Child Support in Miami, Explained
Child support in Miami follows Florida's statewide Child Support Guidelines. The system is formula-driven — no judge's whim, no attorney's persuasion. Once the inputs are accurate, the number is mostly determined.
That's the good news and the bad news: get your inputs right, and the result is fair. Get them wrong, and you are overpaying — or your child is being under-supported.
The Core Formula
The Inputs That Matter
The Guidelines combine:
- Both parents' gross incomes
- Health insurance costs for the child
- Child care costs
- The number of minor children
- The overnight schedule (who has the child when)
How the Table Works
Florida publishes a Child Support Guidelines table. Your formulas produce a combined monthly obligation based on the parents' total income and the number of children. Each parent's share corresponds to their percentage of total income.
A Simplified Example
Imagine parent A earns $5,000/month and parent B earns $3,000/month. Combined: $8,000. A's share is 62.5%; B's is 37.5%. The table assigns a combined obligation — and each contributes their percentage, adjusted for the overnight split, insurance paid, and child care paid.
This example is illustrative only — your actual case depends on the current chart and your full facts.
What Counts as "Income"
Included Income
Salary, wages, bonuses, commissions, tips, self-employment income (after certain deductions), retirement benefits, and other regular earnings.
The Income Trap
Courts examine self-employment and discretionary deductions carefully. A parent who claims artificially low income (depreciating assets, boosting write-offs) can face "imputed income" — the court assigning income based on earning capacity. Honest reporting is not just ethical; it's cheaper than litigation.
When Income Is Imputed
If a parent quits work voluntarily or works below capacity, the court may impute income at their demonstrated earning capacity. This protects the child — and protects the paying parent's obligation from being manipulated.
The Overnight Factor — Time-Sharing and Support
Why Overnights Matter
The more overnights a child spends with the higher-earning parent, the lower the net support — the chart accounts for the shared-parenting schedule. A 50/50 split produces a much lower (sometimes zero) net transfer than a 70/30 split.
The 2023 50/50 Presumption
Florida's 2023 reforms created a rebuttable presumption of 50/50 time-sharing when it serves the child. This presumption — when met in practice — changes the child support calculation significantly. If you have 50/50 time-sharing, your support amount should reflect it, not a 70/30 figure.
Add-Ons Are Not Optional
Health Insurance
The parent who provides coverage for the child gets a credit, and the other parent contributes a share of the premium cost.
Child Care
Daycare and before/after-school care that permits work or education are added to the base amount, split by the parents' income shares.
Uncovered Medical
Extraordinary medical expenses not covered by insurance are typically divided proportionally. Document these — they add up quickly.
When the Number Is Wrong
Modification
If your situation changed materially — income, custody, overnight schedule, or costs — Florida allows modification upon a substantial change. The earlier you act, the faster you fix it. See our modifications information.
The 15% Rule of Thumb
A common threshold: income changes of roughly 15% or more may justify review, along with the specific facts. But this rule has nuances — check with your attorney before assuming.
Enforcement — What Happens If It's Not Paid
Florida enforces support through:
- Income deduction orders
- Liens on property and bank accounts
- Tax refund interception
- License suspension (driver's, professional)
- Passport denial
- In extreme cases, contempt of court
Support arrears do not disappear in bankruptcy — they are among the most protected obligations in the law.
