Fixed costs related to a divorce include the filing fees paid to the court and those paid to have the legal papers served on your spouse. Although they vary from state to state, on average they run between $200 and $500. Variable costs include legal fees for document preparation and legal representation. Fees will vary depending on the complexity of the case. The parties may face additional costs if the court orders mediation of issues that are under dispute or if a financial analyst must intervene to resolve complex property disputes.
