No application for an order for financial relief shall be made under this Part of this Act unless the leave of the court has been obtained in accordance with rules of court; and the court shall not grant leave unless it considers that there is substantial ground for the making of an application for such an order.
The court may grant leave under this section notwithstanding that an order has been made by a court in a country outside England and Wales requiring the other party to the marriage to make any payment or transfer any property to the applicant or a child of the family.
Leave under this section may be granted subject to such conditions as the court thinks fit.
