Form 4: Modify What the Court Already Ordered
Pennsylvania's Form 4 petition to modify a custody order is for parents who need fresh order language after material change. County Courts of Common Pleas still run intake, so verify packets and channels locally. This is not the initial complaint lane and not civil contempt unless compliance with existing lines is the whole fight. Pick one job per filing.

| Modification-shaped facts | Contempt-shaped facts |
|---|---|
| Life moved: school zone, relocation math, care collapse, schedule impossible. | Clause is readable; same misses repeat; you can quote the paragraph. |
| You need new paragraphs, not just anger at the other parent. | You need order-matched proof and a dated log of non-compliance. |
Weak modify tells
- "I deserve more time" without a week map or dated change anchors.
- Recycled 2018 drama with no 2026 line tied to the child schedule.
- Asking the court to fix the other parent instead of naming concrete order edits.

Form 4 questions
Why is Form 4 different from an initial custody complaint?
Form 4 assumes an existing custody order and asks the Court of Common Pleas to modify it based on changed circumstances and the child's needs. Writing it like a brand-new introduction signals the wrong procedural story.
How do I know I need modification instead of contempt?
Contempt centers on clear order language someone will not follow. Modification centers on new facts that make old language a bad fit. If your draft is mostly missed Tuesdays under a specific paragraph, you may be documenting enforcement before you rewrite.
What county steps trip parents up?
Current PDF versions, filing channels, copies, service, and local procedural add-ons. Treat the county checklist as part of the petition, not a postscript.
