The Civil Registration (Amendment) Act, 2005, does not relate to marriages and is concerned solely with payment of fees and allowances to registrars.
The Civil Registration Act, 2004, which contains provisions relating to marriage, does not contain any provisions concerning bigamy. The Act, however, does provide that correct information must be given to the Registrar of Marriages by the parties intending to marry. False information, including false information in relation to marital status, is an offence under Section 69 of the Act. This is currently covered in the Marriage Law (Ireland) Act, 1863 (26 Vic. Cap. 27), which will be repealed on commencement of Part 6 of the Civil Registration Act, 2004, which is expected to take place in the first half of 2007.
Bigamy has always been a specific offence and continues to be an offence under Section 57 of the Offences against the Person Act, 1861, which states that bigamy is committed when a person, who is a party to a valid subsisting marriage, goes through a ceremony of marriage with another.
