Pennsylvania recognizes common law marriage only if the relationship was established on or before January 1, 2005. The state abolished the practice as of that date, so no couple can create a new common law marriage in Pennsylvania today no matter how long they live together, share finances, or hold themselves out as married. Couples who met the legal requirements before the cutoff remain married, with the same rights and obligations as any other spouses.
The 2005 Cutoff
Pennsylvania was one of the last states to allow common law marriage before the legislature passed Act 144 in late 2004. The statute added a single, blunt rule to the domestic relations code: no common law marriage created after January 1, 2005, is valid. It also preserved every common law marriage lawfully formed on or before that date.1Pennsylvania General Assembly. Pennsylvania Code Title 23 – Section 1103
So the answer depends entirely on timing. If your relationship began before the cutoff and meets the legal test, you may have a recognized marriage. If it started after, cohabitation and shared finances will not create one. Partners who have lived together for decades, raise children together, and file joint tax returns are simply not married under Pennsylvania law if they never obtained a license and their relationship began after 2004. They have no automatic right to inherit from each other, no standing to seek spousal support, and no claim to equitable property division if the relationship ends.
Proving a Pre-2005 Common Law Marriage
A couple claiming a grandfathered common law marriage carries the burden of proving it existed, and Pennsylvania courts apply a demanding standard: clear and convincing evidence. This is a higher bar than the “more likely than not” test used in most civil disputes. Courts want strong proof, not a plausible story.
Words of Present Agreement
The strongest evidence is a mutual exchange of words in the present tense expressing an agreement to be married right then and there. Pennsylvania legal tradition calls this verba de praesenti. Saying “I take you as my husband” at a specific moment satisfies the element. Vague promises to marry someday, plans for a future ceremony, or calling each other “husband” and “wife” in casual conversation do not.
Cohabitation and Reputation
When no one witnessed those spoken words, courts can still recognize the marriage through a rebuttable presumption built on two things: cohabitation and reputation. Cohabitation means the couple lived together as a single household over an extended period. Reputation means people in their community understood them to be married. Useful evidence includes joint tax returns, insurance policies and beneficiary forms listing each other as spouses, use of the same last name, and introductions as husband or wife in social and professional settings.
The word “rebuttable” matters. The presumption shifts the burden, but the other side can challenge it. An estranged family member contesting a will, for example, could present evidence that the couple never actually agreed to be married. Courts weigh the totality of the evidence, and cases where the couple’s behavior was inconsistent are harder to win.
What Happens If You Cannot Prove It
Failing to meet the standard means the court treats you as though you were never married. No right to a share of your partner’s estate if they die without a will. No standing to seek alimony or equitable property division. No eligibility for survivor benefits through Social Security. These disputes usually surface after one partner dies or the couple separates, and the stakes are high.
Rights of a Recognized Common Law Spouse
Once proven, a common law marriage carries the same legal weight as a marriage performed with a license and officiant. Pennsylvania draws no distinction between the two. A recognized common law spouse can inherit under intestate succession laws if their partner dies without a will, seek equitable distribution of marital property in a divorce, and receive spousal support and alimony.
The marriage also triggers the presumption of paternity for any children born during the relationship. When the marriage is intact, that presumption is essentially irrebuttable, and it carries through to custody, child support, and inheritance rights.
Federal Benefits
Federal agencies follow a straightforward rule: if a state recognizes the marriage, the federal government does too. The IRS treats a couple as married for the entire tax year if they have a valid common law marriage recognized by the state where the marriage began, even if they later move to a state that does not allow common law marriage.2Internal Revenue Service. Publication 501, Dependents, Standard Deduction, and Filing Information A Pennsylvania couple with a valid pre-2005 common law marriage can file joint federal returns, claim spousal deductions, and access every tax benefit available to formally married couples.
Social Security survivor benefits follow the same principle but require documentation. The Social Security Administration asks the surviving spouse to complete Form SSA-754, a detailed statement about the marital relationship. The agency also collects statements on Form SSA-753 from blood relatives of the deceased spouse and, in some cases, from relatives of the surviving spouse. When these forms are consistent and the agency has no contradictory information, it generally accepts the marriage as valid without requiring additional evidence.3Social Security Administration. Program Operations Manual System – Pennsylvania Gathering supporting documents while both partners are alive makes the process far easier for the survivor later.
You Still Need a Divorce to End It
A valid common law marriage does not end just because the couple stops living together. Pennsylvania treats it identically to a ceremonial marriage, which means a formal court divorce is required to dissolve it. Moving out, separating finances, or starting a new relationship does not change your marital status.
The same divorce options apply as for any married couple. The most common path is a mutual consent divorce, where both parties file affidavits agreeing to end the marriage at least 90 days after the divorce complaint is served. If one partner refuses to consent, the other can pursue a no-fault divorce after the parties have been separated for at least one year. Fault-based divorce remains available for adultery, abandonment, or similar grounds, though it requires a hearing.
Property division follows Pennsylvania’s equitable distribution rules. A court divides marital assets based on factors including the length of the marriage, each partner’s income and earning capacity, contributions as a homemaker, and each party’s health and needs.4Pennsylvania General Assembly. Pennsylvania Code Title 23 – Section 3502 “Equitable” does not automatically mean a 50-50 split. The court has broad discretion to assign different percentages to different assets. Any property held as tenants by the entireties converts to a tenancy in common with equal shares once the divorce is final.5Pennsylvania General Assembly. Pennsylvania Code Title 23 – Chapter 35, Property Rights
Skipping the divorce creates problems that compound. You remain legally married, so you cannot validly marry someone else. Your estranged common law spouse retains inheritance rights if you die without a will. And assets accumulated during a long separation may still be subject to equitable distribution when someone finally files.
Common Law Marriages From Other States
A handful of states still allow couples to create new common law marriages, including Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and the District of Columbia. If you formed a valid common law marriage in one of those jurisdictions, Pennsylvania recognizes it. The general rule across nearly all states is that a marriage valid where it was created is valid everywhere, and Pennsylvania follows this principle. Your marriage does not lose its legal status when you cross state lines.
The catch is that the marriage must actually have been valid under the laws of the state where it was formed. Moving to Pennsylvania does not cure a defective common law marriage. If the originating state required cohabitation and you never lived together there, the marriage may not have been valid to begin with. Pennsylvania will not fill that gap.
If You Don’t Have a Common Law Marriage
For couples who assumed they had a common law marriage and now realize they don’t, the fix is a marriage license. Pennsylvania law is explicit that no one can be joined in marriage without one.6Pennsylvania General Assembly. Pennsylvania Code Title 23 – Section 13017Lehigh County Court of Common Pleas.
