Pennsylvania Custody Factors: Best Interest of the Child

Pennsylvania courts decide child custody by working through the best interest factors listed in 23 Pa.C.S. § 5328(a), and after amendments effective in 2024 and 2025 the statute directs judges to give “substantial weighted consideration” to the factors that affect a child’s safety. The Pennsylvania custody factors in the best interest of the child analysis cover safety, abuse history, each parent’s willingness to cooperate and perform daily parenting duties, the child’s relationships and preferences, and practical questions like distance, work schedules, and health. A judge must address every relevant factor on the record or in a written opinion, and a decision that skips factors without explanation is vulnerable to reversal on appeal.

The Safety-Weighted Factors

Four factors sit above the rest. The statute does not just list them; it tells the court to give them more weight than the other factors whenever they are relevant.¹

The first asks which parent is more likely to keep the child safe, taking into account the home environment, supervision habits, and any history of risk. The second looks at past and present abuse by a party or a household member, including protection-from-abuse orders and sexual-violence protection orders where abuse was actually found. The third, added in 2024, directs the court to review information under Section 5329.1 on indicated or substantiated child-abuse reports and any history with child protective services. The fourth, also new in 2024, covers violent or assaultive behavior by a party, whether or not that behavior resulted in a criminal conviction.²

These safety-weighted factors are the reason the statute was reorganized. In practice, a serious finding under any of them can outweigh factors that otherwise favor the other parent, and it can trigger specific conditions in the custody order itself (discussed below).

Cooperation, Parenting, and the Child’s Daily Life

Two broader factors cover how each parent behaves toward the other parent and toward the child’s day-to-day needs. The amendments folded several older, narrower factors into these.

The cooperation factor asks which parent is more likely to encourage frequent contact between the child and the other parent, so long as that contact is consistent with the child’s safety. It also looks at whether a parent has tried to turn the child against the other parent. Two guardrails are written into the statute. A parent who takes reasonable steps to protect a child from abuse cannot be penalized for being uncooperative. And a child’s negative feelings toward one parent cannot be automatically blamed on the other parent.²

The parenting factor covers the parental duties each parent has performed in the past, whether that parent is willing and able to keep performing them, and how well each parent attends to the child’s daily physical, emotional, developmental, educational, and special needs. The old separate factors about which parent was more likely to maintain a loving relationship and which was more likely to attend to daily needs were consolidated into these two provisions.²

The Remaining Factors

The rest of the analysis addresses practical and relational considerations. None of them individually outweighs the safety-weighted factors, but together they often decide cases where safety is not in dispute.

Stability and continuity: Disruptions to the child’s school, neighborhood, and family routines matter, unless changes are needed to protect the child or a parent from harm.
Sibling and familial relationships: The court tries to keep siblings together and preserve the child’s relationships with extended family.
The child’s well-reasoned preference: Weighted by developmental stage, maturity, and judgment.
Distance between the parents’ homes: If the parents live far apart, shared physical custody may not be workable for a school-age child.
Work schedules and childcare: Each parent’s availability during the day and ability to arrange appropriate childcare when unavailable.
Drug or alcohol abuse: Any history of substance abuse by a parent or household member.
Mental and physical condition: The health of each parent and household members, to the extent it affects the ability to care for the child.
Any other relevant factor: A catch-all that lets the court consider anything else that bears on the child’s welfare.

The judge must address each relevant factor in the custody opinion.¹

How the Child’s Preference Is Weighed

Pennsylvania does not set an age at which a child chooses where to live. Factor (7) asks for the child’s “well-reasoned preference” based on developmental stage, maturity, and judgment. A fifteen-year-old with clear, articulate reasons for wanting to stay in a particular school district carries more weight than a seven-year-old who prefers a parent’s house because it has a bigger TV.²

Judges typically hear from children in private chambers rather than in open court. These in camera interviews let the child speak honestly without the pressure of both parents watching. Even a mature teenager’s wishes can be outweighed if the court finds the preferred arrangement is not safe or is otherwise contrary to the child’s best interests.

When a Criminal Record or Abuse History Changes the Analysis

Section 5329 sits alongside the best interest factors and operates as a safety screen. The court must investigate whether a parent or anyone living in that parent’s home has been convicted of, pleaded guilty to, or pleaded no contest to a list of serious offenses, including criminal homicide, aggravated assault, kidnapping, sexual offenses, and child endangerment. Before granting any form of custody to someone with one of those convictions, the court must find that the person does not pose a threat of harm to the child.³

One conviction is an absolute bar. A parent convicted of first-degree murder of the child’s other parent cannot receive any form of custody unless the child is old enough to consent.³

If the court awards custody to someone with a qualifying offense, it may order ongoing evaluations to monitor rehabilitation and the child’s well-being. A later evaluation showing a threat of harm lets the court schedule a hearing to modify the order.³

Disclosure is not optional. Every person who files a custody complaint, modification petition, or contempt petition must file a Criminal Record / Abuse History Verification form at the same time, covering themselves and every member of their household. The other party then has to file their own form no later than one day before their first in-person court contact, or within 30 days of being served, whichever comes first.⁴ The form requires disclosure of convictions, guilty pleas, no-contest pleas, pending charges, and juvenile adjudications for dozens of listed offenses, along with protection-from-abuse orders and any history of child abuse under the Protection from Abuse Act. The duty continues: for as long as the child remains under the court’s jurisdiction, both parents must file an updated form within five days of any change in circumstances or five days before any new court proceeding.⁵

Safety Conditions in the Order Itself

When the court finds a history of abuse or a present risk of harm but still awards custody to the offending party, the order must include specific safety conditions and explain why that arrangement is in the child’s best interest. The conditions can include professional or nonprofessional supervised visitation, limits on the hours or times of day physical custody is allowed, and completion of a batterer’s intervention or harm-prevention program. If supervised contact is ordered, the restricted parent can later petition for a review of whether supervision is still necessary.⁶

How a Judge Applies These Factors

After weighing the factors, the court chooses an arrangement built from two separate questions. Legal custody is the right to make major decisions for the child, covering education, medical care, and religion. Physical custody is the actual day-to-day care and control. Each can be shared or awarded to one parent, and physical custody comes in several gradations: shared, primary, partial, sole, or supervised.⁶

A judge can mix and match. One parent might receive primary physical custody while both share legal custody, which is a common outcome. Whatever the result, the court must explain on the record or in a written opinion why it chose the arrangement it did, and that explanation has to walk through the relevant best interest factors.⁶

What Can Reopen the Factor Analysis Later

Custody orders are not permanent. When circumstances change meaningfully, either parent can petition to modify the arrangement. Pennsylvania courts generally require the petitioner to show a material change in circumstances before reopening the analysis. If that threshold is met, the court reevaluates the case under the same best interest factors from Section 5328.

The kind of change that qualifies is context-dependent. Examples include a parent’s relocation, a significant change in a parent’s work schedule, evidence of substance abuse or domestic violence that was not previously before the court, or a child’s evolving needs as they age. A parent who files a modification petition without a genuine change in circumstances risks being ordered to pay the other parent’s attorney fees.

Enforcement feeds back into the same analysis. When one parent willfully violates a specific provision of the custody order, the other parent can file a Petition for Civil Contempt for Disobedience of a Custody Order. The court has broad discretion over the remedy: makeup custody time, schedule modifications, attorney fees, and in serious cases a change in primary custody. Repeated or egregious violations send a strong signal about a parent’s willingness to cooperate, which feeds directly back into factor (2.3).²
