You will get a more detailed letter containing information on the date of the court hearing, the date by which the claimant has to pay the court fee, and the date by which documents such as Witness Statements need to be served.
A good possibility is that the fee has to be paid before any documentation, so that if the claimant discontinues rather than paying the fee, that involves you with the least effort. But no guarantees.
The good news is that DCB Legal usually discontinues.
