Child Support in Columbia County, Florida

Columbia County residents have two ways to handle child support. One is to apply through the Florida Department of Revenue Child Support Program for an administrative order. The other is to ask the Third Judicial Circuit's family division, based at the courthouse in Lake City, to set support inside a divorce, paternity, or parenting case. Lake City sits where Interstate 10 meets Interstate 75, making Columbia County a transportation hub for the Third Circuit. That circuit also covers Dixie, Hamilton, Lafayette, Madison, Suwannee, and Taylor counties, so its family court administration and mediation program serve all seven, not just Columbia.

Florida uses one statewide child support formula: an income shares model set out in Florida Statute 61.30 and calculated on Form 12.902(e), the Child Support Guidelines Worksheet. That worksheet draws its numbers from a Family Law Financial Affidavit: the short Form 12.902(b) for anyone earning under $50,000 a year, or the long Form 12.902(c) for $50,000 and up. Both parents usually file an affidavit, and the finished worksheet lands in the court file whether the Department of Revenue opened the case or a parent filed it directly.

Plan on $408 for a dissolution filing. Support-only cases filed under Form 12.904 without a divorce may cost a different amount; ask the clerk to confirm. You can file electronically through the Florida Courts E-Filing Portal at myflcourtaccess.com, which covers every circuit including the Third, or in person at the clerk's office in Lake City. If you cannot afford the fee, ask the clerk to waive it with an Application for Determination of Civil Indigent Status under Fla. Stat. 57.082.

The Columbia County clerk's site has no dedicated self-help portal. Its Divorce page links out to a parenting-course vendor and the Florida Bar instead of hosting its own self-help center or forms page. flcourts.gov hosts the free statewide approved forms, and floridalawhelp.org covers the basics of representing yourself. Enforcement steps such as income withholding, license suspension, or locating a non-paying parent go through the Department of Revenue Child Support Program, not the clerk's office. Call 850-488-KIDS (5437) or use the eServices portal at childsupport.floridarevenue.com.

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 Columbia 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 Columbia County, FL

Child support in Columbia County, FL is handled through the Third Judicial Circuit Court of Florida, Columbia 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 Columbia County, FL

The Columbia County Courthouse at 173 NE Hernando Avenue, Lake City, FL 32055 handles family law filings for Columbia County. The Third Circuit's own materials do not say whether Columbia County still uses a general magistrate or a separate child support hearing officer for these cases, so check with the clerk once the hearing is set.

Florida circuits commonly order mediation before setting a contested child support hearing, and many let parties appear remotely by Zoom or phone at the judge's discretion. Columbia County does not publish a local policy on this, so ask the clerk or the assigned judicial assistant which rule applies to your case.

The Department of Revenue does not publish a separate local Child Support address for Columbia County; its contact page sends everyone, regardless of county, to the same statewide number, 850-488-KIDS, and the eServices portal. A Supplemental Petition for Modification of Child Support, Form 12.905(b), goes in the same county where the original order was entered, not automatically wherever a parent later moves. Modification generally requires a substantial change in circumstances under Fla. Stat. 61.30.
