Family analysis: In Villiers, the Court of Appeal allowed the wife’s appeal against a decision of Mr Justice Mostyn dismissing her application under section 27 of the Matrimonial Causes Act 1973 (MCA 1973). The Court of Appeal found that the court below was wrong for three reasons. First, that the ‘relevant date’ to assess an application under MCA 1973, s 27 should be the date of the hearing, not the date of the application, and alternatively, it was not procedurally fair for the judge below to raise a new material issue at a final hearing and then dismiss an application on that basis, given the history of the proceedings. In addition, that the common law principle that a husband has a duty to provide for his wife is outdated and no longer has any relevance to MCA 1973, s 27. Finally, that the jurisdiction for divorce proceedings is entirely separate from the jurisdiction for maintenance and an applicant may choose the best forum available. Jessica O’Driscoll-Breen, barrister at QEB Chambers, considers the issues.
