One of the most common misconceptions in Florida family law is that 50/50 shared custody means no child support. It is a common misconception among parents that expenses at both homes will cancel out if the child spends the same amount of time at both.
But this is not the case in Florida.
Even if you have a 50/50 time-sharing arrangement with your co-parent, you could still be required to pay child support. Child support is not a right of the parent, but of the child under Florida law. The state’s purpose is to ensure that your child has the same quality of standard of living in both homes.
For those going through a divorce or a paternity case, it’s important to understand how the 50/50 custody and child support Florida rules actually apply.
How Does Florida Calculate Child Support with 50/50 Custody?
The state of Florida uses a process called the Income Shares Model to determine child support. This model assumes a child should be given a share of parental income corresponding to what they would receive in a single-family home.
The state uses a formula called the child support calculator to determine the outcome. These are the key factors used in the calculation:
- Individual net incomes:
Each parent’s gross income (salaries, bonuses, business profits, etc.) is calculated and deducted by any allowable expenses, such as taxes and health insurance premiums, to determine the parent’s net monthly income.
- The number of children:
The total baseline (standard) amount of support is calculated based on the number of children the parents share.
- The number of overnights:
How many overnights each parent gets with the child is a huge factor in the final calculation.
Substantial Time-Sharing Rule and the Gross-Up Method
If the parent receives the child for at least 20% of the overnights in the year (73 or more overnights), the special formula, known as the Gross-Up Method, is activated.
Both parents easily cross this 73-overnight threshold, since 50/50 custody means each parent has the child for approximately 182.5 nights per year.
If this occurs, the court is likely to assume that the child’s expenses are paid twice over for two separate and complete households, such as two sets of toys, two sets of utilities, and additional food costs. To compensate for this, the base child support is increased by 50% (a factor of 1.5). This total is then split between the parents according to their respective percentages of the combined income and the number of overnights they have.
Why One Parent Still Pays in an Equal Split
Why then does one parent have to make a check if it is a perfectly 50/50 split of time? It’s all about money.
- Significant income disparities
This is one of the most frequent situations in joint custody. In such cases, one parent may have a significantly higher income than the other parent. As a result, there is an enormous difference in their financial possibilities. Under such circumstances, intervention by the courts becomes inevitable.
In most cases, the parent with higher income should make child support payments. The obligation exists regardless of whether the child spends the same amount of time with each parent. The payments go to the parent with the lower income.
The primary aim is the protection of the child. A child should not have a great life at one house and a struggling life at the other. The law wants to keep things stable. The child deserves a comfortable environment in both places.
Without this support, the child might have a big bedroom and great food at a wealthy home. Then, they might go to a crowded apartment with very little at the other. This sudden shift is hard on a young child.
Child support balances this scale. It makes sure both homes are safe, warm, and comfortable. The child gets to enjoy the financial success of both parents. This is why the court focuses heavily on income differences. They look at the money, not just the days on a calendar.
- Expenses related to children
When calculating child support, it doesn’t only consider simple living expenses such as rent and food. They also look at who the direct payers are for significant recurring expenses. The calculator takes into account:
- The health insurance premiums were paid for the child.
- Your insurance does not cover medical and vision expenses.
- Child care for working parents.
If Parent A has a high income and the child is fully covering health insurance and daycare costs, those amounts will be credited to Parent A in the child support calculator. This credit may significantly reduce the amount of support Parent B must provide to Parent A, or, in some instances, reverse the payments.
Can Parents Agree to No Child Support in Florida with 50/50 Custody?
In cases where the co-parents are on friendly terms, one may wonder if parents can agree to a no-child-support arrangement.
The answer is yes, but it is extremely hard to obtain a judge’s approval.
In Florida, parents don’t really own child support; they own their child. This means that you cannot just agree to give up child support in any arrangement you make. Any agreement to waive or decrease support shall be heard and formally approved by the judge.
The Florida Child Support Waiver and 50/50 Custody
If you wish to get a judge to grant a Florida child support waiver 50/50 custody agreement, you must be able to offer a very good case.
The court will be looking for certain conditions where a $0 support order is warranted:
- Nearly equal incomes:
Both parents should have very close incomes.
- Equally shared direct costs:
Parents need a clear and reliable way to divide all other expenses. These expenses can be uniforms, school fees, and sports expenses.
- The child’s best interests:
You have to show the judge that it will not cause any financial harm or deprivation to the child in either home if you waive formal support.
A judge will most likely refuse to grant a waiver if there is a significant salary disparity or if one parent is having a financial challenge. They will request regular guideline support to ensure that the child is safeguarded.
When Can You Change a Kid Support Order?
Your child’s life is not static, and neither is your financial life. If your circumstances change after your initial 50/50 custody support order is set, you can ask the court to modify it.
To make a significant and permanent modification to child support in Florida, it is necessary to establish a significant, permanent, and unintentional change in circumstances.
Some of the most frequently cited grounds the court will look at are:
- Change in income:
Either parent is rendered unemployed, receives a significant salary increase, or is injured and cannot return to work.
- Change in the real-time-sharing schedule:
One of the parents loses their job, gets a pay rise, or becomes disabled and cannot go to work.
- Change in the actual schedule of time-sharing:
If both parents sign an agreement regarding a time-sharing schedule, but the child actually spends 80% of nights with one of them, the child support payment should be increased proportionally.
Remember, never make an informal agreement with your co-parent to modify or terminate child support. If you both agree in writing on a piece of paper, it is not legally binding. A specific petition must be filed with the court to make changes to the order. You may be liable for unpaid back support (arrears) even after you stopped paying, under a handshake agreement.
Conclusion
50/50 time-sharing in Florida is a great way to be involved in your child’s life. It does not, however, automatically remove your financial liability to the law. Florida child support is extremely precise. Child support is likely to be awarded if there is a difference in income between you and the other parent. This is the same if one of you has to pay the majority of the health care and daycare expenses.
It is a big risk, and you cannot go at it by yourself. You need someone who can represent you in court and who appreciates the significance of your family’s future.
