Is Kentucky a 50/50 Custody State? Exceptions and Child Support

Yes. Kentucky is a 50/50 custody state by default. Since 2018, KRS 403.270 has required family courts to start every case with a rebuttable presumption that joint custody and equally shared parenting time serve the child’s best interest.¹ That presumption is a starting point, not a guaranteed outcome. Either parent can present evidence that a different schedule would work better for the child, and the judge can adjust from there. What sets Kentucky apart is the clarity of that baseline: the parent who wants something other than equal time is the one who has to explain why.

How the Equal Time Presumption Works

When a Kentucky court opens a custody case, it treats a 50/50 schedule as the default. To move off that default, a parent must rebut the presumption by a preponderance of the evidence, which means showing it is more likely than not that a different schedule would serve the child better.¹

Even when a judge does depart from equal time, the statute doesn’t hand the court a blank check. The law still requires the judge to build a schedule that maximizes each parent’s time with the child, as long as that is consistent with the child’s welfare.¹ So a court that lands on a 60/40 or 70/30 split should explain on the record why equal time wouldn’t work and why the chosen division still gives the child as much contact with both parents as the situation allows.

When the 50/50 Presumption Does Not Apply

The equal-time presumption disappears when a domestic violence protective order has been entered against one of the parents. Under KRS 403.315, if a court has issued or is in the process of issuing a protective order against a party in the custody case, the judge is not required to start from a 50/50 baseline for that parent.² The court skips straight to evaluating the best interest factors and decides custody from the evidence in front of it.

The distinction matters. The protective order itself removes the presumption. The other parent doesn’t have to independently prove the presumption should be rebutted; the order does that work. The statute also protects a parent who left the family home because of physical harm or serious threats from being penalized for that decision.¹

What the Court Weighs If a Parent Rebuts the Presumption

Whether the presumption applies or has been set aside, the court’s ultimate job is to decide what arrangement fits the child’s best interest. Kentucky law lists specific factors the judge must weigh, and no single factor automatically controls the result. The court looks at:

What custody arrangement each parent, and any de facto custodian, is asking for.
The child’s own wishes, though the court considers whether a parent may have influenced them.¹
The child’s relationships with each parent, siblings, and anyone else who plays a significant role in the child’s life.
How well the child is adjusted to their current home, school, and community.
The mental and physical health of the child and both parents.
Any finding that a parent committed domestic violence against the other parent or a child.
Why each adult is pursuing the arrangement they’ve requested, and how likely each parent is to encourage the child’s relationship with the other parent.¹

That last factor comes up constantly in contested cases. Judges pay close attention to which parent is more willing to support a healthy co-parenting relationship. A parent who badmouths the other, blocks phone calls, or plays scheduling games hands the other side a strong argument. The one exception is that the court won’t hold it against a parent for limiting contact if the other parent committed domestic violence against them or the child.

De Facto Custodians

Kentucky gives standing to a “de facto custodian,” someone other than a parent who has been the child’s primary caregiver and financial supporter. To qualify, the person must have lived with and supported the child for at least six months if the child is under three, or at least one year if the child is three or older, and a court must find by clear and convincing evidence that the person meets the definition.¹ Once recognized, a de facto custodian has the same standing as a parent, and the 50/50 presumption applies to them as well.

Does 50/50 Custody Mean No Child Support?

Equal parenting time does not zero out child support in Kentucky. The state uses an income-shares model, and when parents share time equally, the parent with the higher gross monthly income is treated as the paying parent.³ The reasoning is straightforward: a significant income gap between two households would give the child a very different standard of living depending on which home they were in, and support payments close that gap.

Kentucky does offer a shared parenting time credit that reduces the paying parent’s obligation based on how many overnights they have. To qualify for any credit, a parent must have the child at least 88 days per year. The credit rises on a sliding scale up to 50% for parents with exactly equal time (182 days).³ The scale runs as follows:

88 to 115 days: 15% credit
116 to 129 days: 20.5% credit
130 to 142 days: 25% credit
143 to 152 days: 30.5% credit
153 to 162 days: 36% credit
163 to 172 days: 42% credit
173 to 181 days: 48.5% credit
182 or more days: 50% credit

The credit applies against the paying parent’s share of the total support obligation, not against the total itself. If the guidelines set total support at $1,200 per month and the higher-earning parent’s share is $800, a 50% shared parenting credit reduces that parent’s payment to $400. The credit is not automatic. You have to file a motion asking for it.

Which Parent Claims the Child on Taxes

An equal custody schedule raises a predictable question each tax season: who claims the child? Federal law has a tiebreaker. When a child spends an equal number of nights with each parent, the parent with the higher adjusted gross income is treated as the custodial parent for tax purposes.⁴ That parent gets the default right to claim the child as a dependent, the child tax credit, and head of household status if they otherwise qualify.

The custodial parent can voluntarily release the right to claim the child by signing IRS Form 8332, which lets the other parent claim the child tax credit and additional child tax credit for a specific year or for all future years.⁵ Some parents alternate years. Form 8332 transfers only the child-related credits; it does not transfer head of household filing status, which stays with the parent who actually maintained the home where the child lived for more than half the year.⁶ If both parents claim the same child, the IRS applies the tiebreaker rules, which usually means the lower-earning parent loses the credit and may owe back taxes plus interest. Spell this out in the parenting plan rather than sorting it out at filing time.

Can a Kentucky Court Even Hear Your Case?

Before any Kentucky court applies the 50/50 presumption, it must have jurisdiction. Kentucky adopted the Uniform Child Custody Jurisdiction and Enforcement Act. Under KRS 403.822, a Kentucky court can make an initial custody determination only if Kentucky is the child’s “home state,” meaning the child has lived in Kentucky with a parent for at least six consecutive months before the case is filed.⁷ For a child younger than six months, the home state is wherever the child has lived since birth.

This matters when parents live in different states or one has recently moved. A parent who relocates to Kentucky and immediately files for custody will likely find the court lacks jurisdiction if the child hasn’t lived in Kentucky for six months yet. Physical presence alone doesn’t give a Kentucky court authority to decide custody.⁷ If Kentucky isn’t the home state, the 50/50 presumption never enters the picture, because a different state’s law will govern.
