Minnesota residents seeking to end their marriage have two legal options: annulment or divorce. An annulment under Minnesota Statute § 518.02 declares a marriage legally void as if it never existed, while a divorce under Minnesota Statute § 518.06 terminates a valid marriage based on irretrievable breakdown. The critical difference lies in eligibility: annulment requires proving specific grounds such as fraud, mental incapacity, or underage marriage within strict time limits of 90 days to 1 year, whereas divorce is available to any married couple without requiring fault. In Minnesota, both proceedings cost $360-$402 in filing fees and address child custody, property division, and spousal maintenance under the same statutory framework.
| Key Facts | Annulment | Divorce |
|---|---|---|
| Filing Fee | $360-$375 (varies by county) | $390-$402 (varies by county) |
| Waiting Period | None | None (30 days before hearing) |
| Residency Requirement | 180 days | 180 days |
| Grounds Required | Yes (fraud, incapacity, underage, etc.) | No (irretrievable breakdown only) |
| Time Limit to File | 90 days to 1 year depending on ground | None |
| Property Division | Equitable distribution applies | Equitable distribution applies |
| Child Custody/Support | Same rules as divorce | Best interests standard |
| Legal Effect | Marriage declared void | Marriage terminated |
What Is the Difference Between Annulment and Divorce in Minnesota?
An annulment in Minnesota declares a marriage legally invalid from its inception, treating it as though it never existed under the law, while a divorce legally terminates a valid marriage that both parties acknowledge was legitimate when entered. Under Minnesota Statute § 518.02, annulment requires proving specific statutory grounds such as fraud, mental incapacity, or inability to consummate the marriage. Divorce under Minnesota Statute § 518.06 requires only a finding of irretrievable breakdown, making it accessible to any couple without proving fault or wrongdoing by either spouse.
The practical implications of choosing annulment versus divorce extend beyond legal terminology. An annulment, if granted, means you were never legally married in the eyes of Minnesota law. This distinction matters for religious purposes, immigration status, and personal records. However, Minnesota law uniquely protects individuals in annulled marriages by applying the same property division and spousal maintenance rules as divorce proceedings.
Minnesota courts treat children born during an annulled marriage the same as children of divorced parents. Under Minnesota Statute § 518.003, the court determines custody, parenting time, and child support based on the best interests of the child regardless of whether the parents obtain an annulment or divorce. The legal status of the marriage does not affect parental rights or child support obligations.
What Are the Grounds for Annulment in Minnesota?
Minnesota law recognizes two categories of invalid marriages: void marriages that are automatically invalid and voidable marriages that require court action to annul. Under Minnesota Statute § 518.01 and Minnesota Statute § 518.02, void marriages include bigamous marriages where one spouse has a living prior spouse, incestuous marriages between close blood relatives, and certain marriages involving persons under state guardianship without proper authorization. These marriages are invalid from the start and do not technically require a court decree, though obtaining one provides legal clarity.
Voidable marriages under Minnesota Statute § 518.04 require a court order to annul and include the following grounds:
- Mental incapacity: One party lacked the mental capacity to consent to marriage at the time of the ceremony, and the other party was unaware of this incapacity
- Intoxication: Consent was obtained while one party was under the influence of alcohol, drugs, or other incapacitating substances to the extent they could not provide valid consent
- Fraud or duress: Consent was obtained through fraud, misrepresentation, or force, and the parties did not voluntarily cohabit after discovering the fraud
- Physical incapacity: One party lacks the physical ability to consummate the marriage through sexual intercourse, and the other party was unaware of this at the time of marriage
- Underage marriage: One spouse was under age 18 at the time of marriage
The burden of proof in annulment cases falls on the party seeking the annulment. Minnesota courts require clear evidence establishing the specific ground claimed. For fraud cases, the misrepresentation must involve a material fact that would have prevented the marriage had the truth been known, such as concealment of a prior marriage, criminal history, or inability to have children.
What Are the Time Limits for Filing an Annulment in Minnesota?
Minnesota imposes strict deadlines for filing annulment petitions that do not apply to divorce cases. Under Minnesota Statute § 518.05, the time limits vary based on the specific ground for annulment. Missing these deadlines means the only option to end the marriage is divorce.
| Ground for Annulment | Time Limit | Starting Point |
|---|---|---|
| Mental incapacity | 90 days | After discovering the incapacity |
| Intoxication | 90 days | After learning consent was impaired |
| Fraud | 90 days | After discovering the fraud |
| Force/Duress | 90 days | After the coercion ends |
| Physical incapacity to consummate | 1 year | After discovering the incapacity |
| Underage marriage | Before age 18 | The underage party or their parent/guardian may file anytime before the minor turns 18 |
For underage marriages, once the minor spouse reaches age 18, they can no longer seek an annulment based on age and must pursue divorce if they wish to end the marriage. The short 90-day window for fraud, incapacity, or duress cases reflects the policy that parties who continue cohabiting after discovering grounds for annulment have essentially ratified the marriage.
How Does Property Division Work in Annulment vs. Divorce?
Minnesota uniquely applies the same property division rules to both annulment and divorce cases under Minnesota Statute § 518.58. The court makes a just and equitable division of marital property regardless of whether the marriage is being annulled or dissolved. This differs from most other states, where annulment cases often cannot address property division because no valid marriage existed.
Under Minnesota Statute § 518.003, marital property includes all property acquired during the time parties lived together as spouses under a purported marriage relationship that is later annulled. This means property purchased during what both parties believed was a valid marriage receives the same treatment as property in a divorce case. The court considers factors including each spouse's contribution to acquiring the property, the length of the marriage, and each party's economic circumstances.
Nonmarital property, which includes assets owned before the marriage, gifts, and inheritances received by one spouse, remains separate in both annulment and divorce proceedings. However, the court may award up to 50% of nonmarital property to the other spouse under Minnesota Statute § 518.58, subdivision 2, if doing so is necessary to prevent undue hardship.
Minnesota courts divide property equitably, not necessarily equally. Equitable distribution means a fair division based on circumstances, which may result in a 60/40, 70/30, or other split depending on factors such as the length of marriage, each spouse's earning capacity, and contributions as a homemaker. The court conclusively presumes both spouses made substantial contributions to acquiring marital property during the marriage.
Is Spousal Maintenance Available in Annulment Cases?
Minnesota courts may award spousal maintenance, commonly called alimony, in both annulment and divorce proceedings. Under Minnesota Statute § 518.552, the court considers the same factors regardless of whether the marriage is being annulled or dissolved. This includes the financial needs of the requesting spouse, the ability of the other spouse to pay, the standard of living established during the marriage, and the duration of the purported marriage.
The court examines several factors when determining spousal maintenance in either proceeding:
- The financial resources of each party, including marital property received in the division
- Time needed for the requesting party to obtain education or training for appropriate employment
- The standard of living established during the marriage
- The duration of the marriage and the age and health of both parties
- Each party's contributions to the marriage, including homemaking and career support
- The ability of the maintenance payer to meet their own needs while paying support
Temporary maintenance may be awarded during the annulment or divorce proceedings to help the dependent spouse meet immediate expenses. Permanent or long-term maintenance is more common in marriages lasting 10 years or longer, while rehabilitative maintenance for a specific period helps a spouse become self-supporting through education or job training.
What Are the Costs of Annulment vs. Divorce in Minnesota?
The filing fee for annulment in Minnesota is $360 base fee, while divorce costs $390 base fee as of 2026. Both fees include a $50 additional court fee, and counties add varying law library fees ranging from $0 to $50. Hennepin County charges $402 for divorce filings, while Washington County charges $375 for annulments. These fees should be verified with your local court clerk as they may change.
| Cost Category | Annulment | Divorce |
|---|---|---|
| Base Filing Fee | $310 | $340 |
| Additional Court Fee | $50 | $50 |
| County Law Library Fee | $0-$50 | $0-$50 |
| Total Filing Fee | $360-$410 | $390-$425 |
| Motion Filing Fee | $100 | $100 |
| Attorney Fees (Contested) | $5,000-$25,000 | $5,000-$30,000 |
| Attorney Fees (Uncontested) | $1,500-$5,000 | $1,500-$5,000 |
| Process Server | $50-$100 | $50-$100 |
Minnesota courts offer fee waivers through the in forma pauperis process for individuals who cannot afford filing fees. Applicants must submit financial disclosure forms demonstrating inability to pay. Courts may reduce fees or waive them entirely based on income and expenses.
Annulment cases often cost more in attorney fees than uncontested divorces because proving grounds requires additional evidence and potentially expert testimony. Contested divorces involving disputes over custody, property, or support typically cost $10,000 to $30,000 or more in attorney fees, while uncontested divorces where parties agree on all issues may cost $1,500 to $5,000.
How Long Does Annulment Take vs. Divorce in Minnesota?
Minnesota has no mandatory waiting period for either annulment or divorce, making both processes potentially faster than in states requiring separation periods. An uncontested annulment or divorce can be finalized in 30 to 60 days if both parties agree on all issues and the court calendar permits. Contested cases involving disputes over grounds, custody, or property division may take 6 to 18 months or longer.
For divorce cases, the petitioner must wait at least 30 days after filing before scheduling a final hearing. This is a procedural requirement, not a waiting period for reconciliation. Summary dissolution, available for couples without children and with limited assets, can be completed within 30 days after filing.
Annulment timelines depend heavily on whether the grounds are contested:
- Uncontested annulment with agreement: 4-8 weeks from filing to final decree
- Contested annulment requiring evidentiary hearing: 6-12 months
- Annulment with custody and property disputes: 8-18 months
The 180-day residency requirement under Minnesota Statute § 518.07 applies to both annulment and divorce. At least one spouse must have lived in Minnesota for 180 days (approximately 6 months) before filing either type of case. Military service members stationed in Minnesota satisfy this requirement.
How Do Child Custody and Support Work in Annulment vs. Divorce?
Minnesota courts apply identical standards for child custody and support in both annulment and divorce cases. Under Minnesota Statute § 518.17, courts determine custody based on the best interests of the child, considering factors including each parent's ability to meet the child's needs, the child's relationships with each parent, the stability of proposed living arrangements, and any history of domestic violence.
Children born during an annulled marriage have the same legal rights as children of divorced parents. The annulment does not make children illegitimate or affect their right to financial support from both parents. Minnesota law protects children regardless of whether their parents' marriage is declared void or dissolved.
Child support calculations follow the same guidelines in both proceedings. Minnesota uses an income shares model under Minnesota Statute § 518A.35 that considers both parents' gross incomes, parenting time percentages, childcare costs, and health insurance expenses. The child support amount does not depend on whether the parents are obtaining an annulment or divorce.
Parenting time schedules, legal custody decisions, and modification procedures follow the same rules whether the underlying case was an annulment or divorce. Courts focus on the children's needs rather than the technical status of the parents' marriage.
What Are the Grounds for Divorce in Minnesota?
Minnesota is a no-fault divorce state, meaning spouses do not need to prove wrongdoing to obtain a divorce. Under Minnesota Statute § 518.06, the sole ground for divorce is irretrievable breakdown of the marriage relationship. This means the marriage has broken down to the point that there is no reasonable prospect of reconciliation.
To prove irretrievable breakdown, the petitioner must demonstrate either: (1) the parties have lived separate and apart for at least 180 days before filing, or (2) there is serious marital discord adversely affecting one or both parties' attitude toward the marriage. Living separate and apart does not require separate residences; it means living as if unmarried.
If one spouse denies under oath that the marriage is irretrievably broken, Minnesota law requires a hearing where the court considers all relevant factors including the circumstances that led to filing and the prospect of reconciliation. However, courts rarely deny divorce petitions even when one spouse objects, as the objection itself often demonstrates serious marital discord.
Minnesota abolished traditional fault-based defenses to divorce under Minnesota Statute § 518.06. Defenses such as condonation, connivance, collusion, recrimination, insanity, and lapse of time no longer prevent a divorce from being granted. Marital misconduct also cannot be used as grounds to deny divorce or property division, though it may affect custody decisions if relevant to parenting ability.
When Should I Choose Annulment Over Divorce?
Annulment is appropriate when you meet the specific statutory grounds and can prove them within the required time limits. Choose annulment if you discovered fraud, such as your spouse concealing a prior marriage, criminal history, or inability to have children, within the past 90 days. Annulment also applies if consent was obtained while intoxicated, through force or duress, or if one spouse lacks mental capacity.
Religious considerations motivate many annulment requests. Some religious traditions do not recognize civil divorce, meaning only an annulment allows remarriage within the faith. However, civil annulment is separate from religious annulment, and obtaining one does not guarantee the other.
Annulment may be preferable for immigration purposes when the validity of a prior marriage affects current immigration applications. Proving the prior marriage was legally void from inception may resolve issues that divorce would not address.
Choose divorce instead of annulment when:
- More than 90 days have passed since discovering fraud, incapacity, or coercion
- More than 1 year has passed since discovering physical incapacity to consummate
- The underage spouse has turned 18
- You cannot prove any statutory ground for annulment
- You simply want to end a marriage that was valid when entered
Most people ending their marriages in Minnesota use divorce because annulment grounds are narrow and time limits strict. Approximately 95% of marriage dissolutions in Minnesota are divorces rather than annulments.

Can I get an annulment in Minnesota if my spouse lied about something important?
Minnesota courts grant annulments for fraud when a spouse misrepresented a material fact that would have prevented the marriage had the truth been known. Examples include concealing a prior undissolved marriage, lying about criminal history, hiding an inability to have children, or misrepresenting religious beliefs central to the marriage. Under Minnesota Statute § 518.05, you must file within 90 days of discovering the fraud, and you cannot have voluntarily cohabited after learning the truth. The misrepresentation must go to the essence of the marriage, not minor details.
Does Minnesota divide property in an annulment the same as divorce?
Minnesota applies identical property division rules to annulment and divorce under Minnesota Statute § 518.58. The court makes a just and equitable division of all marital property, which includes assets acquired while the parties lived together as spouses under the purported marriage. This differs from most states where annulment cannot address property division because no valid marriage existed. Minnesota recognizes that parties in an annulled marriage still shared financial lives and deserve equitable treatment.
How long do I have to live in Minnesota before filing for annulment or divorce?
Minnesota requires at least one spouse to have lived in the state for 180 days (approximately 6 months) before filing either an annulment or divorce under Minnesota Statute § 518.07. Military service members stationed in Minnesota satisfy this requirement even if they maintain legal residence elsewhere. Same-sex couples married in Minnesota may file for divorce in Minnesota even if they now live in a state that does not recognize their marriage.
What happens to children in an annulment vs. divorce in Minnesota?
Minnesota courts treat children identically in annulment and divorce proceedings. Child custody determinations follow the best interests standard under Minnesota Statute § 518.17, and child support calculations use the same income shares guidelines. Children born during an annulled marriage retain all legal rights, including inheritance rights and rights to financial support from both parents. The annulment does not affect the legal parent-child relationship or make children illegitimate.
Can I get an annulment if my spouse cannot perform sexually?
Minnesota permits annulment when one spouse lacks the physical capacity to consummate the marriage through sexual intercourse, and the other spouse was unaware of this incapacity at the time of marriage. Under Minnesota Statute § 518.05, you must file the annulment petition within 1 year of discovering the physical incapacity. This ground applies only to physical inability to engage in intercourse, not to refusal or other relationship issues. Medical evidence typically supports these cases.
Is there a waiting period for annulment or divorce in Minnesota?
Minnesota has no mandatory waiting period or separation requirement for either annulment or divorce. Unlike states requiring 6-month to 1-year separation periods, Minnesota allows immediate filing once the 180-day residency requirement is met. The only procedural delay is a 30-day waiting period between filing a divorce petition and scheduling the final hearing. Uncontested cases can be finalized in 30 to 60 days from filing.
What is the difference between a void and voidable marriage in Minnesota?
A void marriage is automatically invalid under Minnesota law and includes bigamous marriages, incestuous marriages, and marriages involving persons under state guardianship without authorization. These marriages are invalid from inception without requiring court action, though obtaining a court decree provides legal clarity. A voidable marriage under Minnesota Statute § 518.04 is valid until a court annuls it based on grounds such as fraud, mental incapacity, intoxication, or underage marriage. Voidable marriages require a petition and court order to become invalid.
Can I get spousal support in an annulment case in Minnesota?
Minnesota courts may award spousal maintenance (alimony) in annulment cases using the same standards applied in divorce proceedings. Under state law, provisions relating to property division and spousal maintenance apply to annulments for periods when either or both parties believed they had a valid marriage. The court considers factors including each party's financial needs, earning capacity, standard of living during the marriage, and duration of the relationship. This protection is unique to Minnesota and not available in most other states.
How do I prove irretrievable breakdown for divorce in Minnesota?
To prove irretrievable breakdown under Minnesota Statute § 518.06, you must demonstrate either that the parties lived separate and apart for at least 180 days before filing, or that serious marital discord adversely affects one or both parties' attitude toward the marriage. Living separately does not require separate residences. If your spouse denies under oath that the marriage is irretrievably broken, the court holds a hearing but rarely denies divorce when one spouse wants to end the marriage, as the disagreement itself demonstrates serious marital discord.
