Until recently we would never advise using MCOL to submit a defence. However, due to recent systemic failures within the CNBC and many people receiving CCJs in default, even though they had responded to the claims, we reviewed that advice. That coupled with some improvements to the MCOL system, we now advise that the MCOL can be used to submit a defence and that is now preferred because it is entered into the system automatically and instantly.
Because there isa nothing showing on the MCOL history, I would be slightly worried that your defence could be one of the many that went missing and a judgment in default may have already been issued. So, you should urgently contact the CNBC and find out the status of the claim.
