Every divorce in Pennsylvania has to be filed on a recognized legal ground. Some couples agree the marriage is over and file on no-fault grounds, while others ask the court to grant a divorce because of specific misconduct by their spouse. The ground you choose affects how long the case takes, what you have to prove, and how it can interact with issues like alimony and property division.

Most divorces filed in Pennsylvania today are no-fault. Under 23 Pa.C.S. § 3301(c) and § 3301(d), a spouse can ask the court to end the marriage without proving wrongdoing. There are two main no-fault paths, plus a narrower no-fault ground for cases involving institutionalization.
If both spouses agree the marriage is irretrievably broken, Pennsylvania allows a mutual-consent divorce after a 90-day waiting period from the date the divorce complaint is served. Both parties file affidavits consenting to the divorce, and the court can move the case forward without litigating fault. This is typically the fastest, lowest-cost path, and it pairs well with an uncontested divorce when there are no major disputes over property, custody, or support.
If one spouse will not consent, the other can still pursue a no-fault divorce by showing the marriage is irretrievably broken and that the parties have lived separate and apart for at least one year. Separation does not always require living in different homes, but it does require an end to the marital relationship. This route is common when one spouse refuses to sign consent paperwork or has gone silent.
Pennsylvania also recognizes a no-fault ground when one spouse has been confined to a mental institution for at least 18 months before the divorce filing and is unlikely to be released within the next 18 months. This is rarely used but remains on the books under the no-fault framework.
Fault grounds are still available in Pennsylvania under 23 Pa.C.S. § 3301(a), but they are used less often because they require proof of misconduct and can extend the timeline. They may make sense when one spouse’s behavior is relevant to claims for alimony or when establishing fault carries personal or strategic value. Pennsylvania law lists six fault grounds plus a separate fault ground for insanity.
A spouse can seek a fault divorce on the ground that the other spouse committed adultery. Evidence usually goes beyond suspicion and involves documents, communications, or witness testimony. Adultery can also surface in alimony discussions, since marital misconduct is one of the factors PA courts weigh in awarding spousal support after the divorce.
Willful and malicious desertion for a continuous period of one year or longer is a fault ground in PA. The spouse left behind must show the departure was without reasonable cause and without consent. Simply moving out during a separation does not by itself meet this standard.
If a spouse has endangered the other’s life or health through cruel or barbarous treatment, that is a recognized fault ground. This category covers serious physical abuse and conduct that puts the filing spouse at risk. Domestic violence allegations may also support a Protection From Abuse (PFA) petition through Allegheny County Family Division alongside the divorce filing.
Indignities is a catch-all fault ground used when one spouse has engaged in a sustained course of conduct that makes the other spouse’s life intolerable and burdensome. Courts look at behavior over time rather than a single incident, and the conduct must be serious enough to render the marriage unworkable.
If a spouse knowingly entered a second marriage while a prior marriage was still legally valid, the other spouse can file on the ground of bigamy. The earlier undissolved marriage typically also makes the second marriage void or voidable, which is why bigamy cases sometimes overlap with annulment questions.
Conviction of a crime followed by a sentence of two or more years in prison is a fault ground for divorce. The conviction itself does not automatically end the marriage. The spouse seeking the divorce still has to file and prove the ground.
A spouse who has been confined in a mental institution for at least 18 months at the time of filing, with little prospect of release within the next 18 months, may be the subject of a fault-based insanity divorce in PA. This ground overlaps with the no-fault institutionalization category, and the choice often comes down to which framework better fits the rest of the case.
For most clients, a no-fault divorce is faster and less expensive. Fault grounds bring evidence, witnesses, and contested hearings into the picture, which extends the timeline and increases legal fees. Fault can still be the right call when the misconduct is relevant to a claim for alimony, when there is a strategic reason to establish wrongdoing on the record, or when one spouse refuses to engage with a no-fault filing in good faith.
It is common to file a no-fault count and a fault count in the same complaint and let the case develop. As discovery proceeds and the divorce court process unfolds, many cases that started with fault claims settle as a no-fault divorce with negotiated terms on property and support. A Pittsburgh family law attorney can help you decide which grounds to plead given your goals and the facts of your marriage.
Mutual consent no-fault divorces can be finalized in roughly 90 days after the complaint is served, once both parties file consent affidavits and any property, support, and custody issues are resolved. No-fault divorces based on irretrievable breakdown without consent require a one-year separation period, so the timeline is at least a year from the date of separation plus the time needed to litigate any contested issues.
No. Pennsylvania allows no-fault divorce on the grounds of mutual consent or irretrievable breakdown after a one-year separation. You do not have to prove your spouse did anything wrong to obtain a divorce in PA. Fault grounds remain available for spouses who want to use them, but they are optional, not required.
Your spouse can refuse to sign consent, which blocks the 90-day mutual consent path. However, your spouse cannot prevent the divorce indefinitely. After a one-year separation, you can pursue a no-fault divorce on the ground of irretrievable breakdown without your spouse’s consent.
Fault does not change how marital property is divided under Pennsylvania’s equitable distribution law, but marital misconduct is one of the factors PA courts consider when deciding whether to award alimony and in what amount. Adultery and certain other fault grounds can be relevant to that analysis.
You can still file for divorce in Pennsylvania if your spouse cannot be located. The court has procedures for service by publication after you have made a diligent effort to find your spouse. These cases tend to follow the no-fault irretrievable-breakdown path because the one-year separation requirement is usually satisfied by the spouse’s absence.
Choosing the right grounds is one of the first decisions you will make in your divorce, and it shapes nearly every step that follows. Pittsburgh divorce attorney Anthony Piccirilli helps clients across Allegheny County weigh fault and no-fault options, gather the right evidence, and coordinate the grounds with related issues like custody, child support, and property division.
