Florida is a pure no-fault divorce state, meaning you do not need to prove adultery to obtain a divorce under Fla. Stat. § 61.052. However, adultery can significantly impact your divorce outcome in three critical areas: alimony awards under Fla. Stat. § 61.08, property division through dissipation claims under Fla. Stat. § 61.075, and child custody when the affair directly harmed the children. This guide explains exactly how Florida courts treat infidelity in 2026 divorce proceedings, what evidence you need, and the financial consequences your cheating spouse may face.
| Key Facts | Details |
|---|---|
| Filing Fee | $408 + $10 summons (as of April 2026) |
| Waiting Period | 20 days minimum |
| Residency Requirement | 6 months for at least one spouse |
| Grounds | No-fault only (marriage irretrievably broken) |
| Property Division | Equitable distribution (not 50/50) |
| Adultery Criminal Status | Second-degree misdemeanor (rarely enforced) |
Is Adultery a Ground for Divorce in Florida?
Adultery is not a ground for divorce in Florida because Florida eliminated all fault-based grounds decades ago. Under Fla. Stat. § 61.052, the only two grounds for divorce are: (1) the marriage is irretrievably broken, or (2) one spouse has been mentally incapacitated for at least three years. You cannot file for divorce in Florida based on adultery, abandonment, cruelty, or any other fault-based reason. Your spouse also cannot prevent the divorce by contesting the allegation that the marriage is irretrievably broken.
This no-fault framework means that proving your spouse committed adultery will not automatically entitle you to a divorce or give you any advantage in obtaining one. Every Florida divorce proceeds on the same legal basis regardless of why the marriage ended. However, the practical effects of adultery appear in the financial and custodial aspects of your case, where Florida courts do consider marital misconduct.
What Does No-Fault Actually Mean?
No-fault divorce eliminates the need to prove wrongdoing to end your marriage. In Florida, you simply need to declare that your marriage is irretrievably broken. The court will not require you to prove infidelity, physical abuse, or neglect as a prerequisite to dissolving the marriage. This system reduces litigation costs, speeds up proceedings, and removes adversarial blame from the dissolution process itself.
The no-fault framework does not mean that fault never matters in Florida divorces. Courts can still consider adultery and other misconduct when making decisions about alimony, property distribution, and parenting arrangements. The distinction is between grounds for divorce (where fault is irrelevant) and terms of divorce (where fault may be highly relevant).
How Adultery Affects Alimony in Florida
Florida courts may consider adultery when determining alimony awards under Fla. Stat. § 61.08(1), which explicitly states that the court may consider "the adultery of either spouse and any resulting economic impact." This statutory language means adultery becomes most significant when the affair caused financial harm to the marriage. If a cheating spouse spent $50,000 on a paramour over two years, that dissipation of marital funds will directly influence alimony calculations. Courts in Florida cannot use alimony as punishment for bad behavior, but they can account for the economic consequences of that behavior.
When Adultery Increases Alimony Awards
Adultery affects alimony most dramatically when marital funds were spent on the affair. Florida courts have increased alimony awards to innocent spouses when evidence shows:
- Direct spending on a paramour (gifts, vacations, dinners, jewelry)
- Rent or mortgage payments for a separate residence used for the affair
- Financial support provided to the affair partner or their children
- Business opportunities diverted to benefit the paramour
- Medical expenses, credit card debt, or loans incurred due to the affair
The burden of proof falls on the spouse claiming adultery affected marital finances. You must demonstrate with bank statements, credit card records, and other financial documentation that marital funds were used for the affair. Vague allegations without documentary evidence rarely persuade Florida courts to adjust alimony awards.
Types of Alimony Available in Florida
Following the 2023 alimony reform under SB 1416, Florida recognizes four types of alimony:
| Alimony Type | Duration | Purpose |
|---|---|---|
| Temporary | During proceedings | Support while divorce is pending |
| Bridge-the-Gap | Up to 2 years | Short-term transition assistance |
| Rehabilitative | Up to 5 years | Education or training to become self-supporting |
| Durational | Varies by marriage length | Ongoing support for set period |
Florida law now prohibits permanent alimony and caps durational alimony based on marriage length: 50% of marriage length for short-term marriages (less than 10 years), 60% for moderate-term marriages (10-20 years), and 75% for long-term marriages (20+ years). The 2023 reform also prohibits alimony awards that would leave the paying spouse with less net income than the receiving spouse.
How Adultery Affects Property Division in Florida
Florida follows equitable distribution for dividing marital property under Fla. Stat. § 61.075, which begins with a presumption of equal division but allows courts to deviate based on relevant factors. Adultery affects property division primarily through dissipation of assets claims, where one spouse intentionally wasted marital funds on the affair. The statute specifically lists "intentional dissipation, waste, depletion, or destruction of marital assets after the filing of the petition or within 2 years prior to the filing" as a factor justifying unequal distribution.
Proving Dissipation of Marital Assets
To successfully claim dissipation due to adultery in Florida, you must prove:
- Your spouse engaged in an extramarital affair
- Marital funds were spent on or because of the affair
- The spending occurred within 2 years before filing or after filing
- The amount spent can be quantified with reasonable certainty
Florida courts have ordered unequal property distributions when cheating spouses spent marital money on luxury gifts, expensive trips, separate apartments, vehicles for paramours, or business investments benefiting affair partners. The innocent spouse may receive a larger share of remaining marital assets to compensate for the dissipated funds.
What Counts as Dissipation?
Florida courts consider the following expenditures as potential dissipation related to adultery:
- Cash withdrawals with no legitimate explanation
- Credit card charges for hotels, dinners, gifts, or travel benefiting the paramour
- Funds transferred to the affair partner or their family members
- Marital property given to or used by the paramour
- Business assets or opportunities directed to benefit the affair partner
- Legal fees or settlements related to the affair (such as paternity cases)
The court will subtract proven dissipation from the cheating spouse's share of marital assets. If $100,000 in marital funds were dissipated on an affair, the innocent spouse effectively receives credit for half that amount ($50,000) in the property division calculation.
How Adultery Affects Child Custody in Florida
Adultery typically does not affect child custody in Florida unless the affair directly harmed the children's wellbeing. Under Fla. Stat. § 61.13(3), Florida courts determine custody (called "time-sharing" in Florida) based on 20 factors focused on the children's best interests. The statute includes "the moral fitness of the parents" as one factor, but Florida appellate courts have consistently held that adultery alone does not demonstrate moral unfitness for parenting.
When Adultery Does Affect Custody
Florida courts will consider adultery in custody determinations when:
- Children were exposed to inappropriate sexual conduct
- The affair partner poses a risk to child safety
- Parenting time was neglected due to the affair
- Children experienced emotional trauma from witnessing the affair
- The cheating parent prioritized the affair over children's needs
- The affair partner has a criminal history involving children
The landmark Florida case Willis v. Willis, 818 So. 2d 530 (Fla. 2nd DCA 2002) established that courts should focus on whether parental conduct "has had or is reasonably likely to have an adverse impact" on children. Hypothetical concerns about a parent's morality without evidence of actual harm to children rarely justify custody modifications.
Best Interest Factors in Florida
Florida statute lists 20 factors courts must consider when determining time-sharing arrangements:
- Each parent's demonstrated capacity and willingness to facilitate a close relationship with the other parent
- The anticipated division of parental responsibilities after litigation
- Each parent's ability to determine, consider, and act upon the child's needs
- The length of time the child has lived in a stable, satisfactory environment
- The geographic viability of the parenting plan
- The moral fitness of the parents
- The mental and physical health of the parents
- The child's home, school, and community record
- The reasonable preference of the child (if sufficient maturity)
- Evidence of domestic violence, sexual violence, child abuse, or abandonment
A parent's adultery matters only if it connects to these factors through demonstrated harm or risk to the children.
Is Adultery a Crime in Florida?
Adultery remains technically illegal in Florida under Fla. Stat. § 798.01, which classifies "living in an open state of adultery" as a second-degree misdemeanor punishable by up to 60 days in jail and a $500 fine. This 1874 statute has remained on the books despite being considered largely obsolete by legal experts. Prosecutions for adultery are almost non-existent in modern Florida, with no recent records of criminal charges for consensual adult affairs.
The statute requires "living in an open state of adultery," which courts have interpreted to mean an ongoing, public cohabitation rather than a single affair. Both parties to the adultery can be charged under this law. Despite the theoretical criminal penalties, the practical consequences of adultery in Florida occur exclusively in divorce court through alimony adjustments, property division modifications, and custody considerations.
Proving Adultery in Florida Divorce Court
Proving adultery in Florida requires clear and convincing evidence that your spouse engaged in sexual relations outside the marriage. Because Florida is a no-fault state, you do not need to prove adultery for the divorce itself, but you may need evidence to support alimony or property claims. Florida courts accept various forms of evidence:
Acceptable Evidence of Adultery
- Text messages, emails, or social media communications
- Photographs or videos showing intimate conduct
- Hotel, restaurant, or travel receipts indicating time spent with paramour
- Credit card statements showing gifts or expenses for affair partner
- Testimony from witnesses who observed the affair
- Phone records showing extensive communication with paramour
- Private investigator reports documenting the relationship
- Admissions by the cheating spouse (verbal or written)
Evidence Standards for Financial Claims
For alimony and property division claims based on adultery, you need evidence connecting the affair to financial harm:
| Evidence Type | Purpose | How to Obtain |
|---|---|---|
| Bank statements | Show cash withdrawals and transfers | Discovery requests |
| Credit card records | Document purchases for paramour | Subpoena card companies |
| Gift receipts | Prove spending on affair partner | Text messages, email |
| Hotel/travel records | Establish affair-related expenses | Credit card statements |
| Business records | Show diversion of marital assets | Forensic accountant |
Florida courts give significant weight to documentary evidence over circumstantial evidence or testimony alone. A forensic accountant can help trace marital funds spent on an affair and quantify the total dissipation for property division calculations.
Steps to Take If Your Spouse Committed Adultery
If you suspect or have confirmed your spouse committed adultery in Florida, take these strategic steps to protect your interests:
- Document evidence of the affair without violating privacy laws
- Gather financial records showing potential dissipation of assets
- Consult with a Florida divorce attorney experienced in adultery cases
- Avoid confrontations that could escalate to domestic violence claims
- Maintain focus on children's wellbeing if custody is involved
- Consider whether the affair justifies seeking unequal property distribution
- Calculate the approximate financial impact of the affair on marital assets
- Prepare for the emotional challenges of divorce litigation
Protecting Your Financial Interests
To maximize your position in property division and alimony negotiations:
- Open a separate bank account for personal expenses (but do not hide marital assets)
- Request copies of all financial records, tax returns, and business documents
- Make copies of credit card statements showing affair-related spending
- Document any joint assets your spouse may attempt to hide or transfer
- Hire a forensic accountant if significant assets are involved
- Track ongoing spending that could constitute additional dissipation
Filing for Divorce in Florida: Requirements and Process
To file for divorce in Florida, you must meet the following requirements:
- Residency: At least one spouse must have resided in Florida for 6 months before filing under Fla. Stat. § 61.021
- Filing fee: $408 plus $10 summons fee (as of April 2026; verify with your local clerk)

Timeline for Florida Divorce
| Divorce Type | Typical Timeline | Key Factors |
|---|---|---|
| Simplified | 30-45 days | Both spouses agree, no children, no alimony |
| Uncontested | 1-3 months | Agreement on all terms, minimal court involvement |
| Contested | 6-12+ months | Disputes over assets, custody, or support |
| High-conflict | 12-24+ months | Trial required, complex financial issues |
Adultery-related financial claims often extend divorce timelines because they require additional discovery, forensic accounting, and potentially expert testimony. Cases involving significant dissipation claims may take 12-18 months to resolve.
Frequently Asked Questions
Can I get more money in my divorce if my spouse cheated in Florida?
Florida courts may award you more in alimony or property division if your spouse's adultery caused financial harm to the marriage. Under Fla. Stat. § 61.08, courts consider "the adultery of either spouse and any resulting economic impact" when determining alimony. For property division under Fla. Stat. § 61.075, you may receive a larger share if your spouse dissipated marital assets on the affair within 2 years before filing or after filing. Document all affair-related expenditures with bank statements, credit card records, and receipts.
Does adultery affect child custody in Florida?
Adultery generally does not affect child custody (time-sharing) in Florida unless the affair directly harmed the children. Under Fla. Stat. § 61.13, courts focus on 20 best interest factors centered on child wellbeing, not parental punishment. The "moral fitness" factor applies only when parental conduct has had or is likely to have an adverse impact on children. If you can prove the affair exposed children to inappropriate situations or caused documented emotional harm, courts may consider it.
Is adultery still a crime in Florida in 2026?
Yes, adultery remains technically illegal in Florida under Fla. Stat. § 798.01, classified as a second-degree misdemeanor with penalties of up to 60 days in jail and a $500 fine. However, prosecutions are virtually non-existent. This 1874 statute requires "living in an open state of adultery" (ongoing public cohabitation) rather than a single affair. Legal experts consider it obsolete, and real-world consequences of infidelity occur exclusively in divorce court through alimony and property adjustments.
How do I prove my spouse committed adultery in Florida?
To prove adultery in Florida divorce court, gather documentary evidence including text messages, emails, photographs, credit card statements, hotel receipts, and witness testimony. For financial claims, you need evidence connecting the affair to marital asset dissipation. Florida courts prefer documentary evidence over circumstantial proof. Private investigators can document affairs, and forensic accountants can trace marital funds spent on paramours. Discovery requests and subpoenas can compel production of financial records.
What is dissipation of marital assets in Florida?
Dissipation of marital assets under Fla. Stat. § 61.075 means the intentional waste, depletion, or destruction of marital property. In adultery cases, dissipation includes spending marital funds on a paramour: gifts, vacations, rent, cars, or financial support. Florida courts consider dissipation occurring within 2 years before filing or after filing when dividing property. Proven dissipation is subtracted from the cheating spouse's share of marital assets, effectively compensating the innocent spouse.
Can my spouse prevent our divorce if I committed adultery?
No, your spouse cannot prevent divorce in Florida based on your adultery or any other reason. Florida is a pure no-fault state under Fla. Stat. § 61.052, requiring only that one spouse declare the marriage irretrievably broken. Your spouse cannot successfully contest this allegation. However, your adultery may affect the terms of divorce, potentially resulting in reduced alimony, an unfavorable property division, or custody adjustments if children were harmed.
How does Florida's no-fault law affect adultery cases?
Florida's no-fault divorce law means adultery is not a ground for divorce but can still affect divorce terms. You file for divorce by declaring the marriage irretrievably broken under Fla. Stat. § 61.052, without proving fault. However, adultery may influence alimony determinations under § 61.08, property division through dissipation claims under § 61.075, and custody when children were harmed. The no-fault system separates obtaining the divorce from negotiating its financial and custodial terms.
Should I hire a private investigator to prove adultery?
Hiring a private investigator may be worthwhile in Florida divorce cases involving significant assets or contested custody. Investigators can document affairs through surveillance, photography, and background checks on paramours. Their reports serve as evidence for dissipation claims or custody modifications. However, weigh the cost ($50-150/hour) against potential benefits. If your spouse admits the affair or you have substantial documentary evidence, an investigator may be unnecessary. Consult with a family law attorney about whether investigation is strategically valuable for your specific case.
What happens if both spouses committed adultery in Florida?
When both spouses committed adultery in Florida, courts may consider both affairs when determining alimony and property division. Under Fla. Stat. § 61.08, the court considers "the adultery of either spouse" — the language allows consideration of infidelity by both parties. If both spouses dissipated marital assets on their respective affairs, courts may offset the amounts. Neither spouse gains moral high ground, but documented financial harm from either affair remains relevant to equitable distribution calculations.
How much does divorce cost in Florida when adultery is involved?
Florida divorce costs range from $500 for simple uncontested cases to $25,000+ for contested litigation. The base filing fee is $408 plus $10 summons. Adultery-related claims typically increase costs because they require additional discovery, forensic accounting ($2,500-10,000), and potentially expert testimony. Attorney fees for contested divorces average $11,000-14,000, but complex adultery cases with significant dissipation claims can exceed $25,000. Consider whether the potential financial recovery justifies the litigation expenses.
