How to Contest Child Support in Orange County, Florida

What "contesting" child support means and when you can do it

Contesting child support in Orange County means asking a family court judge to change or cancel a support order that already exists. You do not challenge whether you owe support — you challenge the amount, the duration, or the terms of the order itself. This is different from disputing paternity (whether you are the parent) or appealing a judge's decision after a hearing, though those are separate paths.

You can contest an order if circumstances have changed significantly since the judge issued it — a job loss, a major income increase, custody changes, or a new child born to either parent. You can also contest if the original order was based on incorrect information, such as wrong income figures or a miscalculation of parenting time. Orange County courts use the Florida Child Support Guidelines, a formula that calculates support based on both parents' income and how much time each parent spends with the child. If the facts that went into that formula have shifted, the order may no longer match what the guidelines say it should be.

Key Takeaways

• You file a motion to modify in Orange County Family Court, not a new case, and you must show the court that circumstances have changed substantially since the original order.
• The Florida Child Support Guidelines calculate support based on both parents' income and parenting time, so changes to either one can justify a new calculation.
• You will need recent pay stubs, tax returns, and documentation of any custody or income changes to present to the judge.
• The process typically takes two to four months from filing to a judge's decision, though it can be faster if both parents agree on the new amount.
• If you cannot afford a lawyer, Orange County has legal aid offices and court self-help centers that provide free guidance on filing paperwork.

The difference between modifying and contesting

In Orange County courts, "modifying" and "contesting" are often used interchangeably, but the legal process is the same: you file a motion to modify child support in the same family court case that created the original order. You do not start a new lawsuit. The motion tells the judge what has changed and asks them to recalculate support under the current circumstances.

A modification motion is the standard route when both parents agree that something has changed — a job loss, a custody shift, or a second child. A contested modification is what happens when one parent files the motion and the other parent disagrees with the request or the proposed new amount. Either way, you are asking the same court to reopen the same case and issue a new order.

What counts as a substantial change in circumstances

Florida law requires a "substantial and material change in circumstances" before a judge will modify an order. This is a real threshold — the court will not lower or raise support just because one parent wants a different number. The change must be significant enough that the original order no longer reflects the reality of both parents' situations.

A job loss counts. If you were earning $60,000 when the order was issued and you are now earning $35,000, that is substantial. A job change that increases your income also counts — if you were making $40,000 and now make $75,000, the other parent can ask the court to increase support. A shift in custody counts too: if the original order assumed you had the child 20% of the time and you now have them 50% of the time, that changes the support calculation. A new child born to either parent can justify a modification because the guidelines account for other children you are supporting. A significant change in either parent's health insurance costs, childcare costs, or other expenses that the guidelines factor in also qualifies.

What does not usually count: a minor income fluctuation, a voluntary job change to a lower-paying position (courts view this skeptically), or straightforward wanting a different arrangement. The change has to be involuntary or circumstantial, not a choice made to avoid support.

How to file a motion to modify in Orange County

You file your motion in the Orange County Family Court, which is located in the Orange County Courthouse at 425 North Orange Avenue in downtown Orlando. You can also file by mail or through the court's e-filing system if you have a case number from the original order.

The document you file is called a Motion to Modify Child Support. It must include your case number, the names of both parents, the child's name, a clear statement of what you want changed, and a detailed explanation of what has changed since the original order. Attach recent pay stubs (usually the last two months), your most recent tax return, and any documentation of the change — a termination letter, a new job offer, custody paperwork, or a birth certificate for a new child.

You must also file a Financial Affidavit, a sworn statement of your current income, expenses, and assets. Orange County provides a blank form on the court's website. This form is what the judge uses to recalculate support under the Florida Child Support Guidelines. If you do not file an accurate Financial Affidavit, the judge may rule against you or order you to pay the other parent's attorney fees.

After you file, you must serve the other parent with a copy of everything you filed — the motion, the affidavit, and all attachments. Serving means delivering the papers to them in person, by certified mail, or through their attorney if they have one. You then file a proof of service with the court showing that you served them. This step is mandatory; if you skip it, the court will not hear your case.

What happens after you file

Once you file and serve the motion, the other parent has 20 days to respond. They can agree with your request, disagree and propose a different amount, or ask for a hearing. If both parents agree on the new amount, you can submit a written agreement to the judge, who will usually approve it without a hearing. This is the fastest path and typically takes three to six weeks from filing to a new order.

If the other parent disagrees, the case moves toward a hearing. Before the hearing, the court may order both parents to attend mediation — a session with a neutral third party who tries to help you reach an agreement. Orange County has a mediation program, and the cost is usually split between the parents or waived if you cannot afford it. Many cases settle in mediation, which again saves time and avoids a trial.

If mediation does not work, you will have a hearing in front of a family court judge. At the hearing, both parents present evidence of their income, expenses, and the change in circumstances. The judge listens to both sides, reviews the Financial Affidavits and supporting documents, and issues a new order. The hearing typically lasts 30 minutes to an hour. You can represent yourself or bring a lawyer. If you represent yourself, the judge will still expect you to follow the rules of evidence and procedure, though judges are often more lenient with self-represented parties.

Getting help with paperwork and court procedures

If you cannot afford a lawyer, Orange County has free resources. The Orange County Legal Aid Society provides free legal help to people who meet income limits. You can reach them at 407-841-8686. They can review your motion, help you fill out the Financial Affidavit, and sometimes represent you in court.

The Orange County Courthouse also has a Family Law Self-Help Center, located in the courthouse itself. Staff there do not give legal information, but they can explain how to fill out forms, what documents you need, and how the court process works. They can also tell you whether your case qualifies for fee waivers if you cannot afford filing fees.

If you hire a private lawyer, expect to pay between $1,500 and $5,000 for a straightforward modification, depending on whether the case settles or goes to trial. Many family law lawyers in Orange County offer free initial consultations, so you can discuss your situation and get a cost estimate before committing.

What the judge considers when recalculating support

The judge does not have discretion to set support at any amount they choose. Florida law requires them to use the Child Support Guidelines, which is a mathematical formula. The formula takes both parents' gross monthly income, subtracts certain deductions (like taxes and health insurance), and applies a percentage based on how many children are involved and how much parenting time each parent has.

If you have the child 50% of the time, the calculation is different than if you have them 20% of the time. If you are supporting another child from a different relationship, that reduces the amount you owe. If you pay for the child's health insurance or childcare, those costs are factored in. The judge must follow the guidelines unless both parents agree to a different amount or the judge finds that following the guidelines would be unjust or inappropriate — a high bar that rarely succeeds.

This means your case largely comes down to proving your actual income and the actual change in circumstances. If you lost your job, bring the termination letter and recent pay stubs showing zero income. If you got a raise, bring your new pay stubs and the job offer. If custody changed, bring the custody order. The clearer your documentation, the stronger your case.

Frequently Asked Questions

Can I ask the court to lower support retroactively — back to when my circumstances changed?

Yes, but only back to the date you filed the motion. If you lost your job in January but did not file until June, the new lower amount starts in June, not January. This is why filing quickly after a change matters. Some judges will order the other parent to reimburse you for overpayments between the change and the filing date if you can show you acted promptly, but this is not may provide.

What if the other parent refuses to disclose their income or lies about it?

Tell the judge. If the other parent does not file a Financial Affidavit or does not show up to the hearing, the judge can order them to do so or can rule against them based on the evidence you present. If you believe they are hiding income, you can ask the judge to order discovery — a formal process where each parent must answer questions and produce documents under oath. This takes longer and costs more, but it is available if you need it.

Do I have to go to court in person, or can I do this by phone or video?

Orange County courts allow video appearances in some family law cases, especially if both parents agree. Ask the court clerk when you file whether your case qualifies. If it does not, you will need to appear in person at the courthouse. The judge will tell you the hearing date and time when the case is scheduled.

What if I agree with the other parent on a new amount but we want to skip the hearing?

You can submit a written agreement called a Stipulation and Consent Order to the judge. Both parents sign it, agreeing to the new support amount. The judge reviews it and, if it appears fair and follows the guidelines, signs it and issues a new order. This is the fastest and cheapest route and usually takes two to four weeks from filing to a final order.

Can the other parent contest my modification motion?

Yes. They can file a response saying they disagree with your proposed amount and offer a different one. If you cannot agree, the case goes to a hearing where the judge decides. The judge is not bound by either parent's proposal — they will calculate the correct amount under the guidelines based on the evidence presented.
