Filing for custody in Pennsylvania costs roughly $100 to $350 in court filing fees, with the exact amount depending entirely on which county you file in. Philadelphia County charges $107.13 to open a custody case. Chester County charges $215.25. Allegheny County charges $345.75 when no other filing fees have already been paid in the case. Those are just the court’s numbers. Once you add service of process, a required parenting seminar, and any attorney involvement, a straightforward case commonly runs into the thousands, and a contested one into the tens of thousands.
What the County Charges to File
You pay the filing fee at your county’s Prothonotary or Office of Judicial Records when you submit the custody complaint. Each county sets its own base rate, so the price is local. The Philadelphia, Chester, and Allegheny figures above show how wide the spread runs across the state, and the only reliable way to know your exact cost is to call your county’s filing office before you go.
Some counties layer on local administrative charges. Dauphin County adds a $150 administrative fee payable to the Prothonotary at the time of filing. Statewide surcharges apply to most filings as well, including a Judicial Computer System fee and an Access to Justice fee established under the Judicial Code. Together those surcharges add roughly $10 to $16 to a filing.
If you already have a custody order and only need to change it, the filing fee is much lower. Luzerne County, for example, charges $27 to file a petition for modification, contempt, or special relief.
Serving the Other Parent
After you file, you have to formally deliver copies of the complaint to the other parent. Pennsylvania Rule of Civil Procedure 1930.4 governs service in domestic relations cases and allows either a sheriff or any competent adult to hand-deliver the paperwork, which is broader than the rule for general civil cases. You have 30 days from filing to complete service on a defendant inside Pennsylvania, and 90 days if the other parent lives out of state.
Sheriff service fees vary by county and generally run $50 to $150, depending on mileage and the number of attempts. Private process servers charge in the same range. Whoever serves the papers must file proof of service showing the date, time, location, and manner of delivery. If the other parent is dodging service, costs climb because you may need multiple attempts or court approval for alternative methods like service by publication.
The Parenting Seminar
Most Pennsylvania counties require both parents to attend a court-approved parenting seminar early in the case. Names differ by county. Montgomery County calls its program “The Children Come First,” a 90-minute workshop costing $60 per parent. Lancaster County runs a four-hour seminar called “Focus on Children.” Fees around the state generally fall between $40 and $100 per person.
You usually have to complete the seminar before the court schedules your first custody conference. The order attached to your complaint typically names the program, sets a deadline, and explains how to register. Skipping it can delay your case or draw sanctions.
Attorney Fees
Legal representation is the single biggest expense in a custody case. Pennsylvania family law attorneys generally charge hourly rates between $275 and $375, and rates in Philadelphia and its suburbs sometimes run higher. Most require an upfront retainer, commonly $3,000 to $5,000, which the lawyer draws from as they work the case. When the retainer runs out, you replenish it or get billed monthly.
For a straightforward case where the parents agree on most issues and the attorney’s role is limited to drafting documents and attending one or two conferences, total fees can stay under $5,000. Contested cases are different. If you’re headed to trial, the attorney will bill for depositions, witness preparation, motion practice, and court appearances. Total legal fees in contested custody litigation regularly exceed $15,000, and go much higher when psychological evaluations or expert testimony come into play.
Some attorneys offer unbundled services, meaning you hire them for a specific task rather than the whole case. You might pay a flat fee to have them draft your complaint, coach you for a conference, or represent you at a single hearing. Every phone call, email, and text to your attorney is typically billed in six-minute increments, so grouping questions into fewer communications is one of the easiest ways to hold costs down.
Evaluations, Guardians ad Litem, and Supervised Visits
When parents cannot agree and the case involves serious concerns about a child’s wellbeing, the court may order a custody evaluation. A psychologist or licensed evaluator interviews both parents, observes them with the child, reviews records, and writes a report recommending an arrangement. Court-appointed evaluators typically charge $1,000 to $2,500. Private evaluators with specialized credentials can charge $10,000 to $15,000 or more for a comprehensive evaluation. The court decides how to split the cost, and there is no universal formula. Some judges divide it evenly; others assign a larger share to the parent with more financial resources or the parent who requested the evaluation.
A guardian ad litem is a separate expense. If the court appoints an attorney to represent the child’s interests, the order specifies how the parents share the cost. Pennsylvania’s rules give the court discretion to apportion GAL fees and do not cap or standardize the amount. In a case that goes to trial, GAL fees of several thousand dollars are common.
If the court orders supervised visitation, the parent who needs supervision usually pays for it. Professional supervision through a visitation center runs $30 to $150 per hour, and some facilities charge additional intake or administrative fees. Centers serving low-income families may offer sliding-scale pricing.
If You Cannot Afford the Fees
If paying the filing fee is out of reach, Pennsylvania Rule of Civil Procedure 240 lets you petition to proceed in forma pauperis, which waives court costs and filing fees. There is no specific income cutoff. The standard is whether you lack the financial resources to pay litigation costs, and the court decides based on what you disclose.
The petition requires a sworn affidavit covering your financial situation: employment and monthly wages, other income such as Social Security, disability payments, pensions, unemployment compensation, and public assistance, and property you own, including cash, bank accounts, real estate, and vehicles. You also have to state that you cannot obtain funds from family or associates to cover costs. The court must act on your petition within 20 days.
A granted petition wipes out filing fees, surcharges, and sheriff service costs. It does not cover attorney fees or evaluation costs. Most Prothonotary offices stock the IFP forms, and they are also available through the Pennsylvania Unified Judicial System’s website.
