North Dakota Spousal Support (Alimony) Laws: No Permanent Support (2026)

North Dakota calls it spousal support, not alimony. Under N.D.C.C. 14-05-24.1, a court may not award permanent spousal support. Every award must be for a limited, definite period, and courts apply the Ruff-Fischer case-law factors to set the amount and duration.

What Is Spousal Support in North Dakota?

North Dakota uses the term spousal support rather than alimony. The two terms describe the same concept: a court-ordered payment from one spouse to the other after divorce or separation. The governing statute is N.D.C.C. 14-05-24.1, which was amended in 2015 and again significantly in 2023 (HB 1037, effective August 1, 2023).

A court may award spousal support only after making two express findings: (1) the recipient lacks sufficient property or income to provide for their reasonable needs considering the marital standard of living, and (2) the paying spouse has the ability to supply support without undue economic hardship. Without both findings, no award is authorized.

Spousal support in North Dakota is not automatic. It is not awarded in every divorce, and the statute does not presume that either spouse is entitled to it. Each case turns on its own financial record and the weighing of the Ruff-Fischer factors discussed below.

North Dakota Bars Permanent Spousal Support

The most distinctive feature of North Dakota's spousal support law is the statutory prohibition on permanent awards. N.D.C.C. 14-05-24.1 states that the court may require one party to pay spousal support "for a limited period of time." The phrase "a limited period of time" is mandatory. A court cannot issue an open-ended order with no termination date.

This was not always the law. North Dakota spousal support law has been amended twice in recent years. In 2015, the legislature added the remarriage and cohabitation termination provisions. In 2023, House Bill 1037 (effective August 1, 2023) added the explicit prohibition on permanent support, the statutory definitions of each support type, and the duration percentage guidelines. Every non-rehabilitative spousal support order must include a specific end date.

The statute also provides guidance on how to set that duration. For marriages under five years, support may run for up to 50 percent of the length of the marriage. For marriages of five to ten years, the cap is up to 60 percent of the marriage length. For marriages of ten to fifteen years, up to 70 percent. For marriages of fifteen to twenty years, up to 80 percent. For marriages over twenty years, the court sets an appropriate limited duration based on the circumstances. These ranges are guideposts, not mandatory floors, and the judge retains discretion to award a shorter term within any range.

Note that rehabilitative spousal support operates somewhat differently. The statute's termination provisions for remarriage and cohabitation do not apply to rehabilitative awards. Rehabilitative support runs for the period the court determines is reasonably needed to allow the recipient to acquire education or job skills.

How Courts Decide Support: The Ruff-Fischer Guideline Factors

North Dakota has no formula or worksheet for calculating the amount of spousal support. The court exercises broad discretion guided by the Ruff-Fischer guidelines, a set of factors derived from case law and consistently applied by the North Dakota Supreme Court.

The Ruff-Fischer factors are:

1. The respective ages of the parties
2. Each party's earning ability
3. The duration of the marriage and the conduct of the parties during the marriage
4. The station in life of the parties
5. The circumstances and necessities of each party
6. The health and physical condition of each party
7. The financial circumstances of each party, including property owned at the time of divorce, its value, its income-producing capacity, and whether it was accumulated before or after the marriage
8. Any other matter the court finds to be material

No single factor is controlling. The judge weighs all eight factors together in light of the full evidentiary record. The court is not required to make a specific finding on each factor, but it must articulate a rationale for its decision, which creates a record for any appeal.

Marital fault can play a role because the conduct of the parties during the marriage is one of the listed factors. North Dakota is among the minority of states that permits a judge to consider misconduct, including adultery, abuse, or financial waste, when deciding whether to award support and in what amount.

Property division is closely connected. Spousal support and equitable distribution of marital property are interrelated. A court must consider how the property settlement affects each party's financial position before setting a support amount. A spouse who receives substantial property in the divorce may be awarded little or no spousal support, while a spouse who receives little property may receive a larger or longer award.

Types of Spousal Support

North Dakota recognizes three forms of spousal support under N.D.C.C. 14-05-24.1.

Rehabilitative spousal support is the most commonly awarded type. Its purpose is to give the recipient spouse a realistic opportunity to acquire education, vocational training, work experience, or job skills that will allow that spouse to reach economic self-sufficiency. The duration is set to match the time reasonably needed to complete the educational or training goal. Rehabilitative support is not subject to automatic termination upon remarriage or cohabitation under the statute's termination provisions.

General term spousal support is available when the court finds that rehabilitation to independent economic status is not possible. This type is reserved for cases where the recipient spouse cannot reasonably be expected to become self-supporting, such as a spouse with a serious long-term disability or a spouse of advanced age after a very long marriage. Because permanent support is prohibited by statute, general term support must still carry a defined end date.

Lump sum spousal support may be awarded as additional marital property. It is a one-time payment rather than a series of periodic payments. Once paid, it cannot be modified.

When Support Ends or Changes

N.D.C.C. 14-05-24.1 specifies several events that affect a spousal support order.

Automatic termination. Unless the parties' written agreement provides otherwise, spousal support terminates automatically upon the remarriage of the recipient spouse or upon the death of either spouse.

Cohabitation. For non-rehabilitative support, the paying spouse may petition the court for termination on the basis that the recipient has been habitually cohabitating with another individual in a relationship analogous to a marriage for at least one year. Termination based on cohabitation is not automatic; it requires a court order supported by a preponderance of the evidence. This provision does not apply to rehabilitative spousal support awards.

Modification. A spousal support order may be modified if there is a material change in the circumstances of either party. Either spouse may petition the court for modification. Common grounds include a substantial change in income, disability, retirement, or job loss. A change that was foreseeable at the time of the original order generally does not justify modification. The party seeking modification bears the burden of demonstrating the material change.

End date in the order. Because the statute requires a limited period, every non-rehabilitative order already contains a built-in termination date. When that date arrives, the obligation ends without any further court action.

Is Spousal Support Taxable, and How It Differs From Child Support

Federal tax rules for spousal support changed significantly when the Tax Cuts and Jobs Act took effect. The treatment depends entirely on when the divorce or separation agreement was executed.

For agreements signed on or before December 31, 2018, the traditional rules apply: the paying spouse deducts support payments, and the recipient spouse includes them as taxable income.

For agreements executed after December 31, 2018, the rules are reversed. The paying spouse cannot deduct payments, and the recipient does not include them as gross income. IRS Topic No. 452 confirms this rule. If a pre-2019 agreement is later modified and the modification expressly states that the post-2018 tax rules apply, the agreement switches to the new treatment.

Child support is a completely separate obligation. Unlike spousal support, child support in North Dakota is calculated under the North Dakota Child Support Guidelines in N.D. Admin. Code 75-02-04.1, using a formula based on the parents' incomes and custody arrangement. Child support is never deductible by the paying parent or taxable to the receiving parent under any version of the law. The two obligations address entirely different purposes and are governed by different statutes.
