Child Support in Florida

Florida courts use a statutory formula to determine how much each parent owes toward a child’s financial support. Because the support calculation is directly tied to child custody and timesharing arrangements, both issues are commonly addressed together in the same proceeding.

Florida’s Child Support Statute: §61.30

Child support in Florida is governed by §61.30, Florida Statutes, which establishes an Income Shares Model. The premise is straightforward: the court estimates how much both parents would have spent on the child had the household remained intact, then divides that obligation between them in proportion to their respective net incomes.

The guidelines apply across all proceeding types — divorce cases, paternity actions, and standalone support petitions. Courts are required to follow them and must document on the record any basis for departing from them.

Working with Florida child support attorneys ensures that income is accurately documented and that the final order reflects your actual financial situation rather than a calculation based on incomplete or misrepresented figures.

How Child Support Is Calculated Under §61.30

Each Parent’s Net Monthly Income

Under §61.30(2), income is defined broadly — wages, salary, bonuses, commissions, self-employment income, rental income, retirement benefits, and most other recurring sources of revenue. From that gross figure, the statute allows specific deductions before arriving at net income:

• Federal, state, and local income taxes
• FICA and Medicare contributions
• Mandatory union dues and retirement contributions
• Health insurance premiums paid by the parent for themselves (not the child)
• Court-ordered support obligations from prior cases

The Combined Income and Guideline Schedule

The court adds both parents’ net monthly incomes together and applies the schedule in §61.30(6) to identify the minimum support obligation for the number of children covered. That total is then split between the parents in proportion to each parent’s share of the combined figure — so a parent earning 60 percent of the combined income bears 60 percent of the baseline obligation.

Adjustments for Child-Specific Expenses

Three categories of expense are added to the base amount and allocated between parents by income share:

• Health insurance premiums paid on behalf of the child
• Childcare costs related to employment, education, or job seeking
• Extraordinary medical, dental, or other court-approved expenses

These are not split equally — they follow the same income-proportionate formula as the baseline obligation.

How Parenting Time Affects the Support Amount

Under §61.30(11)(b), once the minority-time parent reaches at least 73 overnights per year — the statutory threshold for “substantial amount of time,” equivalent to 20 percent of the year — the court is required to apply a timesharing adjustment to the support amount. Below 73 overnights, the standard guideline calculation applies without adjustment.

Once that threshold is crossed, the formula changes materially. Because maintaining two separate households for the child costs more overall, the base support obligation is increased by a factor of 1.5 before being divided. That adjusted total is then apportioned based on each parent’s income share and further weighted by the exact percentage of overnights each parent exercises. The overnight count matters precisely — 72 nights and 73 nights produce meaningfully different financial outcomes under the formula.

The relationship between timesharing, custody, and support means that a modification to the parenting plan can shift the support obligation in either direction. Kalish & Jaggars, PLLC addresses both issues together when representing clients in these proceedings.

When the Guidelines Can Be Adjusted

The guidelines carry presumptive weight — courts must follow them unless a departure is affirmatively justified and documented in the order with written findings. Under §61.30(11), recognized grounds include:

• Extraordinary medical, psychological, or educational expenses for the child
• Independent income of the child
• The child’s seasonal or variable needs
• Significant financial obligations owed to other children outside the current order
• Total available assets of the obligor parent
• Application of the guidelines producing an unjust or inappropriate result in the specific case

A support amount cannot be informally reduced. Any deviation from the guidelines must appear in the court order, supported by written findings.

Child Support in Paternity and Unmarried Parent Cases

A support order requires established legal parentage. Where parents were not married at the time of the child’s birth, parentage must be confirmed either through a Voluntary Acknowledgment of Paternity or a court proceeding — no order for support, custody, or timesharing can be entered until that threshold is met.

Establishing or disputing paternity is therefore the predicate step in any case involving unmarried parents. Without legal parentage on record, neither financial obligations nor parental rights attach through the court.

The Child Support Process in Florida

Filing and Financial Disclosure

A child support action begins with a petition filed in circuit court. Both parents must submit a Financial Affidavit (Florida Family Law Form 12.902) — a sworn disclosure of income, expenses, assets, and liabilities. The accuracy of that document drives the outcome; incomplete or misrepresented figures can result in sanctions and skew the final order against the party responsible for the error.

When child support arises within Florida divorce proceedings, it is resolved as part of the final judgment of dissolution rather than in a separate action.

Agreement or Court Determination

Parents may reach a negotiated agreement on support, but it requires court approval before it is enforceable. The court reviews agreed orders to confirm guideline compliance or that any deviation is properly documented. Where the parties cannot agree, the court holds an evidentiary hearing and issues a ruling based on the financial affidavits and other evidence in the record.

Payment Through the State Disbursement Unit

All child support payments must be processed through the Florida State Disbursement Unit rather than exchanged directly between parents. Every payment is logged, creating an official government record that protects both parties in any future enforcement or modification proceeding.

Modifying an Existing Child Support Order

Orders do not adjust automatically when circumstances change. To modify support, a parent must demonstrate a substantial, and material change in circumstances since the original order was entered — and under §61.30(1)(b), the recalculated guideline amount must differ from the current order by at least 15 percent or $50, whichever is greater. A modest income change that falls below that mathematical threshold will not meet the standard, regardless of how significant it feels.

Qualifying changes that courts commonly recognize include:

• A significant increase or decrease in either parent’s net income
• A substantial change in the child’s healthcare or childcare costs
• A material modification to the parenting time schedule
• A child reaching the age of majority in a multi-child support order

Payments cannot be reduced unilaterally while a modification petition is pending. Unpaid support accrues as arrears throughout, and any modification only takes effect from the date the petition was filed — not the date circumstances actually changed. If your situation may meet the statutory threshold, you can speak with a child support attorney to evaluate whether a petition is warranted.

Child Support Enforcement in Florida

When a parent fails to pay, the Florida Department of Revenue’s Child Support Program has broad authority to act — and can pursue multiple remedies at the same time. Available tools under Florida law include:

• Income deduction orders (wage garnishment), which are mandatory in most cases
• Driver’s license and professional or occupational license suspension
• Passport denial or revocation through the federal Office of Child Support Services
• Contempt of court proceedings, which can include incarceration
• Liens on real property and financial accounts
• Interception of federal and state tax refunds

Arrears accumulate without a statute of limitations, cannot be discharged in bankruptcy, and accrue interest under state law.
