A foreign divorce is a dissolution of marriage obtained outside the UK or Ireland, typically by court order or equivalent authority in another state. In legal practice, the issue is whether and when that overseas divorce is recognised so that the parties are treated as divorced for purposes such as remarriage, financial remedies, succession, pensions and immigration.In England and Wales and Northern Ireland, statutory rules on recognition are mainly found in the Family Law Act 1986, supplemented by common law and retained EU law for certain historic cases. In Scotland, recognition is governed by the Family Law (Scotland) Act 1985 and related provisions. In Ireland, foreign divorces are dealt with principally under the Domicile and Recognition of Foreign Divorces Act 1986 and subsequent legislation.Core requirements typically concern: (i) the validity of the divorce in the country where it was granted; (ii) jurisdictional connection (e.g. domicile, habitual residence, nationality); and (iii) procedural fairness and public policy. Usage and concepts are broadly consistent across the four jurisdictions, but the detailed statutory tests and the impact of past EU instruments and international conventions differ and must be checked carefully in each jurisdiction.
