Rule 117 Requirement to assess costs by the detailed procedureI1
England and Wales
Where the costs of any person are payable as an expense out of the assets of the company, the amount payable must be decided by detailed assessment unless agreed between the postal administrator and the person entitled to payment.
In the absence of such agreement as is mentioned in paragraph (1) of this Rule, the postal administrator may serve notice requiring that person to commence detailed assessment proceedings in accordance with CPR Part 47 (procedure for detailed assessment of costs and default provisions).
Where the costs of any person employed by a postal administrator in postal administration proceedings are required to be decided by detailed assessment or fixed by order of the court, the postal administrator may make payments on account to such person in respect of those costs provided that person undertakes in writing—
to repay as soon as reasonably practicable any money which may, when detailed assessment is made, prove to have been overpaid; and
to pay interest on any such sum as is mentioned in sub-paragraph (a) at the rate specified in section 17 of the Judgments Act 1838 on the date payment was made and for the period beginning with the date of payment and ending with the date of repayment.
In any proceedings before the court, the court may order costs to be decided by detailed assessment.
