Custody is the part of divorce that keeps parents up at night, and in Kentucky there isn’t one clean test a judge applies to settle it. In Kentucky, custody comes down to a best interest of the child standard, weighed against eleven factors, with a starting assumption of equal parenting time that’s been written into the law since 2018.
That assumption catches parents off guard. You may have pictured a fight for primary custody. Kentucky courts start from the opposite direction, joint custody and roughly equal parenting time, unless someone proves that arrangement is wrong for this child.
At Straw-Boone Doheny Banks Mudd Catalano & McKinney, we’ve watched that starting point shape outcomes for three decades of Louisville families, and we can walk you through what it means for yours.
What “Best Interest of the Child” Means Under Kentucky Law
Every custody decision in Kentucky answers one question: what serves this specific child. Kentucky Revised Statute 403.270 makes that the sole legal standard, splitting custody into two pieces parents often lump together.
Legal custody covers who decides on schooling, medical care, and religion. Physical custody, now usually called parenting time, covers where the child sleeps on a Tuesday night.
The 11 Factors a Judge Weighs
No factor decides a case alone. KRS 403.270 lists eleven factors in total. The ones below come up in nearly every case:
- What each parent, and any de facto custodian, wants for the arrangement
- What the child wants, once old enough to have a reasoned opinion
- How the child relates to each parent, siblings, and anyone who shapes their daily life
- Why each adult is fighting for the outcome they’re asking for
- How settled the child already is in their home, school, and community
- The mental and physical health of everyone involved
- Whether a parent will let the child keep a real relationship with the other parent
A willingness to share time carries more weight than most parents expect.. Judges read reluctance to share time, or quiet efforts to edge the other parent out of school events, as a signal about which household serves the child better. A parent who builds a case around winning rather than co-parenting can undercut their own position here.
The remaining four look more narrowly at:
- Any court finding of domestic violence and how it affected the child
- How much a de facto custodian has actually cared for and supported the child
- Why a parent placed the child with that caregiver in the first place
- The circumstances of that placement, including whether domestic violence or a need to work or attend school played a role
These final factors provide the court with additional context regarding caregiving history and any potential risks to the child’s safety.
Kentucky’s Joint Custody Presumption
A Louisville child custody lawyer can help you evaluate how the statutory factors and equal-parenting presumption apply to your circumstances.
Since 2018, Kentucky law has presumed that joint custody and equal parenting time serve a child’s best interest, and the parent who wants something different carries the burden of proving it. That flips how parents expect this process to work. You aren’t building a case to earn time with your own child. You’re responding to a starting point that already favors roughly equal time.
When the Presumption Falls Away
The equal-time presumption disappears the moment a domestic violence order enters against a parent, no exceptions. KRS 403.315 strips it as to that parent, whether the case sits in Jefferson County or anywhere else in Kentucky, and the court falls back on the full eleven-factor analysis.
Kentucky’s Cabinet for Health and Family Services and the Kentucky Court of Justice both maintain resources for parents navigating custody alongside a protective order, and a child custody attorney can help you understand what evidence moves that needle.
Changing an Order Later
A custody order isn’t permanent, though the path to changing it depends on timing. Modification requests generally need:
- A real change in circumstances since the last order, not just frustration with the schedule
- Proof the new arrangement serves the child better, not just one parent
- Documentation such as school records or evidence of a co-parent’s noncompliance
Inside the first two years, you generally need to show either that the child’s current home puts their safety or wellbeing at serious risk, or that the other parent has since placed the child with a new caregiver who meets Kentucky’s de facto custodian test.
Frequently Asked Questions About Child Custody Determined
Can a child decide which parent to live with in Kentucky?
No, there’s no set age where a kid picks their house. Judges will listen to an older child’s wishes, but it’s one of eleven factors, not the deciding vote.
What’s a de facto custodian?
Someone who has been both the child’s main caregiver and main financial supporter for at least six months (if the child is under three) or one year (if the child is three or older), generally within the last two years. A judge must find this true by clear and convincing evidence before the person legally counts as a de facto custodian. This is usually a grandparent or other relative.
Does custody affect child support?
Yes, parenting time feeds directly into Kentucky’s child support formula, which weighs both parents’ gross income through worksheets from the Cabinet for Health and Family Services. Even in a true 50/50 split, the higher earner typically still owes something.
A Louisville child support lawyer can explain how parenting time and both parents’ income affect the guideline calculation.
Can I move out of state with my child after a custody order?
Not without notice. Kentucky requires 60 days written notice before relocating a child more than 100 miles or out of state, and the other parent can object and force a hearing.
