North Dakota Maintenance Case Law

Walden v. Walden (2025)
2025 ND 32, Docket No.: 20240131

The North Dakota Supreme Court affirmed a spousal support award in a case involving domestic violence and a short-term marriage. The Court reiterated that district courts must consider the Ruff-Fischer guidelines, the needs of the spouse seeking support, and the ability of the other spouse to pay when determining whether to award spousal support. The Court also noted that a party who fails to provide evidence of net income waives any argument that they lacked the ability to pay.

P.O. v. J.O. (2024)
2024 ND 187, Docket No.: 20230295

The North Dakota Supreme Court clarified that under NDCC 14-05-24.1, the statutory caps on duration are rebuttable presumptions. The Court held that a district court may deviate from the presumptive maximum duration if it makes specific written findings justifying the deviation, such as a recipient's disability or inability to become self-sufficient despite good-faith efforts.

Riehl v. Riehl (2002)
652 N.W.2d 791 (N.D. 2002)

The Supreme Court upheld an award of maintenance to a spouse who had supported her husband through medical school. The court ruled that the trial court properly considered the spouse's contributions to the husband's medical education and the standard of living established during the marriage.

Modifying Maintenance in North Dakota

Under N.D.C.C. § 14-05-24.1, maintenance can be modified upon a showing of a substantial and continuing change in circumstances.

1. Legal Standards for Modification
Substantial and Continuing Change Required: The change must be material and ongoing — temporary fluctuations are insufficient.
Automatic Termination on Remarriage: Unless otherwise agreed in writing, support is terminated by law upon the remarriage of the recipient spouse.
One-Year Cohabitation Standard: Support also terminates by law upon a court order finding the recipient has been habitually cohabiting with another person in a relationship analogous to marriage for one year or more — this does not apply to rehabilitative support.
Duration Caps Are Rebuttable Presumptions: The statutory caps on duration under NDCC 14-05-24.1 are rebuttable — a district court may deviate from the presumptive maximum duration with specific written findings, such as a recipient's disability or inability to become self-sufficient despite good-faith efforts (P.O. v. J.O., 2024).
Retirement Creates a Rebuttable Presumption: Payor's retirement at full Social Security age creates a rebuttable presumption favoring termination.
2. Common Grounds for Modification
Recipient's Remarriage: Automatic termination by law; payor should still file to formally close out the order.
Habitual Cohabitation for One Year or More: In a relationship analogous to marriage.
Payor's Retirement at Full Social Security Age: A rebuttable presumption for termination.
Recipient's Improved Earning Capacity: May justify reduction or termination.
Documented Disability or Inability to Become Self-Sufficient: May justify an extension beyond the presumptive duration cap despite good-faith efforts (P.O. v. J.O.).
3. Step-by-Step Modification Process
Step 1 – Gather Evidence: Tax returns, pay stubs, medical records, proof of cohabitation duration and nature of the relationship.
Step 2 – File a Petition for Modification: Submit to the court that issued the original order.
Step 3 – Serve Notice: Legally notify the other party using certified mail or a process server.
Step 4 – Mediation: Many North Dakota courts require mediation before a hearing.
Step 5 – Court Hearing: If unresolved, present evidence to the court; a party who fails to provide evidence of net income waives any argument that they lacked the ability to pay (Walden v. Walden, 2025).
Step 6 – Order on Modification: Modifications are not retroactive — they only apply from the filing date forward.
4. Critical Practical Considerations
Never stop paying without a new court order: Doing so risks contempt and arrears accumulation.
No retroactive modification: Act promptly when circumstances change, since relief runs only from the filing date.
Document the full year for cohabitation claims: The one-year habitual cohabitation threshold must be established, and does not apply if support was rehabilitative.
Prepare evidence of net income: Under Walden v. Walden, failing to submit net income evidence at the hearing waives the ability-to-pay argument entirely.

North Dakota Spousal Maintenance FAQs

North Dakota law establishes rebuttable presumptive maximum durations based on marriage length:

  • Under 5 years: Up to 50% of the marriage length
  • 5-10 years: Up to 60% of the marriage length
  • 10-15 years: Up to 70% of the marriage length
  • 15-20 years: Up to 80% of the marriage length
  • 20+ years: No statutory cap, but permanent alimony is banned. Maximum generally 10-15 years unless exceptional circumstances.

Courts may deviate with written findings justifying the deviation.

North Dakota Century Code NDCC 14-05-24.1 (as amended)

North Dakota now recognizes:

  • Rehabilitative Spousal Support: For education/training to become self-supporting.
  • General Term Spousal Support: Limited-duration support when a spouse cannot become fully self-supporting due to age, health, etc.
  • Lump Sum Spousal Support: A one-time payment instead of monthly support.

Note: "Permanent" spousal support has been eliminated by law. Even in 20+ year marriages, support is for a defined term.

Courts cannot award maintenance unless both conditions are met:

  • The recipient lacks sufficient property to meet reasonable needs, AND
  • The payor has the ability to pay without incurring undue economic hardship.

If the payor cannot afford the calculated support plus their own basic living expenses, the court must reduce or deny support entirely.

NDCC 14-05-24.1(1)

Unless otherwise agreed in writing, spousal support terminates by law upon:

  • Remarriage of the spouse receiving support.
  • A court order finding the recipient has been in a habitual cohabitation relationship for one year or more.

There is also a rebuttable presumption that support terminates when the payor reaches full Social Security retirement age.

North Dakota is a no-fault divorce state:

  • Fault generally doesn't affect maintenance decisions
  • Extreme misconduct may be considered in rare cases
  • Economic misconduct (hiding assets) may affect awards

North Dakota Century Code NDCC 14-05-24.1

Federal tax (2025-2026): Under the Tax Cuts and Jobs Act of 2017, maintenance payments are no longer deductible for the payor or taxable to the recipient for divorce agreements executed after December 31, 2018.

North Dakota tax: Follows federal treatment — no deduction for payor or income for recipient for post-2018 agreements.

IRC § 71, Tax Cuts and Jobs Act of 2017

Retirement impacts North Dakota maintenance cases:

  • Payor may petition to modify/terminate at retirement age
