Mississippi's Unlawful Cohabitation Statute Explained

Is it illegal to live together unmarried in Mississippi?
On paper, yes. Mississippi Code § 97-29-1 still punishes a man and woman who "unlawfully cohabit, whether in adultery or fornication," with a fine of up to $500 each and up to six months in county jail. Habitual intercourse can be proved by circumstances. Prosecutions are rare, and Lawrence v. Texas casts doubt on its use against consenting adults.

What does Mississippi Code 97-29-1 say?
Mississippi Code § 97-29-1 makes it a crime for a man and woman to live together unlawfully in a sexual relationship outside marriage. The section is titled "Adultery and fornication; unlawful cohabitation" and appears, without any repeal note, in the 2025 edition of the Mississippi Code of 1972 published by Justia [1]. It is the first section of the general article of Chapter 29 of Title 97, the criminal title of the code [2].
The section has two sentences of substance. The first sets the offense and the penalty: a man and woman who unlawfully cohabit, in adultery or in fornication, are each subject to a fine and a county jail term [1]. The second sentence relaxes the proof: the couple need not live together publicly as husband and wife, and the offense may be shown by circumstances that point to habitual sexual intercourse [1].
The text does not define "adultery" or "fornication" itself. In ordinary legal usage, adultery involves at least one partner who is married to someone else, while fornication involves two unmarried people. Section 97-29-1 treats both situations the same way once the relationship amounts to cohabitation.
A practical caveat applies to anyone reading the statute online. Free versions such as Justia's reproduce the code but warn that they may not be the most recent text and that official sources should be checked [1]. For this article, the 2025 edition was the latest available, and it showed the section unchanged.
Cohabitation and fornication statutes in four Southern states (status checked October 23, 2026)
| State | Statute | Conduct covered | Maximum penalty | Status |
|---|---|---|---|---|
| Mississippi | Miss. Code § 97-29-1 | A man and woman who unlawfully cohabit in adultery or fornication; habitual intercourse may be proved by circumstances | $500 fine each and six months in county jail | In the code (2025 edition) |
| North Carolina | G.S. 14-184 | A man and woman not married to each other who associate, bed and cohabit together | Class 2 misdemeanor: up to 60 days and $1,000 | In the code; held unconstitutional by a county trial judge in 2006 |
| South Carolina | S.C. Code §§ 16-15-60 to 16-15-80 | Living together with intercourse, or habitual intercourse, between unmarried people (fornication) or where one is married (adultery) | $100 to $500 fine, six months to one year, or both | In the code |
| Virginia | Va. Code § 18.2-344 (former) | Voluntary intercourse by an unmarried person | Class 4 misdemeanor: fine up to $250 | Held unconstitutional in 2005; repealed by Acts 2020, c. 122 |
Where does the statute come from?
The offense is older than the Civil War. The history note traces it to Hutchinson's Code of 1848 (chapter 64, article 1), then through the codes of 1857, 1871, 1880, 1892 and 1906, Hemingway's Code of 1917 and the codes of 1930 and 1942 [1]. The 1942 code numbered it § 1998 before the 1972 recodification gave it its current number [1].
The history note lists only code compilations, not later session laws [1]. That pattern suggests the offense has been carried forward with each new code rather than rewritten by a modern session law, including the $500 ceiling on the fine.
Mississippi's approach, which targets a shared household rather than an isolated act, resembles that of North Carolina, whose cohabitation law dates from an 1805 act [9]. Our article on North Carolina's cohabitation law traces that parallel history.
What counts as unlawful cohabitation?
Unlawful cohabitation under § 97-29-1 means a man and woman living together in a sexual relationship that is either adulterous or fornicatory [1]. Several features of the text shape its reach. It names "any man and woman," so the wording concerns opposite-sex couples only. It requires cohabitation, and it qualifies that cohabitation as "unlawful," which ties it to the absence of a valid marriage between the two people.
The second sentence is what makes the statute distinctive. Prosecutors do not have to show that the couple held themselves out as husband and wife or shared a home openly; circumstantial evidence of habitual sexual intercourse is enough [1]. The repeated, ongoing nature of the relationship is therefore central. On the wording alone, a single act of intercourse does not fit the definition, because the section speaks of cohabitation and habitual relations.
The section does not define "cohabit," and its precise meaning depends on how courts read it. No recent Mississippi appellate ruling on its scope was found in preparing this article, so the outer limits of the offense remain unclear.
What penalties does the law set?
The law sets a fine of up to $500 for each partner and up to six months in the county jail [1]. The section joins the two penalties with "and," so it provides for both a fine and a jail term, each with a ceiling rather than a floor. A 2020 CNN report on fornication laws described the Mississippi penalty in the same terms [6].
These figures place Mississippi near the middle of the states that keep such laws. North Carolina classes cohabitation as a Class 2 misdemeanor [9], while South Carolina allows a fine of $100 to $500, a prison term of six months to one year, or both, for adultery or fornication [10]. Virginia's former fornication statute carried only a fine of up to $250 before its repeal [11].
Because each partner faces a separate fine, the statute frames the offense as shared conduct. Both people are equally liable; the text makes no distinction between the married and the unmarried partner in an adulterous relationship.
What other morals offenses sit in the same chapter?
Section 97-29-1 opens a list of related morals offenses that remain in the Mississippi code. The 2025 edition of the general article includes adultery and fornication between a teacher and a pupil (§ 97-29-3), between persons forbidden to intermarry (§ 97-29-5) and between a guardian and a ward (§ 97-29-7), as well as "going out of state to marry" (§ 97-29-9) [2]. The same article lists bigamy, incest, the seduction of a woman over eighteen by a promise of marriage (§ 97-29-55) and "unnatural intercourse" (§ 97-29-59) [2].
Section 97-29-11 deals with a person who becomes the natural parent of a second child born outside marriage, under the heading "illegitimate children" [2]. Together these sections show how much of nineteenth-century sexual morality the code still records, even where enforcement has faded.
Lawmakers occasionally try to revise this chapter, without success so far. In the 2026 regular session, Representative Jeramey Anderson introduced House Bill 730 to remove the word "mankind" from the unnatural intercourse statute; it was referred to the House Judiciary B committee on January 16, 2026, and died there on February 3, 2026 [7]. No bill to repeal § 97-29-1 was identified for the 2024 to 2026 sessions, although that point could not be confirmed against the official session laws.
Is the law enforced today?
The law is rarely enforced, and the best-documented recent case ended in dismissal. On July 1, 2010, in Noxubee County, a 33-year-old man was charged with adultery after his wife pressed charges, and a 30-year-old woman was charged with fornication [3]. Both were released the same day on a $1,000 bond, and a Noxubee County Justice Court judge later dismissed the charges [3]. The Columbus newspaper The Dispatch called it "a rarely enforced state law" in its review of the year's crime news [3]. The case also shows how such charges tend to arise: not through police investigation, but through a private complaint, here by the spouse of one of the people charged [3].
The constitutional backdrop explains why. On June 26, 2003, in Lawrence v. Texas, the U.S. Supreme Court ruled 6 to 3 for the petitioners: five justices held that adults have a liberty interest, protected by the Due Process Clause, in private and consensual intimate conduct, overruling Bowers v. Hardwick, and Justice O'Connor concurred in the judgment on equal-protection grounds [4]. The majority stressed that the case did not involve minors, coercion, public conduct or prostitution [4]. Justice Antonin Scalia's dissent named laws against fornication and adultery among those the ruling would put in doubt [4].
In 2006, the Christian Science Monitor listed Mississippi among seven states that still banned unmarried cohabitation [5]. A singles' rights group quoted in that article estimated that 1.6 million Americans living in those seven states were technically breaking the law [5]. Arizona and New Mexico, the same article noted, had already abolished their cohabitation laws a few years earlier [5]. Whether a Mississippi court would apply Lawrence to strike down § 97-29-1 has not been settled by any published appellate ruling found for this article. For the reasoning that led other courts to do so, see our page on Lawrence v. Texas and fornication laws.
Lawrence leaves the state free to punish what the Supreme Court set aside: conduct involving minors, coercion, public acts and prostitution [4]. Mississippi addresses those situations through other statutes in the same title, such as the indecent exposure and prostitution sections listed in Chapter 29 [2].
Adultery still matters in Mississippi family law, which gives the statute a civil echo. Section 93-5-1 lists adultery among the grounds for divorce, unless it was committed by collusion to obtain a divorce or the spouses kept living together after the complaining spouse learned of it [8].
How does Mississippi compare with other Southern states?
Mississippi is one of a shrinking group of Southern states that still punish unmarried cohabitation. North Carolina keeps G.S. 14-184, which makes it a Class 2 misdemeanor for a man and woman not married to each other to bed and cohabit together [9]. South Carolina keeps §§ 16-15-60 to 16-15-80, which define fornication as living together with intercourse or habitual intercourse between two unmarried people [10]. Our page on South Carolina's adultery and fornication statutes covers those definitions.
Other states have cleared their codes. Virginia repealed its fornication statute by Acts 2020, chapter 122 [11], fifteen years after its Supreme Court held it unconstitutional. Florida dropped the cohabitation language from its lewdness statute in 2016, so that section 798.02 now covers only open and gross lewdness [13][14]. Outside the South, Massachusetts repealed its fornication statute in 2018 and Utah in 2019 [6], and Idaho repealed both fornication and adultery through Senate Bill 1325, signed on March 22, 2022 [12].
Mississippi's statute stands out in two ways. It provides for both a fine and a jail term rather than a choice between them, and it lets prosecutors rely on circumstantial evidence of habitual intercourse even when the couple do not live together publicly [1]. As of October 2026, it remains in the code, rarely used but never repealed.
Frequently asked questions
Can you be fined for living together in Mississippi?
In theory, yes. Mississippi Code § 97-29-1 provides for a fine of up to $500 for each partner, plus up to six months in county jail, when a man and woman unlawfully cohabit in adultery or fornication. In practice, charges are very rare, and the last widely reported case, in Noxubee County in 2010, was dismissed.
Does the law apply to same-sex couples?
Not on its wording. Section 97-29-1 refers only to "any man and woman" who unlawfully cohabit. Since Lawrence v. Texas (2003), private and consensual intimate conduct between adults is constitutionally protected regardless of the partners' sex.
Is adultery a crime in Mississippi?
Yes, when it takes the form of cohabitation. Section 97-29-1 punishes a man and woman who unlawfully cohabit "in adultery or fornication," and habitual intercourse can be proved by circumstances. Adultery is also a ground for divorce under § 93-5-1.
Does a single act of sex outside marriage violate § 97-29-1?
Not on the statute's wording. The offense is framed as unlawful cohabitation, and the alternative proof it allows is evidence of habitual sexual intercourse. An isolated act does not match either element, although no recent appellate ruling defining the limits was found.
Has anyone been arrested under the law recently?
Yes, at least once in recent memory. On July 1, 2010, a man was charged with adultery and a woman with fornication in Noxubee County; both posted a $1,000 bond, and a Justice Court judge dismissed the charges. No later case was found in the sources reviewed.
Has Mississippi repealed its fornication law?
No. Section 97-29-1 appears in the 2025 edition of the Mississippi Code without any repeal note. The only 2026 bill identified that touched the same chapter, House Bill 730 on the unnatural intercourse statute, died in committee on February 3, 2026.
Is adultery a ground for divorce in Mississippi?
Yes. Mississippi Code § 93-5-1 lists adultery among the grounds for divorce. It does not apply if the adultery was committed by collusion to obtain a divorce, or if the spouses continued to live together after the complaining spouse learned of it.
