Pennsylvania Custody & Parenting
Current, source-linked Pennsylvania custody terminology and rules without imported out-of-state formulas.
Pennsylvania terminology
Legal custody
The right to make major decisions for the child (medical, religious, educational).
Physical custody
Where the child actually lives and receives day-to-day care — sole, primary, shared, partial, or supervised.
Shared / primary / partial custody
Shared (each has significant time), primary (majority of time), or partial (less than a majority).
Best interests
The standard; decided on all relevant factors with substantial weight given to the child's safety (23 Pa.C.S. § 5328).
Core rules
- There is no presumption for or against either parent in a custody action between parents (23 Pa.C.S. § 5327)
- Custody is decided on the child's best interests by considering all relevant factors (23 Pa.C.S. § 5328)
- The court gives substantial weight to safety-related factors; no single factor is determinative
- No party receives a preference based on gender
- There is no fixed 50/50 presumption and no overnight formula that converts a schedule into a custody right
- In contested cases the court may require each party to file a parenting plan (23 Pa.C.S. § 5331)
Support and modification cautions
Pennsylvania uses the Income Shares model for child support — not a flat percentage of one parent's income. The court combines both parents' net income and reads the basic obligation from the schedule (Pa.R.C.P. 1910.16), adjusted for shared custody time (40%+ overnights) and add-ons. A custody order may be modified upon petition when it serves the child's best interests, typically on a substantial change in circumstances.
Always confirm current local forms, fees, and filing procedure with the Pennsylvania Court of Common Pleas / family court clerk handling your case.
