How a Pension’s Marital Share Is Calculated: The Coverture Fraction in New Hampshire
New Hampshire treats vested and non-vested pensions as property and presumes an equal division is equitable, with written reasons for any departure. The time-rule fraction only illustrates the marital part.
What does New Hampshire say about dividing a pension?
Property includes all tangible and intangible property and assets, real or personal, belonging to either or both parties, whether title is held in the name of either or both; intangible property includes employment benefits, vested and non-vested pension or other retirement benefits, and savings plans (RSA 458:16-a, I). When a dissolution is decreed the court may order an equitable division, and it presumes that an equal division is equitable unless it decides an equal division would not be appropriate or equitable after considering the listed factors (458:16-a, II).
What factors can overcome the equal division in New Hampshire?
The duration of the marriage; each party’s age, health, status, occupation, skills, employability, separate property, income, needs and liabilities; the opportunity for future acquisition of capital assets and income; the custodial parent’s ability to work and need for the marital residence; actions during the marriage that contributed to the growth or diminution of property; significant disparity in contributions, including to the children and the home; contributions to the other’s career and interruptions of career; the expectation of pension or retirement rights acquired before or during the marriage; tax consequences; a valid prenuptial contract; fault under RSA 458:7 that caused the breakdown and caused substantial pain or economic loss; premarital and gifted property; and any other relevant factor (458:16-a, II(a)-(o)).
What is a coverture fraction in New Hampshire?
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. New Hampshire’s statute does not prescribe it; we use it for illustration only, and the share is your own assumption in the New Hampshire pension division calculator.
How does the calculation work in a worked example in New Hampshire?
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 or method.
How is a pension actually paid to the other spouse in New Hampshire?
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.
Does fault matter for the pension in New Hampshire?
It can, in a limited way: fault under RSA 458:7 that caused the breakdown and caused substantial physical or mental pain and suffering or substantial economic loss is one factor that can overcome the equal division (458:16-a, II(l)). See the New Hampshire alimony calculator and the New Hampshire property division calculator.
