The looming cost of a divorce may seem scary to consider when you are ready to start your official divorce proceedings. When you file your initial petition for the dissolution of your marriage, it will cost over $400. If motions or extensions need to be filed along the way, like a motion to change a child support agreement, the court might require a fee, as well. If you work with an experienced divorce attorney, they will also charge either a flat rate or an hourly fee, depending on how difficult your case is. Overall, you can expect to spend several thousand dollars to finalize your divorce. The peace of mind that you made the best decisions for your family and their future is, however, priceless.
