New Hampshire Maintenance Case Law Examples

In the Matter of Bondaz & Bondaz (2025)
NH Supreme Court No. 2024-0327

Landmark ruling: The court held that a spouse's "reasonable need" is the legal maximum for alimony, not the 23% formula. The formula merely establishes a ceiling; courts must not award more than needed to cover reasonable expenses after accounting for recipient's own income and assets. This calculator now strictly caps the award by need.

In the Matter of Hoyt & Hoyt (2018)
171 N.H. 373

Key precedent for 2025 child support guidelines: Courts cannot order parents to share expenses outside of support order without agreement. Affects ability-to-pay analysis for alimony when child support is presumed $0 under 2025 rules.

In the Matter of Letourneau & Letourneau (2008)
154 N.H. 1

Held that a payor's voluntary retirement may constitute a change in circumstances warranting modification of alimony, but the court will examine whether the retirement was reasonable under the circumstances. Payer's age factor included in duration adjustments.

In the Matter of Watterworth & Watterworth (2011)
161 N.H. 175

Affirmed that the primary purpose of alimony is to help the recipient become self-supporting while maintaining the standard of living established during the marriage to the extent possible — now limited by the Bondaz reasonable-need ceiling.

Modifying Maintenance in New Hampshire

New Hampshire law allows for modification of maintenance under certain circumstances. Here's the process for requesting a modification:

Grounds for Modification

Maintenance can be modified for:

A substantial and continuing change in circumstances
Remarriage of the recipient spouse
Payor's retirement at a reasonable age
Recipient's improved earning capacity
Disability or health issues affecting earning capacity

Modification Process

File a Petition: Submit a Petition for Modification to the court that issued the original order.
Serve Notice: Legally notify the other party using certified mail or a process server.
Gather Evidence: Collect documentation supporting the change (tax returns, pay stubs, medical records).
Mediation: Many New Hampshire courts require mediation before a hearing.
Court Hearing: If unresolved, present evidence to the court for a decision.

Important Considerations

Modifications are not retroactive - they only apply from the filing date forward.
Never stop paying maintenance without court approval - you risk contempt charges.
New Hampshire requires a "substantial and continuing" change in circumstances.
Retirement modifications typically require the payer to be at least 65 years old.

Note: The modification process typically takes 3-6 months for uncontested cases and 9-18 months for contested cases, depending on court backlogs.

New Hampshire Spousal Maintenance FAQs

What changed in alimony calculation after Bondaz?

The NH Supreme Court ruled that the 23% statutory formula (RSA 458:19-a) is only a ceiling. The final award is capped by the recipient's reasonable need (housing + health + essentials minus their own income). Our calculator now calculates: Math.min(23% of income gap, reasonable need). If need is lower, that controls.

Does the 2025 child support change affect alimony?

Yes. For equal parenting, similar incomes, and shared expenses, there's a rebuttable presumption of $0 child support. This increases payor's available income for alimony, which the calculator accounts for in the ability-to-pay check.

What are HB 1036 and HB 1757 (pending 2027)?

HB 1036 would impose an 8-year absolute cap on alimony duration. HB 1757 would bar alimony entirely for marriages of 6 years or less. Our "Apply Pending 2027 Rules" toggle lets you see the potential impact.

Is alimony taxable in NH?

Under federal TCJA (post-2018), alimony is not deductible for payor nor taxable to recipient. NH has no state income tax, so no state tax impact.

How does retirement affect alimony after Bondaz?

Payor's retirement at 65+ is grounds for modification. The court will re-evaluate payor's ability to pay and recipient's need. Our calculator reduces support by 20% if payor age ≥65 as a general estimate.

How does marriage length affect maintenance in New Hampshire?

Marriage duration significantly impacts New Hampshire maintenance: Under 5 years: Typically no maintenance unless exceptional circumstances; 5-10 years: Maintenance for 20-40% of marriage duration; 10-20 years: Maintenance for 40-60% of marriage duration; 20+ years: May receive maintenance for longer periods or permanently. Special considerations for disabled spouse or career sacrifices may extend duration.

Can maintenance be modified or terminated in New Hampshire?

Yes, under certain conditions: Automatic Termination: When recipient remarries; Modification: For substantial and continuing change in circumstances; Termination: At end of ordered period or upon court order. Grounds for modification include significant income change, payor's retirement, recipient's improved earning capacity, disability, or cohabitation.
