No length of time creates a common law marriage in Florida. Whether you have lived together for five years, twenty, or forty, cohabitation alone will never make you legally married in this state. Florida abolished common law marriage effective January 1, 1968, and Florida Statute 741.211 makes the rule absolute: no common law marriage entered into after that date is valid.1Florida Senate. Florida Code Title XLIII Chapter 741 – Section 741.211 If you want the legal status of a spouse in Florida, you need a marriage license and a ceremony. Time by itself does nothing.
Why the “How Many Years” Question Has No Answer Here
The idea that seven years, or ten, or any specific stretch of cohabitation converts a relationship into a marriage is a widespread myth. It was never quite true even in states that do permit common law marriage. Those states look for mutual intent to be married and holding yourselves out publicly as spouses, not a stopwatch. In Florida the question is moot in a stronger way: the option does not exist at all. There is no year count that unlocks it, because the door has been closed since 1968.
Florida law creates no legal rights or duties between unmarried partners who live together, regardless of how long or how marriage-like the arrangement looks from the outside.2The Florida Bar. Codifying Cohabitation as a Ground for Modification or Termination of Alimony Sharing a mortgage, raising children together, filing beneficiary paperwork, calling each other husband and wife in front of neighbors — none of it adds up to a marriage under Florida law.
The Narrow Exceptions People Mistake for a Loophole
A few situations get read as backdoors to common law marriage. They are not.
Defective Ceremonial Marriages Entered in Good Faith
Section 741.211 preserves marriages that were “otherwise defective” but entered into in good faith and in substantial compliance with Florida’s marriage laws.1Florida Senate. Florida Code Title XLIII Chapter 741 – Section 741.211 This protects couples who actually obtained a license and went through a ceremony, only to discover later that something was technically wrong — a paperwork error, an officiant whose authority was flawed. It does not help couples who never got a license.
The related putative spouse doctrine works the same way. A putative spouse is someone who genuinely believed they were legally married, usually because of a hidden impediment like an undissolved prior marriage on the other side. Florida courts have allowed putative spouses to claim certain property rights and temporary support, but only when there was an attempted formal marriage in the first place. Living together and referring to each other as spouses does not qualify.
Common Law Marriages Formed in Florida Before 1968
Any common law marriage validly formed in Florida before January 1, 1968, is still recognized. Those marriages required mutual consent to be married and legal capacity to marry, with cohabitation and public acknowledgment serving as evidence of that consent. No fixed duration was ever required. These marriages are now close to sixty years old, so they surface almost exclusively in estate disputes, where proof usually depends on old joint tax returns, deeds, insurance policies, and testimony from people who knew the couple at the time.
Common Law Marriages Formed in Another State
Florida will recognize a common law marriage that was validly formed in a state where such marriages are legal, under the Full Faith and Credit Clause. The word doing the work is “validly.” You must have actually met the other state’s requirements while living there. A weekend visit to a state that allows common law marriage does not create one, and Florida-based facts cannot be used to satisfy another state’s rules.
The jurisdictions currently allowing new common law marriages are Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and the District of Columbia.3National Conference of State Legislatures.

What Long-Term Cohabitation Actually Costs You
The reason the “how many years” question matters is usually the fear behind it: that after decades together, one partner will end up with nothing. In Florida, that fear is well founded.
Florida’s intestate succession statute distributes a deceased person’s estate to a surviving spouse, then descendants, then parents, then siblings, and out to more distant relatives. An unmarried partner appears nowhere on that list.6Florida Senate. Florida Statutes Chapter 732 – Probate Code: Intestate Succession and Wills If your partner dies without a will, you inherit nothing, regardless of how long you were together or how much you paid toward shared property.
The gaps extend beyond death. Unmarried partners in Florida cannot make medical decisions for each other in an emergency without a healthcare directive, may have no claim to property titled only in the other person’s name, and cannot recover wrongful death benefits if their partner is killed. Under federal tax law, they cannot file jointly. None of these consequences shifts with time. Year forty looks the same as year one.
How to Get the Legal Status You Thought Time Would Give You
There are two real paths. One is straightforward and one takes more paperwork.
Get a Marriage License
Florida requires both parties to apply in person for a marriage license, and both must be at least 18 (a 17-year-old may marry with written parental consent if the other party is no more than two years older).7Florida Legislature. Florida Statutes 741.04 – Issuance of Marriage License There is a three-day waiting period for Florida residents, waived if both parties complete a four-hour premarital preparation course within a year of applying. The license is good for 60 days, and the ceremony can be performed by an ordained minister, any Florida judge, a clerk of the circuit court, or a Florida notary public.8Miami-Dade Clerk of Courts. Marriage Licenses That is the entire mechanism for becoming legally married in Florida.
Build Protections Without Marrying
If marriage is not what you want, you can close many of the gaps through individual legal documents. It takes more effort than a single license, and it will not replicate every spousal right, but the difference between having these papers and not having them is significant.
- A written cohabitation agreement covering ownership of property, sharing of expenses, and division of assets if the relationship ends. Florida courts generally enforce written contracts between adults on these terms.
- A will or trust naming your partner. Without one, Florida’s intestate rules give them nothing.6Florida Senate. Florida Statutes Chapter 732 – Probate Code: Intestate Succession and Wills
- A healthcare surrogate designation authorizing your partner to make medical decisions if you are incapacitated.
- A durable power of attorney letting your partner manage your finances if you cannot.
Even together, these documents leave some gaps that only marriage closes, including joint federal tax filing and spousal Social Security benefits.9Internal Revenue Service. Filing Status Still, for couples who prefer not to marry, this framework is the practical answer to the problem people mistakenly hope common law marriage will solve.
