Prepare for an Ohio support discussion

This guide does not estimate support amount, duration or eligibility. The material below is a starting point for checking sources and preparing questions, not a determination of your rights.

  1. Bring income records, recurring expenses, debts and existing support orders for both households.
  2. Identify which dates, local rules and circumstances your adviser needs to check.
  3. Ask which sources apply to your situation and what evidence is missing.

To explore cash flow using a payment you choose, use the support budget comparison. It does not recommend a payment.

The 14 §3105.18(C)(1) Factors

  • Income of the parties, from all sourcesIncluding income from property divided under §3105.171.
  • Relative earning abilities of the partiesNot just current income — realistic earning capacity.
  • Ages and physical, mental, and emotional conditionsHealth and age of both spouses.
  • Retirement benefits of the partiesWhat each spouse has coming in retirement.
  • Duration of the marriageFeeds the informal duration rule of thumb.
  • Custodial parent's ability to work outside the homeWhether outside employment is inappropriate for the custodial parent.
  • Standard of living during the marriageThe lifestyle the marriage established.
  • Relative extent of education of the partiesEducational gap between spouses.
  • Relative assets and liabilitiesIncluding court-ordered payments by either party.
  • Contribution to the other's education, training, or earning abilityIncluding contribution to a professional degree.
  • Time/expense to acquire education, training, or job experienceSo the requesting spouse can get appropriate employment.
  • Tax consequences of a support awardFor each party.
  • Lost income production capacityResulting from either party's marital responsibilities.
  • Any other relevant and equitable factorCatch-all under §3105.18(C)(1)(n).

Fault is not on this list. Marital misconduct is not a named §3105.18(C)(1) factor and could only enter through the general catch-all (n), if at all. How alimony is calculated →

How Ohio handles spousal support

Ohio courts call it "spousal support," and unlike Illinois or New York, the state legislature never wrote a calculation formula into law. Ohio Revised Code §3105.18 gives judges broad discretion, guided by an explicit list of factors rather than any percentage-based math. That makes any number produced by an online calculator for Ohio a non-statutory estimate by definition — useful for framing a conversation with an attorney, but not a stand-in for how a specific judge in a specific county will actually rule.

The governing factor list, verified directly against the official statute text at codes.ohio.gov, is Ohio Rev. Code §3105.18(C)(1)(a) through (n) — fourteen factors in total. They cover the income of the parties from all sources (including income from property divided in the case), the relative earning abilities of the parties, the ages and physical, mental, and emotional conditions of the parties, retirement benefits, the duration of the marriage, whether it would be inappropriate for a custodial parent to work outside the home given a minor child of the marriage, the standard of living established during the marriage, the relative extent of each party's education, the relative assets and liabilities of the parties (including court-ordered payments), the contribution of each party to the other's education, training, or earning ability — including contribution to a professional degree — the time and expense needed for the requesting spouse to acquire education, training, or job experience for appropriate employment, the tax consequences of a support award for each party, the lost income-production capacity of either party resulting from marital responsibilities, and a final catch-all for any other factor the court expressly finds relevant and equitable.

On fault, the statute is notably silent. After reading the complete official §3105.18(C)(1) text, none of the fourteen enumerated factors mentions adultery, marital misconduct, or fault of any kind. Every factor is financial, needs-based, or equity-based — income, earning ability, age and health, retirement benefits, marriage length, custodial-parent employment impact, standard of living, education, assets and liabilities, contributions to the other spouse's earning ability, time and expense to become employable, tax consequences, and lost income capacity, plus the general equity catch-all in factor (n). A court could theoretically weigh misconduct under that catch-all provision, but fault is not a named, mandatory consideration the way it is under Texas, Pennsylvania, or Michigan law — and it is explicitly not the kind of automatic bar seen in Georgia or North Carolina.

No major legislative overhaul of Ohio's spousal-support framework was identified for the 2023–2026 period; §3105.18 remains stable heading into 2026 proceedings. Statute citation: Ohio Rev. Code §3105.18.

Frequently Asked Questions

Does adultery affect alimony in Ohio?

Fault is not one of the 14 enumerated factors in §3105.18(C)(1). All 14 factors are financial, needs-based, or equity-based. A court could theoretically consider misconduct only under the general catch-all factor (n), but it is not a named or mandatory factor the way it is in some other states.

Is there a minimum marriage length to get spousal support in Ohio?

No minimum marriage-length threshold was identified in Ohio law. Marriage duration is one of the 14 §3105.18(C)(1) factors, but it is not a gate on eligibility itself.

Is this Ohio alimony calculator legal advice?

No. It's a non-statutory educational estimate. Ohio judges have broad discretion under §3105.18, and only a licensed Ohio family-law attorney can tell you what an actual court is likely to order in your case.
