Child Support in Collier County, Florida

Collier County child support cases are filed and heard at the Collier County Courthouse in Naples. The courthouse sits in the 20th Judicial Circuit, which also covers Charlotte, Glades, Hendry, and Lee counties.

Most new cases start with the Florida Department of Revenue Child Support Program, not a courthouse filing. A parent applies by phone or online, and DOR establishes paternity, sets the support amount, and pursues enforcement. A hearing on that case then goes before one of the circuit's general magistrates or hearing officers.

The 20th Circuit does not keep a Collier-specific list. It publishes one shared roster of magistrates and hearing officers covering all five counties. A parent with an upcoming hearing should confirm the official assigned to their case with the Collier Clerk's family filing desk.

Every case, whether DOR opens it or a parent files privately, uses the same statewide guidelines worksheet and financial affidavit to calculate support. Modifying an order means filing a Supplemental Petition to Modify, Form 12.905(b), and showing a substantial change in circumstances.

How child support is calculated in Florida

Florida sets child support with a statewide income shares guideline (Fla. Stat. 61.30) that applies the same way in Collier County, FL as everywhere else. The guideline combines:

1. Both parents' net incomes, combined into one child support obligation.
2. The number of overnights each parent has with the child (the time-sharing schedule).

The guideline result is presumed correct, and the parties complete a Child Support Guidelines Worksheet along with a Financial Affidavit (Florida Supreme Court approved family law form 12.902(b) or 12.902(c)) so the court can calculate the amount.

Where child support cases are handled in Collier County, FL

Child support in Collier County, FL is handled through the Twentieth Judicial Circuit Court of Florida, Collier County, and, for enforcement and establishment cases that do not involve a private attorney, the Florida Department of Revenue Child Support Program, which can open a case at no cost to the parents. There are two common paths:

1. A parent requests support inside a dissolution, paternity, or existing family case by motion, with a Financial Affidavit.
2. The Department of Revenue Child Support Program opens an administrative or court case to establish, collect, and enforce support.

Local notes for Collier County, FL

For family law fee questions, call the Collier Clerk's Self-Help Center directly at (239) 252-2745 or email CollierClerk@CollierClerk.com. That call is worth making before a trip to the Naples courthouse.

Collier's published fee schedule lists several family-adjacent charges beyond the standard dissolution fee: a $3.50 oath administration fee per person, a $10.00 summons fee, and a $392.50 fee for a counter-petition for dissolution filed in other domestic relations cases. None of these is the same as a private child support modification filing fee. The clerk's site does not list that fee separately, so call the family filing desk to confirm it before you file.

The 20th Circuit's hearing officer and magistrate roster is not broken down by county. A Collier parent should ask the clerk's family filing desk directly which official is assigned to their case, rather than guess from the circuit-wide list alone.

Collier also has its own court schedule page through the 20th Circuit, listing dockets by division. Check it before a scheduled hearing to confirm the correct courtroom and time at the Naples courthouse, since the building houses family, civil, and criminal divisions together.
