This is one of the many points at which you want to have a clear strategy that you have discussed with your lawyer.
How is you case going to be presented? Who will be appearing in Court on your behalf? What documents do you need to provide for your lawyers?
This is where all the work that you and your lawyers have done comes together. Character witnesses need to be checked and run through the process. All your reports need to be got together and assessments made about what will be relied on before the Court.
