Spousal support in Ohio is determined by a statutory multi-factor analysis under O.R.C. § 3105.18. The court weighs the following factors to arrive at a fair support amount and duration. Unlike the temporary formula, there is no mathematical calculation for permanent support — it is a discretionary determination by the judge based on the totality of the circumstances.
The types of spousal support available in Ohio include: Temporary, Fixed-term, Indefinite, Lump-sum, In-kind. The type ordered depends on the length of the marriage, each spouse's financial situation, and the supported spouse's ability to become self-supporting.
Primary statute: O.R.C. § 3105.18
The court considers these 12 statutory factors when determining the amount and duration of spousal support:
Income and earning ability of each party
Relative ages of the parties
Duration of the marriage
Standard of living established during the marriage
Physical, emotional, and mental conditions of each party
Retirement benefits of each party
Education of each party
Contributions as a homemaker
Tax consequences
Lost income from homemaking
Result of the property division
Any other factor the court deems relevant and equitable
No formula. Entirely discretionary. Common judicial estimate: 25–33% of net income difference (NOT a statute).
Duration is one of the most heavily litigated aspects of spousal support. The length of the marriage is the single most important factor in most cases, but the court also considers the supported spouse's age, health, job skills, and the time needed to acquire education or training for appropriate employment.
CRITICAL: Modifiability clause requirement (§3105.18(E)(1)) — without explicit language in the decree retaining jurisdiction, the court has NO authority to modify support later.
Property division must be completed FIRST; spousal support analyzed separately.
Ohio uses "spousal support" terminology, not "alimony."
