If a vehicle is seen as being involved in a road traffic offence the registered keeper is identified by reference to DVLA records.
A Notice of Intended Prosecution (NiP) is sent within 14 days of the incident to the registered keeper under Section 172 of the Road Traffic Act requiring the keeper to provide the identity of the driver at the time of an alleged road traffic offence.
Failure to provide the identity on time will inevitably lead to prosecution for non compliance

You say you named the driver as soon as you knew there was going to be a court case (post 9) but then you suggest nothing was known about the matter until you were discussing a different fine with the fines officer who told you a fine had already been imposed(post 13).

Sorry two different cases, the first case eventually got a court date letter, but nothing before that and this is what brought it to our attention. After failing to disclose for that one, which we had done immediately we knew about it, we discovered the other fine via the fines office, for which absolutely no papers had been received from anybody.
sorry to confuse.

It is almost impossible to prove that documents haven't been received (unless one's address had changed) so the normal advice for cases of non disclosure is to negotiate with the prosecutor before the case is heard that you will plead guilty to the original offence if they drop the offence of non disclosure. In court you then plead for the lowest possible penalty.

If you have been convicted of an offence in your absence you could possibly appeal it, but you must consider if it is worth the effort & stress
