The administration of the registration system is a matter for An tArd-Chláraitheoir, the Registrar-General of Births, Deaths and Marriages, and for local registrars who operate under his general direction.
An tArd-Chláraitheoir maintains an index of births at the General Register Office, Joyce House, 8-11 Lombard Street East, Dublin 2, which may be searched on payment of the statutory fee. Ideally, a person searching the indexes should know the date and place of birth, forename of the person concerned and the parents names. However, it may be possible to locate the relevant entry if only some of the details are available.
