Living with a new partner does not automatically end spousal maintenance (alimony) in Minnesota. Under Minn. Stat. § 518.552, subdivision 6, cohabitation with another adult can serve as grounds for modification, but courts must evaluate four specific factors before reducing, suspending, or terminating maintenance. The maintenance payor must prove that the cohabitation arrangement provides economic benefit to the recipient, making continued support unreasonable and unfair. Minnesota law imposes a one-year waiting period before any cohabitation-based modification motion can be filed, and courts retain significant discretion in evaluating these cases.

What Minnesota Law Says About Cohabitation and Spousal Maintenance
Minnesota courts can modify spousal maintenance when the recipient cohabits with another adult, but cohabitation alone does not automatically terminate support payments. Under Minn. Stat. § 518.552, subdivision 6, enacted in 2016, the court must find that cohabitation makes the existing maintenance order unreasonable and unfair before ordering any modification. The modification options include reduction, suspension, reservation, or termination of maintenance payments.
The 2016 legislative amendment codified principles the Minnesota Supreme Court first established in 1979, recognizing that a meretricious relationship (unmarried cohabitation) may justify alimony modification to the extent it improves the recipient's economic well-being. However, Minnesota law requires proof of actual economic benefit, not merely the existence of a romantic relationship or shared residence.
The Four-Factor Test for Cohabitation Modification
When evaluating whether cohabitation alimony Minnesota cases warrant modification, courts must consider all four statutory factors:
-
Whether the obligee would marry the cohabitant but for the maintenance award: Courts examine whether the recipient is avoiding marriage specifically to preserve alimony payments, which would indicate the relationship provides sufficient financial security to replace maintenance.
-
The economic benefit the obligee derives from the cohabitation: This is typically the most important factor, requiring evidence of shared expenses, reduced housing costs, or financial contributions from the new partner that decrease the recipient's need for support.
-
The length of the cohabitation and the likely future duration: Short-term cohabitation or unstable living arrangements receive less weight than established, long-term relationships demonstrating permanence and financial interdependence.
-
The economic impact on the obligee if maintenance is modified and the cohabitation ends: Courts consider whether terminating maintenance would leave the recipient financially vulnerable if the new relationship dissolves.
How Courts Prove Economic Benefit from Cohabitation
Minnesota courts require concrete evidence of economic benefit before modifying maintenance based on living with a boyfriend alimony or new partner alimony situations. In Bateman v. Bateman, 382 N.W.2d 240 (Minn. Ct. App. 1986), the court established that cohabitation warrants maintenance modification only if it materially reduces the recipient's need for support. This principle has been consistently upheld in subsequent cases.
Types of Evidence That Demonstrate Economic Benefit
Minnesota courts have accepted the following evidence to prove economic benefit from cohabitation:
- Shared housing costs where the new partner pays rent or mortgage contributions (typically reducing housing expenses by 40-60%)
- Joint utility accounts showing the cohabitant contributes to monthly bills averaging $200-$400
- Shared grocery and household expenses reducing the recipient's monthly costs by $300-$500
- The new partner's payment of vehicle expenses, insurance, or other living costs
- Evidence the recipient has accumulated savings or reduced debt since cohabitation began
- Bank statements showing deposits from the cohabitant or increased disposable income
Evidence That May Not Support Modification
In Reppe v. Reppe, No. A20-0464 (Minn. Ct. App. 2021), the court declined to modify maintenance because cohabitation did not materially reduce the recipient's expenses. Similarly, in Helms v. Helms, No. A17-0854 (Minn. Ct. App. 2017), the court refused termination without proof that the shared household arrangement actually reduced the ex-wife's financial need. Courts have consistently held that the following evidence alone is insufficient:
- Mere presence of a romantic partner in the home
- Social media posts suggesting a committed relationship
- Joint vacation photographs or public appearances
- Testimony from neighbors about overnight stays
- The fact that the new partner has significant income
Procedural Requirements for Filing a Cohabitation Motion
Minnesota law imposes specific procedural requirements before a supportive relationship can serve as grounds for maintenance modification. The paying spouse must follow strict timelines and evidentiary standards to succeed in reducing or terminating payments.
The One-Year Waiting Period
Under Minn. Stat. § 518.552, subd. 6, a motion to modify spousal maintenance based on cohabitation may not be filed within one year of the divorce decree or legal separation order. This waiting period applies regardless of when the cohabitation began. However, two exceptions exist:
-
Written agreement: The parties may agree in their divorce settlement that cohabitation motions can be filed before the one-year period expires.
-
Extreme hardship: The court may allow an earlier motion if it finds that waiting would create extreme hardship for one of the parties.
Filing Fees and Court Costs
As of March 2026, the filing fee for a motion to modify spousal maintenance in Minnesota is approximately $100. This is separate from the initial divorce filing fee of $390-$402. County-specific surcharges of $7-$12 for law library fees may apply. Fee waiver applications under the in forma pauperis process are approved in approximately 15-20% of family law cases.
Burden of Proof
The party seeking modification bears the burden of proving:
- Cohabitation exists between the maintenance recipient and another adult
- The cohabitation provides economic benefit to the recipient
- The economic benefit makes the current maintenance order unreasonable and unfair
- All four statutory factors weigh in favor of modification
What Happens When Cohabitation Ends
Minnesota courts must consider the fourth statutory factor: the economic impact on the recipient if maintenance is modified and the cohabitation ends. This consideration often leads courts to suspend rather than terminate maintenance, preserving the recipient's ability to seek reinstatement if the new relationship dissolves.
Suspension vs. Termination
When cohabitation alimony Minnesota modifications are granted, courts may choose among several options:
- Reduction: Maintenance payments decrease but do not end entirely (common when cohabitation provides partial economic benefit)
- Suspension: Payments pause while cohabitation continues but may resume if the relationship ends (appropriate when the cohabitation's permanence is uncertain)
- Reservation: The court reserves jurisdiction to address maintenance in the future without setting a specific amount
- Termination: Maintenance ends permanently (typically reserved for long-term cohabitation with clear financial interdependence)
Reinstatement After Cohabitation Ends
If maintenance was suspended rather than terminated, the recipient may file a motion to reinstate payments if the cohabitation relationship ends. The recipient must demonstrate that:
- The cohabitation has genuinely ended
- The recipient's financial need has returned to previous levels
- The original circumstances justifying maintenance still exist
Karon Waivers and Private Agreements
Minnesota law allows divorcing spouses to address cohabitation in their divorce settlement through Karon waivers, named after the 1988 case Karon v. Karon. These agreements can modify or eliminate the court's authority to change maintenance based on cohabitation or other changed circumstances.
Types of Karon Waiver Provisions
Spouses negotiating divorce settlements can include provisions that:
- Automatically reduce maintenance by a specified percentage (typically 25-50%) upon cohabitation
- Terminate maintenance immediately upon cohabitation regardless of economic benefit
- Prohibit any modification of maintenance for any reason, including cohabitation
- Define what constitutes cohabitation (e.g., living together for 90+ consecutive days)
- Require specific evidence before modification can occur
Enforceability Requirements
Under Minn. Stat. § 518.552, subd. 5, Karon waivers must meet three requirements to be enforceable:
- Fair and equitable: The court must make specific findings that the agreement is fair to both parties
- Supported by consideration: Each party must receive something of value in exchange for the waiver
- Full financial disclosure: Both parties must have provided complete disclosure of their financial circumstances
2024 Updates to Minnesota Spousal Maintenance Law
Effective August 1, 2024, Minnesota updated its spousal maintenance terminology and guidelines under amendments to Minn. Stat. § 518.552. These changes affect how living with a boyfriend alimony and new partner alimony situations may be evaluated going forward.
New Terminology
Minnesota now distinguishes between:
- Transitional maintenance: Support for a defined period to help the recipient become self-supporting (formerly called temporary maintenance)
- Indefinite maintenance: Open-ended support without a set termination date (formerly called permanent maintenance)
Awards issued before August 1, 2024 retain their previous designations but are deemed transitional or indefinite under the new framework.
Standardized Duration Guidelines
The 2024 amendments introduced guidelines for maintenance duration based on marriage length:
| Marriage Length | Transitional Maintenance Duration |
|---|---|
| Under 5 years | Up to 50% of marriage length |
| 5-10 years | 50-75% of marriage length |
| 10-20 years | 75-100% of marriage length |
| Over 20 years | Indefinite maintenance possible |
These guidelines affect cohabitation cases because shorter maintenance terms may conclude before cohabitation issues arise, while indefinite maintenance remains subject to modification throughout its duration.
Comparison: Minnesota vs. Neighboring States
Understanding how Minnesota's cohabitation alimony laws compare to neighboring states helps illustrate the relative protections and limitations for both payors and recipients.
| State | Automatic Termination | Cohabitation Standard | Waiting Period |
|---|---|---|---|
| Minnesota | Remarriage only | Economic benefit required | 1 year |
| Wisconsin | Remarriage only | No specific cohabitation statute | None |
| Iowa | Remarriage only | Material change in circumstances | None |
| North Dakota | Remarriage only | Cohabitation may reduce | None |
| South Dakota | Remarriage only | Court discretion | None |
Minnesota's approach is moderately protective of maintenance recipients compared to states that automatically terminate support upon cohabitation. The one-year waiting period and four-factor test provide time and procedural safeguards before modification can occur.
Practical Strategies for Both Parties
Whether you are paying or receiving spousal maintenance, understanding strategic considerations can help protect your interests in supportive relationship situations.
For Maintenance Payors
- Document evidence of cohabitation carefully, including lease agreements, utility bills, and financial records
- Wait the full one-year period unless extreme hardship applies
- Focus evidence on economic benefit, not the romantic nature of the relationship
- Consider hiring a forensic accountant to analyze the recipient's household expenses before and after cohabitation
- File the motion promptly once evidence is sufficient, as delays may suggest acquiescence
For Maintenance Recipients
- Maintain separate finances from any cohabitant to minimize evidence of economic benefit
- Keep detailed records of your personal expenses and financial contributions
- Consider the terms of your divorce decree regarding Karon waivers before cohabitating
- Understand that casual dating or occasional overnight stays typically do not constitute cohabitation
- Consult an attorney before moving in with a new partner to understand the potential consequences
