In reply to bednobs' answer - The lawyer obtained my prosecution file from the prosecutor's office. That was it. In all correspondence, I did not instruct them to do anything. Surely the lawyer needs my file to give an estimation of costs before they can proceed with anything. I also asked for likely costs/scale of fees for his work before he obtained my file, to which there was no mention of fees.
In reply to woofgang's answer - I asked him what exactly the charges against me were and what would be the likely costs/scale of fees for his work. He then proposed I meet him the evening before the court date to have a meeting/discuss the case, to which he outlined fees for the meeting and his time in court. He outlined in the email, in bold writing, if I agree to this and would like him to attend court. I declined and thanked him in an email and that was the last time I heard from him.
