Pennsylvania recognizes four ways to legally end or undo a marriage: no-fault divorce by mutual consent, no-fault divorce after a one-year separation, fault-based divorce, and annulment. The three types of divorce in Pennsylvania all end a valid marriage; annulment declares that the marriage was never valid to begin with. Which one fits depends on whether your spouse will cooperate, how quickly you want it resolved, and whether proving misconduct is worth the fight. Before any of them are available, at least one spouse must have lived in Pennsylvania for six months immediately before filing.1Pennsylvania General Assembly. Pennsylvania Code 23-3104 – Bases of Jurisdiction
No-Fault Divorce by Mutual Consent
This is the fastest and cheapest route, and it’s the one most couples take. Both spouses agree the marriage is irretrievably broken, and neither has to prove the other did anything wrong.
One spouse files a divorce complaint. The law then imposes a 90-day waiting period before either party can file an affidavit of consent.2Pennsylvania General Assembly. Pennsylvania Code 23-3301 – Grounds for Divorce After the 90 days, both spouses sign and file affidavits confirming consent, and the court can finalize the divorce once property division, support, and any custody matters are resolved or set aside for separate determination.
There’s one shortcut around the consent requirement. If one spouse has been convicted of a personal injury crime against the other, consent is automatically presumed, so the abused spouse doesn’t need the other’s signature to proceed under this section.2Pennsylvania General Assembly. Pennsylvania Code 23-3301 – Grounds for Divorce
No-Fault Divorce After a One-Year Separation
When you want out but your spouse won’t cooperate, this is the workaround. If you’ve lived separate and apart for at least one year, you can file a divorce complaint alleging the marriage is irretrievably broken, then file an affidavit confirming the separation period and the breakdown.2Pennsylvania General Assembly. Pennsylvania Code 23-3301 – Grounds for Divorce
If your spouse doesn’t contest the affidavit, the divorce moves forward. If your spouse denies the separation or the breakdown, a judge holds a hearing and will still grant the divorce if the evidence shows you’ve genuinely been living apart for a year and the marriage can’t be saved.2Pennsylvania General Assembly. Pennsylvania Code 23-3301 – Grounds for Divorce If the judge sees a realistic chance of reconciliation, the case is continued for 90 to 120 days with mandatory counseling before a final decision.
What Separate and Apart Actually Means
You don’t have to move out. Pennsylvania recognizes that couples can live “separate and apart” under the same roof. What matters is that you’ve stopped functioning as a married couple: separate bedrooms, eating apart, no longer socializing together, and no sexual relationship. Filing the divorce complaint itself creates a legal presumption that the separation began no later than the date your spouse was served.
For couples who can’t afford two households on top of a divorce, this is a practical reality. Courts see it often and it won’t automatically hurt your case, but you need to be able to show the separation was genuine if your spouse disputes it.
Fault-Based Divorce
Fault-based divorce requires the “innocent and injured” spouse to prove that the other spouse’s misconduct destroyed the marriage. Pennsylvania recognizes six grounds:2Pennsylvania General Assembly. Pennsylvania Code 23-3301 – Grounds for Divorce
- Desertion, meaning your spouse left the marital home without reasonable cause and stayed away for one year or more.
- Adultery.
- Cruel treatment that endangered your life or health.
- Bigamy, meaning your spouse married you while still legally married to someone else.
- A criminal conviction resulting in a sentence of two or more years in prison.
- Indignities, meaning a pattern of behavior that made your living conditions intolerable.
Proving fault means presenting evidence to a judge, which makes this path slower, more contentious, and significantly more expensive than either no-fault option. So why choose it?
Fault Affects Alimony, Not Property
This is the part that surprises most people. Fault has no effect on how the court divides property. Pennsylvania’s equitable distribution statute explicitly says marital property is divided “without regard to marital misconduct.”3Pennsylvania General Assembly. Pennsylvania Code 23-3502 – Equitable Division of Marital Property It doesn’t matter how badly your spouse behaved; the judge splits assets based on factors like marriage length, income and earning capacity, and contributions to the household.
Alimony is different. Marital misconduct during the marriage is one of 17 factors a court weighs when deciding whether to award alimony, how much, and for how long.4Pennsylvania General Assembly. Pennsylvania Code 23-3701 – Alimony Misconduct after the date of final separation doesn’t count, with one exception: abuse by one spouse against the other is always relevant regardless of timing. So a fault-based divorce can influence alimony, but it’s one factor among many, not an automatic win.
Annulment
Annulment is legally distinct from divorce. Divorce ends a valid marriage; annulment declares that the marriage was never legally valid. Either party can file an annulment action in Pennsylvania if the marriage was void or voidable under state law.5Pennsylvania General Assembly. Pennsylvania Code 23-3303 – Annulment of Void and Voidable Marriages
Void marriages are those that were never legally permitted, such as bigamous marriages or marriages between close relatives. Voidable marriages involve circumstances like fraud, duress, or one party being underage or mentally incapacitated at the time of the ceremony. The same six-month residency requirement that applies to divorce also applies to annulment.1Pennsylvania General Assembly. Pennsylvania Code 23-3104 – Bases of Jurisdiction
Annulments are uncommon because few marriages meet these narrow criteria. If you’re considering one, the grounds need to be clear-cut. Courts can still address property division and support in an annulment proceeding, so annulment doesn’t necessarily mean walking away with no financial obligations.
Choosing Among the Options
Start with cooperation. If your spouse will sign an affidavit of consent, mutual consent is almost always the right path: it’s the cheapest, quickest, and least combative. The 90-day waiting period is the main constraint.
If your spouse won’t cooperate, the one-year separation route gets you divorced without needing their signature and without having to prove wrongdoing. The tradeoff is time. You need a full year of separation before you can file the affidavit that moves the case forward.
Fault-based divorce is worth considering only when misconduct is likely to affect an alimony award you actually need, and when you have the evidence to prove it. The expense and conflict of a fault case make it a poor default. It buys you nothing on property division.
Annulment is a narrow tool for marriages that were legally defective from the start. If the grounds don’t clearly fit, one of the divorce paths is the answer.
