The 50/50 Timesharing Presumption Two Years In: What Florida Courts Are Actually Doing
When Florida amended Fla. Stat. § 61.13 to add a rebuttable presumption of equal timesharing, effective July 1, 2023, the public conversation focused on the word "rebuttable." The legislature was careful. The presumption was framed as a starting point, not a mandate. Either parent could overcome it with evidence under the 20 best-interest factors.
That framing was technically correct. It was also misleading.
In practice, the presumption has done exactly what its supporters said it would do, and exactly what its critics warned it would do. It has shifted the entire procedural posture of contested custody cases in the Fourth Judicial Circuit. The default starting point in 2026 is 50/50. Parents who want a different schedule now bear the burden of moving the court off that default — and the evidence that actually works to do that is narrower than most people think.
After three years of the new framework, here is what is actually happening in Duval, Clay, and Nassau County family courts.
Three Categories Where 50/50 Sticks Every Time
When the facts are clean, the court goes 50/50, and quickly. Three categories of cases now resolve this way as a matter of routine:
Both parents engaged, geographically close, no concerns. When mom and dad both attend pediatrician appointments, both show up at school events, both maintain a home suitable for the children, and live within a reasonable commute of each other and the schools — equal timesharing is essentially automatic. There is no longer any judicial reluctance to do it. Three years ago, this same fact pattern produced a 60/40 or 65/35 split. Today it produces a week-on/week-off rotation.
Reasonably amicable separations with no fault on either side. The "good divorce" — where the parties acknowledge the marriage is over but don't have weaponized history against each other — defaults to 50/50 across the board. Mediators in the Fourth Circuit are now drafting these schedules into MSAs without any back-and-forth.
Older children with established routines that work for both households. Once children are 8 or older with after-school activities, sports, and friendships, the court's analysis under § 61.13(3) becomes about preserving routine. If both parents can deliver the routine, the schedule is 50/50.
These categories cover the majority of contested custody cases. The presumption is doing what the legislature intended in those cases. Faster outcomes, less litigation, less expense.
Three Categories Where the Presumption Gets Rebutted
The presumption is not absolute. There are three categories of cases where Fourth Circuit courts have consistently declined to order 50/50 since the statute took effect:
Documented domestic violence — even without a criminal conviction. Florida Statute § 61.13(2)(c)(2) creates a separate rebuttable presumption against shared parental responsibility when a parent has been convicted of certain misdemeanor domestic violence offenses, or any felony domestic violence. But Florida courts are also using the 20 best-interest factors of § 61.13(3) to deviate from 50/50 when there is documented domestic violence even without a conviction — police reports, injunction findings, medical records, witness statements. The threshold is lower than people realize.
Substance abuse with a recent pattern. Recent DUI, recent positive drug test in a custody-related context, recent treatment admission — these are producing supervised or limited timesharing schedules, not 50/50. The court is not going to put children in a 50% rotation with a parent whose substance use has been recently documented. Older or fully resolved issues are treated differently.
Documented historical caregiving where one parent was the everyday parent. This is the category that has surprised the most people. The stay-at-home parent who handled doctor appointments, school pickups, homework, bedtime — and can document it — is still able to rebut the presumption when the other parent simply was not the primary caregiver during the marriage. The key word is document. Self-serving testimony does not work. Bank statements showing one parent paid all the daycare. Medical records showing one parent always brought the child. Email and text chains showing one parent was the school's point of contact. These move the needle.
Evidence That Is Working
When parents try to rebut the 50/50 presumption, the evidence that has been producing results in 2026 cases falls into a narrow set:
Pediatric and dental records showing a single parent always brought the child. These are extracted from the provider directly with a release. The pattern is unambiguous and admissible.
School records identifying the primary contact parent. Most schools document who calls in absences, who comes to conferences, who picks up early. This is exactly the kind of evidence courts want to see.
Therapist records and recommendations. Children in family therapy during the separation period — when the therapist makes a specific recommendation about timesharing structure — that recommendation gets weight. It is one of the few categories of expert opinion the court routinely credits.
Communication records showing decision-making patterns. Texts, emails, and shared-calendar entries that establish who is making the day-to-day decisions about the children.
Geographic distance and commute analysis. When parents live far enough apart that 50/50 means the children spend large parts of the school week in transit, the practical impossibility argument lands.
Evidence That Isn't Working
Equally instructive is what does not work to rebut the presumption:
Self-serving testimony without documentation. "I always made dinner." "He never helped with homework." Without records, this is treated as he-said/she-said and the court defaults to the presumption.
Vague claims about "the primary bond." Family courts in 2026 are not making attachment-theory rulings based on testimony. They want behavior-based evidence.
Old or single incidents. A DUI from eight years ago that was followed by sustained sobriety does not rebut anything. A single missed pickup does not rebut anything. The court is looking for patterns in recent time periods.
Conduct of the other parent that doesn't bear on parenting. Affairs, financial misconduct, even general unpleasantness — none of it moves the timesharing analysis unless it specifically affected the children.
What This Means for Parents About to File
If you are about to file for divorce in Duval, Clay, or Nassau County and you have minor children, the practical advice has changed:
Document caregiving now, not after the case starts. If you are the everyday parent and you want to argue for primary timesharing, the evidence has to predate the litigation. Save records, save communications, save calendars. Most parents do not realize how much routine caregiving leaves a paper trail until they go looking for it.
Do not assume your spouse will agree to a different schedule. Three years ago, agreeing to a non-50/50 schedule in mediation was common. Today, the spouse on the receiving end of a 50/50 result has very little incentive to negotiate down. Mediation strategy has shifted accordingly.
Build the documentation case for the deviation factors before you file. If domestic violence, substance abuse, or geographic constraints are the basis for asking the court to deviate — the supporting evidence needs to be ready at the temporary-relief hearing, not at trial. Temporary orders set a pattern that becomes very difficult to change at final judgment.
Talk to an attorney early. This is not the kind of case where you wait until the other side files and then react. The presumption has compressed the timeline for evidence-building dramatically.
A Note on the Long View
The presumption is not going to be repealed. It enjoys broad support across the Florida bar and the legislature, and the early data on contested-case outcomes has been favorable from a court-administration perspective — fewer trials, faster resolutions, lower per-case cost.
What is going to keep evolving is the case law on what kinds of evidence are sufficient to rebut. The Fourth Circuit, the Fifth DCA, and the First DCA are now producing appellate decisions that refine the contours. Each decision narrows or clarifies the standard. An attorney who handles these cases regularly is tracking that body of law in real time. An attorney who does not is working from the version of the statute that existed in 2023.
If you are facing a custody decision in 2026, the question is not whether the presumption applies. It does. The question is whether your facts fit one of the categories where it sticks, or one of the categories where it can be rebutted — and whether you have the evidence to prove which one you're in.
That analysis is what a consultation is for.
