Michigan law provides two distinct paths for ending a marriage: annulment and divorce. An annulment under MCL 552.1-552.39 legally declares that a valid marriage never existed, while a divorce under Michigan's no-fault statute terminates a legally valid marriage. The filing fee for both proceedings ranges from $175 without minor children to $255 with minor children as of March 2026. Michigan grants approximately 25,000 divorces annually but fewer than 500 annulments, reflecting the strict evidentiary requirements for annulment under state law.

What Is an Annulment in Michigan?
An annulment in Michigan is a court order declaring that a marriage was legally invalid from its inception, effectively erasing the marriage as though it never occurred. Under MCL 552.1, Michigan courts recognize six specific grounds for annulment, and the petitioning spouse must prove at least one ground by clear and convincing evidence. Unlike divorce, which ends a valid marriage prospectively, annulment operates retroactively to void the marital contract ab initio (from the beginning).
Michigan distinguishes between void marriages and voidable marriages in annulment proceedings. A void marriage, such as one involving bigamy under MCL 552.1 or prohibited consanguinity under MCL 551.3, is invalid from inception and requires no judicial action to dissolve, though parties typically seek a court order for clarity. A voidable marriage, such as one obtained through fraud under MCL 552.37, remains legally valid until one party petitions the court for annulment. The annual number of annulments filed in Michigan represents less than 2% of all marriage dissolution proceedings, demonstrating the high evidentiary bar required.
What Is a Divorce in Michigan?
A divorce in Michigan is the legal termination of a valid marriage, governed primarily by MCL 552.6 which establishes Michigan as a no-fault divorce state. The petitioning spouse need only assert that there has been a breakdown of the marriage relationship to the extent that the objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved. Michigan courts granted 25,847 divorces in 2024, with the average uncontested divorce finalizing within 3-4 months and contested divorces taking 12-24 months.
The filing fee for divorce in Michigan is $175 without minor children or $255 with minor children, plus an $80 judgment fee due at the time of filing. Under MCL 552.9, at least one spouse must have resided in Michigan for 180 days and in the filing county for 10 days immediately preceding the complaint. The mandatory waiting period under MCL 552.9f is 60 days for divorces without minor children and 180 days for divorces involving minor children, though courts may reduce the 180-day period to 60 days upon showing unusual hardship or compelling necessity.
The 6 Grounds for Annulment in Michigan
Michigan law recognizes exactly six statutory grounds for annulment, each codified in the Michigan Compiled Laws. The petitioner bears the burden of proving the alleged ground by clear and convincing evidence, a higher standard than the preponderance of evidence used in divorce proceedings. Approximately 65% of annulment petitions in Michigan cite fraud or bigamy as the primary ground.
Bigamy (MCL 552.1)
A marriage is void ab initio if either party was legally married to another person at the time of the ceremony. Under MCL 552.1, no judicial decree is technically required to void a bigamous marriage, but courts routinely issue annulment orders to clarify legal status. The innocent spouse may file for annulment at any time, even after the death of either party, and the bigamous spouse may face criminal prosecution under MCL 750.439, which classifies bigamy as a felony punishable by up to 4 years imprisonment or a $2,000 fine.
Consanguinity or Affinity (MCL 551.3-551.4)
Marriages between close blood relatives are void ab initio under Michigan law. MCL 551.3 prohibits marriages between ancestors and descendants, siblings (including half-siblings), aunts/uncles and nieces/nephews, and first cousins. MCL 551.4 extends these prohibitions to relationships created by adoption. Unlike voidable marriages, consanguineous marriages may be challenged by any interested party at any time, including after the death of one or both spouses.
Underage Marriage (MCL 551.51, 552.34)
Michigan requires parties to be at least 18 years old to marry without parental consent, or at least 16 years old with written consent from a parent or legal guardian. Under MCL 552.34, a marriage involving a person under 16 is void ab initio, while a marriage involving a person aged 16-17 without proper parental consent is voidable. The underage spouse, a parent, or a legal guardian may petition for annulment. If the underage spouse reaches 18 and voluntarily continues the marriage, the right to annulment may be waived.
Force or Duress (MCL 552.37)
A marriage obtained through force, threats, or coercion is voidable under MCL 552.37. The coerced spouse must demonstrate that their consent was not freely given due to external pressure sufficient to overcome their free will. However, voluntary cohabitation as husband and wife after discovering the force or duress bars the annulment claim. There is no specific statute of limitations; the cohabitation bar serves as the practical time limit. Courts have granted annulments where one party was threatened with physical harm, immigration consequences, or family retaliation.
Fraud or Misrepresentation (MCL 552.37)
Fraud constitutes grounds for annulment when one party made a material misrepresentation that induced the other party to marry. Under MCL 552.37, the fraud must go to the essence of the marital relationship. Michigan courts have found sufficient fraud in cases involving concealed inability or refusal to have children, concealed sexual orientation in heterosexual marriages, undisclosed prior marriages, and concealed terminal illness. General character misrepresentations or exaggerated financial status typically do not qualify. Voluntary cohabitation after discovering the fraud bars the annulment claim.
Mental Incapacity (MCL 552.36)
A marriage is voidable if one party lacked the mental capacity to understand the nature of the marriage contract at the time of the ceremony. Under MCL 552.36, grounds include mental illness, intellectual disability, or intoxication (voluntary or involuntary) sufficient to destroy understanding and free will. A third party, such as a guardian, may file on behalf of the incapacitated person. Voluntary cohabitation after regaining capacity bars the annulment claim for the formerly incapacitated spouse.
Physical Incapacity (MCL 552.39)
A marriage is voidable if one party was physically incapable of consummating the marriage and this incapacity existed at the time of the ceremony. Under MCL 552.39, only the affected spouse (the one alleging incapacity of the other) may file. This ground has a strict 2-year statute of limitations from the date of the marriage ceremony, making it the only annulment ground with an express time limit. The incapacity must be permanent; temporary conditions do not qualify.
Key Differences: Annulment vs. Divorce in Michigan
The choice between annulment and divorce in Michigan involves significant legal, financial, and practical distinctions that affect property rights, support obligations, and future legal status. Understanding these differences helps parties make informed decisions about which proceeding best serves their interests. Approximately 95% of marriage dissolution cases in Michigan proceed as divorces rather than annulments due to the evidentiary challenges and limited availability of annulment grounds.
Legal Effect on the Marriage
| Aspect | Annulment | Divorce |
|---|---|---|
| Marriage Status | Declared void ab initio | Terminated prospectively |
| Legal Record | Marriage deemed to have never existed | Marriage existed, now ended |
| Duration of Marriage | Not applicable | Calculated for support/property |
An annulment under Michigan law treats the marriage as legally null from inception, while a divorce acknowledges the marriage existed and terminates it as of the judgment date. This distinction affects pension calculations, Social Security benefits, and survivor rights. A divorced spouse married for 10 or more years may qualify for Social Security benefits based on the former spouse's record, while an annulled spouse cannot claim such benefits regardless of cohabitation duration.
Property Division
Michigan follows equitable distribution principles in divorce proceedings under MCL 552.401, dividing marital property fairly (though not necessarily equally) based on factors including length of marriage, contribution to marital estate, earning capacity, and fault. Annulment proceedings treat the marriage as having never existed, meaning technically there is no marital property to divide. Courts typically restore property to its original ownership where possible, though they retain discretion to fashion equitable remedies to prevent unjust enrichment.
Spousal Support (Alimony)
Spousal support is generally not available following an annulment in Michigan because no valid marriage existed from which support obligations could arise. In divorce proceedings, courts may award temporary or permanent spousal support under MCL 552.23, considering factors including duration of marriage, ability to pay, needs of the recipient spouse, age and health, and standard of living during marriage. The absence of spousal support in annulment cases represents a significant financial distinction, particularly in longer-duration marriages.
Waiting Periods
Michigan imposes no mandatory waiting period for annulment proceedings. An annulment case can proceed to judgment as soon as the court's calendar permits, provided proper service has been completed and the respondent has had opportunity to respond. Divorce proceedings require a 60-day waiting period under MCL 552.9f when no minor children are involved, and a 180-day waiting period when minor children exist. The 180-day period may be reduced to 60 days upon demonstration of unusual hardship or compelling necessity.
Children of the Marriage
Children born during an annulled marriage are legitimate under Michigan law and entitled to the same custody, parenting time, and support protections as children of divorced parents. The Michigan Child Custody Act (MCL 722.21 et seq.) governs all custody determinations based on the child's best interests. Child support obligations are calculated using the Michigan Child Support Formula regardless of whether the parents' marriage was annulled or divorced. The annulment does not affect the child's legitimacy or inheritance rights.
How to Get an Annulment in Michigan
Filing for annulment in Michigan requires meeting residency requirements, identifying valid statutory grounds, gathering evidence, and navigating the family court system. The process typically costs between $1,500 and $10,000 in total expenses including filing fees, attorney fees, and related costs, compared to $2,000 to $15,000 for an average divorce. Annulment cases often require more extensive evidence gathering than no-fault divorces.
Step 1: Verify Residency Requirements
Under MCL 552.9, at least one spouse must have resided in Michigan for 180 days immediately preceding the filing and in the filing county for 10 days. An exception applies under MCL 552.9 when the defendant was born in or is a citizen of a foreign country and minor children are involved, allowing filing in any Michigan county without the 10-day county residency requirement.
Step 2: Identify Statutory Grounds
The petitioner must identify which of the six statutory grounds applies to their situation: bigamy, consanguinity, underage marriage, force or duress, fraud, mental incapacity, or physical incapacity. Evidence requirements vary by ground. Bigamy requires proof of the prior undissolved marriage (certified marriage records, lack of divorce decree). Fraud requires proof of the material misrepresentation and reliance upon it.
Step 3: File the Complaint
File a Complaint for Annulment with the Family Division of the Circuit Court in the appropriate county. The filing fee is $175 without minor children or $255 with minor children as of March 2026. The complaint must specifically allege the statutory ground(s) for annulment and the facts supporting the claim. Unlike a divorce complaint, which simply alleges breakdown of the marriage relationship, an annulment complaint must contain detailed factual allegations.
Step 4: Serve the Respondent
The respondent must be formally served with the complaint and summons. Service options include personal service by a process server ($25-$75), service by certified mail with return receipt, or service by publication if the respondent cannot be located. The respondent has 21 days to file a response if served within Michigan, or 28 days if served outside the state.
Step 5: Prove the Grounds
The petitioner must prove the alleged grounds by clear and convincing evidence, meaning the evidence must establish that the claim is substantially more likely to be true than not. This is a higher standard than the preponderance of evidence (more likely than not) used in most civil cases. Documentary evidence, witness testimony, and expert testimony may be required depending on the ground alleged.
Step 6: Obtain the Judgment
If the court finds the petitioner has met the burden of proof, it will enter a judgment of annulment. The judgment addresses custody, parenting time, and child support if children exist, and may address property issues to prevent unjust enrichment. The judgment can be entered as soon as the evidentiary requirements are satisfied, with no mandatory waiting period.
How to File for Divorce in Michigan
Filing for divorce in Michigan is procedurally simpler than annulment because no specific grounds must be proven beyond the statutory no-fault allegation. The total cost ranges from $1,675 for a simple uncontested divorce to $30,000 or more for complex contested cases involving custody disputes, business valuations, or extensive litigation. The median cost for a divorce with attorney representation in Michigan is approximately $8,500.
Step 1: Meet Residency Requirements
At least one spouse must have resided in Michigan for 180 days and in the filing county for 10 days under MCL 552.9. If the grounds for divorce occurred outside Michigan, MCL 552.9e requires one full year of state residency before filing.
Step 2: File the Complaint for Divorce
File a Complaint for Divorce with the Family Division of the Circuit Court. The filing fee is $175 without minor children or $255 with minor children, plus an $80 judgment fee. The complaint need only allege that there has been a breakdown of the marriage relationship to the extent that the objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved.
Step 3: Serve the Defendant
The defendant must be served with the complaint and summons. Service costs range from $25-$75 depending on method. The defendant has 21 days (28 days if served outside Michigan) to respond.
Step 4: Complete the Waiting Period
No proofs or testimony may be taken until the expiration of the waiting period under MCL 552.9f: 60 days for divorces without minor children, 180 days for divorces with minor children. The 180-day period may be reduced to 60 days upon showing unusual hardship or compelling necessity, but the initial 60 days cannot be waived under any circumstances.
Step 5: Negotiate Settlement or Proceed to Trial
Approximately 95% of Michigan divorces settle before trial. Settlement negotiations address property division, spousal support, child custody, parenting time, and child support. If settlement is not possible, the court will schedule trial and resolve disputed issues.
Step 6: Obtain the Judgment of Divorce
The court enters a Judgment of Divorce resolving all issues. The judgment must address division of property (including retirement accounts) under MCL 552.101, custody and parenting time under the Child Custody Act, child support under the Michigan Child Support Formula, and spousal support if awarded.
Annulment vs. Divorce: Which Should You Choose?
Choosing between annulment and divorce depends on whether valid annulment grounds exist, your goals regarding property and support, and practical considerations about evidence and timing. Approximately 85% of people who initially inquire about annulment ultimately file for divorce because they cannot establish the required statutory grounds. An experienced family law attorney can evaluate your specific circumstances and recommend the appropriate proceeding.
When Annulment May Be Appropriate
Annulment may be the better choice when you can prove one of the six statutory grounds, you want the marriage legally treated as though it never existed, spousal support is not a concern (you do not need it or want to avoid paying it), property division can be resolved by returning assets to original owners, and religious or cultural reasons make annulment preferable. The Catholic Church, for example, requires a civil annulment as a prerequisite for obtaining a religious declaration of nullity.
When Divorce Is the Better Option
Divorce is typically more appropriate when no valid annulment grounds exist, you need the certainty of no-fault proceedings, spousal support may be necessary, equitable distribution of marital property is required, and faster resolution is desirable once the waiting period expires. Most couples do not have valid annulment grounds, making divorce the only option for legally ending the marriage.
Frequently Asked Questions
How much does an annulment cost in Michigan?
The court filing fee for annulment in Michigan is $175 without minor children or $255 with minor children as of March 2026. Total costs including attorney fees typically range from $1,500 to $10,000 depending on case complexity, whether the annulment is contested, and evidence gathering requirements. Verify current fees with your local county clerk.
How long does an annulment take in Michigan?
Michigan imposes no mandatory waiting period for annulment, unlike the 60-180 day waiting periods for divorce. An uncontested annulment can finalize within 30-60 days after filing if service is completed promptly and the respondent does not contest. Contested annulments may take 6-12 months or longer depending on discovery needs and court scheduling.
Can I get an annulment if we've been married for years?
Yes, duration of marriage does not automatically bar annulment in Michigan. However, voluntary cohabitation after discovering fraud or duress bars annulment on those grounds under MCL 552.37. Physical incapacity annulments must be filed within 2 years of the marriage under MCL 552.39. Bigamy and consanguinity grounds have no time limit.
What happens to our children if we get an annulment?
Children born during an annulled marriage remain legitimate under Michigan law. The Michigan Child Custody Act (MCL 722.21 et seq.) governs custody and parenting time based on the child's best interests, identical to divorce proceedings. Child support is calculated using the Michigan Child Support Formula regardless of whether the marriage was annulled or divorced.
Does an annulment affect property rights?
Yes. Because annulment declares the marriage never legally existed, there is technically no marital property to divide. Courts typically restore property to original ownership where possible. This differs from divorce, where Michigan's equitable distribution principles under MCL 552.401 divide marital property fairly based on multiple factors.
Can I get spousal support after an annulment?
Generally no. Spousal support (alimony) is typically not available following annulment because no valid marriage existed from which support obligations could arise. This represents a significant financial difference from divorce, where courts may award temporary or permanent support under MCL 552.23.
What if my spouse contests the annulment?
If your spouse contests the annulment, you must prove your alleged grounds by clear and convincing evidence at trial. The respondent may argue that no valid ground exists, that you waived the right to annulment through voluntary cohabitation, or that you failed to file within applicable time limits. Contested annulments require more extensive litigation than uncontested cases.
Is fraud sufficient grounds for annulment in Michigan?
Fraud is grounds for annulment only when it goes to the essence of the marital relationship. Under MCL 552.37, Michigan courts have granted annulments for fraud involving concealed inability or refusal to have children, concealed prior marriages, and undisclosed terminal illness. General character misrepresentations typically do not qualify. Voluntary cohabitation after discovering the fraud bars the claim.
Can I file for annulment if my spouse was already married?
Yes. Bigamy is grounds for annulment under MCL 552.1, and a bigamous marriage is void ab initio (from the beginning). There is no time limit for filing, and the innocent spouse may obtain annulment at any time. The bigamous spouse may also face criminal prosecution for felony bigamy under MCL 750.439.
Where do I file for annulment in Michigan?
File your Complaint for Annulment with the Family Division of the Circuit Court in the county where you or your spouse has resided for at least 10 days, provided at least one of you has lived in Michigan for 180 days under MCL 552.9. Filing fees range from $175-$255 depending on whether minor children are involved.
