Article 22U.K.Grounds of non-recognition for judgments relating to divorce, legal separation or marriage annulment
A judgment relating to a divorce, legal separation or marriage annulment shall not be recognised:
if such recognition is manifestly contrary to the public policy of the Member State in which recognition is sought;
where it was given in default of appearance, if the respondent was not served with the document which instituted the proceedings or with an equivalent document in sufficient time and in such a way as to enable the respondent to arrange for his or her defence unless it is determined that the respondent has accepted the judgment unequivocally;
if it is irreconcilable with a judgment given in proceedings between the same parties in the Member State in which recognition is sought; or
if it is irreconcilable with an earlier judgment given in another Member State or in a non-Member State between the same parties, provided that the earlier judgment fulfils the conditions necessary for its recognition in the Member State in which recognition is sought.
