Modifications Actions

Florida Modifications Actions Overview

Basic Requirements for Changing Child Support

If there is a prior court order in place that requires child support, a parent may file for modification any time there is a “substantial change in circumstances.” The substantial change may consist of a change in income for either parent. It may also consist of a change in the overnight parenting pattern exercised by either parent. The Florida child support statutes allow a modification petition anytime the petition would result in a change in support of at least 15% or $50 (whichever is greater).

Change in Income

The most common reason for a change in child support is a change in income. The change can be upward or downward and may involve either the parent paying child support, or the parent receiving child support. There is no absolute amount the income must change before filing for modification. But whatever the change, the revised incomes must result in the child support amount changing by at least 15% or $50. For example: if child support is currently $1000/month, the new calculated support must be either higher than $1150/month, or lower than $850/month. Once the proper threshold is reached, the person desiring to change child support can file a Supplemental Petition to Modify Child Support. You should be aware that a supplemental petition is similar to the original case and is not a quick procedure.

Change in Parenting Time

Modification of child support in Florida may also be supported by a substantial change in the pattern of parenting time. A recent new child support law has strengthened the ability to modify child support based on parenting patterns. Previously, many courts looked at the overnight parenting split as spelled out in the Parenting Plan attached to the last final judgment. The recent change authorizes courts to calculate child support according to the “actual” parenting pattern – as currently exercised by both parents.

In other words, the parenting plan may detail one parent as getting 265 overnights with the kids and the other parent getting 100 overnights with the kids. Child support was most likely calculated based on that exact split. But if the history of the overnight pattern shows the actual split at 300 overnights for one parent, the courts are now allowed to recalculate child support based on the new pattern – despite what the parenting plan calls for.

A technicality in Florida child support law says that child support will vary by each additional overnight only if the “minority parent” has at least 20% of the overnights. In other words, if the parenting plan calls for one parent to have under 20% (73 overnights) and the real-world pattern results in a figure that is still under 20%, then child support would not vary even if the amount of overnights vary.

Change in Expenses

Certain changes in child related expenses could justify changes in child support. The types of expenses that can justify a change in child support are very specific and limited. A couple of the more common changes:

Daycare When daycare expenses have been incorporated into child support, any change in daycare can serve as a reason to modify support. Or if one parent experiences trouble sharing the cost of needed-daycare, they can address that problem by asking for the cost to be included in child support. An important requirement is for the daycare to be related to employment needs. Daycare expenses for a stay at home parent do not qualify under this definition.

Alimony A frequent situation is where temporary or defined-term alimony ends. The additional income freed up when alimony terminates may be considered an increase or decrease in income. That increase or decrease can support a change in child support. Alimony and child support are always interactive issues. More alimony = less child support and visa versa.

Other child support orders Court ordered child support for children from other marriages are a valid deduction from total income. The support must be court ordered in order for this provision to have effect.

Taxes When payroll taxes drastically change, the resulting net income may call for higher or lower child support. One way that could happen is when a parent moves to an area that has state and/or city imposed payroll taxes. Those taxes may drastically change the net income figure that would be used in the child support calculation. One parent could be affected by state and local taxes in another state – even though the case may be in Florida.

Health Insurance for Child Most Florida child support calculations include the cost of health insurance for the children. Each parent pays for that insurance in a proportion equivalent to his or her net income. There may be a need to file for child support modification when health insurance premiums change. Health insurance would have no effect if the child receives state-provided health coverage.

Health Insurance for Parent Each parent pays for his or her own health insurance. But according to the Florida child support statutes, that payment is a valid deduction from gross income. A drastic change can support a modification case.


Each county has a slightly different procedure for child support modification but the basics tend to be the same. The person desiring a change must file a Supplemental Petition to Modify Child Support and serve the petition on the other spouse. Just like a divorce or paternity case, each side must disclose financial information to the other side. Many court jurisdictions require mediation before going to trial. Depending on the jurisdictions, you may have to conduct your case with a special type of judge, called a Magistrate or a Hearing Officer.

A complication that arises in some cases, depends on whether the Florida Department of Revenue has ever been involved with your case. If so, you are required to be seen by a Child Support Hearing Officer, and the case may involve the participation of the Dept. of Revenue and their appointed attorney. 

Parents that lose their jobs

One frequent situation underlying child support modification cases is where one parent or the other loses their job. The job loss could be involuntary, or purposely arranged for the ultimate goal of lowering child support. Even if the job loss is involuntary, that parent may decide not to seek employment until their child support case is concluded. Either side must present evidence supporting their claim that any unemployment is voluntary versus involuntary. That is an important issue for the court to decide before there is any discussion of support recalculation. 

Modifying past Child Support (Arrears)

In general you cannot change child support arrears. What is owed will stay in place – even after a successful modification case. The technical standard is that modifications will be effective as of the filing date of the Supplemental Petition. That makes it extremely important to immediately file your modification case as soon as something changes.

One exception to the general rule is when children become adults. Many attorneys and many judges believe child support can be retroactively terminated – back to the date the child became an adult. But the best way to address situations when kids become adults is to promptly file your case.

Florida Disbursement Unit

Many people are not big fans of the Florida Disbursement Unit because of the inflexibility and the fact that human beings can be difficult to reach when there are problems. In any child support modification case, it is essential to end up with a direct order to the Florida Disbursement Unit correcting child support arrears, and setting proper amounts going forward. Failure to take care of that step causes frequent problems.
