To file for divorce in Minnesota, at least one spouse must have lived in Minnesota for at least 180 days, which is roughly six months, immediately before the case is filed. That is the core rule. A member of the armed services stationed in Minnesota for 180 days also qualifies, and so does someone who has been a domiciliary of the state for 180 days. Only one spouse needs to meet the requirement. If no one meets it, a Minnesota court will not grant the divorce.
The number is 180 days. One spouse must have resided in Minnesota for at least 180 consecutive days right before the petition is filed. This comes from Minnesota Statutes section 518.07, which is titled “Residence of Parties.”
People often call this a six-month rule. That is close enough in everyday conversation. In a contested case, though, the exact day count can matter. Courts look at the 180 days “immediately preceding the commencement of the proceeding,” so I count back from the filing date, not from the date you decided to divorce.
In 26 years of practice, I have seen petitions filed a few days early. When that happens, the other side can move to dismiss, and you lose time and filing fees. If you are close to the line, it is usually worth waiting the extra week.
Section 518.07 actually gives two paths. The first is residence, meaning you physically live here for 180 days. The second is domicile, meaning Minnesota is your true, fixed home even if you have been physically away.
The distinction matters more than people expect. Residence is mostly about where you sleep. Domicile is about intent. It looks at where you vote, where your driver’s license and vehicle are registered, where you pay taxes, and where you intend to return.
For most clients the two line up and the question never comes up. It surfaces in specific situations, like a recent move, a temporary work assignment, or military service. I cover each of those below.
No. Only one spouse needs to satisfy the 180-day requirement. If you have lived in Minnesota for the last six months and your spouse lives in Iowa or Texas, you can still file here. The reverse is also true. If your spouse qualifies and you do not, the case can proceed in Minnesota.
When spouses live in different states, more than one state may have the power to hear the divorce. Where you file first can shape which state’s law applies to property and support. That is a strategy conversation worth having early, not after a petition lands in another state.
If you recently moved here, your 180-day clock generally starts when you began living in Minnesota with the intent to stay. You do not have to wait if your spouse already meets the requirement on their own.
This question comes up constantly in Rochester. Olmsted County draws people from across the country who relocate for work at Mayo Clinic, and a marriage sometimes breaks down within the first months of the move. If you arrived in March and the marriage is failing by June, you likely cannot file in Minnesota yet on your own residency. You may still have options if your spouse qualifies, or if your prior state still has jurisdiction. I look at the calendar first in these cases, because the answer often turns on a handful of days.
If you genuinely intend to make Minnesota home, you can also build the record that supports domicile. Register to vote, change your license, and update your tax filings. Those steps matter if residency is later challenged.
Military families get specific treatment, and it runs both directions.
If you kept Minnesota as your legal home of record but you are currently stationed elsewhere on active duty, you can still file for divorce in Minnesota. Your domicile here carries the residency requirement even though you are physically gone. Section 518.07 is built to allow exactly this through its domicile path.
The flip side also counts. A service member stationed in Minnesota for at least 180 days meets the residency requirement through that posting, even without being a long-term Minnesota resident. So an active-duty member assigned to a Minnesota duty station for six months can file here.
One more practical point for deployed spouses. The federal Servicemembers Civil Relief Act can pause a divorce while a service member is on active duty and unable to participate. That protection does not block the filing. It can delay the timeline, so plan for it.
Usually no, but there is a narrow exception. Under section 518.07, subdivision 2, a Minnesota court can hear a divorce even when neither spouse lives here if the marriage was performed in Minnesota and neither spouse lives in a state that will grant the divorce because of the spouses’ sex or sexual orientation.
This provision exists for couples who married in Minnesota but later moved somewhere that will not dissolve their marriage. It is a limited safety valve, not a general route for out-of-state couples. If you think it applies to you, have a lawyer confirm it before filing.
This is where divorce and legal separation part ways. The 180-day durational requirement in section 518.07 is written for dissolution, meaning divorce. Section 518.06, which governs legal separation, does not impose that same 180-day waiting period.
In practice, that means a legal separation can sometimes be available sooner than a divorce for a person who has not yet lived here six months. The court still needs proper jurisdiction and venue over the parties, so this is not a loophole around all the rules. It is a real difference in the durational requirement, and it occasionally gives a recent arrival a path forward while the divorce clock runs.
I want to flag this one for you to confirm against your own read, Jason, because it is a fine statutory point that opposing counsel sometimes argues differently.
Minnesota divorce is filed at the county level. Under Minnesota Statutes section 518.09, a dissolution or legal separation is venued in the county where either spouse resides.
If you and your spouse live apart, two counties may both be proper. A couple in Rochester files in Olmsted County. A couple in Mankato files in Blue Earth County. When spouses live in different counties, the case can often be filed in either, and the first valid filing usually sets the venue.
For service members, section 518.09 adds that if jurisdiction rests on a Minnesota posting, the case can be brought in the county where the member is stationed. Venue can later be changed for convenience or fairness, but it is far easier to file in the right county from the start.
If no spouse meets the residency or domicile requirement, the court lacks the authority to grant the divorce. The other side can challenge it, and the petition can be dismissed. You would refile once the requirement is met, after losing time and fees.
If you are unsure whether you qualify, count the days carefully and look at residency and domicile both. When the timing is tight, a short wait usually beats a dismissal. For official forms and self-help guidance, the Minnesota Judicial Branch divorce help page is a reliable starting point.
Residency sounds like a simple box to check, but it decides whether your case can even start, and sometimes which state’s law controls your property and support. If you are newly arrived in southern Minnesota, serving in the military, or living apart from your spouse across state lines, the timing deserves a careful look.
