It is assumed for the purposes of this answer that the Family Procedure Rules 2010 (FPR 2010) in their amended form after 6 April 2022 apply. The normal method of enforcing an order of the type referred to would be by means of a contempt application under FPR 2010, SI 2010/2955, Pt 37. However, it would appear that the original order has only been served on the solicitors then acting for the party in default by e-mail. Normally, such service would suffice (FPR 2010, SI 2010/2955, 26.1 subject to FPR 2010, PD 6A, paras 4.2–4.6). This facility to serve by e-mail without the court's permission is overridden by the requirements of a contempt application contained in FPR 2010, SI 2010/2955,
