The cost of divorce differs depending on the situation. The cost of your divorce will be determined by factors such as the complexity of the case as well as if certain things are contested in court. Typically, the more adversarial the divorce, the more it will cost. Besides attorney costs, you may also be responsible for filing fees or a divorce mediator. Large, valuable property or businesses may need to be appraised by a divorce financial analyst, which will be an additional cost for you and the other party.
