Child Support in Florida

Your child’s financial stability should not be a casualty of divorce. Florida law ensures both parents remain responsible, but how much you pay or receive depends on getting the calculation right. Child support is often established during a dissolution case, but the same rules can also come up in paternity and post-judgment matters.

Florida uses the Income Shares Model under Statute § 61.30, factoring in both parents’ income, overnights, and costs like healthcare and childcare. Even small changes in income or time-sharing can significantly affect support amounts. Our Florida child support lawyers help parents establish, modify, and enforce support across South Florida.

How Child Support Is Calculated in Florida

Florida’s Income Shares Model is designed to ensure children receive the same proportion of parental income they would have enjoyed if the family remained intact. The calculation follows a structured statutory formula: 

Determine each parent’s gross income

This includes wages, salary, bonuses, commissions, business income, rental income, dividends, pensions, and most other recurring sources

• Subtract allowable deductions: Federal and state taxes, Social Security, Medicare, health insurance premiums paid for the parent, and mandatory union dues or retirement contributions.
• Combine both parents’ net incomes: This total determines the base child support obligation from Florida’s statutory guideline table.
• Calculate each parent’s percentage share: If you earn 60% of the combined income, you’re responsible for 60% of the support obligation.
• Add childcare and health insurance costs: Work-related daycare expenses and the child’s health insurance premiums are added to the base amount and allocated proportionally.
• Apply the time-sharing adjustment: If a parent has 20% or more overnights (73+ nights per year), the substantial time-sharing formula reduces the paying parent’s obligation.

Every family’s financial situation is unique. Our child support calculator provides an estimate, but working with an experienced attorney ensures all factors are properly considered.

Guideline Deviations

Courts may deviate from the guideline amount under § 61.30(1)(a). Judges can deviate up to 5% without written findings. Greater deviations require written justification based on factors such as:

• Extraordinary medical, psychological, or educational needs of the child
• Independent income of the child
• Seasonal variations in a parent’s income
• Age of the child and specific needs at different stages
• Assets available to meet the child’s needs

Who Pays Child Support in Florida

The parent with fewer overnights is typically the “obligor” (paying parent). However, because Florida uses the income shares model, even parents with equal time-sharing may owe support if there is a significant income disparity. The higher earner often pays the difference to equalize what the child experiences in each household.

Child support is the right of the child, not the parent. This legal distinction matters: parents cannot simply agree to waive support. Any arrangement must be approved by the court, which will independently determine whether it serves the child’s best interests.

How Long Does Child Support Last?

Under Florida Statutes § 61.13 and § 743.07, child support typically terminates when the child turns 18. However, several important exceptions apply:

• High school extension: If the child is 18 but still enrolled in high school with a reasonable expectation of graduating before turning 19, support must continue until graduation.
• Children with disabilities: For children with physical or mental disabilities established before the age of majority, the court can order support to continue indefinitely.
• Early termination events: Support ends automatically upon the child’s marriage, military enlistment, legal emancipation, or death.

Important: Payments deducted from your paycheck do not stop automatically when your child turns 18. You may need to file a formal motion to terminate the Income Deduction Order and prevent overpayment. Simply stopping payment without court approval can trigger enforcement actions against you.

Special Situations in Child Support Cases

Self-Employed Parents

Calculating income for business owners presents unique challenges. Florida courts examine “gross receipts minus ordinary and necessary business expenses.” Personal expenses run through the business, excessive depreciation, cash transactions, and unreported income can all affect the calculation.

We help clients navigate these cases to assist in presenting accurate financial information, whether you’re seeking appropriate support or defending against inflated claims.

High-Income Cases

When the combined monthly net income exceeds $15,000, Florida’s guideline table no longer provides specific amounts. The court applies a percentage to the excess income based on the number of children. These cases often involve additional considerations like private school tuition, extracurricular activities, summer camps, and maintaining the child’s pre-divorce standard of living.

Substantial Time-Sharing Adjustments

If a parent has the child for at least 20% of overnights (73 or more nights per year), Florida applies a “substantial sharing” formula that typically reduces the child support obligation. This recognizes that the parent is already contributing directly to the child’s costs during their parenting time. Disputes over overnight calculations often intersect with parenting plan negotiations.

Modifying Child Support in Florida

Life changes, and Florida law provides a pathway to adjust support when circumstances warrant. Under § 61.30(1)(b), you can request a modification if there is a substantial, permanent, and involuntary change in circumstances. The change must typically result in at least a 15% or $50 difference from the current support amount. If your circumstances have changed, you may be able to seek a child support modification.

Common grounds for modification include:

• Job loss or significant income reduction (involuntary)
• Substantial income increase by either parent
• Changes in the child’s healthcare or educational costs
• Changes in the time-sharing arrangement
• Emancipation of one child when multiple children are covered

Retroactive Child Support

In some cases, a parent may be entitled to child support for a period before the court order was entered. Florida law allows courts to award retroactive support, but there are important limitations to consider.

When Retroactive Support Applies

Retroactive support is most commonly sought in paternity cases where the parents were never married, and no support order existed. Once paternity is established, the court may order the non-custodial parent to pay support retroactive to the date of the child’s birth or the date the parent was placed on notice of the paternity claim.

In divorce cases, retroactive support may be awarded back to the date the petition was filed if one parent was not contributing financially during the litigation period.

Limitations

Florida courts generally limit retroactive support to a maximum of 24 months before the filing of the petition. The court considers factors such as the paying parent’s knowledge of the child, their ability to pay during the retroactive period, and any informal support that was provided.

Arrears and Enforcement

Retroactive support creates an immediate arrearage (past-due balance) that must be paid in addition to ongoing monthly support. These arrears are enforceable through all standard enforcement mechanisms, including wage garnishment, license suspension, and contempt proceedings.

If you believe you are owed retroactive support, or if you are facing a retroactive support claim, our attorneys can help you understand your rights and build an effective case.

Enforcing Child Support Orders

Florida takes child support enforcement seriously. The Florida Department of Revenue (DOR) has broad authority to collect unpaid support, and, critically, child support obligations are generally non-dischargeable in bankruptcy. Enforcement remedies can include wage garnishment, license suspension, passport denial, and contempt proceedings.

Enforcement mechanisms available under Florida law include:

• Income Deduction Orders (IDO): Wages garnished directly from paychecks before the obligor ever sees the money
• Interception of funds: Federal and state tax refunds, bank accounts, and lottery winnings can be seized
• License suspension: Driver’s licenses, professional licenses, and recreational licenses (hunting, fishing, boating) can be suspended under § 61.13016 until a payment agreement is reached
• Passport denial: Arrears exceeding $2,500 can result in passport denial or revocation
• Contempt and incarceration: In severe cases of willful non-payment, courts can issue a Writ of Bodily Attachment, essentially an arrest warrant, holding the parent in jail until a “purge amount” is paid

If your co-parent is not paying court-ordered support, get in touch with our attorneys to see your options for compelling compliance.

Protecting Yourself When Paying Support

We strongly advise against making direct payments to the other parent – cash, Venmo, Zelle, or personal checks – unless your court order explicitly allows it. Payments made outside the approved method, like “gifts,” may not always be credited unless properly documented.

To protect yourself, payments should go through the Florida State Disbursement Unit (SDU) or via an Income Deduction Order. This creates an official government record of every dollar paid, eliminating “he said, she said” disputes over missed payments.

Common Mistakes in Florida Child Support Cases

1. Paying Directly Without Documentation

Cash or app-based payments without court approval can be treated as gifts. If you cannot prove payments through official records, you may be ordered to pay again. Always route payments through the SDU or ensure you have explicit court authorization for alternative methods.

2. Hiding Income or Underreporting Earnings

Florida courts have tools to uncover hidden income, like tax returns, bank records, lifestyle analysis, subpoenas to employers and financial institutions. If caught underreporting, you face potential back support calculated at the correct amount, penalties, and attorney’s fees.

3. Stopping Payments Without a Court Order

Even if your child turns 18, moves out, or circumstances change dramatically, you cannot unilaterally stop paying. Arrears continue to accrue at the ordered amount until a judge officially modifies or terminates the order. File a motion—don’t just stop.

4. Delaying Modification Requests

If you lose your job or experience a significant income drop, arrears accrue at the original amount from day one—not from when you file for modification. Act promptly when circumstances change to minimize the financial damage.

Common Misconceptions About Florida Child Support

Myth: If I have 50/50 custody, I won’t pay support.

Reality: Time-sharing affects the calculation, but income is the primary driver. If you earn significantly more than your co-parent, you may still owe support even with perfectly equal overnights.

Myth: Only mothers receive child support.

Reality: Support is based entirely on income and time-sharing, not gender. Fathers receive support when the calculation favors them. We represent both mothers and fathers in support matters.

Myth: Child support automatically covers college expenses.

Reality: Florida child support terminates at 18 (or 19 if still in high school). College expenses are not included in the statutory calculation. If you want the other parent to contribute to higher education, it must be negotiated as part of your settlement agreement.

Myth: I can withhold visitation if support isn’t paid.

Reality: Time-sharing and child support are legally separate issues in Florida. Withholding your child because of unpaid support can result in contempt charges against you and damage your credibility in any ongoing custody proceedings. The proper remedy is to seek enforcement through the court or DOR.
