It's not required that you have an attorney to get divorced in the state of Florida, it is highly recommended. There are a lot of very technical issues that happen when you get divorced, particularly with the division of real property, retirement accounts, bank accounts, and particularly with issues dealing with children, including the development of a parenting plan and ensuring child support is calculated correctly.
You want to make sure that all that paperwork is done correctly and that it's going to be done in a way that's going to protect your rights and your interests. It's much harder to get those things changed later on if they were done incorrectly the first time. It's always in your best interest to hire an experienced family law attorney that can guide you through the process to make sure your rights and interests are protected.
