Descent via grandparent (independence-acquisition test; no standalone s.5A)

Establishing an s.112(b)-based citizenship claim typically requires assembling the following chain of documents: For the grandparent (the qualifying ancestor): - Birth certificate of the grandparent, showing birth in Antigua (under any of the pre-independence territorial designations covered by s.127(15)); or - Naturalization certificate or registration certificate issued while the grandparent was resident in Antigua (CUKC-era documents, typically held by UK National Archives or Antiguan national records). For the parent (the s.112(b) citizen): - Birth certificate of the parent, showing birth outside Antigua (establishing they were not themselves born in Antigua, making their s.112(b) claim dependent on the grandparent connection). - Evidence of the parent being alive on 1 November 1981 (date of birth document or other life records). - Antiguan citizen's passport (if previously issued) or ministerial certificate of citizenship under Cap.22 s.12 confirming citizenship at independence. For the claimant (the applicant): - Foreign birth certificate, establishing birth outside Antigua and Barbuda and identifying the parent. - If the claimant is themselves an adult born after 1 November 1981, evidence that the parent was a citizen "by virtue of section 112" at the date of the claimant's birth (not merely a citizen by descent). - Documentary evidence of the parent-child relationship (where contested or the child is born out of wedlock: mother's documentation; DNA evidence may be relevant in some cases). For grandchild scenario (generation 3 — where this route DOES NOT apply): A claimant who is the grandchild of an s.112(b) citizen but whose parent is only a citizen by descent (s.113(b)) should be advised at the documentation stage that the automatic citizenship entitlement is cut off; they must pursue naturalisation or another pathway. The documentation package for such a claimant would differ fundamentally from the AG-DSC-03 chain described above. Note: The Citizenship Regulations Cap.22 (2023 subsidiary regulations — scanned, no text layer) may specify additional mandatory exhibits; the above represents the minimum framework inferable from the primary Constitution and Act texts.
