New Hampshire calculates child support using statutory guidelines under RSA 458-C. The formula is based on both parents' combined net income multiplied by a percentage that varies depending on income level and the number of children. Each parent's share is proportional to their respective income. The court may adjust the guideline amount based on special circumstances such as extraordinary medical expenses or approximately equal parenting schedules.

New Hampshire law recognizes three distinct types of alimony: temporary alimony during divorce proceedings, term alimony for post-divorce support with a statutory 23% income formula and 50% duration cap, and reimbursement alimony capped at 5 years to compensate contributions to a spouse's career. Under RSA 458:19 and RSA 458:19-a, New Hampshire courts calculate term alimony as the lesser of the payee's reasonable need or 23% of the gross income difference between spouses. For a 20-year marriage where one spouse earns $150,000 and the other earns $50,000, maximum term alimony would be $23,000 annually (23% of $100,000 difference) for up to 10 years (50% of marriage length). This guide covers all types of alimony in New Hampshire, calculation formulas, duration limits, modification rules, and termination events for 2026.

Understanding Types of Alimony in New Hampshire

New Hampshire courts may award three distinct types of alimony under state law: temporary alimony during proceedings, term alimony for post-divorce support calculated at 23% of the income differential with a duration cap of 50% of the marriage length, and reimbursement alimony capped at 5 years to compensate economic or non-economic contributions to the payor's career. Unlike some states that recognize permanent or bridge-the-gap alimony, New Hampshire's 2018 alimony reform (effective January 1, 2019) eliminated traditional open-ended spousal support in favor of predictable formulas and duration limits. The statutory framework under RSA 458:19, RSA 458:19-a, and RSA 458:19-aa provides specific calculation methods that apply to all divorces filed on or after January 1, 2019.

The types of alimony in New Hampshire differ significantly from neighboring states. Massachusetts uses durational categories based on marriage length, while Vermont grants broader judicial discretion. New Hampshire's formula-based approach provides greater predictability, with courts using the 23% income differential calculation as the default starting point for term alimony orders.

Temporary Alimony in New Hampshire

Temporary alimony provides financial support during divorce proceedings and automatically terminates upon entry of the final divorce decree, typically lasting 3 to 12 months depending on case complexity. Under RSA 458:19, temporary alimony serves to maintain the status quo during litigation, ensuring the lower-earning spouse can meet basic expenses while the divorce is pending. Courts may order temporary alimony at the initial hearing, often within 30-60 days of filing, without the detailed analysis required for permanent orders. The amount is based on immediate need rather than the statutory 23% formula that applies to term alimony.

Temporary alimony addresses urgent financial disparities during the divorce process. A spouse who was financially dependent during the marriage may otherwise struggle to pay for housing, utilities, health insurance, and legal representation while the case proceeds. New Hampshire courts recognize this practical need and routinely award temporary support when significant income disparities exist between spouses.

The following circumstances commonly justify temporary alimony awards in New Hampshire:

  • Income disparity exceeding $30,000 annually between spouses
  • One spouse controlling majority of liquid assets during separation
  • Dependent spouse lacking employment or earning capacity
  • Need to maintain marital residence pending property division
  • Health insurance coverage requirements during proceedings

Term Alimony: New Hampshire's Primary Post-Divorce Support

Term alimony is New Hampshire's primary form of post-divorce spousal support, calculated as 23% of the gross income difference between spouses with a maximum duration of 50% of the marriage length under RSA 458:19-a. For a marriage lasting 16 years where the higher-earning spouse has gross income of $180,000 and the lower-earning spouse earns $60,000, the formula produces maximum annual alimony of $27,600 (23% of $120,000) for up to 8 years (50% of 16 years). The court awards the lesser of this formula amount or the payee's demonstrated reasonable need.

The 23% calculation percentage specifically reflects the 2017 federal tax law change that eliminated alimony deductibility for payors. Previously, when alimony was tax-deductible to the payor and taxable to the payee, New Hampshire used a 30% formula. If federal tax law changes to restore deductibility, the statute automatically reverts to 30% of the income differential.

Term Alimony Calculation Example

FactorHigher EarnerLower Earner
Gross Annual Income$200,000$60,000
Income Differential$140,000--
Formula Amount (23%)--$32,200/year
Monthly Payment--$2,683/month
Marriage Length20 years20 years
Maximum Duration--10 years

Courts may adjust the 23% formula when justice requires deviation based on special circumstances. RSA 458:19-a identifies specific factors that may justify adjustments: health conditions including disability or chronic illness, the degree and duration of financial dependency, vocational skills and employability, voluntary unemployment or underemployment by either party, the special needs of minor or adult children, and property awarded under the equitable distribution statute. The party seeking an adjustment bears the burden of proving why deviation from the formula is warranted.

Income Adjustments for Term Alimony

New Hampshire law requires specific adjustments to gross income before applying the 23% formula. The payor's gross income is reduced by amounts actually paid for child support, existing alimony obligations, and costs for health insurance coverage benefiting the other party. The payee's income calculation adds back child support received for the parties' joint children. These adjustments ensure the alimony calculation accounts for other support obligations and benefits flowing between the parties.

Reimbursement Alimony: Compensating Career Contributions

Reimbursement alimony compensates a spouse for economic or non-economic contributions to the other's financial resources, capped at 5 years maximum duration and not subject to modification except by agreement under RSA 458:19-a. This alimony type applies when one spouse supported the other through education, professional training, or career development and the marital property available for division is either inappropriate or inadequate to provide fair compensation. Common examples include financing a spouse's medical school, law school, or MBA program while forgoing one's own career advancement.

The court must make a finding that reimbursement alimony is equitable before issuing an order. Unlike term alimony, reimbursement alimony cannot be modified after entry except by mutual agreement of the parties. This non-modifiable nature reflects the compensatory purpose of this alimony type, which addresses a specific contribution rather than ongoing support needs.

Reimbursement alimony is appropriate in the following circumstances:

  • Supporting spouse through graduate or professional education
  • Sacrificing career opportunities for spouse's employment transfers
  • Making substantial economic contributions to spouse's business
  • Providing non-economic contributions enabling spouse's career advancement
  • Property division inadequate to compensate these contributions

How New Hampshire Differs From Other Alimony Types

New Hampshire does not recognize permanent alimony, bridge-the-gap alimony, or durational alimony as separate categories, instead consolidating post-divorce support into the term and reimbursement framework established by the 2018 reforms. States like Florida recognize five distinct alimony types including permanent, bridge-the-gap, rehabilitative, durational, and lump-sum alimony. Massachusetts uses durational categories tied to marriage length. New Hampshire's streamlined approach with its 23% formula and 50% duration cap provides greater predictability but less judicial flexibility compared to these neighboring jurisdictions.

The absence of permanent alimony in New Hampshire represents a significant policy shift from the state's prior law. Before the 2018 reforms, courts could award open-ended alimony without statutory duration limits. The current law caps even the longest-term alimony awards at 50% of the marriage length, meaning a 30-year marriage produces a maximum 15-year term alimony obligation.

Factors Courts Consider When Awarding Alimony

New Hampshire courts analyze 15 statutory factors under RSA 458:19 when determining whether to award alimony, including length of marriage, age and health of parties, occupation and employability, sources of income, property awarded in divorce, and the standard of living established during marriage. The statute does not assign specific weights to these factors, allowing courts discretion to emphasize different considerations based on the circumstances of each case. Courts must provide written findings explaining the basis for alimony awards.

The following factors carry particular weight in New Hampshire alimony determinations:

  • Length of marriage (longer marriages favor larger and longer awards)
  • Age, health, and emotional condition of each party
  • Occupation, vocational skills, and employability of each party
  • Amount and sources of income for each party
  • Property awarded under equitable distribution
  • Standard of living established during the marriage
  • Present and future ability to be self-supporting
  • Contributions to the other's education or earning capacity
  • Any other factor the court deems relevant

Duration Limits and the 50% Rule

Term alimony in New Hampshire cannot exceed 50% of the marriage length under the statutory framework, meaning a 10-year marriage produces a maximum 5-year alimony obligation while a 24-year marriage produces a maximum 12-year obligation. This duration cap applies unless the parties agree otherwise in a settlement agreement or the court finds that justice requires adjustment based on the special circumstances enumerated in RSA 458:19-a. Courts may use different beginning or ending dates when measuring marriage length if justice requires.

The 50% duration rule creates predictable expectations for both payors and payees. A spouse leaving a 20-year marriage knows that term alimony cannot extend beyond 10 years absent extraordinary circumstances or mutual agreement. This predictability facilitates settlement negotiations and financial planning during the divorce transition.

Measuring Marriage Length

New Hampshire courts typically measure marriage length from the date of marriage to the date of final separation or divorce filing. However, RSA 458:19-a permits courts to use different beginning or ending dates when justice requires. Premarital cohabitation may be considered as a factor supporting deviation from the equal property division presumption under RSA 458:16-a, and similar considerations may apply to alimony duration determinations in appropriate cases.

Modification of Alimony in New Hampshire

New Hampshire permits alimony modification upon showing a substantial and unforeseeable change in circumstances, proven by clear and convincing evidence under RSA 458:19-aa, with common grounds including job loss, disability, significant income changes, and the payee's cohabitation. The clear and convincing evidence standard is higher than the preponderance standard used in most civil matters, reflecting the legislature's intent to provide stability in alimony orders while allowing relief for genuine changed circumstances.

Modification requires more than minor fluctuations in income or circumstances. A temporary job loss followed by comparable reemployment would typically not justify modification. However, permanent disability, involuntary termination followed by extended unemployment, or a dramatic change in either party's financial circumstances may warrant court review.

Reimbursement alimony differs from term alimony in that it cannot be modified except by agreement of the parties. This non-modifiable characteristic reflects the compensatory nature of reimbursement alimony, which addresses a specific contribution rather than ongoing support needs that may change over time.

Termination of Alimony in New Hampshire

Alimony automatically terminates in New Hampshire when the recipient remarries, when the recipient cohabitates in a marriage-like relationship with an unrelated adult, or when the payor reaches Social Security full retirement age (currently 66-67 depending on birth year) under RSA 458:19-aa. These automatic termination provisions operate without requiring court action, although the payor may need to file a motion to formally terminate the order and stop wage withholding if applicable.

Cohabitation termination requires proof that the payee is living with another person in a relationship resembling marriage. Courts consider the following factors when determining whether cohabitation exists: living together on a continual basis in a primary residence, sharing expenses, economic interdependence, joint ownership or use of property including financial accounts, the existence of an intimate relationship, holding themselves out as a couple, and any other material factors.

Reinstatement After Termination

New Hampshire uniquely allows reinstatement of alimony terminated due to cohabitation or remarriage under RSA 458:19-aa. If the payee's cohabitation relationship ends or subsequent marriage ends in divorce, the payee may request reinstatement within 5 years of the termination order's effective date. If the original alimony order had a specific end date, reinstatement cannot extend beyond that date. This provision recognizes that cohabitation relationships and subsequent marriages may fail, leaving the payee in the same position of need that originally justified alimony.

Filing for Alimony: Procedural Requirements

New Hampshire divorce filing fees are $250 without minor children and $282 with minor children as of March 2026, plus potential additional costs for motions ($85 each) and modification petitions ($135-$225). All credit and debit card payments incur an additional 3% processing surcharge. Alimony requests are typically included in the divorce petition or raised in the respondent's answer. The court addresses alimony at temporary hearings for immediate needs and at final hearing for permanent orders.

New Hampshire's residency requirements provide three pathways for filing: both spouses domiciled in New Hampshire with no durational requirement, the filing spouse domiciled in New Hampshire with service possible within state borders, or the filing spouse domiciled in New Hampshire for one year or more before filing. Domicile requires living in New Hampshire with the intention to remain permanently or indefinitely.

Divorce is filed in the Circuit Court, Family Division, in the county where either spouse resides. All New Hampshire counties have Family Division courts handling divorce and alimony matters.

Tax Implications of Alimony

Under current federal tax law effective for divorces finalized after December 31, 2018, alimony is neither deductible to the payor nor taxable income to the payee, which is why New Hampshire uses the 23% formula rather than the previous 30% calculation. The 2017 Tax Cuts and Jobs Act eliminated alimony deductibility for agreements executed after 2018. New Hampshire's statute automatically adjusts to 30% if federal tax law restores deductibility, ensuring the formula accounts for the actual after-tax impact on both parties.

This tax treatment represents a significant change from prior law. Before 2019, payors could deduct alimony payments from taxable income while payees reported alimony as taxable income. The current non-deductible status means payors pay alimony from after-tax dollars, which the 23% formula (lower than the previous 30%) is designed to address.

Alimony and Property Division Relationship

New Hampshire courts consider alimony and property division together under RSA 458:16-a, with the property settlement presumptively equal (50/50) and alimony addressing ongoing income disparities that property division cannot adequately remedy. A spouse receiving a larger property share may receive less alimony, while a spouse receiving minimal property might receive enhanced alimony to compensate. The interplay between these two forms of economic relief requires holistic analysis of the parties' financial circumstances.

New Hampshire's all-property approach to equitable distribution means courts can divide any asset owned by either spouse regardless of when or how acquired. This broad divisibility includes premarital property, inherited assets, and gifts, although the source and timing of acquisition are factors courts may consider when determining whether equal division is equitable. The relationship between property division and alimony becomes particularly significant when substantial assets exist that could provide the lower-earning spouse with income-producing investments rather than ongoing support payments.
