Irish Citizenship Through A Grandparent Born In Ireland?

Posted in News on 14th August 2018

Become an Irish Citizen by Naturalisation

If your Grandparent is/was an Irish Born Person, they were automatically a Citizen of Ireland. Even if they emigrated.  Any Child of theirs which contain Parent/s name/s on their Birth Certificate, are also considered an Irish Citizen.  They simply need to be added to the Foreign Birth Register if born outside Ireland.  The entitlement to claim Citizenship as a Grandchild of an Irish Born Person is automatic.  The procedure is quite strict. The necessary documents must first be submitted for Citizenship before an Irish Passport can be obtained.  Thereafter, Passport applications should be made through the Irish Embassy or Consulate in your Country of Residence  (Charges will apply)

The documents required for Irish Citizenship by Grandparent Descent are as follows:

  1. Your own Long Form Civil Birth Certificate but Sourced from your Country of Birth
  2. Original Civil Marriage Certificate of your parents (if applicable) and Sourced from the Country of Marriage
  3. Original Long Form Civil Birth Certificate of your Parent and Sourced from the Country of their Birth
  4. Parents Civil Marriage Certificate but Sourced from the Country of Marriage
  5. Long Form Civil Birth Certificate of Irish Born Grandparent which can be Sourced through
  6. Civil Marriage Certificate of Grandparents if married in Ireland can be Sourced through, otherwise from the Country of Marriage
  7. Civil Death Certificate of Grandparent, if deceased which should be Sourced from the Country where the Death actually occurred.
