Child Support in Nassau County, Florida

Nassau County child support cases fall under the Fourth Judicial Circuit. You file paperwork with the Clerk of Court's Yulee office at 76347 Veterans Way, the county's main full-service location. This applies whether you want the court to set support for the first time, change an amount already ordered, or enforce payments that have stopped coming.

Two tracks exist, depending on whether a court case is already open. If the parents were never married and no paternity case has been filed, the Florida Department of Revenue Child Support Program can open an administrative case in Nassau County and set support without a lawsuit. When a circuit court case already exists, you file changes in that same case as a Supplemental Petition for Modification of Child Support, Form 12.905(b).

As in every Florida county, the dollar figure comes from the statewide Child Support Guidelines Worksheet, Form 12.902(e). It applies Florida Statute 61.30 to both parents' net income, time-sharing schedule, health insurance costs, and child care expenses. Judges can deviate from that guideline number only for reasons the statute lists. Most Florida child support orders, including this one, also come with an Income Deduction Order under Fla. Stat. 61.1301. That order directs the paying parent's employer to withhold support directly from wages.

Both parents typically file a Family Law Financial Affidavit before a hearing: the long form 12.902(b) if gross annual income is $50,000 or more, or the short form 12.902(c) if it is less. Nassau County shares Fourth Circuit Family Court Services with Clay and Duval counties. Self-represented parties should check in with a case manager before submitting forms.

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 Nassau 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 Nassau County, FL

Child support in Nassau County, FL is handled through the Fourth Judicial Circuit Court of Florida, Nassau 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.
