How a Pension’s Marital Share Is Calculated: The Coverture Fraction in Ohio
Ohio names the retirement benefits of the spouses acquired during the marriage as marital property and divides marital property equally unless that would be inequitable. The statute sets no formula, so a time-rule fraction only illustrates the marital part.
What does Ohio say about dividing a pension?
Marital property means all real and personal property currently owned by either or both spouses, including the retirement benefits of the spouses, that was acquired during the marriage, and all interest in such property, and it excludes separate property (ORC 3105.171(A)(3)). In a divorce the court shall determine what is marital and what is separate property and divide marital property equitably (3105.171(B)).
Is the division equal in Ohio?
Yes, as the starting point: the division of marital property shall be equal, and only if an equal division would be inequitable does the court divide it in the manner it determines equitable, considering all relevant factors; each spouse is considered to have contributed equally to marital property (3105.171(C)(1)-(2)).
What factors can change the division in Ohio?
The duration of the marriage; the assets and liabilities of the spouses; the desirability of awarding the family home to the spouse with custody of the children; the liquidity of the property; the economic desirability of keeping an asset intact; tax consequences; costs of sale; any division in a voluntary separation agreement; any retirement benefits of the spouses, excluding social security except as relevant to dividing a public pension; and any other factor the court finds relevant (3105.171(F)).
What is a coverture fraction in Ohio?
It is a common way to find the marital part of a defined-benefit pension: months of service earned during the marriage divided by total months of service, applied to the benefit. Ohio’s statute does not prescribe it; we use it for illustration only, and the share is your own assumption in the Ohio pension division calculator.
How does the calculation work in a worked example in Ohio?
As an example, suppose a pension of $3,000 a month with 300 months of service, of which 180 months were during the marriage. The marital fraction is 60%, so the marital part is $1,800 a month. At a 50% share, the other spouse’s illustrative share is $900 a month and the plan holder keeps $2,100.
| Example figure | Value |
|---|---|
| Service during the marriage | 180 months |
| Total service | 300 months |
| Marital fraction | 60% |
| Marital part of the benefit | $1,800 |
| Illustrative share at 50% | $900 |
| Plan holder keeps | $2,100 |
This is a labeled example, not a prediction; a court may pick a different share, method or dates.
How is a pension actually paid to the other spouse in Ohio?
Usually through a domestic relations order that the plan accepts. A qualified domestic relations order creates or recognizes an alternate payee’s right to benefits and must meet federal requirements (26 U.S.C. 414(p); 29 U.S.C. 1056(d)(3)). A public deferred compensation account cannot be divided or paid out inconsistently with its governing law or rules, or before the account holder starts receiving it (3105.171(C)(4)).
Does fault matter for the pension in Ohio?
Only financial misconduct: dissipation, destruction, concealment, nondisclosure or fraudulent disposition of assets can lead to a distributive award or a greater award of marital property (3105.171(E)(4)). See the Ohio alimony calculator and the Ohio property division calculator.
