Child Custody in Pennsylvania (2026)

Pennsylvania’s 16 Best Interest Factors

Pennsylvania stands out among states for the specificity and breadth of its statutory best interest analysis. Under 23 Pa.C.S. Section 5328(a), courts must evaluate 16 enumerated factors when making any custody determination. This is one of the most detailed statutory lists in the country, and it shapes every aspect of how custody cases are litigated and decided in the Commonwealth.

The 16 factors are:

1. Which party is more likely to encourage and permit frequent and continuing contact between the child and the other party
2. The present and past abuse committed by a party or member of the party’s household, including any protection-from-abuse orders
3. The parental duties performed by each party on behalf of the child
4. The need for stability and continuity in the child’s education, family life, and community life
5. The availability of extended family
6. The child’s sibling relationships
7. The well-reasoned preference of the child, based on the child’s maturity and judgment
8. Any attempts of a parent to turn the child against the other parent (parental alienation)
9. Which party is more likely to maintain a loving, stable, consistent, and nurturing relationship with the child adequate for the child’s emotional needs
10. Which party is more likely to attend to the daily physical, emotional, developmental, educational, and special needs of the child
11. The proximity of the residences of the parties
12. Each party’s availability to care for the child or ability to make appropriate child-care arrangements
13. The level of conflict between the parties and the willingness and ability of the parties to cooperate with one another
14. The history of drug or alcohol abuse of a party or member of a party’s household
15. The mental and physical condition of a party or member of a party’s household
16. Any other relevant factor

Courts are required to address each factor in their decisions, and appellate courts have overturned custody orders where the trial court failed to adequately analyze all 16 factors. This makes the statutory list not merely a guideline but a binding analytical framework. In practice, parties preparing for a custody hearing should be ready to present evidence on each factor, and the factors collectively provide a transparent roadmap for how the court will reach its decision.

The first factor — which parent is more likely to encourage the child’s relationship with the other parent — is frequently cited by Pennsylvania courts as one of the most important. A parent who attempts to restrict or undermine the child’s relationship with the other parent may find this weighed heavily against them.

Overview of Pennsylvania Custody Law

Pennsylvania custody law is governed by 23 Pa.C.S. Sections 5321 through 5340, a comprehensive statutory framework that prioritizes the best interests of the child above all other considerations. The law recognizes that children benefit from having a meaningful relationship with both parents and structures custody arrangements accordingly — but it does not create a presumption in favor of any particular custody arrangement.

Pennsylvania courts have broad discretion to fashion custody orders that fit the unique circumstances of each family. Whether parents are divorcing, separating, or were never married, the same statutory standards apply. Understanding how the state approaches custody decisions can help parents prepare for what lies ahead.

Types of Custody in Pennsylvania

Pennsylvania law distinguishes between legal custody and physical custody, and each can be awarded on a sole or shared basis.

• Sole legal custody gives one parent the exclusive right to make major decisions about the child’s education, medical care, and religious upbringing.
• Shared legal custody grants both parents the right to participate in these major decisions, regardless of where the child primarily lives.
• Primary physical custody means the child lives with one parent for a majority of the time.
• Shared physical custody divides the child’s time between both parents in a way that allows each to have significant, recurring periods of physical custody.
• Partial physical custody gives a parent the right to take possession of the child for less than a majority of the time.
• Supervised physical custody requires the presence of a third party or an approved agency during a parent’s time with the child.

Courts can combine these categories in various ways. A common arrangement is shared legal custody with primary physical custody to one parent and partial physical custody to the other.

Presumptions and Child Preference

Pennsylvania law does not establish a presumption in favor of either parent or any specific custody arrangement. The court begins each case with a clean slate and builds its decision around the 16 best interests factors.

There is no specific age at which a child may choose which parent to live with. Instead, the court considers the child’s “well-reasoned preference” as one factor among the 16 listed in Section 5328. In practice, older children — particularly teenagers — tend to have their preferences carry more weight, but only when the court finds the preference is based on maturity and sound judgment rather than a desire to avoid rules or discipline. The preference of a child is never the sole determining factor.

Relocation

When a parent with custody wants to move a significant distance, Pennsylvania imposes specific requirements under 23 Pa.C.S. Section 5337. The relocating parent must provide 60 days’ advance written notice to every person who has custody rights. The notice must include the new address, the reasons for the proposed move, and a revised custody schedule.

If the non-relocating parent objects, the court holds a hearing and considers 10 relocation-specific factors, including the nature and quality of the child’s relationship with each parent, the impact on the child’s emotional development, and whether the relocation will enhance the quality of life for both the relocating parent and the child.

The burden of proof in relocation cases depends on the existing custody arrangement. If the parents share custody roughly equally, the relocating parent bears the burden of showing the move serves the child’s best interests. Courts take relocation cases seriously, and a parent who moves without following proper procedure risks sanctions and modification of the custody order.

Mediation

Pennsylvania does not mandate mediation statewide for custody disputes. However, many individual counties — including Allegheny, Chester, and Montgomery — require parents to participate in mediation or a custody conference before the case proceeds to trial. Even in counties without mandatory programs, judges frequently recommend mediation as a way to resolve disputes more efficiently and with less adversarial impact on the family.

Mediation can be particularly effective in Pennsylvania custody cases because the 16-factor analysis gives both parents a clear framework for understanding how a court is likely to rule. A skilled mediator can help parents craft a parenting plan that addresses the court’s concerns while reflecting the family’s actual needs.

Modification of Custody Orders

Either parent may petition the court to modify an existing custody order when there has been a material and substantial change in circumstances that affects the child’s best interests. Common grounds for modification include a parent’s relocation, changes in work schedules, a child’s evolving needs as they grow older, or concerns about safety in one parent’s home.

The court applies the same 16 best interests factors when evaluating a modification request. Pennsylvania courts recognize that children’s needs change over time and that custody arrangements should be flexible enough to adapt — but they also value stability and will not modify orders based on minor or temporary changes.

Steps Parents Can Take

Preparing for a custody case in Pennsylvania starts with understanding the factors the court will evaluate. Parents should document their involvement in the child’s daily life, maintain open communication with the other parent when possible, and avoid any conduct that could be interpreted as undermining the child’s relationship with the other parent.

If you are facing a custody dispute, learning about child custody laws is a practical first step. For personalized guidance on your situation, consider requesting a free consultation with a family law professional who practices in your county.

Frequently Asked Questions

How many best interest factors does Pennsylvania consider?

Under 23 Pa.C.S. Section 5328, Pennsylvania courts must consider 16 specific factors, including which parent is more likely to encourage contact with the other parent, parental duties performed, the child’s sibling relationships, the well-reasoned preference of the child, and any attempts by a parent to turn the child against the other parent.

Does Pennsylvania require mediation in custody cases?

Not statewide, but many individual counties — including Allegheny, Chester, and Montgomery — require parents to participate in mediation or a custody conference before the case proceeds to trial.

How much notice must a relocating parent give?

Under 23 Pa.C.S. Section 5337, the relocating parent must provide 60 days advance written notice to every person with custody rights. The notice must include the new address, the reasons for the move, and a revised custody schedule.

What types of physical custody does Pennsylvania recognize?

Pennsylvania recognizes primary physical custody (majority of time), shared physical custody (significant, recurring time with both parents), partial physical custody (less than majority of time), and supervised physical custody (requiring a third party present). Courts can combine these in various configurations.

What are the 16 best interest factors in Pennsylvania?

The 16 factors under 23 Pa.C.S. Section 5328(a) cover: (1) which parent encourages contact with the other parent, (2) present and past abuse, (3) parental duties performed, (4) need for stability and continuity, (5) availability of extended family, (6) sibling relationships, (7) well-reasoned preference of the child, (8) attempts to turn the child against the other parent, (9) which parent maintains a loving and nurturing relationship, (10) which parent attends to daily needs, (11) proximity of residences, (12) availability to care for the child, (13) level of conflict and willingness to cooperate, (14) history of drug or alcohol abuse, (15) mental and physical condition, and (16) any other relevant factor. Courts must address each factor in their decisions.

Does Pennsylvania favor mothers over fathers in custody cases?

No. Pennsylvania law explicitly does not establish a presumption in favor of either parent. The legislature eliminated the “tender years” doctrine (which historically favored mothers for young children) decades ago. Today, custody decisions are based solely on the 16 best interest factors under 23 Pa.C.S. Section 5328(a), applied equally regardless of which parent is seeking custody. The court’s focus is entirely on the child’s well-being and the demonstrated parenting abilities of each party.

How This Guide Was Researched

This guide was developed through a thorough review of the Pennsylvania Child Custody Act (23 Pa.C.S. Chapter 53), with particular attention to the 16 best interest factors codified in Section 5328(a), the custody types defined in Section 5322, and the relocation provisions in Section 5337. The analysis was cross-referenced with published appellate decisions interpreting the 2011 custody reforms, which replaced the prior case-law-driven framework with a comprehensive statutory structure. Filing procedures and county-specific mediation requirements were confirmed through the Pennsylvania Courts self-representation portal and individual county Court of Common Pleas websites.
