Kentucky Child Custody: Best Interest Factors

Kentucky made national headlines in 2018 when it became the first state in the country to establish a presumption of equal parenting time in custody cases. Under KRS 403.270, Kentucky courts now start from the position that joint custody and equal time with both parents is in the child’s best interest — unless evidence shows otherwise. This landmark change reshaped how custody is determined in the Commonwealth and gave both parents a stronger starting point in custody disputes.

This article explains how Kentucky’s best interest factors work, the impact of the equal parenting time presumption, the different types of custody recognized under Kentucky law, and how special circumstances like domestic violence and de facto custodian status affect the analysis.

For a general overview of how custody is determined across the country, see our guide on how child custody is determined.

The Best Interest Standard Under KRS 403.270

Like every state, Kentucky requires courts to make custody decisions based on the best interest of the child. Under KRS 403.270(2), the court must consider all relevant factors, including:

(a) The Wishes of the Parents

The court considers each parent’s desires regarding custody. While a parent’s preference is relevant, it does not control the outcome. The court weighs each parent’s wishes alongside all other factors.

(b) The Wishes of the Child

The court considers the wishes of the child as to their custodian. Kentucky does not set a specific age at which a child’s preference becomes controlling. Instead, the court evaluates the child’s maturity, reasoning, and whether the preference appears genuine. Older children — generally those 12 and above — tend to have their preferences given more weight, but the court is not bound by the child’s stated preference.

(c) Interaction With Parents, Siblings, and Others

The court examines the child’s interaction and interrelationship with parents, siblings, and any other person who may significantly affect the child’s best interest. This includes the quality of the parent-child bond, the child’s relationships with siblings, and the involvement of extended family members or other caregivers.

(d) The Child’s Adjustment

The court evaluates the child’s adjustment to home, school, and community. Stability matters. A child who is thriving in their current school, has strong friendships, and is well-adjusted at home benefits from continuity. Courts are generally reluctant to disrupt a living arrangement that is working well.

(e) Mental and Physical Health

The mental and physical health of all individuals involved is considered. This includes both parents and the child. A parent’s health condition is relevant only to the extent it affects their ability to care for the child. A manageable health condition that does not impair parenting is unlikely to weigh against a parent.

(f) Information About Domestic Violence

The court considers domestic violence and abuse, as discussed in detail below. This factor carries significant weight and can override other considerations.

(g) The Extent of the Child’s Contact With Both Parents

The court examines the extent to which the child has been cared for, nurtured, and supported by the parents and the nature and extent of each parent’s past involvement. A parent who has been consistently and actively involved in the child’s daily life — attending school events, managing medical care, helping with homework — generally fares well on this factor.

(h) Intent of Either Parent to Relocate

If either parent plans to relocate their primary residence, the court considers the impact this would have on the child’s relationship with both parents.

The Equal Parenting Time Presumption

In 2018, Kentucky enacted House Bill 528, which amended KRS 403.270 to create a rebuttable presumption that joint custody and equally shared parenting time is in the child’s best interest. Kentucky was the first state in the nation to adopt this presumption.

Under the presumption:

• The court must start from the position that both parents should have equal time with the child.
• Either parent can rebut the presumption by presenting evidence that equal parenting time is not in the child’s best interest.
• The court still evaluates all of the best interest factors listed above. The presumption shifts the starting point, but it does not guarantee a 50/50 outcome.

The practical effect of this law is significant. Before 2018, a parent seeking equal time had to convince the court that such an arrangement was appropriate. Now, the parent opposing equal time must demonstrate why it should not apply. This shift in the burden of proof changed the dynamics of custody negotiations statewide.

Common grounds for rebutting the presumption include:

• Domestic violence or child abuse
• Substance abuse by one parent
• Geographic distance that makes equal time impractical
• The child’s established routine, if equal time would cause significant disruption
• A parent’s work schedule that prevents meaningful caregiving during their parenting time
• Parental conflict so severe that frequent transitions harm the child

Types of Custody in Kentucky

Kentucky recognizes several forms of custody:

Legal Custody

Legal custody refers to the right and responsibility to make major decisions about the child’s life, including education, healthcare, and religious upbringing. Legal custody can be:

• Joint legal custody — Both parents share decision-making authority. This is the most common arrangement in Kentucky, and the 2018 presumption favors it.
• Sole legal custody — One parent has exclusive decision-making authority. Courts typically award sole legal custody only when joint decision-making has proven unworkable due to extreme conflict, domestic violence, or other serious concerns.

Physical Custody

Physical custody refers to where the child lives and the day-to-day care of the child. Physical custody arrangements include:

• Joint physical custody — The child spends significant time living with both parents. Under Kentucky’s presumption, the starting point is an equal or near-equal split.
• Primary physical custody — The child lives primarily with one parent, and the other parent has a visitation schedule (referred to as parenting time in Kentucky).

Temporary Custody

During the divorce or custody proceedings, the court may enter temporary custody orders under KRS 403.280 to maintain stability while the case is pending. Temporary orders remain in effect until the court issues a final custody determination.

Domestic Violence Considerations

Domestic violence is one of the most heavily weighted factors in Kentucky custody cases. Under KRS 403.270(2)(f), the court must consider information relating to domestic violence and abuse as defined in KRS 403.720.

When domestic violence is present, the court evaluates:

• The nature, severity, and frequency of the violence
• Whether the violence was directed at the child, the other parent, or both
• The impact on the child’s physical and emotional well-being
• Whether the abusive parent poses an ongoing risk
• Whether the abusive parent has completed a domestic violence intervention program

Kentucky law also provides that the court shall not consider conduct of a proposed custodian that does not affect the relationship to the child (KRS 403.270(1)). However, domestic violence is directly relevant because it affects the child’s safety and well-being — even when the violence is directed at the other parent rather than the child.

In cases involving domestic violence, the equal parenting time presumption can be overcome. The court may restrict the abusive parent’s custody or visitation, require supervised visitation, or impose other protective conditions.

De Facto Custodian Rights

Kentucky is one of the few states that provides a statutory framework for de facto custodians — non-parents who have been the child’s primary caregiver. Under KRS 403.270(1)(a), a de facto custodian is a person who has been the primary caregiver and financial supporter of a child and has been in that role for:

• Six months or more if the child is under age three
• One year or more if the child is age three or older

A de facto custodian has standing to seek custody on the same footing as a parent. The court applies the same best interest factors to determine whether custody with the de facto custodian serves the child’s best interest. This provision is particularly important for grandparents, stepparents, and other relatives who have taken on a primary parenting role.

The de facto custodian doctrine reflects Kentucky’s recognition that the child’s bond with their primary caregiver matters, regardless of biological relationship. However, de facto custodian status must be established through evidence — simply spending time with the child is not sufficient. The person must demonstrate that they were the primary caregiver and financial supporter for the required period.

Parenting Plans and Schedules

In most Kentucky custody cases, the court requires the parents to submit a parenting plan or time-sharing schedule that specifies:

• The regular parenting time schedule (weekdays, weekends, overnight allocations)
• Holiday and vacation schedules
• Transportation arrangements for exchanges
• Communication protocols between the child and the non-custodial parent
• How major decisions will be made (in joint custody arrangements)
• Procedures for resolving future disputes

Given the equal parenting time presumption, many Kentucky parenting plans now reflect a 50/50 schedule. Common arrangements include alternating weeks, a 2-2-3 rotation, or a 5-2-2-5 schedule. The specific schedule depends on the parents’ work schedules, the child’s school, and geographic proximity.

Modifying Custody Orders

Under KRS 403.340, a custody order can be modified if the court finds that a change in circumstances has occurred since the original order and that modification is in the child’s best interest. Kentucky imposes additional restrictions on modification requests:

• Within the first two years after a custody order, modification requires proof that the child’s present environment may endanger their physical, mental, or emotional health.
• After two years, the standard is whether there has been a material change in circumstances and whether modification serves the child’s best interest.

These restrictions exist to promote stability and discourage repeated litigation over custody.

What to Do Next

If you are involved in a custody dispute in Kentucky, take these steps:

1. Understand the presumption. Know that Kentucky law starts from the position of equal parenting time. If you support equal time, the presumption works in your favor. If you believe equal time is not appropriate, prepare specific evidence to explain why.
2. Document your involvement. Keep records of your participation in your child’s daily life — school events, medical appointments, extracurricular activities, and daily care. Evidence of consistent, active parenting carries significant weight.
3. Address any domestic violence. If you are a victim of domestic violence, document the abuse and seek a protective order. If allegations are made against you, take them seriously and address them with legal counsel.
4. Prepare a parenting plan. Draft a proposed schedule that reflects the child’s needs and your ability to provide care. A well-thought-out parenting plan demonstrates your commitment to co-parenting.
5. Consult a Kentucky family law attorney. Kentucky’s equal parenting time presumption, best interest factors, and de facto custodian doctrine create a unique custody framework. Schedule a free consultation to discuss your case with an experienced family law attorney.

Frequently Asked Questions

Does Kentucky always award 50/50 custody?

No. Kentucky’s equal parenting time presumption is a starting point, not a guaranteed outcome. The court can deviate from equal time based on the best interest factors, including domestic violence, geographic distance, the child’s established routine, and each parent’s ability to provide care. The presumption means the parent opposing equal time must present evidence showing why it is not appropriate.

At what age can a child decide which parent to live with in Kentucky?

Kentucky does not set a specific age at which a child can choose their custodial parent. The court considers the child’s wishes as one of several best interest factors, weighing them based on the child’s maturity and reasoning. Older children tend to have their preferences given more weight, but the court is never bound by the child’s stated preference.

Can grandparents get custody in Kentucky?

Yes, under certain circumstances. A grandparent who qualifies as a de facto custodian — having served as the child’s primary caregiver and financial supporter for the required period — has standing to seek custody. Additionally, under KRS 405.021, grandparents may petition for visitation rights if the court finds it is in the child’s best interest.

What is a de facto custodian in Kentucky?

A de facto custodian is a person who has been the child’s primary caregiver and financial supporter for six months or more (if the child is under three) or one year or more (if the child is three or older). A de facto custodian has the right to seek custody and is evaluated under the same best interest standard that applies to parents.

How do I modify a custody order in Kentucky?

To modify custody, you must file a motion with the court and demonstrate a material change in circumstances since the original order. Within the first two years, the standard is higher — you must show that the child’s current environment may endanger their health. After two years, the standard is a change in circumstances plus a showing that modification serves the child’s best interest.
