Do you have to be separated, or live in Pennsylvania six months, before a divorce?

To file for divorce in Pennsylvania, at least one spouse must have been a bona fide resident of the state for at least six months immediately before filing. You do not need to be separated for any set time to get a mutual consent divorce. A one-year period of living separate and apart matters only if you use the other no-fault ground, usually because one spouse will not consent.

These eligibility rules apply to every divorce, collaborative or not. Knowing them early helps you decide when to file and which ground to use. For how the collaborative process fits around them, see our collaborative family law page and how a collaborative divorce works, step by step.

How the eligibility rules work, step by step

1. Check residency. Under 23 Pa.C.S. § 3104(b), at least one spouse must have been a bona fide Pennsylvania resident for at least six months immediately before the action begins. Both spouses can testify about where they have lived, and six months of actual residence creates a presumption of domicile in Pennsylvania.
2. Choose the ground. Most collaborative couples use mutual consent (§ 3301(c)). If one spouse will not consent, the separation ground (§ 3301(d)) may apply. Fault grounds exist in § 3301(a) but are rarely used in collaborative cases.
3. For mutual consent: no separation period is required. The marriage must be irretrievably broken, 90 days must pass after the complaint is served, and each spouse files an affidavit of consent.
4. For the separation ground: you must have lived separate and apart for at least one year, and one spouse files an affidavit saying so and that the marriage is irretrievably broken.
5. Record your separation date. Even when it does not decide the ground, the date of final separation affects which property is marital.

The one-year rule, and when the old two-year rule still matters

Pennsylvania shortened the separation period for the § 3301(d) ground from two years to one year in 2016 (Act 102 of 2016). The amendment applies to periods of living separate and apart that began after it took effect, so for almost every couple separating today the period is one year. If your separation began before that change, ask your lawyer how the rule applies to you.

If one spouse denies the allegations in a § 3301(d) affidavit, the court holds a hearing. If it finds a reasonable prospect of reconciliation, it must continue the matter for 90 to 120 days (longer if both agree) and require counseling if requested. Collaborative couples rarely face this, because they usually agree to use mutual consent.

Why the separation date matters even in a mutual consent divorce

Your separation date does more than set a clock. Under 23 Pa.C.S. § 3501(a)(4), property acquired after final separation until the divorce is generally not marital property, unless it was acquired in exchange for marital assets. In a court case, each spouse's inventory lists property owned as of the date of separation (§ 3505(b)). Spousal support and alimony pendente lite are also tied to the period after separation.

For these reasons, the collaborative process usually starts by agreeing on the separation date. If you disagree about it, that disagreement becomes one of the issues to negotiate. See dividing property in a collaborative divorce and how spousal support and alimony are settled by agreement.

Residency questions that come up often

• One spouse moved out of state. Only one spouse needs to meet the six-month residency rule.
• You recently moved to Pennsylvania. You may need to wait until six months have passed before filing here, or consider filing where you lived before. Collaborative negotiation can begin before you file.
• Military or temporary absences. "Bona fide resident" refers to genuine residence; temporary absences do not necessarily break it. Discuss specific facts with a lawyer.
• Children and custody. Custody cases follow their own rules about where to file. The Allegheny County Family Division explains that custody venue generally rests where the children have lived for the past six months.

Choosing where to file: county questions

Residency answers whether Pennsylvania can hear the divorce; the next question is which county. Families often have a natural choice: the county where they live or where they lived together. For Pittsburgh-area families that is usually Allegheny County, where the Family Division handles divorce, custody and support at the Family Law Center; see our Pittsburgh and Allegheny County page. Around Ellwood City, the choice can be less obvious, because the borough sits partly in Lawrence County and partly in Beaver County. Our Ellwood City and Lawrence County page explains the Lawrence County offices. Your lawyer will confirm the right county for your facts.

Separating well: practical steps that protect both spouses

The period right after a separation shapes much of what follows. A few practical habits make the legal work easier, whichever divorce ground you end up using.

• Write the date down and tell your spouse in writing. A short, calm message noting that you consider yourselves separated as of a specific date avoids later disputes about when the marriage ended in practice.
• Keep a snapshot of the finances. Download statements for every account as of the separation date. Values on that date are often the starting point for dividing property.
• Agree on temporary bills. Who pays the mortgage, utilities and insurance while you work things out? A short written arrangement prevents missed payments that hurt both credit records.
• Keep the children's routine steady. A temporary schedule both parents follow reduces stress and becomes a useful test for the long-term parenting plan.
• Avoid big financial moves. New debts, large purchases or moving money between accounts can complicate the property picture and damage trust.

None of these steps commits you to a particular outcome. They simply keep options open and make it easier to settle by agreement.

What changes the answer

• Whether both spouses consent. Mutual consent avoids any separation waiting period beyond the 90 days.
• When the separation began. It controls the § 3301(d) clock and affects the property list.
• Living under one roof. Some spouses separate while still sharing a home for practical reasons. Whether that counts as "separate and apart" depends on the facts; ask before relying on it.
• Abuse. Consent is presumed for a spouse convicted of a personal injury crime against the other (§ 3301(c)(2)), and counseling cannot be required over the objection of a spouse with a protection from abuse order (§ 3302(g)).
• Timing overall. See how long a collaborative divorce takes.

A worked example

Common mistakes

• Assuming you must be separated a year. Not for mutual consent.
• Filing too soon after moving here. The six-month residency rule applies before filing.
• Leaving the separation date vague. It affects property and support; agree on it early.
• Relying on the old two-year rule. For separations after the 2016 change, the period is one year.
• Confusing divorce residency with custody venue. Custody has its own rules about where to file.

What to do this week

1. Write down where each spouse has lived for the past twelve months.
2. Write down the date you believe you separated and why.
3. Ask whether your spouse would sign an affidavit of consent.
4. Gather documents showing residence, such as a lease, utility bills or a driver's license.
5. Bring all of this to your consultation; see what to bring to a first consultation.
6. Read how the divorce is finalized to see how these rules play out at the end.

Frequently asked questions

Do both spouses have to live in Pennsylvania?

No. Only one spouse must have been a bona fide resident for six months immediately before filing.

Is there a waiting period for a mutual consent divorce?

Yes: affidavits of consent can be signed only once 90 days have passed after the complaint was served.

Can we be separated while living in the same house?

It depends on the facts. Discuss it with your lawyer before relying on it for the one-year ground.

What if my spouse will not consent?

You may use the § 3301(d) ground after one year of living separate and apart, or a fault ground in some cases.

Does the separation date matter if we both consent?

Yes. It affects which property is marital and how it is valued.

Do I need to prove residency?

Both spouses can testify to residence, and six months of actual residence creates a presumption of domicile in Pennsylvania.
