Kentucky Child Custody Laws: How Custody Is Decided

In Kentucky, child custody is decided based on the "best interests of the child," and the law starts from a rebuttable presumption that joint custody and equally shared parenting time serve that best interest. A parent, a de facto custodian, or the facts of the case can overcome that presumption, but it is the starting point in every Kentucky custody case, whether the parents are divorcing, were never married, or are modifying an existing order.

The Best-Interests Standard and the Joint-Custody Presumption

Under KRS 403.270(2), a Kentucky court determines custody "in accordance with the best interests of the child" and must give equal consideration to each parent. The statute establishes a rebuttable presumption, provable by a preponderance of the evidence, that joint custody and equally shared parenting time is in the child's best interest. This presumption was added to Kentucky law by 2018 Ky. Acts ch. 198, and the current version of KRS 403.270 became effective June 29, 2021.

To decide whether the presumption is overcome, or to work out custody when the presumption does not apply, the court weighs the best-interest factors listed in KRS 403.270(2)(a)-(k), including:

• The wishes of the child's parents, and of the child, as to custody
• The child's relationships with parents, siblings, and any other person who may significantly affect the child's best interest
• The motivation of the adults involved
• The child's adjustment to their home, school, and community
• The mental and physical health of everyone involved
• Whether there has been a domestic violence finding under KRS 403.720
• Each parent's likelihood of allowing frequent, meaningful, and continuing contact between the child and the other parent

Because these factors are fact-specific and weighed together rather than scored individually, the exact outcome in any one family's case depends heavily on the evidence presented, and you should confirm how a Kentucky court is applying them in your particular circumstances.

Time-sensitive note

The presumption and factors described above reflect the version of KRS 403.270 in effect as of the Kentucky statutes database update referenced here (06/29/2026, covering enactments through the 2025 Regular Session). Kentucky's General Assembly can amend custody law in future sessions, so verify you are looking at the current version of the statute before relying on specific details.

When a Non-Parent Seeks Custody: De Facto Custodians

Kentucky law also allows someone who is not the child's legal parent, such as a grandparent or other relative, to be treated the same as a parent for custody purposes if they qualify as a "de facto custodian" under KRS 403.270(1)(a)-(b). This requires clear and convincing evidence that the person has been the child's primary caregiver and primary financial supporter for an aggregate period of at least 6 months if the child is under 3 years old, or at least 1 year if the child is 3 or older. Once a court makes that finding, the de facto custodian has the same standing in the custody case as a parent.

When Domestic Violence Is Involved

The joint-custody and equally-shared-parenting-time presumption described above does not apply as to a party against whom a domestic violence order is being entered, or has already been entered, under KRS 403.315. In other words, if there is a domestic violence order involving one parent, the case does not start from the presumption of equal joint custody with that parent; the court instead makes an individualized best-interests determination, informed in part by the domestic violence factor built into KRS 403.270(2).

Changing a Custody Order Later: Modification

Once a Kentucky court enters a custody decree, the law limits how soon and how easily it can be changed, so that children are not repeatedly pulled between arrangements. Under KRS 403.340(2), no one may file a motion to modify a custody decree earlier than two years after it was entered, unless sworn affidavits show reason to believe that:

• The child's present environment may seriously endanger the child's physical, mental, moral, or emotional health, or
• The custodian has placed the child with a de facto custodian.

After the two-year period has passed, KRS 403.340(3) allows modification only if there has been a change in the circumstances of the child or the custodian, based on facts that arose since the prior decree or that were unknown at the time of the prior decree, and the court finds that modification is necessary to serve the child's best interests. If a court does modify custody, KRS 403.340(5) applies the same rebuttable presumption favoring joint custody and equally shared parenting time to the new decision, subject to the domestic-violence limitation in KRS 403.315.

This two-year rule is one of the most consequential deadlines in Kentucky custody law and can determine whether a parent can even get a modification request heard, so confirm the filing date of your existing decree and how it interacts with these rules before filing anything.

Which Kentucky Court Handles Custody Cases

Divorce and related custody matters in Kentucky are handled in Circuit Court (including Family Court divisions where they exist), consistent with KRS 403.140 and the structure of the Kentucky Court of Justice. The Kentucky Court of Justice website allows you to find the circuit court or circuit court clerk for your county, check court dates, look up a case, and access legal forms.

If Another State, a Tribe, or Another Country Is Involved

Custody cases that cross state or national lines are governed by additional layers of law on top of KRS Chapter 403:

• Interstate jurisdiction: Kentucky's Uniform Child Custody Jurisdiction and Enforcement Act, KRS 403.800-403.880, defines a child's "home state" as the state where the child lived with a parent, or a person acting as a parent, for at least 6 consecutive months immediately before the custody proceeding began (or since birth, for a child under 6 months old). The federal Parental Kidnapping Prevention Act, 28 U.S.C. § 1738A, requires other states to give full faith and credit to a custody order made by the child's home state and bars a second state from modifying that order while the first state retains jurisdiction, which is designed to prevent forum-shopping and conflicting orders.
• Tribal children: The federal Indian Child Welfare Act, 25 U.S.C. §§ 1901-1923, sets minimum standards for removing a Native American child from their family and for foster care, adoption, and termination proceedings. It gives tribes a jurisdictional role, requires notice to the tribe, requires "active efforts" to keep the family together, imposes a heightened burden of proof, and sets placement preferences favoring relatives and tribal homes.
• International abduction: The International Child Abduction Remedies Act, 22 U.S.C. § 9001 et seq., implements the Hague Convention and gives a federal court a remedy to order a child wrongfully removed to, or retained in, the United States returned to their country of habitual residence. It decides return, not the underlying custody dispute.

Military Parents

Under the Servicemembers Civil Relief Act, 50 U.S.C. § 3932, a servicemember whose military duties materially affect their ability to appear in court can obtain a stay of at least 90 days in a civil proceeding, which includes divorce, custody, and support cases. This is meant to protect deployed or active-duty parents from default judgments or being forced to litigate a custody case while unable to participate.

Child Support

Child support in connection with a Kentucky custody or divorce case is handled through the Kentucky Attorney General's Office of Child Support Services, which offers an interactive website where a parent can apply for child support services, estimate a child support obligation, make payments, report address changes, upload court orders and other legal documents, and check payment history.

What You Can Do in Kentucky

1. Identify which Kentucky circuit court (or family court division) has jurisdiction over your case, based on where you and the child live, using the Kentucky Court of Justice's circuit court lookup by county.
2. Gather documentation relevant to the best-interest factors in KRS 403.270(2): school and medical records, evidence of each parent's caregiving involvement, and any documentation of domestic violence findings under KRS 403.720, if applicable.
3. If you are a grandparent or other relative seeking custody, gather evidence of the timing and extent of your caregiving and financial support, since de facto custodian status requires clear and convincing evidence of at least 6 months (child under 3) or 1 year (child 3 or older) as primary caregiver and supporter.
4. If you already have a custody decree and want it changed, check the date it was entered; if it has been less than two years, confirm whether your situation fits the narrow exceptions in KRS 403.340(2) before filing.
5. If your case involves a parent or child living outside Kentucky, a tribal child, a possible international abduction, or a deployed servicemember, flag that immediately, since federal law (the PKPA, ICWA, ICARA, or SCRA) may control alongside Kentucky's statutes.
6. Set up or update child support through the Kentucky Attorney General's Child Support Services website as part of, or separate from, your custody case.
7. Confirm you are reading the current version of any Kentucky statute cited here before relying on it, since the Kentucky Revised Statutes are updated by the General Assembly and by the state's own statute database on an ongoing basis.
