How Cohabitation Affects Spousal Maintenance in Minnesota: A Guide for Payors and Recipients

Current as of: September 30, 2026 Alimony & Spousal Support Minnesota
In Minnesota, an ex-spouse moving in with a new partner does not automatically terminate alimony. Under state law, the court must evaluate if the cohabitation significantly decreases the recipient's economic need before it modifies or ends the payments.

When a divorce is finalized in Minnesota, spousal maintenance (often called alimony) is designed to help a lower-earning spouse meet their financial needs. But what happens if the spouse receiving maintenance moves in with a new boyfriend or girlfriend? Whether you are making payments from Minneapolis or receiving them in Duluth, you need to understand how Minnesota law views cohabitation. Simply sharing an address is not always enough to stop a monthly check.

Step-by-Step Process for Modifying Alimony in Minnesota

In 2016, the Minnesota legislature updated the law regarding cohabitation. Under Minn. Stat. § 518.552 Subd. 6, a payor can formally request the court to reduce, suspend, or terminate spousal maintenance if the recipient is living with another adult. However, the burden of proof is on the person making the payments. Here is how the process generally unfolds.

Step 1: Proving Cohabitation

Before a judge in the Hennepin County District Court, Minneapolis will hear your case, you must prove your ex-spouse is actually cohabitating, not just having a guest over occasionally. The court looks at how long they have lived together and the nature of the relationship. Many payors hire private investigators to gather evidence of shared vehicles and overnight stays. Social media posts showcasing vacations, shared holidays, and announcements of living together are also common pieces of evidence used in Minnesota family courts.

Step 2: Financial Commingling vs. Just Roommates

Minnesota courts distinguish between a romantic cohabitation that impacts finances and a simple roommate situation. The judge will analyze if the ex-spouse and the new partner are pooling their money. Are they splitting rent, groceries, and utility bills? Do they share a bank account? If an ex-spouse in St. Paul takes in a platonic roommate just to make ends meet, the court is much less likely to reduce maintenance compared to a romantic partner who is completely supporting them.

Step 3: Determining Decreased Economic Need

The ultimate test under Minnesota law is economic need. Even if cohabitation is proven, the court must decide if the recipient still needs the maintenance. If the new partner pays for the mortgage and all expenses, the ex-spouse's economic need has clearly decreased. Conversely, if the new partner is unemployed and the ex-spouse is supporting them, the economic need remains (though the court will not force you to subsidize the new partner). Cases like Bateman v. Bateman, 382 N.W.2d 240 (MN Court of Appeals 1986) show that courts closely examine actual living expenses.

Step 4: Filing the Formal Motion

If you believe you have strong evidence, you must file a formal motion with the court that issued your divorce decree. Under Minn. Stat. § 518.552 Subd. 6(c), a motion to modify spousal maintenance on the basis of cohabitation may not be brought within one year of the entry of the divorce decree, unless the parties agreed in writing or the court finds extreme hardship. To file, you will typically use Form DIV2002, Minnesota, Judicial Branch, Motion to Modify Spousal Maintenance and Notice of Hearing. You cannot simply stop paying alimony on your own; doing so can lead to severe penalties, including being held in contempt of court.

How Much Does it Cost to Modify Maintenance in Minnesota?

Going back to family court involves several expenses. While costs vary between Rochester and St. Cloud, you should generally expect the following:

Type of ExpenseEstimated Cost (USD)
Court Filing Fee (Motion)$100 (plus county law library fee)
Private Investigator (Optional)$75 - $150 per hour
Lawyer Fees$250 - $450 per hour

Because these cases rely heavily on financial discovery, hiring an experienced local lawyer from our directory is highly recommended. It is possible to spend $3,000 to $7,000 in legal fees if the ex-spouse aggressively fights the modification.

How Long Does the Process Take?

Filing a motion for modification is not an overnight fix. After filing Form DIV2002, Minnesota, Judicial Branch, Motion to Modify Spousal Maintenance and Notice of Hearing with the local court, it usually takes 4 to 8 weeks to get an initial hearing date. If the court orders a period of financial discovery (where both sides exchange bank statements), the entire process can take 3 to 6 months to resolve completely.

Frequently Asked Questions (FAQ)

Does alimony end immediately if my ex gets married?

Yes. Under Minnesota law, unless your divorce decree specifically states otherwise in a specialized agreement, spousal maintenance automatically terminates upon the remarriage of the receiving spouse.

Can I stop paying if I have proof they are living together?

No. You must continue making court-ordered payments until a judge signs an order modifying or terminating the maintenance. Stopping payments independently can result in contempt of court and wage garnishment.

What if my ex keeps their own apartment but sleeps at their partner's house?

This is a common tactic to avoid cohabitation laws. However, courts will look at where the person spends the majority of their time and if they are financially intertwined with the partner, regardless of whether they technically hold a separate lease.

Can the court force my ex's new partner to reveal their income?

Generally, a new partner's income is private. However, if there is strong evidence of financial commingling, a judge may allow limited discovery to determine exactly who is paying for the household expenses.
