This guide should be used at the start of a case. In fact, we try to make it a practice to start our mandatory settlement conference briefs, which may need to be converted to trial briefs, on day one of a divorce or paternity case. Next, for every day of trial expect at least 2-3 days of preparation time. If your trial is set for four days, expect at least 12 full days of preparation time. Why? Discovery must be propounded such as subpoenas, demand for production of documents and special interrogatories to secure documents needed to prove your matter at trial.
