Is Adultery a Crime in Florida? Legal Consequences Explained

Adultery can have consequences in Florida, but they are not all the same. Florida statutes still describe certain adultery-related conduct as a misdemeanor, while divorce law focuses on whether a marriage is irretrievably broken and how an affair affected finances or children. The practical result depends on the facts, the evidence, and the legal issue involved. Here is what Florida law says about criminal penalties, divorce, alimony, property, and parenting.

Is Adultery a Crime in Florida?

Florida law includes a statute that makes “living in open adultery” a second-degree misdemeanor. Florida Statutes § 798.01 says a person who lives in open and notorious adultery commits that offense. The wording matters: the statute addresses open, notorious conduct, not simply the fact that a married person had a private affair.

A related statute, § 798.02, addresses “open and gross lewdness and lascivious behavior.” It also classifies the conduct it covers as a second-degree misdemeanor. These statutes remain in Florida’s published laws, but their existence does not mean every affair leads to an arrest or prosecution. Enforcement is uncommon, and whether a particular situation falls within a statute depends on its specific facts and the law as courts apply it.

There is an important constitutional dimension. In Lawrence v. Texas, the U.S. Supreme Court held that the Constitution protects certain private, consensual sexual conduct between adults from criminal punishment. That decision is relevant to discussions of older morality-based laws, but it should not be treated as a blanket ruling that automatically erases every adultery statute. The legal status and application of a statute can require case-specific analysis.

Practical takeaway: Florida has adultery-related criminal language on the books, but a person should not assume either that an affair is routinely prosecuted or that the statute can never apply. A Florida criminal-defense attorney can assess a particular situation and any constitutional issues.

What Are the Criminal Penalties?

Florida classifies a second-degree misdemeanor as the state’s least serious misdemeanor level. Under Florida Statutes §§ 775.082 and 775.083, the general maximum penalties are up to 60 days in jail and a $500 fine. Those are maximum statutory limits, not an automatic sentence. The actual outcome in a case can depend on the charge, available evidence, prior record, and other circumstances.

A charge would also require the state to prove the elements of the offense beyond a reasonable doubt. For § 798.01, the words “open and notorious” are central to the statutory description. A private allegation of infidelity, standing alone, does not automatically establish that a person was “living in open adultery.” Whether the evidence meets the legal standard is a question for the criminal process.

Because these statutes are unusual and prosecutions are rare, online descriptions sometimes overstate the certainty of either criminal liability or constitutional protection. Anyone contacted by law enforcement, served with a summons, or charged should avoid discussing the facts publicly and seek advice from a licensed Florida attorney.

How Adultery Affects a Florida Divorce

Florida is a no-fault divorce state. Under Florida Statutes § 61.052, a court may dissolve a marriage when it finds that the marriage is irretrievably broken, or that one spouse has been mentally incapacitated for the required period. A spouse generally does not need to prove adultery to obtain a divorce, and an affair does not automatically prevent the other spouse from ending the marriage.

That does not mean adultery is irrelevant in every divorce. Florida law allows courts to consider certain consequences of an affair when deciding financial or parenting issues. The key distinction is often between the affair itself and its measurable effects—for example, whether marital money was spent on a relationship or whether a parent’s conduct affects a child’s welfare.

Alimony and an Affair

Florida Statutes § 61.08 directs courts to consider multiple factors when deciding alimony. These include each spouse’s financial resources, the length of the marriage, the parties’ standard of living, and their earning capacity. The statute also permits the court to consider adultery by either spouse and the circumstances surrounding it.

Adultery does not automatically entitle the faithful spouse to alimony, nor does it automatically disqualify the spouse who had an affair. The court evaluates the full financial picture under the statute. The affair’s circumstances may be considered alongside the other factors, but the result is not a fixed penalty for marital misconduct.

For instance, an affair that involved little or no use of marital funds may raise different financial questions from one that involved substantial spending. Even then, the court must apply Florida’s alimony law to the evidence and circumstances in the case. The law does not set a standard dollar amount or formula based solely on infidelity.

Marital Property and Spending on an Affair

Florida courts generally distribute marital assets and liabilities under the equitable-distribution framework in Florida Statutes § 61.075. Equitable distribution begins with the statutory process for identifying and valuing marital and nonmarital property. Courts generally start from an equal distribution of marital assets and liabilities, but the statute allows unequal distribution when relevant factors support it.

One factor is whether a spouse intentionally wasted, depleted, or otherwise dissipated marital assets after the filing of the petition or within the two years before it. Spending marital money on an affair may become relevant if the evidence shows qualifying dissipation under the statute. The affair alone does not automatically change the property division. The issue is whether there was a financial impact the court may consider, and what the evidence establishes.

Useful records may include bank and credit-card statements, payment-app histories, receipts, travel records, and documentation of transfers. Records should be obtained lawfully. A spouse should not access another person’s accounts without authorization or use spyware, impersonation, or other potentially unlawful methods to gather evidence.

Child Custody and Parenting Decisions

Florida uses the term parental responsibility and time-sharing rather than relying only on the word “custody.” Under Florida Statutes § 61.13, parenting decisions must be based on the child’s best interests. Courts consider a range of factors, including each parent’s capacity to support the child’s relationship with the other parent, the child’s needs, and relevant evidence about each parent’s conduct.

An affair does not automatically make a parent unfit or determine a time-sharing schedule. A court’s concern is whether the conduct has a meaningful connection to the child’s welfare or to a statutory best-interest factor. For example, evidence that a child was exposed to unsafe circumstances or that a parent’s choices seriously disrupted the child’s care may matter in a way that an adult relationship, by itself, may not.

Parents should avoid using children as messengers, asking them to gather evidence, or making disparaging statements about the other parent in front of them. Such behavior can increase conflict and may be relevant to the court’s assessment of the parents’ ability to meet the child’s needs.

Does a Private Affair Count as “Open Adultery”?

The phrase “open and notorious” in § 798.01 distinguishes the statute’s wording from a broad rule that every secret extramarital relationship is a crime. However, Florida’s statute does not provide a simple checklist that resolves every possible situation. Whether conduct meets the statutory description would depend on the facts and applicable legal interpretation.

There is also a difference between proof relevant to a divorce and proof sufficient for a criminal charge. A text message, photograph, or financial record might be offered in a family-law dispute for a specific purpose, but that does not automatically establish every element of a criminal offense. Evidence rules and legal standards differ between proceedings.

Criminal Case Versus Divorce Case

Common Misunderstandings About Florida Adultery Law

• “Every affair is automatically a crime.” The criminal statute uses the phrase “living in open and notorious adultery”; it does not simply say that any extramarital relationship automatically results in prosecution.
• “Florida has no adultery law.” Section 798.01 remains in the Florida Statutes, although the existence of statutory language does not mean it is commonly enforced.
• “Adultery guarantees alimony.” Alimony depends on statutory factors and the circumstances of the case. Infidelity alone does not guarantee an award.
• “The parent who had an affair loses custody.” Parenting decisions are based on the child’s best interests, not an automatic punishment for a parent’s relationship.
• “A spouse can take money from the other spouse’s accounts to prove an affair.” Evidence gathering must follow the law. Unauthorized account access or surveillance can create separate legal problems.

What to Do if Adultery Is Part of a Florida Legal Dispute

First, identify the issue: a possible criminal investigation, divorce, alimony, property division, or parenting plan. The relevant legal standards differ, so evidence that matters in one setting may have limited value in another.

Keep financial records and communications that are lawfully available, and avoid deleting or altering relevant material. Do not threaten a spouse, publish private information, or confront another person in a way that could escalate the situation. If there is a criminal inquiry, speak with a criminal-defense lawyer before answering substantive questions. For divorce or parenting issues, a Florida family-law attorney can explain which facts are relevant and what documentation is appropriate.

Florida statutes can be reviewed through the Florida Legislature’s official online statutes, including §§ 61.052, 61.075, 61.08, 61.13, 775.082, 775.083, and 798.01–798.02.
