“4.8 The practical application of this general principle raises a problem as to when, for the purpose of custody jurisdiction, proceedings for divorce, nullity or judicial separation should be regarded as coming to an end. The effect of existing law in all three United Kingdom countries is that once the court is duly seised of the matrimonial dispute, it retains jurisdiction to deal with questions relating to custody of and access to the children. This jurisdiction is retained however long ago the divorce was granted, however distant the connection of the child with the country in which the divorce took place, and however close and long-standing the child’s connection with some other part of the United Kingdom. The question we have to answer is whether, for the purposes of our scheme, the jurisdiction of the divorce court to make custody orders should continue so long as the child is within the appropriate age limit, i.e. 18 in England and Wales and Northern Ireland and 16 in Scotland. “4.9 We have reached the conclusion that a court dealing with divorce, nullity or judicial separation proceedings should remain entitled to exercise custody jurisdiction until the child attains the appropriate age, even where the child or his parents are or have become habitually resident elsewhere in the United Kingdom. Our main reason for reaching this conclusion is the impossibility of devising any general rule to the contrary effect which would not sometimes operate against the interests of the child’s welfare or against those of the parents. “4.10 Nevertheless, we recognise that in some cases it will be advantageous for issues as to custody and access to be determined by a court in a United Kingdom country other than that in which the proceedings for dissolution of the marriage are brought … “4.11 We therefore recommend as follows- Where a court in the United Kingdom has jurisdiction in proceedings for divorce, nullity of marriage or judicial separation, that court should continue to have jurisdiction to make custody orders in the course of those proceedings.”
“Therefore I conclude that section 2(1)(b)(i) does qualify section 42(2) and does require a connection, probably a temporal connection, to be established between "the question of making the order" and the matrimonial proceedings, but how that connection is to be defined is more difficult. In the light of the Explanatory Note to the Rules introducing the amendments consequent on Brussels II Revised, a purposive construction of Section 2(1)(b)(i) would support an interpretation of the provisions bringing it into line with the provisions of Brussels II Revised, and away from the UK based "continuing proceedings" jurisdiction. The time frame of the revoked FPR 2.40 is similar to the time frame for continuing jurisdiction based on divorce in Brussels II and Article 12 of Brussels II Revised. In my judgment to fall within the residual jurisdiction there must be proximity between the divorce proceedings and the court being asked to determine a question of making an order in relation to children. In any case it may be that essentially the same application or issue has been before the court, unresolved, for some time, but once an order has been made, then in my view the connection with the matrimonial proceedings would terminate.”
“Although I accept that the Court of Appeal decision in Lachaux supports the court taking a broad approach [to] this issue I do not read the decision as amounting to a boundless discretion where the mere existence of a divorce petition at the same time as applications in respect of children satisfy the condition.”
