    Spousal Support in New Hampshire

    New Hampshire's alimony law sorts support into named categories. It does not treat alimony as one single award. The relevant law is RSA 458:19 and RSA 458:19-a. The statute defines temporary alimony, which covers a case while it is pending. It also defines term alimony, periodic payments made after the divorce decree becomes final. A third category, reimbursement alimony, compensates a spouse for economic or non-economic contributions made during the marriage. A common example is funding the other spouse's education. To qualify for term alimony, the requesting spouse must prove three things. First, financial need. Second, an inability to become self-supporting through appropriate employment, or a valid reason tied to parenting responsibilities. Third, that the other spouse can meet their own needs while still paying support. New Hampshire also caps how long term alimony can run, based on the length of the marriage. That kind of cap is not universal among states. It gives New Hampshire filers a clearer starting point for estimating duration than the pure discretion many other states use.

    Eligibility for term alimony

    Under RSA 458:19-a, a court may order term alimony if the requesting spouse proves three things. First, the spouse lacks sufficient income, property, or both, to meet their own reasonable needs. Second, the spouse cannot become self-supporting through appropriate employment, or has primary parental responsibilities that justify limiting outside work. Third, the other spouse can meet their own reasonable needs while also paying support. All three parts must be shown.

    This three-part structure means New Hampshire courts look closely at both spouses' finances at once, instead of focusing only on what the requesting spouse needs.

    Duration: capped at half the length of the marriage

    New Hampshire limits the default length of term alimony. The cap is 50% of the length of the marriage. Two exceptions apply. The parties can agree to something different. Or the court can find that justice requires an adjustment. This built-in cap is more concrete than the duration rules many states use. Still, the court keeps discretion to depart from it, for good reason stated on the record.

    Factors that can adjust the amount

    Beyond the basic eligibility test, New Hampshire courts can adjust the amount of alimony. They look at special circumstances, including a party's health or disability, and how long the requesting spouse has been financially dependent. They also consider employment skills and employability, and voluntary unemployment or underemployment. Other factors are a child's special needs, marital misconduct or abuse, and differences in expected Social Security benefits. Courts also weigh diminution of assets and the tax consequences of the award.

    Reimbursement alimony and termination

    Reimbursement alimony works differently from term alimony. It compensates a spouse for contributions made to the other spouse's earning capacity, career, or education during the marriage. This kind of alimony is capped at a maximum of five years. It generally cannot be modified except by agreement of the parties. Term alimony, by contrast, ends when the recipient remarries, unless the parties agreed otherwise.

    New Hampshire's statute also ties support to the difference between the parties' incomes, using a formula. The exact percentages in that formula, and how they interact with recent federal tax changes, aren't listed on this page. Check the statute or a New Hampshire family court self-help resource for the exact calculation before you rely on a specific number. A wrong figure could throw off an entire settlement discussion.

    Where New Hampshire alimony cases are filed

    Divorce cases in New Hampshire, including any request for alimony, are filed in the family division of the circuit court for the county where one spouse resides. Alimony, property division, and any parenting-related issues are generally decided together in the same case. New Hampshire's alimony statute distinguishes term, temporary, and reimbursement alimony very specifically. It helps to identify early which type fits your situation, since that affects both the eligibility test and the paperwork the court expects to see. The circuit court clerk's office can confirm current local forms and procedures.

    Spousal Support in New Hampshire: frequently asked questions

    What types of alimony does New Hampshire recognize?+

    New Hampshire recognizes three types of alimony under RSA 458:19. Temporary alimony is support paid while a divorce case is pending. Term alimony is periodic payments made after the decree is final. Reimbursement alimony compensates a spouse for contributions to the other spouse's education, training, or career during the marriage.

    How long can term alimony last in New Hampshire?+

    The default cap is 50% of the length of the marriage, unless the parties agree to a different duration or the court finds that justice requires an adjustment. This cap comes from RSA 458:19-a and is more specific than the open-ended duration rules many states use.

    Who qualifies for term alimony in New Hampshire?+

    A spouse must show three things. First, they lack sufficient income or property to meet their reasonable needs. Second, they cannot become self-supporting through appropriate employment, or they have primary parenting duties that justify limiting work. Third, the other spouse can pay support while still meeting their own needs.

    Does New Hampshire alimony end if the recipient remarries?+

    Term alimony ends when the recipient remarries, unless the parties agreed otherwise. Reimbursement alimony works on a different track. It compensates for past contributions rather than ongoing need, and it's capped at five years.

    Can reimbursement alimony be modified in New Hampshire?+

    Generally no. Reimbursement alimony is capped at a maximum of five years, and it cannot be modified except by agreement of the parties. Term alimony is different: it can be adjusted for changed circumstances.

    Is New Hampshire alimony taxable?+

    Under federal law, for agreements executed after December 31, 2018, alimony is not deductible by the paying spouse and not taxable to the recipient. This is a federal Tax Cuts and Jobs Act rule that applies the same way in New Hampshire as elsewhere.
