No amount of time living together will make you legally married. The idea that you have to live together for seven years, or any other set number of years, to be married is a myth with no basis in any state’s law. What some states do recognize is a common law marriage, and that status depends on whether you and your partner meet specific legal requirements, not on how long you have shared an address. A couple could live together for 30 years and never be married in the eyes of the law. Another couple could be legally married in far less time if every element is in place.
Why the Seven-Year Rule Is a Myth
No state has ever passed a law that turns cohabitation into marriage after a set period. Family law scholars have looked for the origin of the seven-year rule for decades and found nothing legislative behind it. Duration is not the deciding factor anywhere in the United States.
The confusion likely comes from the fact that living together is one ingredient of common law marriage in the states that still recognize it. But it is only one ingredient, and time alone creates nothing. What courts actually look for is whether both people intended to be married and behaved publicly like spouses. Time can support that showing, but on its own it does not.
What Actually Creates a Common Law Marriage
In states that recognize it, courts look for three things happening together. Miss any one and no marriage exists, no matter how many years have passed.
A present agreement to be married. Both partners must mutually agree that they are married right now. A plan to marry someday, or an engagement, does not qualify. The agreement can be spoken or shown through conduct, but it has to reflect a current shared understanding that the relationship is a marriage.
Public representation as spouses. The couple must consistently present themselves to others as married. That means introducing each other as husband or wife, sharing a last name, filing joint federal tax returns, listing each other as a spouse on insurance forms and loan applications, and naming each other as spouses on estate documents. Telling a few friends is not enough. The couple has to have a general reputation as a married pair.
Cohabitation. The couple must live together in a way that looks like a marital household, not a casual or temporary setup. No state sets a minimum duration.
Courts increasingly weigh the full picture rather than checking each box in isolation: shared finances, joint estate planning, rings and anniversary celebrations, how the couple referred to each other, and how they behaved when the relationship ended. Someone who first claims a common law marriage years after a breakup tends to face far more skepticism than someone who asserted it while the relationship was ongoing.
Legal Capacity Comes First
Before any of the three elements matter, both partners must have the legal capacity to marry. Both must be at least 18, mentally competent to consent, and not currently married to anyone else. If one partner is still legally married to a former spouse, no common law marriage can form until that prior marriage ends through divorce or death. This is where many claims quietly fall apart, especially when someone assumed a prior divorce was final but never actually obtained the decree.
Where Common Law Marriage Still Exists
Only a small number of jurisdictions allow couples to form a new common law marriage today:
- Colorado
- District of Columbia
- Iowa
- Kansas
- Montana
- Oklahoma (through case law, not statute)
- Rhode Island (through case law, not statute)
- Texas
Two states handle unmarried couples in a distinct way. Utah allows a court or administrative body to recognize an unsolemnized relationship as a valid marriage, but only if a petition is filed while the relationship is still ongoing or within one year after it ends.1Utah Legislature. Utah Code 30-1-4.5 – Validity of Marriage Not Solemnized New Hampshire uses a narrower rule: couples who cohabit and acknowledge each other as spouses for at least three years are deemed legally married only after one of them dies, which makes the rule relevant for inheritance but not during the couple’s lifetime.2New Hampshire General Court. New Hampshire Revised Statutes 457:39 – Cohabitation, Etc.
If you live anywhere else, you cannot create a common law marriage there no matter how long you cohabit or how publicly you hold yourselves out as spouses.
States That Grandfathered Older Common Law Marriages
Several states used to allow common law marriage and have since abolished it. Couples who established their marriage before the cutoff remain legally married. Anyone who began cohabiting or holding out as spouses after the cutoff has no claim.
- Alabama: before January 1, 20173Alabama Legislature. Alabama Code 30-1-20 – Common-Law Marriage Abolished
- Florida: before January 1, 1968
- Georgia: before January 1, 1997
- Idaho: before January 1, 1996
- Indiana: before January 1, 1958
- Ohio: before October 1991
- Pennsylvania: before January 1, 2005
- South Carolina: before July 24, 2019
Some of these cutoffs are now largely historical. An Indiana common law marriage would require both partners to have been adults in 1957. Alabama’s 2017 cutoff and South Carolina’s 2019 change are recent enough that disputes about pre-existing common law marriages there are still active.
What Happens When You Move
A common law marriage that was validly formed in a recognizing state is treated as a legal marriage everywhere in the country. If you and your partner became common law spouses in Iowa and then moved to a state that does not allow common law marriages, you are still legally married in your new state. Interstate recognition of marriages is a long-established rule.
The reverse is not true. You cannot pick up common law marriage status by visiting a recognizing state on vacation. Cohabitation and community reputation as a married couple cannot be built during a weekend trip. Your shared life has to actually be based in a state that recognizes the status.
You Cannot End a Common Law Marriage by Walking Away
Once a common law marriage is validly established, it carries every obligation of a ceremonial marriage. That includes the requirement to formally dissolve it through a court divorce. Moving apart, dropping a shared name, or deciding the relationship is over does not end it.
Skipping the divorce creates serious problems. Any later marriage would be legally void because you were still married. If you die without a will, your common law spouse may have a claim to your estate. Property acquired during the marriage may be subject to marital division rules. The only clean exit is the same divorce process any other married couple has to use, including division of assets, potential spousal support, and court orders regarding any children.
Protection When You Don’t Qualify
If you live in a state that doesn’t recognize common law marriage, or you haven’t met the requirements, the law treats unmarried partners as legal strangers. If the home is in one partner’s name, it belongs to that partner alone when the relationship ends. If one partner dies without a will, intestacy laws distribute assets to legal spouses, children, and blood relatives, and the surviving partner inherits nothing. There is no right to spousal support, no automatic claim to shared property, and no automatic standing to make medical decisions for an incapacitated partner.
A few states allow palimony claims, where one partner seeks financial support based on an agreement made during the relationship. Most states do not, and where they exist, these claims are difficult to prove and far less protective than marital rights.
The most reliable protection for unmarried couples is a written cohabitation agreement. Most states enforce these contracts. A cohabitation agreement can address how property and debts will be divided if the relationship ends, whether either partner owes financial support, what happens to a shared home, and who makes healthcare decisions if a partner becomes incapacitated. It will not give you marital tax benefits or automatic inheritance rights, but it replaces the legal vacuum with an enforceable plan. Drafting one professionally typically costs between $500 and $800.
Couples who want inheritance protection should also execute wills naming each other as beneficiaries, designate each other on retirement accounts and life insurance, and consider holding jointly owned property with rights of survivorship. None of these steps require marriage, but all of them require deliberate action. Without them, decades of shared life count for nothing in the eyes of the law.
