If you contact Fr Delargy in good time he will inform you of all the requirements, civil as well as religious.
However, it is good to be informed of the requirements of the civil law in Northern Ireland.
The following information is taken from the NI Direct Government Services website.
Registration of marriage
The Registrar is responsible for the registration of all marriages -
The Registrar will complete the registration process.
Couples marrying by religious ceremony should ensure that the schedule is returned to the Registrar within three days, either in person or by post.
The schedule should be signed by the couple, two witnesses and the Officiant after the ceremony.
If you do not return the marriage schedule you will be unable to obtain a certified copy of your marriage.
After the marriage has been registered, you can obtain a copy of the marriage certificate from the Registrar on payment of the appropriate fee.
Couples who are married at a religious ceremony will not be able to obtain a marriage certificate immediately after the ceremony.
