9.7.5 Detailed assessment of costs
As discussed above, at the consequentials hearing, the trial judge will typically give two directions as to costs: (i) a decision on which party should receive its costs and the percentage of its costs that it should receive, and (ii) an order for an interim payment.
In many cases, the parties will reflect on the comments from the trial judge and negotiate a sum to be paid from one to the other in respect of costs. Invariably, if there is to be an appeal, the money will be paid subject to an undertaking to repay in the event of a successful appeal or will be held in escrow.
In the event that costs cannot be negotiated, the rules provide a framework for the detailed assessment of costs by a specialist costs judge in a procedure governed by CPR 47.
