All standard stuff. It is the court directions order. The hearing is set for 20th November. The claimant must pay the trial fee of £27 by 4pm on 23rd October. If they don't pay it by that deadline, the claim is struck out and they will be liable for your costs.
Should they pay it, then both parties have a deadline of 14 days before the hearing to submit their Witness Statements to the court (and each other). So, 6th November is the WS deadline.
If you've heard nothing by 4pm on 23rd October, come back and let us know. You will have to call the court and check whether the claimant has discontinued the claim and whether the hearing has been vacated.
Put the date in your diary. I suspect that they will discontinue. However, if they don't, the claim should not be heard anyway as the claim was never served within 4 months of it being issued. That is fatal to their claim.
