Discovering that a spouse has been unfaithful is one of the most painful moments in a marriage, and it raises immediate legal questions about property division, spousal support, child custody, and whether the betrayal carries any criminal consequences.
The answers depend on Ohio divorce laws and how the court weighs marital misconduct. In this guide, our experienced Columbus divorce attorneys explain how adultery is treated under Ohio law and what an adultery divorce typically looks like in practice.
Is Adultery a Crime in Ohio?
No. Decades ago, there was a law imposing criminal penalties for adultery, but that law was officially repealed in 1974. Ohio law treats infidelity very differently from how it did decades ago. No one can be arrested, fined, or jailed simply for cheating on a spouse. So if you are asking whether adultery is illegal in Ohio, the short answer is no, it is not a criminal offense under current state law.
Does Cheating Matter in a Divorce in Ohio?
Even though adultery is not a crime, it still has a defined place in Ohio family law. Whether cheating matters in a divorce depends largely on how the unfaithful spouse behaved during the marriage and how it affected the family's finances.
Adultery as a Fault-Based Ground for Divorce
Under Ohio law, adultery is one of the recognized fault-based grounds for divorce, alongside extreme cruelty, gross neglect of duty, habitual drunkenness, and willful absence. Most divorces in Ohio still proceed under no-fault grounds, such as incompatibility or living separate and apart for one year, but a spouse may choose to file on adultery when the facts support it.
Proving Adultery in Ohio Divorce Cases
To use adultery as a ground for divorce, the filing spouse must present clear and convincing evidence of voluntary sexual conduct between their spouse and a third party. Acceptable proof may include text messages, photographs, financial records, hotel receipts, or witness testimony. Suspicion alone is not enough to meet the legal standard.

Ohio Divorce Laws on Adultery and Property Division
Ohio is an equitable distribution state. That means marital property and debts are divided fairly, though not always equally, regardless of who caused the breakdown of the marriage.
Equitable Distribution Under Ohio Law
In Ohio, courts divide marital assets based on factors like the length of the marriage, each spouse's contributions, and the economic circumstances of both parties. Adultery, on its own, generally does not entitle the faithful spouse to a larger share of the marital estate.
When an Affair Can Affect Property Division
The exception involves financial misconduct. If the unfaithful spouse spent significant marital funds on the affair, such as gifts, vacations, or hotel stays, it can qualify as dissipation of marital assets. The court may then adjust the property division to compensate the innocent spouse, which is one reason the divorce process in Ohio can vary widely in length.
How Adultery Affects Spousal Support in Ohio
Spousal support, sometimes called alimony, depends on several factors that a judge looks at together. These include each spouse's income and earning capacity, the length of the marriage, and the standard of living the couple shared during the marriage.
While fault is not the primary driver of spousal support decisions, Ohio courts retain discretion to weigh marital misconduct as part of the broader picture. A judge may consider an affair when the conduct affected the marital finances or when fairness requires it, though most awards still focus on need, ability to pay, and economic disparity between the spouses.
Does Cheating Affect Child Custody in Ohio?
Child custody decisions follow a separate legal standard. Ohio courts focus on the child's best interests, not on which parent caused the marriage to end.
The Child's Best Interest Standard
When deciding child custody arrangements, courts evaluate parenting ability, stability, the child's relationship with each parent, and the home environment. Adultery itself typically has no bearing on custody decisions because it does not, by default, reflect on parenting capability.
When an Affair Becomes Relevant to Custody
A cheating spouse's behavior may matter if the affair directly affects the child. Examples include exposing the child to a partner with a history of abuse, substance use, or criminal conduct, or neglecting parental duties because of time spent with the third party. In those situations, the court may consider how the affair impacts the child's safety and well-being.
Should You File an Adultery Divorce in Ohio?
Many spouses assume that filing on adultery grounds will lead to a better outcome, but that is not always the case. Choosing fault-based grounds requires careful thought about strategy, evidence, and costs.
Pros and Cons of Filing on Adultery Grounds
Filing under adultery can support a claim for financial misconduct or dissipation, but fault-based divorces often take longer, cost more, and require deeper evidence-gathering than no-fault filings. Many Ohio spouses achieve favorable outcomes through incompatibility grounds while raising the affair as part of the dissolution arguments.

Practical Steps If Your Spouse Has Cheated
If you suspect or have confirmed infidelity, preserve evidence safely, document any unusual financial activity, and avoid confronting the third party in ways that could expose you to legal claims. Most importantly, consult an experienced divorce attorney before making decisions that may affect your divorce settlement. If you are still weighing the bigger picture, our guide on whether you should get a divorce walks through the most important factors to consider.
