How is child support calculated in Florida?
Initially, child support orders are determined mainly by formula, which takes into consideration:
- the incomes of both parties,
- the number of children,
- parental timesharing, and
- the cost of daycare and medical expenses
The Florida child support calculator is intended to give parents a general idea of what to expect when child support is calculated. Child support calculations are typically driven by the numbers- they are primarily based on each parent’s income, childcare costs, medical insurance costs, and the amount of overnight timesharing. However, every situation is different, and there are special circumstances that can affect child support calculations.
Special circumstances may include high medical expenses for a child, special needs, or expenses for the child, or unique timesharing schedules.
The Court will determine the amount of child support owed using the formula that is listed in Florida Statutes 61.30. If there are special circumstances, the Judge may take those circumstances into consideration and deviate by 5% above or below the calculated amount.
The child support obligation is typically paid to the parent who has the majority of overnight timesharing with the child, but if the parent with the majority of timesharing has a significantly higher income, that parent may have the support obligation. Having an attorney to help in your child support case will ensure that the Court understands any circumstances and that the relevant documentation, such as child support guideline worksheets and financial affidavits, are properly prepared and submitted.
Child Support Laws for Unmarried Parents
In Florida, child support laws apply to all parents, whether they are married or not. For unmarried parents, the process for establishing child support is slightly different compared to divorcing parents. The primary difference lies in the establishment of legal paternity. If legal paternity is proven before filing for a child support order, unmarried parents will follow the same procedure as divorcing parents.
However, if legal paternity has not been established, it must be done so before the court will recognize the biological father and include him in the child support filing process. This is because Florida automatically grants the unwed biological mother sole physical and legal custody of the child. To establish paternity, an unwed biological father must undergo a legitimate DNA test, which can be part of a court order or taken voluntarily.
- In Florida, unwed biological mothers automatically receive full parental rights to their child upon birth.
- Florida state law allows both unmarried parents the opportunity to share physical and legal custody of their child evenly.
- Like divorcing parents, unmarried parents who have legally established paternity may receive the legal title of parent.
Establishing paternity is crucial for an unwed father to secure parental rights, including custody and visitation rights.
When Does Child Support End in Florida?
Child support in Florida does not automatically end when the child turns eighteen. Instead, the termination of child support is contingent upon the child’s education status as a high school graduate or on the date of their nineteenth birthday.
- If the child is eighteen and has graduated from high school before this date, child support ends on their eighteenth birthday.
- If the child turns eighteen before graduating from high school, child support ends following their high school graduation.
- If the child is on track to graduate high school after their nineteenth birthday, child support ends following graduation.
- However, if the child is not on track to graduate high school shortly after their nineteenth birthday, termination occurs on their nineteenth birthday
