Money Claim Online - which is the online county court procedure - i'm puzzled about issue regarding evidence- do you have to submit this online or post? - AND i assume evidence is only required if defendant disputes?
Money claim online is for simple matters which do not require full pleadings. You submit your claim online.
If the D does not defend you get judgement in default.
If the D does defend, the case will be allocated to the Court for the convenience of D. Thereafter directions will be given for the submission of evidence which has to be in a form laid down by the CPR, has to be submitted in writing and served on both the Court and the other party.
Unless anyone here can provide a definitive answer, I suggest phoning the helpline (0845-601 5935, 0900-1700, Mon-Fri) to get the information you require.
Oh, I see that Barmaid has been posting while I've been researching (and typing very slowly). My post is probably irrelevant but, at least, it provides contact details if you need further advice.
