A defendant who is engaged in litigation, but feels the claimant may be unable to satisfy any costs order made against him may, in certain circumstances, apply to the court for an order for security for costs.
The rationale behind this is that a defendant will not usually have chosen to be embroiled in litigation (although his behaviour may have been such that the claimant had no other option but to commence proceedings). Defending a claim can cost a considerable amount of money. A defendant’s armoury to protect him from the legal costs he may incur includes making an application for security for costs under rule 7.27 of the High Court Rules 2009.
