"... Section 18 could have provided that, once England and Wales was to be regarded as the appropriate forum under section 16, then the case was to be treated as a purely English proceeding for financial relief. But it did not do so. Instead a more flexible approach was deliberately adopted. There will be some cases, with a strong English connection, where it will be appropriate to ask what provision would have been made had the divorce been granted in England. There will be other cases where the connection is not strong and a spouse has received adequate provision from the foreign court. Then it will not be appropriate for Part III to be used simply as a tool to "top-up" that provision to that which she would have received in an English divorce."
"73. The amount of financial provision will depend on all the circumstances of the case and there is no rule that it should be the minimum amount required to overcome injustice. The following general principles should be applied. First, primary consideration must be given to the welfare of any children of the marriage. This can cut both ways as the children may be being supported by the foreign spouse. Second, it will never be appropriate to make an order which gives the claimant more than she or he would have been awarded had all proceedings taken place within this jurisdiction. Third, where possible the order should have the result that provision is made for the reasonable needs of each spouse. Subject to these principles, the court has a broad discretion. The reasons why it was appropriate for an order to be made in England are among the circumstances to be taken into account in deciding what order should be made. Where the English connections of the case are very strong there may be no reason why the application should not be treated as if it were made in purely English proceedings."
