“Where, in England and Wales, a limited company is Plaintiff [Claimant] in an action, or other legal proceeding, the court having jurisdiction in the matter may, if it appears by credible testimony that there is reason to believe that the company will be unable to pay the Defendant's costs if successful in his defence, will require sufficient security to be given for those costs and may stay all proceedings until the security is given.”
“The trend of authority makes it plain that, even though a counterclaiming defendant may technically be ordered to give security for the costs of a plaintiff against whom he counterclaims, such an order should not ordinarily be made if all the defendant is doing in substance is to defend himself. Such an approach is consistent with the general rule that security may not be ordered against a defendant. So, the question may arise, as a question of substance, not formality or pleading: 'Is the defendant simply defending himself, or is he going beyond mere self-defence and launching a cross-claim with an independent vitality of its own?’”
