, not legal advice.
Legal basis
The operative provision is Constitution Order 1981 s.114, headed "Persons entitled to citizenship by registration after commencement of this Constitution." The chapeau is mandatory in form: "Subject to the provisions of paragraph (e) of section 112 and of section 117 of this Constitution, the following persons shall be entitled, upon making application, to be registered on or after 1st November 1981—" (s.114(1), verbatim,.txt). The use of "shall be entitled" — not "may be registered" — is the textual root of the entitlement reading and the distinction from the discretionary verbs ("the Minister may at his discretion") used in the Citizenship Act. The general marriage limb is s.114(1)(b): "any person who— i. was married to a person who is or becomes a citizen; or ii. was married to a person who was or, but for his or her death, would have become a citizen: Provided that no application shall be allowed from such person before the marriage has subsisted for upwards of three years and that such person is not, or was not at the time of the death of the spouse, living apart from the spouse under a decree of a competent court or a deed of separation" (verbatim). A narrower independence-cohort limb, s.114(1)(a), entitles a person who, on 31 October 1981, was married to a person who becomes a citizen by virtue of s.112 (or who would have but for death before 1 November 1981) to registration, subject to the same not-living-apart condition but without the three-year minimum — that limb is keyed to the independence cohort and is now of historical reach only. The entitlement is operationalised, not created, by statute. Cap.22 s.3(4) expressly carves the s.114 marriage entitlees out of the Act's discretionary machinery: "Subsections (2) and (3) of this section do not apply to any person who under section 112(e) of the Constitution becomes or under section 114(1)(a), 114(1)(b) or 114(1)(c) of the Constitution is entitled to be registered" (verbatim,.txt). On registration, Cap.22 s.5 provides the person "shall be a citizen of Antigua and Barbuda by registration as from the date on which he is registered" (verbatim). The signature judicial gloss is the JCPC's: per Oliveira [2016] UKPC 24, "a period of one year, from application to registration, for the consideration of a section 114 application is in general the outside" limit (verbatim, BAILII [2016] UKPC 24). The High Court below had already declared the entitlement at para 101 [blocked]: "It is declared that Mr. Clive Oliveira is entitled to apply to the relevant authorities to be registered as a citizen of Antigua and Barbuda" (verbatim, ECSC_ANUHCV2008_0449.txt).
Example scenarios
ENTITLED — AG-MAR-01. The marriage registration entitlement under Constitution s.114(1)(b) becomes available when the marriage has 'subsisted upwards of three years.' At 14 months, the threshold HAS NOT YET BEEN MET. The three-year marriage duration is a precondition, not a processing timeline. She becomes eligible to apply once the marriage reaches 3 years and 1 day (approximately 22 months from now). Once eligible and having applied, per Oliveira [2016] UKPC 24, processing beyond 1 year = constitutional breach entitling damages.
Constitution s.114(1)(b): marriage must have 'subsisted upwards of three years.' 14 months < 3 years. She is not yet eligible to apply. Oliveira [2016] UKPC 24 (JCPC): delay beyond 1 year from application = constitutional breach, but that remedy accrues only once she has applied after meeting the 3-year threshold. AG-MAR-01 route doc confirms the 3-year threshold and Oliveira standard.
ENTITLED and has legal recourse. Under Constitution s.114(1)(b) the entitlement is constitutional, not discretionary. Oliveira [2016] UKPC 24 (JCPC) established that delay beyond approximately one year from a straightforward application constitutes a constitutional breach and entitles the applicant to damages. At 18 months post-application, he is past the Oliveira benchmark. He should seek legal representation to apply for a mandatory order and potentially damages. The state has 'no discretion to fetter the right' (Oliveira High Court language confirmed in route doc).
AG-MAR-01 route doc pins Oliveira v AG [2016] UKPC 24 as the authoritative processing-standard case. 1-year benchmark for straightforward applications. At 18 months, constitutional breach is established per that standard. Cap.22 s.3(7)/(8) ministerial refusal powers do NOT reach s.114(1)(b) marriage applicants.
POTENTIALLY INELIGIBLE — AG-MAR-01. The s.114(1)(b) entitlement requires that the marriage has 'subsisted upwards of three years' AND that the spouses are 'not living apart under a separation order or deed of separation.' If the couple is living apart pursuant to a formal deed of separation, the entitlement is suspended. If they are merely informally separated with no legal instrument, the formal condition may not be triggered. Legal advice required to assess the specific separation instrument, if any.
Constitution s.114(1)(b) two-part test: (1) marriage duration 4+ years (met) AND (2) not living apart under a decree nisi, decree of judicial separation, or deed of separation (potentially triggered). AG-MAR-01 route doc confirms both conditions must be satisfied. Informal separation without a formal decree or deed may not satisfy the exclusion condition — but formal deed would.
UNCERTAIN — NLR-MED on AG-MAR-01 for same-sex couples. Constitution s.114(1)(b) refers to 'a person who is married to a citizen.' AG domestic law does not recognise same-sex marriage. Whether a same-sex marriage contracted abroad is treated as a 'marriage' for the purpose of s.114(1)(b) is not authoritatively determined in AG case law as of 2026-06-14. This requires legal advice and potentially litigation. The refusal risk is material. Alternative: CBI routes are available regardless of marital status.
AG-MAR-01 route doc does not address same-sex marriage recognition. AG's Marriage Act reflects traditional marriage. International private law recognition of foreign same-sex marriages in a jurisdiction that does not recognise them domestically is unresolved in AG case law. This is a genuine legal ambiguity requiring professional advice — not a settled question.
ELIGIBLE — AG-MAR-01. The marriage has 'subsisted upwards of three years' (3 years 2 months > 3 years). They are not living apart under a decree or deed of separation. The husband is entitled under Constitution s.114(1)(b) to apply for registration. No good-character, means, language, or civics requirement under the constitutional text. Processing: approximately 12 months per the Oliveira standard; beyond that triggers constitutional breach.
AG-MAR-01: Constitution s.114(1)(b) — marriage must have subsisted 'upwards of three years.' 3 years 2 months satisfies this. Not living apart under any separation order. Constitutional entitlement. Oliveira [2016] UKPC 24: 1-year processing standard for straightforward applications.
BORDERLINE — AG-MAR-01. The constitutional requirement is that the marriage must have 'subsisted upwards of three years.' On exactly the 3-year anniversary, the marriage has subsisted exactly 3 years — arguably NOT 'upwards of three years' in the strict sense. One more day (3 years and 1 day) would clearly qualify. Legal practice varies on strict vs. liberal interpretation of 'upwards of three years.' Caution: wait one additional day before filing to avoid a technical objection.
AG-MAR-01 route doc: Constitution s.114(1)(b) — 'upwards of three years.' 'Upwards of' in Commonwealth constitutional drafting typically means 'more than,' implying the period must exceed 3 years, not merely equal it. One extra day eliminates any ambiguity. This is a drafting nuance with practical significance for applicants on the boundary date.
