How to prepare your case for litigation. There are a few best practices for litigation. I recommend taking a log of events right after the event happens. If you write down what happened, it may be admissible or it could help refresh your recollection. Another thing to is CYA, or Cover Your Avenues. When you have an agreement with someone or a conversation, you should follow that up with an e-mail or letter stating the essence of the conversation. You should also consider consolidating your evidence and compiling a summary of events. Think about witnesses or documents which prove your case.
