Modify Child Support in Florida

When and How to Change a Support Order

If your financial situation or parenting schedule has changed, Florida law allows you to seek a modification of your child support order. But it must go through the proper legal channels to be enforceable.

When Modification Is Allowed

Substantial Change in Circumstances

Florida courts only allow modifications to child support if there’s been a “substantial change in circumstances” since the original order. That could mean a significant income shift for either parent, changes in a child’s needs (such as new medical expenses), or changes in the time-sharing schedule.



A general rule: the change must result in a difference of at least 15% or $50 per month—whichever is greater—for the court to consider it substantial.


Common Reasons for Modification

Life Changes That Could Justify a New Order

Many life events can justify a support adjustment, such as:

  • Job loss, demotion, or significant drop in income
  • Promotion or substantial raise
  • One parent becomes disabled or retires
  • Changes in child care or health insurance costs
  • A child no longer needs daycare
  • Shift in custody or time-sharing schedule (e.g., from one parent to 50/50)

These changes can trigger either an increase or a decrease in the child support amount, depending on the details.


The Legal Process to Modify Support

Filing in the Same Court as the Original Order

To modify support, a Supplemental Petition for Modification must be filed with the same court that issued the original order. Both parents will be required to submit updated financial affidavits, and supporting documentation will be needed to prove the change.


A hearing may be scheduled where a judge will reapply Florida’s guidelines to your new circumstances. Our firm helps gather, organize, and present the financial data in the strongest possible light for your position.


Retroactivity and Temporary Relief

Timing Matters for Financial Impact

Modifications are not retroactive before the filing date. That means even if your income dropped three months ago, your child support won’t change until the date you filed your petition.



In some urgent situations—like sudden unemployment or medical disability—the court may allow temporary relief while the full case is pending. We can help you petition for temporary modifications if your situation warrants it.


Avoiding Verbal Agreements

Why You Need a Court Order

Even if both parents agree to a new amount informally, that agreement is not legally enforceable unless the court approves it. This means you could be held responsible for the original amount later, even if your ex agreed to a lower payment.



To protect both parties and avoid future disputes, always go through the proper legal process to adjust child support.
