How Child Support is Calculated and Enforced in Family Court

Child support is one of those topics that almost everyone has heard of, but few people fully understand until they are in a family court waiting for a judge to decide what they must pay or what they should receive. In Florida, child support is mandatory, so parents cannot privately “agree to skip.” In many cases, once parents see the number on a child support order, the emotions can run high, from confusion to frustration. It is common to find a number that one wasn’t expecting. This can lead to questions like “Why am I paying more than someone with more kids?” or “How did the court even come up with this?”

At the Loris Law Group, we understand how confusing this process can be. This guide aims to help you understand how child support is calculated in the simplest way possible, making the entire process feel less overwhelming.

How Child Support is Calculated in Florida

Florida uses the Income Shares Model, as outlined in Florida Statute 61.30, to estimate how much child support should be paid/received. The goal in the entire process is to help the child maintain a stable standard of living. 

Here is a breakdown of how the amount is calculated.

Step 1: Determining Each Parent’s Net Income

The court usually starts by calculating each parent’s monthly net income. Net income is the amount that remains after deducting all allowable expenses from gross income.

Gross income may include the following:

• Salaries and hourly wages

• Commissions or bonuses

• Self-employment income

• Unemployment compensation

• Pension or retirement payments

• Disability or workers’ compensation benefits

Allowable deduction may include:

• Federal, state, and local income taxes

• Mandatory union dues

• Social security and Medicare taxes

• Health insurance premiums

• Court-ordered support paid to other children

  
  

Step 2: Combining Both Parents’ Net Incomes

The court then adds the parents’ net incomes together to get the combined monthly income amount. This figure is then matched to the Florida Child Support Guidelines Table, which shows the basic child support obligations depending on the total combined monthly income and the number of children.

For example, if both parents earn a combined net income of $4,000 and have two children, the guidelines may list a basic obligation of $1,200. But that’s not the final support amount.

Step 3: Assigning Each Parent Their Percentage Share

Next, each parent’s net income is divided by the combined net income of both parents. This gives each parent a percentage share of their responsibility.

If the court determines that parent A earns 60% of the combined income while parent B earns 40%, parent A may be responsible for 60% of the basic obligation and parent B caters for 40%.

Step 4: Factoring in Time-Sharing and Additional Expenses

When calculating child support in Florida, parenting time and any additional expenses are also considered. When a parent has the child for 20% or more of the overnights, that is 73 nights or more per year, the court adjusts the support amount to reflect the costs incurred by the parent during their parenting time. 

Can the Court Deviate From These Guidelines?

Yes. The guidelines provide a starting point in calculating child support, but your unique family circumstances can affect the final figure. Florida courts can deviate up to 5% from the guideline amount without detailed explanations. However, anything beyond 5% must have a written justification.

Some of the most common reasons for deviation may include:

• Extraordinary medical needs

• Educational expenses

• Special needs for disabilities

• Seasonal or fluctuating income

• Any other unique circumstances 

  
  

How Child Support Is Enforced in Florida

Even with a court order in place, some parents may refuse to pay child support. In that case, Florida Law provides tools to enforce compliance. The Florida Department of Revenue (DOR) handles most child support enforcement, although the Clerk’s Office can also issue a Notice of Delinquency upon request.

The main enforcement methods include the following:

1. Wage Garnishment

   
   

This is the most common and straightforward method. The court can order an employer to deduct child support from the paycheck of the parent paying child support before the parent even receives it. If DOR is involved, wage garnishment is automatic.

2. Income Withholding Orders

   
   

This works similarly to wage garnishment but extends to other forms of income, such as bonuses, commissions, pensions, and retirement benefits. The income is typically intercepted at the source.

3. Tax Refund Interception

   
   

If the non-paying parent is owed a federal or state tax refund, DOR can claim that refund and redirect it toward unpaid child support.

4. Property Liens

   
   

A lien can be placed on real estate, vehicles, or other property so that the parent cannot sell or refinance the asset until child support arrears are paid in full.

5. Seizure of Bank Accounts

   
   

With proper authorization from the non-paying parent’s bank, the DOR can seize funds from their bank accounts. This is often used when other enforcement methods have been unsuccessful. 

6. Suspension of Driver’s and Professional Licenses

   
   

If payments fall seriously behind, the state may suspend the non-paying parent’s driver’s license, professional license, recreational license, and even vehicle registrations. The suspension remains in place until compliance or an arrangement is made to pay the child support arrears.

Modification of Child Support

A child support order remains in effect until a child reaches adulthood. However, if one parent can demonstrate a substantial and ongoing change in circumstance, the order can be modified. Some of the reasons for modifying a child support order may include:

• Losing a job

• A significant permanent raise

• A major change in parenting time

• A long-term disability

• New unavoidable medical or childcare expenses

  
  

The parent seeking the change must prove the circumstance and show that it materially affects the existing order.
