A plain-language guide to child support in Osceola County, FL, from Florida's statewide guideline formula to the forms you file at the Ninth Judicial Circuit Court of Florida, Osceola County and how to prepare your paperwork without hiring an attorney.

Osceola County hears child support cases at the Jon B. Morgan Osceola County Courthouse in Kissimmee. The Ninth Judicial Circuit assigns a dedicated child support hearing officer to Office 3100 there. Most new cases start with the Florida Department of Revenue Child Support Program, not a courthouse filing.
Ninth Circuit hearing officers handle Title IV-D matters on DOR's behalf. That covers paternity, setting a support amount, enforcement, medical support, modification, and interstate cases under the Uniform Interstate Family Support Act. A parent opens a case with DOR by phone or online. Any hearing that follows takes place at Office 3100 in the Kissimmee courthouse.
Child support tied to a parent's own divorce or paternity case, rather than one DOR opened, usually goes before a family law magistrate instead. Both paths use the same statewide guidelines worksheet and financial affidavit to calculate the amount.
To modify an order, a parent files a Supplemental Petition to Modify, Form 12.905(b), and shows a substantial change in circumstances. Once an order is entered, collection runs through the Florida State Disbursement Unit, not the Osceola Clerk.
Florida sets child support with a statewide income shares guideline (Fla. Stat. 61.30) that applies the same way in Osceola County, FL as everywhere else. The guideline combines:
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.
Child support in Osceola County, FL is handled through the Ninth Judicial Circuit Court of Florida, Osceola 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:
Because courthouse and local agency office details change over time, confirm current details using the Florida court clerk directory:
Find the Osceola County, FL Clerk of Court (Florida court clerk directory)
The Osceola Clerk's website blocks automated checks, so this guide can't confirm office hours or self-help details straight from the source. Call the clerk's family division directly, or check osceolaclerk.com yourself, before you visit.
Osceola shares its circuit child support contact number, 407-836-2287, with the Orange County office. Both fall under the Ninth Judicial Circuit's domestic relations division. Ask which office and room number applies to your case: 3100 in Kissimmee or 540 in Orlando.
The Osceola Clerk's published fee schedule splits the standard dissolution fee into two parts: $397.50 collected at filing and $10.50 collected at final judgment. Together they total the statewide $408 figure, but this is not a child support filing fee. A supplemental petition to modify support carries its own separate cost; this guide could not confirm that amount, so check with the clerk directly.

Ninth Circuit Self-Help / Osceola Clerk (https://ninthcircuit.org/child-support) can help with procedure and paperwork. osceolaclerk.com returned an access error to every automated check, so its family self-help page could not be independently verified for this guide. The Ninth Circuit's own child support and hearing officer pages, which do not sit behind the same block, were used instead.

If the Department of Revenue opens your case, you apply by phone at 850-488-KIDS (5437) or online, not by filing at the courthouse. If your child support issue comes from your own divorce or paternity case, file at the Jon B. Morgan Osceola County Courthouse, 2 Courthouse Square in Kissimmee.
DOR-initiated Title IV-D cases go before the circuit's child support hearing officer at Office 3100 in the Kissimmee courthouse, phone 407-836-2287. Child support outside that DOR track, tied to a parent's own case, usually goes before a family law magistrate instead.
File a Supplemental Petition to Modify, Form 12.905(b), and show a substantial change in circumstances since the last order, such as a significant income change. If DOR administers your case, ask about its periodic administrative review process instead of filing new paperwork.
Every case needs the Child Support Guidelines Worksheet, Form 12.902(e), calculated under Florida Statute 61.30. You also need a Family Law Financial Affidavit: the short Form 12.902(b) if you earn under $50,000 a year, or the long Form 12.902(c) if you earn more.
Opening a case through the Department of Revenue has no signup fee. A privately filed Supplemental Petition to Modify carries its own clerk fee; this guide could not confirm the current amount, so check with the Osceola Clerk's family filing desk.
Payments go through the Florida State Disbursement Unit, not the Osceola Clerk. Pay by electronic check, card through Smart ePay, cash at a Walmart MoneyCenter, or by mail, and check your history through DOR eServices or PayKidz.
