The total cost to complete the case varies depending on the complexity of the issues and cooperation from each side. For example, if a business is owned by one or both parties, will a valuation have to be performed by an outside expert? Will the marital residence need an appraisal? Costs for experts and fees for attorneys vary. Are both parties forthcoming with providing requested information, or is a formal discovery process necessary? Similarly, can the parties agree to certain issues, or will the attorney have to prepare for court hearings? These are some of the factors that affect the costs of divorce.
