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 factors, now codified in the statute, 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 limits. Every non-rehabilitative spousal support order must include a specific end date.

The statute also caps that duration against the length of the marriage. 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 duration is the one the parties agree upon or a limited time the court determines.

These percentages are ceilings rather than floors. A judge may award a shorter term within any range. Going the other way is not free discretion: N.D.C.C. 14-05-24.1(5) applies the schedule except upon written findings by the court that a deviation beyond the time limits of the section is necessary, so a court that wants to run support past the applicable cap has to say so on the record and explain why.

The statute's termination provisions for remarriage, death, and cohabitation apply to spousal support generally, with no carve-out for rehabilitative awards. The distinction the statute does draw between rehabilitative and general term support is in the separate modification provisions: a material change in circumstances can trigger modification of rehabilitative support during the rehabilitative period, and of general term support at any time. Rehabilitative support otherwise 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 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 factors. These began as case-law criteria applied by the North Dakota Supreme Court, but HB 1037 codified them in N.D.C.C. 14-05-24.1(3) as factors the court shall consider, in addition to any other factors it finds relevant. They are mandatory statutory considerations now, not merely judicial guidelines.

The factors listed in N.D.C.C. 14-05-24.1(3) are:

1. The age of the parties
2. The earning ability of each party
3. The duration of the marriage
4. The conduct of the parties during the marriage
5. The station in life of each party
6. The circumstances and necessities of each party
7. The health and physical condition of each party
8. The financial circumstances of the parties as shown by the property owned at the time of the divorce, including the value of that property, its income-producing capacity, and whether it was acquired before or after the marriage

No single factor is controlling. The judge weighs all eight factors together in light of the full evidentiary record, and may consider any other factor the court finds relevant. 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. Like other spousal support under the statute, rehabilitative support terminates automatically upon the remarriage or death of the spouse receiving support, and can be terminated for habitual cohabitation on a court order; the statute does not exempt rehabilitative awards from these 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. The modification bar attaches at judgment, not at payment: under N.D.C.C. 14-05-24.1(7), once a judgment is filed the parties may not seek, and the court may not order, a modification of lump sum spousal support.

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 agree otherwise in writing, spousal support terminates upon the remarriage or death of the spouse receiving support. Note what that does not say: the payor's death is not a termination event. Instead, N.D.C.C. 14-05-24.1(9) lets the court require reasonable security from the payor spouse in the event of the payor's death, so the obligation can be made to survive the payor. The same subsection requires the recipient to notify the payor of a remarriage immediately, at the payor's last known address.

Cohabitation. 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. The statute applies this provision to spousal support generally, including rehabilitative awards.

Retirement. Under N.D.C.C. 14-05-24.1(11), there is a rebuttable presumption that spousal support terminates when the paying spouse reaches full retirement age for Social Security purposes. The recipient can overcome the presumption by showing the court that support should continue based on statutory factors, including the parties’ ages at marriage and at the award, and the degree and duration of the recipient’s economic dependency.

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.

Frequently Asked Questions

Does North Dakota allow permanent spousal support?

No. N.D.C.C. 14-05-24.1 explicitly prohibits permanent spousal support. Every award must be for a limited, defined period of time. The statute was significantly amended by HB 1037 in 2023 (effective August 1, 2023), which added the explicit prohibition, type definitions, and duration percentage limits. The court must set a specific end date in the order.

What are the Ruff-Fischer factors in North Dakota?

The Ruff-Fischer factors are the considerations N.D.C.C. 14-05-24.1(3) requires a North Dakota court to weigh when deciding whether to award spousal support and in what amount. They originated in North Dakota Supreme Court case law and were codified in the statute by HB 1037 in 2023, so a court shall consider them rather than merely being guided by them. They are the age of the parties, the earning ability of each party, the duration of the marriage, the conduct of the parties during the marriage, the station in life of each party, the circumstances and necessities of each party, the health and physical condition of each party, and the financial circumstances shown by the property owned at the time of the divorce. No single factor controls the outcome, and the court may weigh any other factor it finds relevant.

How long does spousal support last in North Dakota?

Duration depends on marriage length and the Ruff-Fischer factors. The statute sets caps: up to 50 percent of the marriage for unions under five years, scaling to up to 80 percent for marriages of fifteen to twenty years. For marriages over twenty years, the duration is the one the parties agree upon or a limited time the court determines. Those percentages are ceilings, and under N.D.C.C. 14-05-24.1(5) a court may run support beyond the applicable time limit only upon written findings that a deviation is necessary. Rehabilitative support runs for the period needed to complete education or training.

Does spousal support end if the recipient remarries?

Yes. Under N.D.C.C. 14-05-24.1(9), spousal support terminates upon the remarriage or death of the spouse receiving support, unless the parties agree otherwise in writing, and the recipient must notify the payor of the remarriage immediately. This applies to rehabilitative spousal support as well as general term support; the statute does not carve out rehabilitative awards from the remarriage termination provision. The payor's own death is not listed as a termination event, and the court may require reasonable security from the payor in the event of the payor's death.

Can cohabitation end spousal support in North Dakota?

It can, but not automatically. The paying spouse may petition the court to terminate the award by showing, by a preponderance of the evidence, that the recipient has been habitually cohabitating with another individual in a marriage-like relationship for at least one year. A court order is required, and the statute applies this provision to spousal support generally, including rehabilitative awards.

Is spousal support taxable in North Dakota?

The answer depends on when the divorce agreement was signed. For agreements executed after December 31, 2018, spousal support is not deductible by the payer and is not taxable income for the recipient under federal law. For agreements signed on or before December 31, 2018, the old rules apply: the payer could deduct payments, and the recipient included them as income. North Dakota conforms to federal tax treatment.

What is the difference between spousal support and child support in North Dakota?

Spousal support is paid between spouses and is discretionary, based on the Ruff-Fischer factors and mutual financial need. Child support is calculated under the mandatory North Dakota Child Support Guidelines formula and is owed to support the child, not the other parent. Child support is never deductible or taxable; spousal support tax treatment depends on the agreement date. The two obligations are separate and can coexist.
