What 50/50 Custody Means in Florida: Presumption, Schedules, Support

In Florida, 50/50 custody means each parent has roughly equal overnights with the child under a court-approved time-sharing schedule, and since July 1, 2023, that equal split is the legal starting point. State law doesn’t actually use the phrase “50/50 custody.” It splits the idea into shared parental responsibility, which is how parents make major decisions together, and time-sharing, which is the schedule of overnights.¹ Both go into a written parenting plan, and neither automatically follows from the other.

Sole parental responsibility, where one parent makes all major decisions alone, is the exception. A court orders it only after finding that shared responsibility would be detrimental to the child.²

The Presumption of Equal Time-Sharing

HB 1301 added a rebuttable presumption to Florida Statute § 61.13 that equal time-sharing is in a minor child’s best interests.³ In practice, the court begins every case assuming a roughly even split is appropriate. A parent who wants something different — 60/40, 70/30, or majority time — carries the burden of proving, by a preponderance of the evidence, that equal time-sharing would not serve the child’s best interests.²

Before this change, judges had broad discretion to set whatever schedule they believed was best, with no default in either direction. The presumption doesn’t take that discretion away entirely. The court still runs through the full best-interest analysis and must put specific written findings in any order that creates or modifies a schedule.² What the presumption changes is the starting point and who has to persuade the judge.

What Can Defeat the Presumption

Florida Statute § 61.13(3) lists the factors the court weighs when creating or modifying any time-sharing schedule. Among them:⁴

Each parent’s willingness to encourage the child’s relationship with the other parent and honor the schedule.
Whether a parent prioritizes the child’s needs over their own.
The length of time the child has lived in a stable environment and the value of continuing it.
Whether the plan works logistically, with special attention to school-age children and travel between homes.
The mental and physical health of both parents.
The child’s own preference, if the court finds the child mature enough to express a meaningful opinion.
Each parent’s familiarity with the child’s friends, teachers, medical providers, and daily routines.
Each parent’s ability to maintain discipline, homework, meals, and bedtimes.
Any evidence of domestic violence, sexual violence, child abuse, abandonment, or neglect. When the court considers this evidence, it must acknowledge doing so in writing.
Whether either parent has knowingly given the court false information about these factors.

No single factor controls. A parent who scores poorly on one — say, distance from the other parent’s home — can still get equal time-sharing if the overall picture supports it. Domestic violence carries outsized weight. A conviction for a first-degree misdemeanor or higher for domestic violence creates its own rebuttable presumption that shared parental responsibility would be detrimental to the child.²

Common 50/50 Schedules

Equal time-sharing doesn’t mean one rigid pattern. The right rotation depends on the child’s age, school schedule, and how close the parents live to each other.

Alternating weeks. One full week with each parent. Simple to track. Younger children sometimes struggle with seven consecutive days away from either home.
2-2-3 rotation. Two days with one parent, two with the other, three with the first, and the pattern flips the following week. Shorter gaps between visits, more transitions.
3-4-4-3 rotation. Three days with one parent, four with the other, then they switch. Over two weeks each parent gets seven overnights.
Split weeks. Monday through Wednesday with one parent, Thursday through Sunday with the other, with the longer block alternating.

On top of the regular rotation, a parenting plan spells out separate arrangements for holidays, school breaks, summer vacation, and birthdays. Those override the regular schedule when they apply. Vague plans create enforcement problems later; the more specific the schedule, the fewer disputes over whose weekend it is.

Child Support Still Applies

Equal time does not mean nobody pays child support. This is the single most common misconception. Florida’s child support guidelines are driven by each parent’s income, healthcare costs, and daycare expenses, not by overnights alone.

The statute uses a special formula whenever a parent has at least 20 percent of overnights in a year, roughly 73 nights, which it calls a “substantial amount of time.” A 50/50 arrangement easily clears that threshold, so the substantial-time formula is what applies. The formula compares each parent’s income-based obligation against their share of overnights and produces a net transfer from one parent to the other. When incomes are close, that transfer may be small. When one parent earns significantly more, support is real money even with a perfectly even split. The court can also deviate from the guideline amount based on factors like a parent’s low income, whether each parent actually exercises their scheduled overnights, and the basic necessities of the child’s home.⁵

Modifying a 50/50 Order Later

Life changes. A parent takes a new job, a child starts high school, or one parent moves. Florida allows modifications when two conditions are met: a substantial and material change in circumstances has occurred, and the modification is in the child’s best interests.²

Before 2023, the parent asking for the change also had to prove the new circumstances were unanticipated. HB 1301 removed that extra requirement, making modification somewhat easier to pursue.³ The statute also carves out one specific trigger: if the parents lived more than 50 miles apart when the last order was entered and one later moves within 50 miles of the other, that relocation alone can qualify as a substantial change.² Even with the lower bar, modification isn’t a shortcut to relitigate the original case. The court still runs the full best-interest analysis before changing anything.

When the Other Parent Won’t Follow the Schedule

A time-sharing order isn’t a suggestion. When a parent refuses to honor it without proper cause, the other parent can return to court, and Florida Statute § 61.13(4) lays out what the judge can do:⁴

Award enough makeup time-sharing to compensate for every missed overnight or visit, scheduled at the offending parent’s expense and at the other parent’s convenience.
Order the violating parent to pay the other parent’s attorney’s fees and court costs.
Require the noncompliant parent to complete an approved co-parenting course.
Impose community service, provided it doesn’t interfere with the child’s welfare.
Modify the parenting plan if the non-violating parent requests it and the change serves the child’s best interests.
Hold the violating parent in contempt of court, which can carry fines or jail time.

One protection matters here for both sides: a parent owed child support cannot withhold time-sharing to retaliate, and a parent denied time-sharing cannot stop paying support. The statute keeps the two obligations separate.⁴

Misconceptions Worth Correcting

50/50 doesn’t mean exactly 182.5 days each. It means an approximately equal division of overnights over the year. Holiday and vacation overrides mean one parent may end up with a few more overnights in a given calendar year.
Shared parental responsibility doesn’t mean agreement on everything. Parents collaborate on major decisions like schooling and medical care. Day-to-day choices belong to whichever parent has the child at the time.¹
The presumption isn’t a guarantee. It’s a starting point. Credible evidence that equal time-sharing wouldn’t serve the child’s best interests can move the court off it.²
Equal time doesn’t zero out child support. Support tracks income and expenses, not just overnights.⁵
