The claimant is not under an obligation to reply to the defence and, if he does not do so, it is not to be taken as admitting anything which is raised in the defence. The most usual reply to a defence is a counterclaim and this may also include a reply as where the claimant wishes to allege facts in answer to the defence which were not contained in the particulars of claim. In general, therefore, a reply should be limited to a statement of new facts the claimant intends to prove to defeat the defence.
