Pennsylvania is not a common law marriage state for any couple whose relationship began on or after January 1, 2005. The legislature abolished the doctrine as of that date, so a couple who wants to be legally married in Pennsylvania today has to get a license and have a ceremony. Common law marriages that were validly formed before January 1, 2005, remain fully legal, but proving one exists requires meeting a demanding evidentiary standard.
The January 1, 2005 Cutoff
Under 23 Pa.C.S. ยง 1103, no common law marriage “contracted after January 1, 2005, shall be valid.”1Pennsylvania General Assembly. 23 Pennsylvania Consolidated Statutes 1103 – Common-Law Marriage The same statute protects older unions, saying nothing in the law renders a common law marriage “otherwise lawful and contracted on or before January 1, 2005, invalid.”2Pennsylvania General Assembly. Title 23 Domestic Relations – Section 1103
The rule is bright-line. A union established before 2005 carries the same legal weight as a licensed marriage. One that wasn’t will never become one, no matter how long the couple lives together, shares finances, or presents themselves to the world as married.
What a Valid Pre-2005 Common Law Marriage Required
Length of cohabitation alone was never enough. Pennsylvania courts required something lawyers call verba in praesenti: words spoken in the present tense. Both people had to say something to each other, at a specific moment, that expressed an immediate agreement to be married then and there. Think of it as a private vow. Without that exchange of words, the union does not qualify.
The Pennsylvania Supreme Court reinforced this in Staudenmayer v. Staudenmayer, holding that when both parties are alive and available to testify, the person claiming the marriage must produce “clear and convincing evidence” of the exchange.3Administrative Office of Pennsylvania Courts. PNC Bank Corp. v. Workers’ Compensation Appeal Board That is a higher bar than the “more likely than not” standard used in most civil disputes.
Both partners also needed the legal capacity to marry at the moment of the exchange. Each had to be at least 18, of sound mind, and not already married to someone else.4Pennsylvania General Assembly. Title 23 Domestic Relations – Section 1304 If either person was still legally bound to a prior spouse at the time, the common law marriage is void from the start.
Proving One Exists Today
Because these marriages are informal by nature, proving one usually means assembling a mosaic of documents and testimony showing both the verbal agreement and a consistent pattern of living as a married couple. The strongest evidence tends to be records where both partners represented themselves as married to third parties.
- Joint federal and state tax returns filed as “married filing jointly,” because misrepresenting marital status to taxing authorities carries real consequences.
- Deeds and mortgages listing both partners as spouses.
- Life insurance policies, employer health plans, and retirement accounts naming the partner as a spouse.
- Testimony from friends, family, neighbors, and coworkers who consistently understood the couple to be married.
Courts weigh the totality of the evidence. A single document rarely carries the day, but a consistent pattern of shared finances, joint accounts, and public recognition reaching back before 2005 builds a credible case. Everything that establishes the marriage itself must predate January 1, 2005. Later conduct can support an existing marriage, but it cannot create a new one.
Marriages Formed in Other States
If you formed a valid common law marriage in a state that still permits them and then moved to Pennsylvania, the marriage does not evaporate at the state line. Under the Full Faith and Credit Clause, Pennsylvania generally recognizes marriages that were validly created under the laws of another state. A couple who met Colorado’s or Texas’s requirements, for example, can expect Pennsylvania to treat them as legally married.
The marriage must actually have been valid where it was created. Spending a few months in another state without meeting its requirements does not produce a marriage Pennsylvania will later recognize. The law of the state where the union was formed controls whether it was properly established.
Ending a Common Law Marriage
There is no such thing as a common law divorce. A valid common law marriage ends only through death, divorce, or annulment. Living apart, even for years, does not dissolve it. If you have a recognized pre-2005 common law marriage and want to end it, you file a divorce complaint and go through equitable distribution of marital property under the Divorce Code, the same as any other married couple.
Skipping that step causes real problems. If you separate from a common law spouse without divorcing and then try to marry someone else, you are still legally married to the first partner. A new marriage license would be invalid, and the financial and property entanglements from the earlier marriage remain live.
Social Security and Federal Benefits
A valid pre-2005 Pennsylvania common law marriage qualifies you for the same federal benefits as any licensed marriage, including Social Security spousal and survivor benefits. The Social Security Administration runs its own verification process separate from any state court proceeding.
The SSA’s preferred evidence is signed statements from both spouses, or from the surviving spouse if one has died, together with statements from two blood relatives explaining why they believe the marriage existed.5Social Security Administration. 20 CFR 404.726 – Evidence of Common-Law Marriage If a blood relative isn’t available, a statement from someone else who knows the couple can substitute. Where the preferred evidence doesn’t exist, the SSA will consider other convincing documentation, but you have to explain why the standard proof isn’t available.
Federal employees adding a common law spouse to a Federal Employees Health Benefits plan need either a court order recognizing the marriage or a signed declaration, backed by supporting documents such as the first page of a joint tax return or proof of shared residency and combined finances.6U.S. Office of Personnel Management.

If You Can’t Form One, Build Protections Instead
Because new common law marriages have been off the table in Pennsylvania for more than two decades, unmarried couples who want legal protections have to create them deliberately. Without those steps, the law treats you and your partner as legal strangers, and the gap shows up most painfully around property, healthcare, and inheritance.
Cohabitation Agreements
A cohabitation agreement is a written contract between unmarried partners covering how property, finances, and debts are handled during the relationship and if it ends. These agreements are enforced under general contract law, not the Divorce Code, so Pennsylvania’s equitable distribution rules do not apply. Without an agreement, property generally belongs to whoever holds title, regardless of who paid for it. A well-drafted agreement can address ownership of real estate and vehicles, responsibility for shared debts, and whether either partner will provide support if the relationship ends.

Inheritance Consequences
The financial gap between married and unmarried couples is widest at death. A surviving spouse in Pennsylvania pays zero inheritance tax on assets received from a deceased partner. An unmarried partner pays 15 percent.8Pennsylvania Department of Revenue. Inheritance Tax On a $500,000 estate, that is $75,000 a married couple would never owe.
It gets worse without a will. Pennsylvania’s intestacy statute distributes assets only to a surviving spouse and blood relatives.9Pennsylvania General Assembly. Title 20 Decedents, Estates and Fiduciaries – Section 2102 An unmarried partner receives nothing, no matter how long you lived together. Everything passes to children, parents, siblings, or more distant relatives. If no family survives, the estate goes to the state before it goes to you. At a minimum, each partner should have a will naming the other as a beneficiary, durable powers of attorney for finances and healthcare, and beneficiary designations on retirement accounts and life insurance that reflect your wishes.
Getting a Marriage License
The cleanest route to full legal protection is a marriage license. In Philadelphia, the fee is $90 for a regular license or $100 for a self-uniting (Quaker) license.10City of Philadelphia. Get a Marriage License Fees vary slightly by county. A licensed marriage immediately provides inheritance tax exemption, intestacy rights, healthcare decision-making authority, and access to spousal benefits through employers, Social Security, and other federal programs.
