Ireland: document checklist
Every document you need for a Ireland citizenship-by-descent case — who issues it, how to request it, and roughly what it costs and takes.
Irish ancestor's civil birth certificate
- General Register Office (GRO) of Ireland, or GRONI for Northern Ireland
- Online via civilrecords.ie (GRO) or nidirect.gov.uk (GRONI)
- €20 (Ireland); £15 (Northern Ireland)
- 2–6 weeks
Must be an Irish civil birth certificate, not a church baptismal record.
Full chain of birth certificates (long-form)
- National/local vital records office for each person in the line
- Online or mail request
- $15–$50 each
- 1–4 weeks
Must be long-form certificates showing parents' names.
Marriage certificates for every generation
- GRO Ireland or equivalent registry in country of marriage
- Same as birth certificates
- $15–$50 each
- 1–4 weeks
Needed to show the chain of relationship wherever a name changed.
Parent's FBR registration certificate (great-grandparent claims only)
- Foreign Births Register, Irish Department of Foreign Affairs
- Contact the DFA for a replacement if the original is lost
- Replacement fee applies
- 2–4 weeks
You must prove your parent registered before your date of birth.
FBR application (form, witness, photos)
- Irish Department of Foreign Affairs
- Online application on the DFA website, then the signed witnessed form and original documents by post
- €278 (adults); €153 (children under 18)
- ~9–12 months processing — this is the main bottleneck
The form must be witnessed by a professional from the DFA's approved list (doctor, lawyer, teacher, police officer, etc.). Fees and processing times change periodically — confirm before submitting.
Naturalisation by Irish Association application
- Immigration Service Delivery (ISD), Department of Justice
- Applied through irishimmigration.ie — a different department and process from FBR entirely
- Naturalisation application fee (set by ISD) plus a certification fee if granted — confirm current amounts before applying
- 12–19+ months, longer if the discretionary review needs more evidence
Fallback for cases that don't qualify for FBR. Requires a case built around four published categories (experiential, family, cultural connection, and establishment in Ireland), scoring 50%+ in at least two. Genuinely discretionary — not a guaranteed alternative to FBR.
