I need to go to court tomorrow to provide evidence in a case where a customer of mine is being charged with fraud. On the subpoena I received it says that i'm "to give evidence concerning the above charge". So i'm sitting here tonight, with my file, going through it and I have no idea what to do/expect. Nobody has contact me since the incident occurred, so I'm just sitting here reading through everything since the incident happened a little over year ago now. Will i be able to just walk in there, with my file and all my information and just be able to answer whatever they ask me? Should I be memorizing the key dates and stuff that apply because I won't be able to have my file for reference? Im just uncomfortable without knowing whats going on, or what to expect. Anyone with any guidance or advice out there from a legal standpoint would be greatly appreciated!
