It is sufficient to refer to the date and name of the document and with whom it was contracted. Like most costs issues, that depends very much on the circumstances. However, there are also more qualitative considerations.

Certainly if the matter goes to assessment, in most cases the assessor will require further particulars of a short form bill to be able to consider the costs.
