Adultery is still a legal ground for divorce in Ohio. However, proving it rarely changes how a judge divides your property. An affair can matter in spending, parenting, and the grounds on which you can file for divorce.
Adultery Is Still a Fault Ground in Ohio
Ohio allows both fault-based and no-fault divorces. The grounds for divorce, R.C. 3105.01, list adultery, alongside extreme cruelty, gross negligence of duty, and several other grounds. Most people file for incompatibility, instead. It is faster, and keeps private details away from public court records.
There is a catch to incompatibility. It only works if your spouse is willing to accept it. If they are not, you need to find another reason, such as:
- Adultery
- Living separate and apart without cohabitation for one full year
- Extreme cruelty or gross neglect of duty, if the facts support it
The Affair Itself Won’t Shift the Property Split. The Spending Can.
Ohio starts with an equal division of marital property according to R.C. 3105.171. A judge is not supposed to give you a bigger share just because your spouse has been unfaithful.
Money spent on the affair is a different matter. The same law allows the court to compensate you if your spouse engages in financial misconduct, including wasting, hiding, or fraudulent disposal of assets. Common examples include:
- Hotel stays, trips, and gifts for the other person paid with marital funds
- Covering rent or bills for a second home
- Cash quietly moved into a separate account (usually revealed by bank records)
If the court finds misconduct, it can award you a larger share of marital property or a separate distribution award. A spouse who wilfully hides assets during the case runs the risk of more. The court can award up to three times the value of undisclosed assets.
Spousal Support Is Based on Need, Not Blame
Judges decide spousal support based on factors in R.C. 3105.18, including income, earning ability, health, length of marriage, and standard of living. Adultery is not a factor in this decision. The statute allows a court to consider other factors it deems relevant and equitable. Ohio courts generally view support as a means to meet needs, not as punishment. A spouse who has cheated may still receive support.
Custody Decisions Focus on the Children
An affair does not necessarily make someone a bad parent. When considering a divorce case, the court in R.C. 3109.04 looks at what is best for the child, including their relationships with anyone who could significantly affect their well-being, including a new partner.
Judges take note of the following situations:
- If the new partner moves in quickly or spends the night while the children are at home.
- If the relationship has pulled a parent away from school, meals, or daily routines.
- If there is a history of violence or substance abuse in the partner’s background, which is of most concern to the courts.
Gather Evidence the Right Way
Ohio courts accept circumstantial evidence of adultery. Messages sent to you, shared credit card statements, and photos taken in public places are generally admissible. Logging into your spouse’s private accounts or secretly recording conversations that you are not part of is not allowed. Ohio’s wiretapping law prohibits intercepting someone else’s communication, and this kind of evidence can harm your case.
You also can’t sue an affair partner. Ohio has eliminated lawsuits for adultery and criminal conversation under R.C. 2305.29.
