Ohio Revised Code Chapter 3105 - Divorce, Alimony, Annulment, Dissolution

Ohio recognizes both fault and no-fault grounds for divorce. The 11 grounds include incompatibility (no-fault, but either spouse can deny it), living separate and apart for one year, adultery, extreme cruelty, willful absence for one year, gross neglect of duty, habitual drunkenness, imprisonment, bigamy, fraudulent marriage contract, and out-of-state divorce by one spouse. Incompatibility is the most commonly used ground but requires both spouses to agree; if one denies it, a fault ground must be proven.

Effective: 1994

The filing spouse must have been a resident of Ohio for at least 6 continuous months immediately before filing. Additionally, the filing spouse must have resided in the county where the complaint is filed for at least 90 days. Both requirements must be met for the court to have jurisdiction over the case.

Effective: 1990

Either spouse may file a complaint for divorce or legal separation, and the other spouse may file a counterclaim for either remedy. Legal separation is available on the same grounds as divorce. Filing for legal separation does not bar either party from later seeking a divorce or annulment.

Effective: 2013

For dissolution of marriage (the cooperative, no-fault alternative to divorce), at least one spouse must have been an Ohio resident for 6 continuous months immediately before filing. Unlike divorce, there is no additional county residency requirement for dissolution.

Effective: 1990

Ohio is an equitable distribution state. The court must identify what is marital property and what is separate property, then divide marital property equally — unless equal division would be inequitable. When deviating from equal division, the court considers factors including marriage duration, each spouse's assets and liabilities, liquidity of property, economic desirability of keeping the family home for the custodial parent, retirement benefits, and any other relevant factors. Separate property includes gifts to one spouse, inheritances, premarital property, and personal injury compensation. Commingling does not destroy separate property identity if it remains traceable.

Effective: 2013

If a spouse has engaged in financial misconduct — including dissipation, destruction, concealment, nondisclosure, or fraudulent disposition of marital assets — the court may compensate the other spouse with a distributive award or a greater share of marital property. This provision protects against spouses who try to hide or waste assets before or during divorce proceedings.

Effective: 2013

Ohio allows both prenuptial and postnuptial agreements (postnuptial agreements were authorized in 2023). Spouses may enter agreements that alter their legal relations, modify or terminate an existing prenuptial or postnuptial agreement, or agree to an immediate separation with provisions for property division and support. Under §3103.061, such agreements are enforceable if in writing, signed by both spouses, entered into freely without fraud or duress, based on full financial disclosure, and not promoting divorce.

Effective: 2023

Ohio public retirement accounts (OPERS, STRS, SERS, etc.) are exempt from federal ERISA and cannot be divided by a QDRO. Instead, they must be divided by a Division of Property Order (DPO) under state law. The DPO uses a coverture fraction: the numerator is the number of years the participant was both a member and married, and the denominator is total years of service. Private retirement plans and 401(k)s are divided using standard QDROs under federal law.

Effective: 2016

Ohio courts allocate parental rights based on the best interest of the child. If no shared parenting plan is filed or found appropriate, the court designates one parent as the residential parent and legal custodian. The court considers factors including each parent's wishes, the child's wishes (if interviewed), the child's relationships and adjustment, everyone's mental and physical health, which parent is more likely to facilitate the other's parenting time, child support payment history, domestic violence history, and whether a parent plans to relocate. Ohio abolished the Tender Years Doctrine — parents have equal rights under §3109.03.

Effective: 2017

Ohio allows shared parenting (joint custody) where both parents are designated residential parents. The court considers additional factors for shared parenting including the parents' ability to cooperate and make joint decisions, each parent's willingness to encourage the child's relationship with the other parent, history of domestic violence or parental kidnapping, geographic proximity of the parents, and the guardian ad litem's recommendation. Shared parenting does not automatically mean equal time — the court determines the specific schedule.

Effective: 2017

The non-residential parent is entitled to reasonable parenting time unless it would endanger the child's health or welfare. The court establishes a specific parenting time schedule based on the child's best interest. Grandparents, relatives, and other persons may also seek companionship or visitation rights. If a parent is found in contempt for interfering with court-ordered parenting time, the court must assess court costs and reasonable attorney's fees against that parent, and may award compensatory parenting time.

Effective: 2017

A custody order cannot be modified unless the court finds a substantial change in circumstances affecting the child or a parent since the prior order, and that modification is in the child's best interest. The change must be significant — not a slight change — and was not contemplated when the original order was entered. A parent's relocation alone does not automatically justify a custody change, but a move combined with impact on the child's wellbeing or the other parent's relationship may qualify.

Effective: 2017

Ohio uses an income shares model for calculating child support. Both parents' gross incomes are combined and applied to the Basic Child Support Schedule to determine the total support obligation, which is then divided proportionally based on each parent's share of combined income. Standardized worksheets (JFS 07768 for sole/shared parenting, JFS 07769 for split parenting) must be used by all courts. The schedule and worksheets are revised at least every 5 years.

Effective: 2019

When a parent has court-ordered parenting time of 90 or more overnights per year, the child support obligation is automatically reduced by 10%. This reduction can be combined with other deviations. However, if the obligor fails to actually exercise the court-ordered parenting time without just cause, the court may eliminate the 10% reduction at the other parent's request. Under §3119.231, the court must also consider whether an additional deviation beyond the 10% is warranted.

Effective: 2019

The court may deviate from the calculated child support amount if it would be unjust, inappropriate, or not in the child's best interest. Deviation factors include special needs of the child, other court-ordered payments, extended parenting time costs, extraordinary travel expenses, income disparity between households, benefits from a parent's remarriage, and extraordinary childcare costs. The court must state in writing the specific reasons for any deviation.

Effective: 2019

After dividing property under §3105.171, the court may award reasonable spousal support to either spouse. The court considers 14 factors including both parties' income, relative earning abilities, ages and health, retirement benefits, marriage duration, standard of living during the marriage, education levels, contributions to the other spouse's earning ability, time needed for the supported spouse to become self-sufficient, and tax consequences. Support terminates upon the death of either party unless the order states otherwise. Modification requires a substantial change in circumstances and is only allowed if the original decree specifically authorizes it.

Effective: 2013

Either parent or a child support enforcement agency may request a review and modification of a child support order. The court will modify the order if there has been a substantial change in circumstances not contemplated at the time of the original order or last modification. The modified amount must comply with the current guidelines and worksheet unless those amounts would be unjust or not in the child's best interest. A change of 10% or more from the existing order typically constitutes a substantial change.

Effective: 2019

Dissolution is Ohio's cooperative, no-fault path to ending a marriage. Both spouses must jointly file a petition with a complete separation agreement covering property division, spousal support, and (if applicable) parenting and child support. Both spouses must appear in court between 30 and 90 days after filing to acknowledge under oath that they entered the agreement voluntarily. If the case went through collaborative family law (§3105.41–3105.54), the 30-day minimum waiting period may be waived.

Effective: 2013

The court may grant a divorce upon proof of grounds and dissolve the marriage, releasing both parties from their obligations. Separation agreements — including those providing support for children 18 or older — are enforceable by the court. A voluntarily entered separation agreement may be enforced if the court determines it is in the interests of justice and equity. Upon granting a divorce, each party is barred from all dower rights in the other's real estate.

Effective: 2013

At any time after 30 days from service of summons in a divorce, annulment, or legal separation case, the court may order the parties to undergo conciliation for up to 90 days. If children are involved, the court may also order family counseling during or after the proceedings. The divorce case cannot proceed to a hearing until the ordered conciliation or counseling has concluded and been reported to the court. This is discretionary — not mandatory in every case.

Effective: 1990

Income withholding for child support is available from the moment a support order is issued or modified. The employer must begin withholding no later than 14 business days after receiving the notice and must send the withheld amount to the Ohio Child Support Payment Central within 7 business days after the employee is paid. Employers cannot take adverse action against an employee because of a child support withholding order under §3121.39.

Effective: 2019

Any family or household member (spouse, former spouse, cohabitant, parent, dating partner) may petition for a civil protection order (CPO) against an abuser. The court may issue an ex parte order immediately upon finding immediate and present danger, followed by a full hearing within 7 court days. Relief includes evicting the abuser, exclusive use of the residence, temporary custody and support, no-contact orders, counseling requirements, and protection of companion animals. CPOs last up to 5 years and can be renewed. No filing fee is charged, and a victim advocate may accompany the petitioner at all stages.

Effective: 2023

Ohio's Collaborative Family Law Act (effective 2013) provides a structured alternative to litigation. Both parties and their attorneys sign a participation agreement committing to resolve the case without court intervention. If the collaborative process fails, the collaborative lawyers must withdraw and the parties must retain new attorneys for litigation. Communications during the process are confidential and privileged. Completing a collaborative process may waive the 30-day waiting period for dissolution under §3105.64.

Effective: 2013

When a divorce is granted, the court must restore a party's former name if that person requests it. This applies to any name the person had before the marriage — not just a maiden name. The other spouse cannot block or force the name change. The request should be included in the divorce petition or raised during proceedings. After the decree, the certified divorce decree serves as proof for updating Social Security cards, driver's licenses, and other documents without a separate probate court filing.

Effective: 1978

A prenuptial or postnuptial agreement is enforceable in Ohio if it is in writing, signed by both spouses, entered into freely without fraud, duress, coercion, or overreaching, and based on full disclosure of both spouses' finances. The terms must not promote or encourage divorce. If a spousal support waiver in a prenuptial agreement would leave one party destitute or on public assistance, the court may find that provision unconscionable and award spousal support under §3105.18 factors.

Effective: 2023

Ohio public employee retirement benefits (OPERS, STRS, SERS, OP&F, SHPRS) are divided using a Division of Property Order (DPO) rather than a federal QDRO. The DPO uses a coverture fraction: years of concurrent marriage and service membership divided by total years of service at retirement. Private employer retirement plans and 401(k)s follow federal ERISA rules and are divided by QDRO. Military pensions are governed by the federal Uniformed Services Former Spouses' Protection Act.

Effective: 2016
