Do not start in the wrong process.
The Irish government distinguishes the parent-born route from the grandparent route. A parent born on the island of Ireland can make the child an Irish citizen from birth, while a grandparent-based claimant generally becomes a citizen through registration.
The passport application must still prove identity, the parent-child link, and the Irish-born parent’s civil record.

Prepare the relationship and identity evidence.
- Your full civil birth certificate showing the parent relationship.
- Your Irish-born parent’s full civil birth certificate.
- Marriage, adoption, or name-change evidence where the names do not align.
- The identity, photograph, witness, and address materials required by the current passport application.

Order the right version of your parent’s Irish birth certificate.
The Passport Service asks for your Irish-born parent’s full original civil birth certificate, the version that names their parents. It doesn’t accept baptismal certificates, birth certificates that leave out the parents, or laminated certificates.
For a birth in what is now the Republic of Ireland, order the full standard birth certificate from the General Register Office (GRO): online through the HSE’s certificate service, by phone or at a civil registration service, or by emailing the GRO’s application form. For a Northern Ireland birth from 1922 on, order the long birth certificate from the General Register Office Northern Ireland (GRONI). Northern Ireland births from 1864 to 1921 are held by both offices.
If your parent’s name on your birth certificate differs from the name on their Irish birth certificate, link the two with the original civil marriage certificate, a separation agreement, a judicial separation order or a divorce decree. Court documents must be certified by a solicitor or by the court.

What you don’t need for the parent-born route.
- Foreign Birth Registration. You’re already an Irish citizen, so you apply for a passport instead.
- An apostille or legalisation on your birth certificates. The Passport Service’s document list doesn’t ask for one.
- A translation of an English-language birth certificate. Only your proof of name and proof of address need a translation into English or Irish, and only when they’re in another language.
- An apostille on your photo ID. The Passport Service asks for a copy of your foreign passport or driving licence certified by a Garda, solicitor, notary or the issuing authority. That certification is all it asks for.

Questions to resolve before you act
Do I need Foreign Birth Registration if my parent was born in Ireland?
The Department of Foreign Affairs says a person born abroad to a parent born on the island of Ireland is already an Irish citizen and does not use FBR to become one.
Which birth certificate of my Irish-born parent do I need for my first Irish passport?
Their full original civil birth certificate, the version that names their parents. The Passport Service doesn’t accept baptismal certificates, laminated certificates, or birth certificates that leave out the parents.
Do I need an apostille for a first Irish passport through my parent?
No. The Passport Service’s document list doesn’t ask for an apostille or legalisation. Your photo ID copy is certified by a Garda, solicitor, notary or the issuing authority instead.
My parent was born in Northern Ireland. Where do I get their birth certificate?
For a birth from 1922 on, from the General Register Office Northern Ireland (GRONI); ask for the long birth certificate, which names the parents. For a birth from 1864 to 1921, the General Register Office in Ireland holds it too.
