A final judgment is not always final. Florida courts can modify parenting plans, timesharing schedules, child support and many alimony awards when circumstances change enough. The rules are strict, and a weak petition costs time, money and credibility. Reyes Miller Law Group handles modification cases for parents and former spouses in Palm Beach, Miami-Dade, Broward, Monroe, Orange, Hillsborough and Leon counties.
How Reyes Miller Law Group handles modification cases
Timesharing and parenting plan changes
A new work schedule, a move, a child's changing needs, a parent who stopped showing up: we present the evidence that the current plan no longer serves the child.
Child support changes
A job loss, a raise, a new child care cost, a change in overnights: we run the numbers to see whether the change meets the legal threshold before anything is filed.
Alimony changes
We pursue or defend petitions to reduce, increase or end alimony based on a substantial change in circumstances, retirement or the recipient's supportive relationship.
Defending a modification
If your former spouse or co-parent has filed to change the order, we test whether their change is real, substantial and enough under the law.
Agreed modifications
When both sides agree, we put the change in writing and get it approved so it is enforceable, rather than a handshake neither parent can rely on.
What Florida law says
Parenting plans and timesharing
Under section 61.13(3), Florida Statutes, a parenting plan or timesharing schedule may be modified only on a showing of a substantial and material change in circumstances, and only if the modification is in the child's best interests. Since 2023, the change no longer has to have been unanticipated.
Child support
Support may be modified when there is a substantial change in circumstances. For the guidelines alone to show a substantial change, the new guideline amount must differ from the current order by at least 15 percent or $50, whichever is greater (section 61.30(1)(b)).
Alimony
Alimony can be modified or ended under section 61.14 when there is a substantial change in circumstances, unless the parties agreed it could not be. A supportive relationship with another person can also justify a reduction or termination.
Changes date from the filing
A support modification generally can be made retroactive only to the date the petition was filed, which is why waiting can cost money.
Informal changes are risky
Changes the parents agree to informally are not enforceable. If one parent later goes back to the original order, the court enforces the order as written.

Frequently asked questions
What counts as a substantial change in circumstances?
It depends on the facts. Examples courts often consider include a significant change in a parent's income, work schedule or health, a move, a parent regularly not using their timesharing, or a change in the child's needs. It has to have happened since the last order.
Can I lower my child support if I lost my job?
Possibly. An involuntary loss of income can support a modification, but the court may impute income if it finds the loss was voluntary. File promptly: a reduction generally cannot go back earlier than the date you filed.
Can my child ask to change the schedule?
A child's reasonable preference can be one factor, but it does not decide the case at any age.
How long does a modification take?
An agreed modification can be approved relatively quickly. A contested one moves much like a new case, with financial disclosure, mediation and, if needed, a hearing.
Can alimony still be modified after the 2023 law?
Yes. Section 61.14 still allows modification on a substantial change in circumstances, and it now addresses the paying spouse's reasonable retirement as a basis for a change.
