The basis of jurisdiction in matrimonial causes under the Matrimonial Causes Act, 1970, is domicile. It is the domicile of a person that confers jurisdiction on the court to entertain his or her petition for dissolution of marriage. Where the domicile of a petitioner is not established the court will lack jurisdiction to decree a dissolution of marriage.
