Yes, it is essential that you tell your divorce lawyer everything. Your divorce lawyer is the person on your side fighting for you and it’s important for them to have all relevant information about your marriage. You might not want to share sensitive information, including if there’s an affair or abuse involved—by either party—but they need to know the facts to adequately prepare. The last thing your divorce attorney needs is scandalous information to pop up that they couldn’t prepare a defense for and that hurts your position. So, as difficult as it might be, be sure to share everything—the good and the bad—with your divorce attorney.
