Before we dive into the forms, it's crucial to understand that Florida uses a specific formula to calculate child support, based on each parent's income and the number of overnights the child spends with each parent. The Florida Department of Revenue provides an online child support calculator to help you estimate the amount.

Initiating a Child Support Case

To begin a child support case in Florida, you'll need to file a petition with the court. The specific form you'll use depends on your situation.

If you're married to the other parent and seeking support, you'll file a Petition for Dissolution of Marriage with Minor Children (Form 12.901(a)). If you're not married, you'll file a Petition to Establish Paternity and Support (Form 12.901(b)). Both forms can be found on the Florida Courts website.

To calculate child support, the court needs detailed income information from both parents. You'll need to complete and file a Financial Affidavit (Form 12.902(e)). This form requires you to list your gross income, deductions, and any additional sources of income.

You'll also need to provide proof of your income, such as pay stubs, tax returns, or a letter from your employer. If you're self-employed, you'll need to provide additional documentation, like business records or profit and loss statements.

Once the court has your income information, it will use the Florida Child Support Guidelines to calculate the amount of child support. The guidelines consider each parent's income, the number of overnights the child spends with each parent, and other factors, like health insurance costs and daycare expenses.

You can use the online child support calculator to estimate the amount of support based on your specific situation. However, the court will make the final determination based on the information provided in your financial affidavit.

Modifying a Child Support Order

Life circumstances change, and sometimes, a child support order needs to be modified. In Florida, you can file a Motion to Modify Child Support (Form 12.913(a)) to request a change in the support amount.

To have a chance of success, you'll need to show the court that there's been a significant, permanent, and involuntary change in circumstances, such as a substantial change in income for either parent, a change in the child's needs, or a change in the amount of time the child spends with each parent.

Income Changes

If you're seeking to modify child support due to a change in income, you'll need to complete and file an updated Financial Affidavit (Form 12.902(e)). You'll also need to provide proof of your new income, just as you did when you initially filed for child support.

If the other parent's income has changed, you can request that the court order them to complete and file an updated Financial Affidavit. If they refuse, you can request that the court impute income to them based on their earning capacity.

Other Changes in Circumstances

If you're seeking to modify child support due to a change in the child's needs, you'll need to provide evidence of the change. For example, if the child has developed a medical condition that requires additional care or expenses, you'll need to provide medical records and an estimate of the additional costs.

If you're seeking to modify child support due to a change in the time-sharing schedule, you'll need to provide evidence of the change in the number of overnights the child spends with each parent. The court may require you to file a proposed parenting plan that reflects the new schedule.

Navigating the child support process in Florida requires attention to detail and a thorough understanding of the necessary forms. If you're unsure about any aspect of the process, it's essential to consult with a family law attorney. They can provide guidance tailored to your specific situation and help ensure that your child's needs are met.
