Unfortunately, not all divorce cases can be resolved in a quick and amicable fashion. High conflict may arise for a variety of reasons, most commonly due to fault issues (adultery, domestic violence, substance abuse, etc.), child custody disputes, high asset cases, etc.
An experienced divorce and family law lawyer will not only be your advocate, but should counsel you and have a plan to reduce the degree of conflict and keep the case progressing forward. You and your lawyer should communicate frequently about your primary goals, how to achieve them, and not get easily side-tracked by engaging in matters not directly related to achieving those ulimate goals.
Outside resources can also be extremely helpful in reducing conflict, including family counseling, personal counseling, financial or accounting experts, as well as early-stage mediation. Your lawyer should be able to offer recommendations to you and arrange for you to meet with experts so you can understand how they can help you to acheive your goals.
