Pennsylvania Divorce Laws: The Complete Guide

Pennsylvania is a no-fault divorce state with two main paths: mutual consent under 23 Pa.C.S. § 3301(c), available 90 days after the divorce complaint is filed and served, and a one-year separation divorce under § 3301(d) when one spouse will not consent. Six fault grounds also remain available under § 3301(a).

This guide explains every stage of the divorce process in PA: the legal grounds, the six-month residency rule, the step-by-step filing procedure, how property and support are decided, and how practice differs in Philadelphia, Bucks, and Montgomery Counties. Our divorce lawyers handle cases throughout Philadelphia, Bucks, and Montgomery Counties.

Grounds for Divorce in Pennsylvania

No-Fault Divorce: The Two Main Paths

Mutual consent, § 3301(c). If both spouses agree the marriage is irretrievably broken, each signs an affidavit of consent after a 90-day waiting period that begins when the complaint is filed and served. This is the fastest route and the foundation of most uncontested divorces in PA.

Irretrievable breakdown, § 3301(d). If one spouse refuses to consent, the other may proceed after the parties have lived separate and apart for at least one year. The one-year period applies to separations that began after December 5, 2016; older separations require two years. Spouses can be “separate and apart” while still living under the same roof if the marital relationship has ended.

The Six Fault Grounds, § 3301(a)

Fault divorce still exists, though it is rarely the practical choice. The statute lists six grounds, each requiring proof that the filing spouse is “innocent and injured”:

Willful and malicious desertion for one or more years
Adultery
Cruel and barbarous treatment endangering life or health
Bigamy
Imprisonment for two or more years upon conviction of a crime
Indignities that render the innocent spouse’s condition intolerable and life burdensome

A separate ground, § 3301(b), covers institutionalization for a mental disorder lasting at least 18 months. Fault cases require hearings and witness testimony, which adds time and expense, so most clients who could plead fault still proceed no-fault.

Residency Requirement: Six Months

Under 23 Pa.C.S. § 3104(b), at least one spouse must have been a bona fide resident of Pennsylvania for the six months immediately before filing. Only one spouse needs to meet the requirement, and it does not matter where the marriage took place. A PA driver’s license, lease, voter registration, or employment records help establish residency if it is questioned.

How to File for Divorce in PA: Step by Step

File the complaint. The divorce complaint is filed in the appropriate county, usually where the defendant lives, along with counts for any economic claims: equitable distribution, alimony, counsel fees. Claims not raised before the decree are generally waived forever.
Serve your spouse. The complaint must be served within 30 days of filing, or 90 days if the defendant lives outside Pennsylvania, by personal service or certified mail with restricted delivery.
Establish grounds. In a § 3301(c) case, both spouses sign affidavits of consent once the 90 days have run. In a § 3301(d) case, the filing spouse submits an affidavit of one-year separation, and the other spouse has a limited window to file a counter-affidavit disputing the separation date or the breakdown of the marriage.
Resolve the economic claims. The parties exchange financial information, value assets, and either negotiate a marital settlement agreement or proceed to a hearing before a divorce master or hearing officer.
Obtain the decree. Once grounds are established and economic claims are settled or decided, a praecipe to transmit the record is filed and the court enters the divorce decree.

Equitable Distribution of Marital Property

Pennsylvania divides marital property under 23 Pa.C.S. § 3502 by equitable distribution, which means fair, not automatically 50/50. Marital property generally includes everything acquired by either spouse from the wedding date to the date of separation, regardless of whose name is on the title. Separate property includes premarital assets, gifts and inheritances to one spouse, and property acquired after separation, although the increase in value of separate property during the marriage is marital.

Section 3502(a) lists 13 factors the court weighs, including the length of the marriage, each spouse’s age, health, income, and employability, contributions as a homemaker, the standard of living during the marriage, tax consequences, and which parent will serve as custodian of minor children. Marital misconduct is not a factor in property division. Read more about property settlements and what a divorce costs in PA.

Alimony, APL, and Spousal Support

Pennsylvania has three distinct support concepts. Spousal support can be paid after separation but before a divorce is filed. Alimony pendente lite (APL) is paid while the divorce is pending to keep the litigation on equal footing. Both are calculated under the statewide guideline formula in the Pa.R.C.P. 1910.16 series. Post-divorce alimony is different: it is a discretionary remedy the court awards only where reasonable and necessary, based on the 17 factors in § 3701. Our comparison of alimony vs. spousal support in PA explains the differences in detail.

Child Custody and Child Support

Custody is decided separately from the divorce under 23 Pa.C.S. §§ 5321-5340. Courts weigh the best-interest factors in § 5328(a), giving substantial weighted consideration to the factors that affect the child’s safety under Act 8 of 2024, known as Kayden’s Law. Act 11 of 2025 then consolidated the former 16-factor list into a shorter set for cases filed on or after August 29, 2025. Child support follows the income-shares guidelines in the Pa.R.C.P. 1910.16 series, based on both parents’ net monthly incomes and the custody schedule. If children are involved, speak with a custody lawyer early, because custody and support run on their own tracks and deadlines.

County Differences: Philadelphia, Bucks, and Montgomery

The statutes are statewide, but procedure is local. In Philadelphia County, divorces are filed with the Clerk of Family Court, and the filing fee is roughly $334 plus surcharges. In Bucks County, complaints are filed with the Prothonotary in Doylestown, where the 2026 fee is about $398 before added counts. Montgomery County filings go through the Prothonotary in Norristown, typically in the $285 to $350 range depending on the counts included. Each county also has its own local rules for scheduling, conciliation, and master’s hearings, and fees change regularly, so confirm with the prothonotary before filing. We maintain offices in Feasterville, Doylestown, Norristown, and Philadelphia, so filings and hearings are handled locally.

Common Mistakes to Avoid

Failing to raise equitable distribution or alimony before the decree, which permanently waives those claims
Miscounting the separation date in a § 3301(d) case, or missing the counter-affidavit deadline
Assuming property titled in one name is safe from distribution
Signing an affidavit of consent or settlement agreement without understanding retirement accounts, QDROs, and tax consequences
Moving out without a written custody arrangement
Expecting a strict 50/50 split of assets

Frequently Asked Questions

Is Pennsylvania a no-fault divorce state?

Yes. Most Pennsylvania divorces proceed no-fault, either by mutual consent under § 3301(c) or after one year of separation under § 3301(d). Fault grounds still exist but are rarely the practical choice.

How long do you have to be separated before divorce in PA?

One year, if the separation began after December 5, 2016 and one spouse will not consent. Separations that began earlier require two years. No separation period is required for a mutual consent divorce.

How long does a divorce take in Pennsylvania?

A mutual consent divorce with no contested economic issues can finish in roughly four to six months. Contested cases involving property, alimony, or a one-year separation commonly take a year or longer.

Do both spouses have to agree to a divorce in PA?

No. If one spouse refuses to consent, the other can still obtain a divorce under § 3301(d) after one year of separation, or by proving a fault ground under § 3301(a).

How is property divided in a Pennsylvania divorce?

By equitable distribution under § 3502. The court weighs 13 statutory factors to reach a fair division of marital property, which is not necessarily an equal split. Marital misconduct is not considered.

Does adultery affect a Pennsylvania divorce?

Yes, in limited ways. Adultery is a fault ground under § 3301(a), it can defeat a claim for spousal support, and it is weighed as marital misconduct among the 17 alimony factors in § 3701. It is not a factor in dividing marital property.

Can I file for divorce in PA without a lawyer?

Yes, self-representation is allowed, and the state courts publish forms. But economic claims that are not properly raised are waived at the decree, so mistakes in a do-it-yourself filing can be permanent.

Where do I file for divorce in Pennsylvania?

Generally in the county where the defendant lives, though the parties can agree to another county. At least one spouse must have lived in Pennsylvania for six months before filing under § 3104(b).
