How a Pension’s Marital Share Is Calculated: The Coverture Fraction in Wisconsin

Wisconsin presumes equal division of property and names pension benefits, vested or unvested, among the economic circumstances the court weighs. The statute sets no pension formula, so a time fraction only illustrates the marital part.

What does Wisconsin say about dividing a pension?

On every judgment of divorce the court divides the property of the parties; it presumes all property that is not an excluded gift or inheritance is divided equally but may alter that, without regard to marital misconduct, after considering thirteen factors (Wis. Stat. 767.61(1), (3)). One factor is “other economic circumstances of each party, including pension benefits, vested or unvested, and future interests” (767.61(3)(j)).

Is the division equal in Wisconsin?

Presumptively. The factors that can move it are the length of the marriage, property brought to the marriage, substantial assets not subject to division, each party’s contribution including homemaking and child care, age and health, contribution to the other’s education or earning power, earning capacity, the family home for the parent with greater placement, the amount and duration of maintenance, other economic circumstances, tax consequences, any written agreement made before or during the marriage and other relevant factors (767.61(3)).

What is a coverture fraction in Wisconsin?

It is the proportion of a retirement benefit attributable to the marriage: months of service earned during the marriage divided by total months of service, applied to the benefit. Wisconsin’s statute does not prescribe it; it is an illustration in the Wisconsin pension division calculator, and the share is your own assumption.

How does the calculation work in a worked example in Wisconsin?

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.

This is a labeled example, not a prediction; the court sets the share and the method.

How is a pension actually paid to the other spouse in Wisconsin?

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)). Government plans have their own order rules, so ask the plan before the decree is drafted. The judgment itself must notify the parties that more steps may be needed to transfer retirement interests (767.61(5)(b)).

Can a spouse waive the pension share in Wisconsin?

Yes, by a written agreement the court approves, and the order should say so clearly so the plan does not pay the other spouse (767.61(3)(L); 767.34).

Does fault matter for the pension in Wisconsin?

No. The presumption is altered “without regard to marital misconduct” (767.61(3)). See the Wisconsin alimony calculator and the Wisconsin property division calculator.

Do agreements change this in Wisconsin?

A written agreement made before or during the marriage is binding on the court unless its terms are inequitable as to either party, and the court presumes it equitable (767.61(3)(L)); spouses may also stipulate to a property division subject to approval (767.34).
