It is hereby declared that the family court has jurisdiction to hear an application by or against a person residing outside England and Wales for the discharge or variation of an attachment of earnings order made by the family court to secure maintenance payments; and where such an application is made, the following provisions shall have effect.
If the person resides in Scotland or Northern Ireland, section 15 of the Maintenance Orders Act 1950 (which relates to the service of process on persons residing in those countries) shall have effect in relation to the application as it has effect in relation to the proceedings therein mentioned.
Subject to the following subsection, if the person resides outside the United Kingdom and does not appear at the time and place appointed for the hearing of the application, the court may, if it thinks it reasonable in all the circumstances to do so, proceed to hear and determine the application at the time and place appointed for the hearing, or for any adjourned hearing, in like manner as if the person had then appeared.
Subsection (3) above shall apply only if it is proved to the satisfaction of the court, on oath or in such other manner as may be prescribed, that the applicant has taken such steps as may be prescribed to give to the said person notice of the application and of the time and place appointed for the hearing of it.
