"The guidance given in Denton may be summarised as follows: a judge should address an application for relief from sanction in three stages. The first stage is to identify and assess the seriousness and significance of the "failure to comply with any rule, practice direction or court order" which engages r.3.9(1). If the breach is neither serious nor significant, the court is unlikely to need to spend much time on the second and third stages. The second stage is to consider why the default occurred. The third stage is to evaluate all the circumstances of the case, so as to enable the court to deal justly with the application including r.3.9(1)(a)(b). The court also gave guidance as to the importance of penalising parties who unreasonably oppose applications for relief from sanctions."
“In my view, the fact of a jurisdictional dispute is relevant, but does not weigh too heavily.”
“There is no doubt that the fact of a dispute about jurisdiction does not prevent the court from making an interim maintenance award, although if the jurisdictional basis of the applicant's claim is doubtful, the court will be appropriately cautious when considering (i) whether such an award should be made and (ii) the quantification thereof.”
“From these cases I derive the following principles: The sole criterion to be applied in determining the application is "reasonableness" (s22 Matrimonial Causes Act 1973 ), which, to my mind, is synonymous with "fairness". A very important factor in determining fairness is the marital standard of living (F v F). This is not to say that the exercise is merely to replicate that standard (M v M). In every maintenance pending suit application there should be a specific maintenance pending suit budget which excludes capital or long term expenditure more aptly to be considered on a final hearing (F v F). That budget should be examined critically in every case to exclude forensic exaggeration (F v F). Where the affidavit or Form E disclosure by the payer is obviously deficient the court should not hesitate to make robust assumptions about his ability to pay. The court is not confined to the mere say-so of the payer as to the extent of his income or resources (G v G, M v M). In such a situation the court should err in favour of the payee.”
"….when adjudicating the question of interim maintenance, where there has been a prenuptial agreement, the court should seek to apply the terms of the prenuptial agreement as closely and practically as it can, unless the evidence of the wife in support of her application demonstrates, to a convincing standard, that she has a prospect of satisfying a court that the agreement should not be upheld."
