Custody questions are stressful for any family, but they can feel especially confusing when parents were never married. In Pennsylvania, unmarried parents often ask: Who has custody? Do fathers have rights? What does the court look at?
This article explains custody laws in PA for unmarried parents in a simple, engaging way, so everyday parents understand their rights and responsibilities—and legal professionals have a clear, educational resource to share.
Does Marriage Matter in Pennsylvania Custody Law?

In Pennsylvania, custody decisions are based on parent-child relationships, not whether the parents were married.
However, parentage must be legally established before both parents have equal standing in court.
Who Has Custody at Birth in Pennsylvania?
The Default Rule
When a child is born to unmarried parents in Pennsylvania:
- The mother has automatic legal and physical custody
- The father does not have automatic custody or visitation rights
This doesn’t mean fathers lack rights—it means the law requires paternity to be established first.
Establishing Paternity in Pennsylvania
Before an unmarried father can seek custody or visitation, paternity must be legally recognized.
Ways to Establish Paternity
- Voluntary Acknowledgment of Paternity
- Signed by both parents (often at the hospital)
- Gives the father legal status
- Court Order
- Requested through family court
- May involve DNA testing
Once paternity is established, the father can:
- Request custody or shared custody
- Seek visitation
- Be required to pay child support
Types of Custody in Pennsylvania
Pennsylvania recognizes several custody arrangements:
- Legal Custody
- The right to make major decisions
- Includes education, healthcare, and religion
- Physical Custody
- Where the child lives most of the time
Physical custody can be:
- Primary
- Shared
- Partial
- Supervised (in safety-related cases)
How Pennsylvania Courts Decide Custody
Pennsylvania courts decide custody based on the best interests of the child.
Judges consider multiple factors, including:
- Which parent is more likely to encourage a relationship with the other parent
- Past caregiving roles
- Stability of each home
- Mental and physical health of each parent
- Any history of abuse or neglect
- The child’s safety and emotional needs
The court does not favor mothers over fathers once paternity is established.
Do Unmarried Fathers Have Equal Rights in PA?
Yes—after paternity is established.
Once legally recognized, unmarried fathers can:
- Request shared or primary custody
- Seek joint legal custody
- Ask for modifications in the future
Custody decisions are based on parenting ability, not marital status or gender.
Visitation Rights for Unmarried Parents
If one parent has primary custody, the other parent usually receives:
- Scheduled visitation
- Weekend and holiday time
- Phone or video contact
Visitation may be supervised if:
- There are safety concerns
- Abuse or substance issues are present
- The child’s well-being is at risk
Child Support and Custody Are Separate Issues
A common misunderstanding is that:
- Paying child support guarantees visitation
- Not paying child support cancels visitation
In Pennsylvania:
- Custody and child support are separate legal matters
- A parent cannot deny custody time due to unpaid support
- Enforcement happens through the court, not the parents
Can Custody Orders Be Changed?
Yes. Pennsylvania allows custody modifications when:
- There is a significant change in circumstances
- The change benefits the child
Examples include:
- Relocation
- Changes in work schedules
- Health or safety concerns
- The child’s evolving needs
