If you have a friend, neighbor, or another family member that will testify on your behalf, your attorney should want to conduct at least a couple of interviews with your witnesses prior to your family jury trial. It is vital that your lawyer know what your witness will testify to during the trial. Your lawyer's job won't be to create a testimony that the witness can rehearse. Instead, the lawyer should work with the witness to ensure that the way that they are relaying information is clear and easy to understand. The lawyer will work with your witnesses when it comes to appropriate courtroom behavior (including non-verbal cues that people give). Your lawyer may even advise a witness to dress a certain manner in order to be a bit more relatable and even more believable to an impartial jury. At our firm, some witnesses are interviewed more than once so that the lawyer can have more time to get to know the witness and their testimony. Here is a time that some lawyers use to practice a bit, running through questions with your witnesses that the lawyer will likely ask on the day of court. Your witnesses should come off as honest and trustworthy to the jurors.
Additionally, your lawyer will also want to be prepared for the opposing side's lay witnesses, especially if any witnesses will testify against you. Your lawyer should have the ability to think on his or her feet so that only the most appropriate and fitting questions are posed to each witness on your lawyer's cross examination of them. Since the opposing party has already given you and your lawyer a list of the witnesses that they plan to call at trial, most of the time both you and your lawyer can anticipate what testimony the witness will give.
In complex family law cases such as divorces with complex property division or complex custody issues, it may ne necessary to employ an expert. The most common experts used in family law cases are therapists, physicians, and CPAs. Since many jurors will lack the necessary experience or education regarding the division of assets or medical diagnosis or suggested treatment for a child, having a knowledgeable expert witness could make or break a case. Let's imagine that you have separate property that has been commingled with discovery. You'll likely need an expert CPA to do some tracing to trace the origin of assets. Since separate property won't be divided in a Texas divorce, it is important to have an expert that can not only assess the extent of the separate property claim(s) of either or both parties, but that can also relay the information in an easy-to-understand way to the jury. This is where the rapport of your attorney and the experts used comes in. If your lawyer has a good working relationship with the experts hired, your lawyer can work with them to ensure that the testimony is up to par. If it is not, you can risk having a jury return a verdict that is not in your favor.
On the same note, perhaps you have employed a child psychologist or maybe the court has appointed one. This psychologist's testimony regarding his or her professional opinion will be given great weight in a custody case decided by a jury.
Finally, as a last step to prepare, your lawyer will likely want to gather all of the supporting documentation needed for trial. Typically, experts will supply the party or parties with written reports of their findings. It is your lawyer's job to mark all necessary supporting evidence as exhibits, after providing the opposing side with copies of each report during the discovery phase.
