I have made inquiries of the Registrar General and he has informed me that the position is as follows:
Where a person wishes to marry in Ireland, and has been granted a divorce in another jurisdiction, legal recognition of this divorce under Irish law is examined in the General Register Office. Legal recognition of foreign divorces in Ireland is a complex area of law involving proof of domicile in a country where the divorce has been granted.
This case involves the recognition of a foreign divorce and the examination of the divorce is ongoing. The General Register Office will inform the registrar involved as soon as this process is concluded.
