Be sure to discuss with your defence lawyers the best strategy to use for your plea. Likely, it will cover any or all of the following (amongst many other things):
Presentation of the case
Documents that you need to provide to your lawyers
Mental health professionals who will provide reports
Whether the mental health professionals will attend before the court to give evidence
Everything needs to be thoroughly checked during trial preparation – character references, witnesses, the questions that are likely to be asked to witnesses, etc. You and your defence lawyers, and the other people involved in your case defence, need to be oriented about the processes involved.
You need to know and understand the things that will be presented on your behalf and their purpose.
