To start the divorce process in Pennsylvania, one spouse must have lived in the state for at least six months, and then you file a divorce complaint, along with a Notice to Defend and Claim Rights, in the Court of Common Pleas of the right county, pay the filing fee, and arrange formal service on your spouse. Before any of that, you choose your legal grounds, because that choice sets the timeline and dictates which affidavits you will eventually sign.
Residency and Where to File
Pennsylvania courts will not hear the case unless at least one spouse has been a bona fide resident of the Commonwealth for the six months immediately before filing.1Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 31 – Section 3104 Where you married and where your spouse lives now do not matter for this threshold.
Once residency is satisfied, Pennsylvania Rule of Civil Procedure 1920.2 lets you file in the county where either spouse currently resides, or in any county both parties agree to in writing.2Pennsylvania Code and Bulletin. 231 Pa. Code Rule 1920.2 – Venue Filing in the wrong county will not kill the case, but it can force a transfer and add weeks. If you and your spouse live in different counties, think about which courthouse is more practical for later hearings.
Choosing Your Grounds
Pennsylvania recognizes three main categories of grounds: no-fault by mutual consent, no-fault based on a one-year separation, and fault. Most cases proceed no-fault because it is faster and does not require proof of misconduct.
No-Fault by Mutual Consent
Both spouses agree the marriage is irretrievably broken. A 90-day clock runs from the date of filing (the day the prothonotary stamps the complaint, not the day your spouse is served). After the 90 days, each spouse signs an affidavit of consent and the court can enter the decree.3Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 33 – Section 3301
No-Fault Based on One-Year Separation
When one spouse will not consent, the other can still proceed under Section 3301(d) by showing the marriage is irretrievably broken and the couple has lived separate and apart for at least a year. If the other spouse denies the separation, the court holds a hearing on the issue.3Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 33 – Section 3301 Separate and apart does not always mean separate homes; courts have found the requirement satisfied when spouses stayed under one roof but ran completely separate lives.
Fault-Based Grounds
Fault requires the “innocent and injured” spouse to prove specific misconduct. The recognized grounds are desertion for a year or more without reasonable cause, adultery, cruel treatment endangering life or health, bigamy, imprisonment on a sentence of two or more years, and indignities amounting to a continuing pattern that made life intolerable.3Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 33 – Section 3301 Fault cases take longer because they require a hearing and evidence, but they avoid a separation period, and proven fault can occasionally affect alimony or property outcomes.
One narrow boundary worth knowing: Pennsylvania also allows a divorce when a spouse has been confined to a mental institution for at least 18 months before filing with no reasonable prospect of discharge in the next 18 months, established by a certificate from the institution’s superintendent and a treating physician’s statement.3Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 33 – Section 3301 This is a separate ground, not a form of fault or mutual consent.
A Practical Hedge
If there is any doubt your spouse will cooperate, plead mutual consent under Section 3301(c) and irretrievable breakdown under Section 3301(d) at the same time. Pennsylvania allows it, and it gives you a fallback if consent falls through after the 90 days.
Preparing the Complaint
The complaint is the document that formally starts the case. It identifies both spouses, states when and where the marriage took place, and specifies the grounds you are pursuing. It also needs to include any related claims you want the court to decide, such as equitable distribution of property, alimony, or custody, because failing to raise certain claims before the decree is entered can forfeit your right to bring them later.
Every Pennsylvania divorce complaint must be paired with a Notice to Defend and Claim Rights. This court-approved form warns your spouse that a divorce action has been filed and that a decree may be entered in their absence, and that they could lose rights to alimony, property division, and attorney’s fees if they do not file a timely claim.4Pennsylvania Courts. Form 1 – Notice to Defend and Divorce Complaint The forms are available from the prothonotary’s office at your county’s Court of Common Pleas or from the Pennsylvania Courts website.
Before you fill anything out, pull together your marriage certificate, both spouses’ full legal names and current addresses, the date and place of marriage, and the grounds you plan to assert. If you have children, their names and dates of birth. Financial records like pay stubs, bank statements, retirement account statements, and mortgage documents are not required for the complaint itself, but they will matter as soon as property division and support come up, so gathering them now saves scrambling later.
Filing and Paying the Fee
Take the completed complaint and Notice to Defend to the prothonotary’s office at the Court of Common Pleas in your chosen county. The prothonotary stamps the documents, assigns a docket number, and the case is officially open. Filing fees vary by county and often run above $300. Philadelphia County’s 2025 schedule, for example, lists $334.73 to commence a divorce action, spread across base fees, automation fees, a judicial education surcharge, and other line items.5Philadelphia Courts. Office of Judicial Records Fee Schedule Call your county’s prothonotary ahead of time to confirm the exact amount and accepted payment methods.
If you cannot afford the fee, you can file a Petition to Proceed In Forma Pauperis. It requires a detailed disclosure of your income, employment, assets, debts, and dependents, signed under penalty of law, with a continuing obligation to notify the court if your finances improve.6Pennsylvania Courts. Form 2 – Petition to Proceed In Forma Pauperis The court decides whether to waive the fee entirely or in part.
Serving Your Spouse
Filing alone is not enough. Your spouse must receive formal notice, and service of process is a constitutional requirement. Pennsylvania permits several methods. You can send the complaint by certified mail with return receipt requested, or have it personally delivered by the county sheriff or any adult who is not a party to the case. Some counties also allow a private process server.
Whoever serves the papers must complete and file a proof of service with the prothonotary. That document goes into the case record and confirms the court has jurisdiction over your spouse. Defective or missing service stalls the case; no Pennsylvania court will grant a divorce if the other side was never properly notified.
If your spouse is dodging service or you genuinely cannot find them, you can petition the court for service by publication, typically in a newspaper of general circulation in the county where they were last known to live. The court grants this only after you show good-faith efforts to locate them by other means.
What Happens After You File
After service, your spouse has a window to file a response. The Notice to Defend spells out that ignoring the case can lead to default. The response, typically called an answer, addresses the claims in your complaint, and your spouse may also file a counterclaim asserting their own grounds or requesting different relief.
The waiting periods depend on the path you chose. For mutual consent, the 90-day clock runs from the date of filing. Once it expires and both parties have signed affidavits of consent, either spouse can file a Praecipe to Transmit Record asking the court to enter the decree.7Cornell Law Institute. 231 Pa Code Rule 1920.73 – Notice of Intention to File Praecipe to Transmit Record Before filing that praecipe, you must give your spouse at least 20 days’ written notice of your intent, unless notice is waived in writing.
For a separation-based case under Section 3301(d), the one-year separation must already be complete before the court will act, and the affidavit and counter-affidavit process adds some time on top. If your spouse contests the separation, expect additional weeks or months for a hearing. Fault cases run on whatever timeline the evidence and scheduling allow.
Claims and Protections to Raise Now
Property division is not decided at the start of the case, but decisions you make at filing affect it. Only marital property is divided, and Pennsylvania is an equitable distribution state, meaning fairly rather than equally, with the court weighing factors like the length of the marriage, each spouse’s income and earning potential, contributions to the household, and each spouse’s economic circumstances.8Pennsylvania General Assembly. Pennsylvania Code Title 23 Chapter 35 – Section 3502 The rule that matters for filing is simpler: if you do not raise a property claim before the decree is entered, you can lose it.
Either spouse can also petition for alimony pendente lite, which is temporary support paid while the divorce is pending, and the court can order the other spouse to contribute to attorney’s fees and to keep health insurance in place.9Pennsylvania General Assembly. Pennsylvania Code Title 23 – Chapter 37 A spouse who has been convicted of a personal injury crime against the other spouse generally cannot receive temporary support, unless denying it would cause manifest injustice.
Once the case is open, restrictions apply to both spouses. Neither may conceal or damage marital property, destroy records, or engage in harassment. Most complaints include a list of prohibited conduct that becomes part of the court’s temporary orders, and violations can bring contempt findings and sanctions that hurt your position.
Common Mistakes That Slow the Start
The most costly early mistake is picking the wrong grounds. If you file for mutual consent and your spouse refuses to sign the affidavit after 90 days, you are stuck converting to a separation-based case and waiting out a full year. Pleading both grounds at once, when you can, avoids that trap.
The second is failing to raise all your claims in the initial filing. Pennsylvania courts can and do enter divorce decrees that strip parties of rights they never asserted. If you want alimony, property division, or counsel fees, those claims need to appear in your complaint, or in a timely counterclaim if your spouse files first.
The third is underestimating service. Handing the papers to your spouse across the kitchen table does not count. Informal delivery leaves no valid record and can be challenged later. Use certified mail or a sheriff, get the proof of service filed, and keep the case moving.
