The 2018 joint-custody presumption
A 2018 law amended KRS 403.270 to create a rebuttable presumption that joint custody and equally shared parenting time serves the child's best interest. The first permanent-custody law of its kind in the country.
Both parents begin near equal footing. A parent seeking a different plan is asking to overcome a presumption.
Rebutting the presumption
The presumption can be overcome by a preponderance of the evidence. Where a deviation is warranted, the court builds a schedule that maximises each parent's time consistent with the child's welfare.
So moving off equal time takes exact, dated facts โ safety, distance, a parent's availability. Not general criticism.
Legal and physical custody
Kentucky's joint-custody framework covers both decision-making and time. "Full custody" often means sole custody plus most parenting time. This runs against the presumption.
Name what you actually need and why the child's interest supports it.
What the numbers don't decide
The household shares above show where Kentucky children live, not how custody was ordered. Many arrangements are agreed rather than litigated.
Use the figures as context only. The presumption and your evidence decide the case.
Evidence to move off, or defend, equal time
Log parenting time, exchanges and missed time with dates, and keep the messages behind each change. If you allege a safety concern, record the event, source, response and effect on the child.
Casewell keeps those entries and files together. So a Kentucky lawyer can build the case on a clean record.
The presumption, in the statute's own words
Kentucky is unusually direct here.
There shall be a presumption, rebuttable by a preponderance of evidence, that joint custody and equally shared parenting time is in the best interest of the child (KRS 403.270).
That covers both halves of a case at once. Joint custody is the decision-making, and equally shared parenting time is the schedule.
A presumption is a starting point rather than a promise. It puts the work of arguing on whichever parent wants something different.
Why older advice gets Kentucky wrong
Kentucky was the first state to put an equal-parenting-time presumption into law, in 2018. Most general US custody advice was written for states that never had one.
So an article about improving your odds of primary custody may be describing a fight that Kentucky does not start from. Here the default is already equal, and the question is whether anything justifies moving off it.
Check the date and the state on anything you read. A parent preparing for the wrong starting line usually gathers the wrong evidence.
Before you file in Kentucky
Save any current order, track parenting time for a few weeks, and draft your proposed schedule in plain, step-by-step detail.
A Kentucky family-law lawyer can weigh it against KRS 403.270 and your county's practice before filing.

Is Kentucky a 50/50 custody state?
Closer than most. KRS 403.270 presumes that joint custody and equally shared parenting time serve the child. That presumption can be rebutted by a preponderance of the evidence.
Does general US custody advice apply in Kentucky?
Often not. Kentucky has started from a presumption of equally shared parenting time since 2018. So advice written for states without one can point you at the wrong starting position.
Does Kentucky publish a full-custody success rate?
No. Public data does not give a complete percentage of Kentucky cases in which mothers or fathers receive sole legal and physical custody. Household statistics describe where children live, not court outcomes.
Do these statistics show that mothers get custody more often in Kentucky?
They show the sex of the household householder in a living-arrangement table. They do not show legal custody, parenting-time percentages, the reason for the arrangement, or whether a court was involved.
Can documentation improve my chances of custody?
Yes. Good records can definitely improve your chances. They help you arrive prepared with clear, dated evidence in the right format. They give your lawyer a head start, saving time and fees. They cannot guarantee an outcome, but they can strengthen your case.
What should I record first?
Start with the current arrangement, then record each material change with the date, what was expected, what you observed, the source, the child-related effect, your response, and the outcome. Use Casewell to keep the entry and supporting file together.
