Co-Parenting Expense Rules in Florida (2026)

How Florida Handles Shared Child Expenses

Florida uses an income-shares model to determine how child-related costs are divided after separation or divorce. The governing statute is Florida Statute 61.30, which lays out the child support guidelines worksheet that judges and parents use statewide.

The idea behind the income-shares model is straightforward: the state estimates what a family with your combined income would typically spend on raising children, then splits that amount between both parents based on each parent's percentage of the total income. The parent who has less overnight time with the child generally pays the other parent the difference as child support.

This model recognizes that both parents have a financial obligation to their children, regardless of how custody time is divided. Florida courts rely heavily on the guidelines worksheet, and deviations require specific written findings explaining why the guideline amount is unjust or inappropriate.

What Florida Child Support Covers

The guideline child support amount calculated under Statute 61.30 is intended to cover the child's ordinary recurring needs: housing, food, clothing, basic transportation, and everyday living expenses. The calculation starts with a schedule of monthly amounts based on combined parental income and the number of children.

Four main factors drive the guideline calculation:

• Combined monthly net income of both parents (gross income minus allowable deductions like taxes, mandatory union dues, and support payments for other children)
• Number of children shared between the parents
• Health insurance premiums attributable to the child (added into the calculation)
• Childcare costs necessary for employment or job training (added into the calculation after adjusting for tax credits)

The guideline amount from the statutory table is a baseline. Health insurance and childcare costs are added on top, then the total is split proportionally between parents based on their income shares. If you are paying for everyday expenses like school lunches, clothing, and haircuts during your parenting time, those are generally considered covered by the guideline support amount.

The 2023 Florida Child Support Reform (SB 1416)

Florida enacted Senate Bill 1416 in 2023, which took effect on July 1, 2023. This was the first major overhaul of the child support guidelines in over a decade, and it changed several aspects of how expenses are calculated and shared.

Updated Income Tables

SB 1416 updated the statutory child support schedule — the table that maps combined parental income and number of children to a base support amount. The previous tables had not been updated since 2014, and the new tables reflect current costs of raising children. In many cases, the updated tables resulted in modest changes (both increases and decreases) to guideline amounts, depending on income level and number of children.

Changes to Overnight Calculations

Before the 2023 reform, Florida used a 20% overnight threshold as a bright-line rule. If the non-custodial parent had the child for fewer than 73 overnights per year (20%), the standard calculation applied with no adjustment. Once the parent crossed 73 overnights, a different formula kicked in that significantly reduced the support obligation.

This created an all-or-nothing cliff: one extra overnight could swing support amounts by hundreds of dollars per month. The system incentivized litigation over overnight counts.

SB 1416 replaced this with a more gradual approach. The new formula uses a sliding scale that adjusts more smoothly as overnight time increases. While the exact calculations still involve the statutory worksheet, the result is that small changes in parenting time no longer produce dramatic swings in support amounts. This reduces conflict over individual overnights and better reflects the actual cost-sharing between households.

Impact on Expense Sharing

The reform did not fundamentally change the income-shares model itself, but the updated tables and smoother overnight adjustments mean that many existing child support orders may no longer match the current guidelines. Either parent can file a petition to modify if the new guidelines would produce a result that differs from the existing order by at least 15% or $50, whichever is greater (per Statute 61.30(1)(a)).

Health Care Cost Splitting

Health care is one of the most common sources of expense disputes between Florida co-parents. The statute addresses it in several layers.

Health Insurance Premiums

Under Statute 61.30(8), the court must order health insurance coverage for the child if it is available at a reasonable cost through either parent's employer or other group plan. The cost of the child's portion of the health insurance premium is added to the basic support amount before the total is split between parents. This means both parents share the insurance cost proportionally based on income, regardless of which parent carries the policy.

Uninsured Medical, Dental, and Prescription Costs

Costs not covered by insurance — co-pays, deductibles, orthodontics, therapy, glasses, prescriptions — are addressed under Statute 61.30(8)(b). These are split between parents in proportion to their respective incomes.

The $250 Threshold

Florida has a specific rule for minor uninsured medical expenses. The first $250 per year in non-covered medical, dental, and prescription costs is typically the responsibility of the obligee (the parent receiving support). Amounts exceeding $250 per year are shared proportionally based on each parent's income percentage.

This threshold exists to avoid constant reimbursement requests for small co-pays and routine expenses. However, the court can adjust or eliminate this threshold based on the circumstances of the case.

Emergency vs. Elective Medical Expenses

Emergency medical treatment does not require advance consent from the other parent. If your child breaks an arm or has an allergic reaction, you get treatment first and handle reimbursement later. Florida courts will not penalize a parent for seeking emergency care without prior agreement.

Elective or non-emergency medical expenses — braces, elective surgery, specialized therapy — are different. While there is no explicit statutory requirement to get the other parent's consent before incurring non-emergency medical costs, failing to consult your co-parent can create problems when you seek reimbursement. Courts look at whether the expense was reasonable and whether the other parent had an opportunity to participate in the decision. Best practice is to notify your co-parent in writing before scheduling elective procedures and give them a reasonable time to respond.

Childcare Costs

Net childcare costs are factored directly into the guideline calculation under Statute 61.30(7). The statute specifies that childcare must be related to employment, job search, or education/training leading to employment. Purely discretionary childcare — hiring a babysitter for a date night, for example — does not qualify.

The childcare amount used in the worksheet is the net cost after any applicable federal tax credits. Both parents share this net cost proportionally based on their income percentages, just like health insurance. The childcare add-on is included in the worksheet before the final support amount is calculated, so it is built into the monthly payment rather than tracked separately.

If childcare costs change (a child ages out of daycare, or a parent changes work schedules), this can be grounds for modifying the support order.

Extracurricular and Education Expenses

This is where Florida law diverges from some other states. Extracurricular activities and private education costs are not automatically included in the child support guidelines and are not mandatory add-ons under Statute 61.30.

Private school tuition, sports league fees, music lessons, dance classes, travel sports, summer enrichment programs — none of these are automatically shared expenses under Florida law. For these costs to be split between parents, you need one of the following:

1. A written agreement between both parents specifying how the expense will be shared. This is the simplest path. An email or text exchange confirming "we'll split soccer league fees 60/40" is enforceable if it is clear and specific.

2. A court order requiring the expense. Courts will consider these factors when deciding whether to order shared extracurricular or education costs:

   • Whether the child participated in the activity before the separation (courts are reluctant to disrupt established activities)
   • The family's standard of living during the marriage
   • The child's demonstrated talent or interest
   • Whether both parents can reasonably afford the expense
   • The child's best interests

If your child was attending private school during the marriage, courts are more likely to order continued sharing of tuition. If one parent wants to enroll the child in a new, expensive activity post-divorce without the other parent's agreement, the enrolling parent will likely bear the full cost unless they obtain a court order.

Practical Calculation Example

Here is a walkthrough of Florida's child support worksheet for a family with one child:

Income:

• Parent A monthly net income: $5,000
• Parent B monthly net income: $3,333
• Combined monthly net income: $8,333

Income shares:

• Parent A's share: $5,000 / $8,333 = 60%
• Parent B's share: $3,333 / $8,333 = 40%

Using the statutory table (Statute 61.30(6)) for one child at $8,333 combined monthly income, assume the base support need is approximately $1,100/month.

Now add health insurance and childcare:

Each parent's share of the total:

If Parent B is the majority-time parent, Parent A would pay $1,140/month in child support (which already includes their share of insurance and childcare). The actual worksheet adjusts further based on overnight percentages using the SB 1416 sliding scale.

Uninsured medical expenses are tracked separately. Suppose the child has $150/month in uninsured costs ($1,800/year). After the custodial parent absorbs the first $250 per year, the remaining $1,550 is split:

This is why tracking medical expenses separately matters. The guideline payment handles insurance and childcare, but uninsured costs require ongoing documentation and reimbursement between parents.

When You Disagree on Expenses

Florida provides a structured process for resolving expense disputes between co-parents.

Mediation First

Florida strongly favors mediation for family law disputes. Under Statute 44.102, most family law matters must go through mediation before a court hearing. Many circuits require mediation as a prerequisite to any motion hearing. Mediation sessions are typically conducted by a Florida Supreme Court Certified Family Mediator, and the cost is shared between the parties (usually $100-$250 per hour each, though low-income parties may qualify for reduced rates through court programs).

Mediation works well for expense disagreements because it allows parents to negotiate specific arrangements — like agreeing to split soccer fees but not private school tuition — that a judge might not have the time or context to craft.

Motion to Modify

If mediation fails or circumstances change significantly, either parent can file a Supplemental Petition for Modification of Child Support. Under Statute 61.30(1)(a), you must demonstrate a substantial change in circumstances that is:

• Significant and material (not temporary or minor)
• Involuntary and permanent (you cannot quit your job to reduce your income)
• Not anticipated at the time of the original order

Common qualifying changes include job loss, significant income increase or decrease, change in the child's needs (medical diagnosis, aging out of childcare), or a material change in overnight time-sharing.

Contempt for Non-Payment

If a court order specifies expense sharing and your co-parent refuses to pay, you can pursue contempt of court proceedings. Civil contempt in Florida requires showing that the other parent had the ability to pay and willfully failed to do so. Consequences can include payment of the arrearage, attorney fees, and in extreme cases, incarceration. This is a serious legal remedy and typically requires an attorney.
