The Part 47 Practice Direction (para 4.1) supplements CPR47.4 and defines the “appropriate office” where all applications and requests in detailed assessment proceedings must be made or filed.

The District Registry or the County Court hearing centre in which the case was being dealt with when the judgment or order was made or to which the case was subsequently transferred is the appropriate office. Where the County Court hearing centre is one of the courts in the Greater London area, the appropriate office is the SCCO. For a full list of those County Court hearing centres in the Greater London area, see PD47.4.2(1).

Where a tribunal, person or other body makes an order for detailed assessment, the appropriate office is a County Court hearing centre other than a County Court hearing centre in the Greater London area. For all other cases, including Court of Appeal cases, the appropriate office is the SCCO.

Default costs certificates should be issued and applications to set aside default costs certificates should be issued and heard in the relevant County Court hearing centre (including those within the Greater London area).
