Wisconsin offers two distinct legal pathways to end a marriage: annulment and divorce. Under Wis. Stat. § 767.313, an annulment declares that a valid marriage never existed, requiring proof of specific legal defects such as fraud, bigamy, or incapacity. Divorce under Wis. Stat. § 767.315 simply ends a valid marriage based on irreconcilable differences. The filing fee for both proceedings is $184.50 in most Wisconsin counties, though annulments have no waiting period while divorces require a mandatory 120-day waiting period—the longest in the nation. Understanding the differences between annulment vs divorce Wisconsin law recognizes is essential for choosing the correct legal remedy.

What Is the Difference Between Annulment and Divorce in Wisconsin?
An annulment in Wisconsin legally erases a marriage as though it never existed, while a divorce terminates a valid marriage going forward. Under Wis. Stat. § 767.313, annulment requires proving specific legal defects that existed at the time of the marriage ceremony, such as fraud, bigamy, or mental incapacity. Wisconsin grants approximately 200-300 annulments per year compared to over 15,000 divorces, reflecting the difficulty of meeting annulment grounds.
The practical consequences differ significantly between these two legal remedies. Because an annulment declares the marriage void from inception, Wisconsin's community property division rules under Wis. Stat. § 767.61 do not automatically apply. Instead, property must be divided on an item-by-item basis based on actual ownership. In contrast, divorce proceedings begin with the presumption that all marital property will be divided equally (50/50) between the spouses.
Wisconsin courts can still order child support, child custody, visitation, and even spousal support in annulment cases when children are involved. The legal status of children born during an annulled marriage remains legitimate under Wisconsin law, protecting their inheritance and support rights. This protection ensures that children do not suffer legal consequences from their parents' invalid marriage.
Time constraints also distinguish these proceedings. Annulment petitions based on fraud, duress, or incapacity must be filed within one year of discovering the grounds. Divorce has no such limitation—you can file after any length of marriage. However, divorce requires the mandatory 120-day waiting period under Wis. Stat. § 767.335, while annulment has no waiting period once you prove valid grounds.
What Are the Legal Grounds for Annulment in Wisconsin?
Wisconsin Statute 767.313 recognizes five specific grounds for annulment: lack of capacity to consent, physical incapacity, underage marriage, bigamy, and marriage within six months of a prior Wisconsin divorce. Each ground requires substantial evidence, and courts rarely grant annulments without compelling proof. Simply regretting the marriage, having a short marriage, or discovering incompatibility does not qualify as annulment grounds under Wisconsin law.
Lack of Capacity to Consent
A marriage is voidable when either spouse lacked the mental capacity to consent at the time of the ceremony. This includes mental incapacity due to intellectual disability, mental illness, or the influence of alcohol or drugs. The intoxicated spouse must prove they were so impaired they could not understand the nature and consequences of the marriage ceremony. Merely being drunk is insufficient; complete incapacity to understand the marriage contract is required.
Fraud and duress also fall under this category. Fraud must involve the essentials of marriage—such as lying about the ability to have children, concealing a criminal history, or misrepresenting religious beliefs fundamental to the marriage decision. Ordinary lies about income, assets, or personal history typically do not qualify. Duress requires proof of threats or coercion that overcame the spouse's free will to marry.
Physical Incapacity (Impotence)
Wisconsin courts may annul a marriage when one spouse is physically incapable of consummating the marriage through sexual intercourse, provided the other spouse did not know about this condition at the time of marriage. The incapacity must be permanent and incurable, not temporary. The petitioning spouse must file within one year of discovering the physical incapacity.
Underage Marriage Without Proper Consent
Wisconsin law sets the marriage age at 18 without parental consent, or 16-17 with parental consent and court approval. Marriages involving parties under 16 are prohibited entirely. When a spouse was underage at the time of marriage without proper consent, either the underage party or a parent/guardian may seek annulment. The underage party may file anytime before turning 18; parents must file within one year of learning about the marriage.
Bigamy
If either spouse was already legally married to someone else at the time of the Wisconsin marriage ceremony, the subsequent marriage is void. Unlike other annulment grounds, there is no time limit for filing when bigamy is the basis—the petitioner may file at any time. The existence of a prior undissolved marriage automatically invalidates the later marriage regardless of whether either party knew about it.
Marriage Within Six Months of Prior Divorce
Under Wisconsin law, parties to a divorce action are prohibited from remarrying anywhere in the world for six months after the divorce judgment is entered. If a spouse remarries within this six-month period, the new marriage may be annulled. This ground must be raised within 10 years of the prohibited marriage.
What Are the Residency Requirements for Annulment vs Divorce in Wisconsin?
Divorce in Wisconsin requires at least one spouse to have been a bona fide resident of the state for a minimum of six months (180 days) immediately before filing under Wis. Stat. § 767.301. Additionally, at least one spouse must have resided in the filing county for at least 30 days before commencing the action. Annulment has a significantly lower threshold, requiring only 30 days of Wisconsin residency before filing.
| Requirement | Divorce | Annulment |
|---|---|---|
| State Residency | 6 months (180 days) | 30 days |
| County Residency | 30 days | Not specified |
| Waiting Period | 120 days mandatory | None |
| Time Limit to File | None | 1 year for most grounds |
The residency requirements are jurisdictional, meaning that filing before meeting them results in dismissal of the entire action. Courts cannot waive these requirements, and you cannot cure a residency deficiency by amending your petition—you must start over entirely. Acceptable proof of residency includes a Wisconsin driver's license, utility bills, voter registration, pay stubs from Wisconsin employers, or lease agreements for Wisconsin housing.
For military members stationed in Wisconsin, the six-month residency period typically begins when they establish Wisconsin as their legal domicile, not merely when they are assigned to a Wisconsin duty station. Military spouses stationed elsewhere may still file in Wisconsin if they can prove bona fide Wisconsin residency through intent to remain after military service.
How Long Does an Annulment Take Compared to Divorce in Wisconsin?
An uncontested annulment in Wisconsin typically takes 4-8 weeks from filing to final judgment because there is no mandatory waiting period. Contested annulments requiring a trial may take 6-12 months depending on the complexity of proving the grounds. Divorce proceedings require a minimum of 120 days (approximately 4 months) due to Wisconsin's mandatory waiting period, with contested divorces often taking 9-18 months to resolve.
The 120-day divorce waiting period under Wis. Stat. § 767.335 begins after the respondent is served with divorce papers, or after filing a joint petition if both spouses file together. This waiting period is among the longest in the United States, designed to encourage reconciliation. Courts can waive this period only for emergency reasons, such as when a domestic violence protection order is in place.
Annulment timelines depend heavily on whether the grounds can be proven. Straightforward bigamy cases with clear documentation may resolve quickly, while fraud or incapacity claims requiring witness testimony and expert evidence may take considerably longer. Both proceedings are faster when spouses agree on all issues including property division and any applicable support obligations.
How Does Property Division Differ Between Annulment and Divorce?
In Wisconsin divorce proceedings, all marital property is presumptively divided equally (50/50) between spouses under the state's community property laws codified in Wis. Stat. § 767.61. Annulment proceedings do not trigger this automatic equal division because the marriage is declared void from inception. Instead, property must be traced to its actual owner and divided on an item-by-item basis.
Wisconsin is one of only nine community property states in the United States. During divorce, nearly all property acquired during the marriage is considered marital property regardless of whose name appears on the title or who earned the income. Individual property (assets owned before marriage, gifts, and inheritances kept separate) remains with the original owner. Courts may deviate from the 50/50 presumption based on factors including marriage length, each spouse's age and health, contributions to the marriage, and earning capacity.
| Property Type | Divorce Treatment | Annulment Treatment |
|---|---|---|
| Home purchased during marriage | 50/50 presumption | Ownership traced to purchaser |
| Joint bank accounts | 50/50 presumption | Contributions traced |
| Retirement accounts earned during marriage | 50/50 presumption | Belongs to employee spouse |
| Inherited assets kept separate | Individual property | Individual property |
| Debts incurred during marriage | 50/50 presumption | Traced to debtor |
The practical effect of annulment on property can be significant. A spouse who contributed less financially during the marriage may receive substantially less in an annulment than they would in a divorce. Conversely, a spouse who brought significant assets into the marriage may preserve more of their wealth through annulment. Courts retain authority to order support and address property disputes even in annulment cases to prevent unjust outcomes.
What Happens to Children in an Annulment vs Divorce?
Children born during an annulled marriage retain their full legal rights under Wisconsin law, including legitimacy, custody rights, child support, and inheritance claims. Under Wis. Stat. § 767.313, courts can order custody, visitation schedules, and child support in annulment proceedings just as they would in divorce cases. The child support calculation follows the same percentage-of-income guidelines used in divorce: 17% for one child, 25% for two children, 29% for three, 31% for four, and 34% for five or more.
Custody determinations in both annulment and divorce proceedings focus on the best interests of the child under Wis. Stat. § 767.41. Factors include each parent's wishes, the child's wishes, the child's relationship with each parent and siblings, the child's adjustment to home and community, and the mental and physical health of all parties. Wisconsin courts strongly favor maintaining both parents' involvement in children's lives.
Parenting plans must address legal custody (decision-making authority) and physical placement (where the child lives). Wisconsin distinguishes between joint legal custody, where both parents share major decisions about health, education, and religion, and physical placement schedules that may range from equal placement (50/50) to primary placement with one parent and visitation with the other.
How Much Does Annulment Cost vs Divorce in Wisconsin?
The base filing fee for both annulment and divorce in Wisconsin is $184.50, increasing to $194.50 when the petition includes requests for child support or spousal maintenance. Milwaukee County charges slightly higher fees of $188-$198. E-filing adds a $20 convenience fee. Service of process costs $50-$100 when using a sheriff or private process server, though service by mail or acceptance of service eliminates this cost.
Total costs vary dramatically based on whether the case is contested. Uncontested annulments or divorces where spouses agree on all terms typically cost $700-$6,000 including attorney fees and court costs. Contested cases requiring litigation average $15,000-$30,000, with complex cases involving substantial assets, custody disputes, or business valuations potentially exceeding $50,000.
| Cost Component | Typical Range |
|---|---|
| Court filing fee | $184.50-$198 |
| Service of process | $0-$100 |
| Attorney retainer (uncontested) | $2,500-$5,000 |
| Attorney retainer (contested) | $5,000-$10,000 |
| Attorney hourly rate | $200-$450 |
| Mediation (if used) | $3,000-$7,000 |
| Guardian ad litem (custody cases) | $2,500-$7,500 |
| Total uncontested proceeding | $700-$6,000 |
| Total contested proceeding | $15,000-$30,000 |
Fee waivers are available for low-income petitioners earning at or below 125% of federal poverty guidelines. To request a waiver, file Form CV-410A (Petition for Waiver of Fees and Costs) with your petition. The court evaluates income, assets, and expenses to determine eligibility. As of March 2026, verify current fee amounts with your local circuit court clerk.
Can I Get an Annulment Instead of Divorce If My Marriage Was Short?
No, the length of marriage does not qualify as grounds for annulment in Wisconsin. Even marriages lasting only days or weeks require proof of one of the five statutory grounds under Wis. Stat. § 767.313: lack of capacity, physical incapacity, underage without consent, bigamy, or marriage within six months of a prior divorce. Many people mistakenly believe that a short marriage automatically qualifies for annulment, but this is a common misconception.
If you married recently and wish to end the marriage quickly but cannot prove annulment grounds, divorce remains your only option. The 120-day waiting period still applies regardless of marriage length. However, short marriages typically involve simpler property division since there has been less time to accumulate joint assets and debts. Courts may complete uncontested short-marriage divorces relatively efficiently once the waiting period expires.
The Catholic Church and other religious organizations may have different annulment standards that do not require proving civil annulment grounds. A religious annulment allows remarriage within that faith but has no effect on your legal marital status. You would still need either a civil annulment or divorce to legally end the marriage and remarry under Wisconsin law.
What Is the Time Limit for Filing an Annulment in Wisconsin?
Most annulment grounds in Wisconsin must be raised within one year of discovering the basis for annulment, with specific exceptions for bigamy and underage marriage. Under Wis. Stat. § 767.313, claims based on lack of capacity (including fraud, duress, mental incapacity, or intoxication) and physical incapacity must be filed no later than one year after the petitioner learned of the condition. Missing this deadline permanently bars the annulment claim.
Bigamy has no time limit whatsoever—you may seek annulment at any time if your spouse was already married when they married you. For marriages prohibited under other Wisconsin laws (such as incest), the time limit is 10 years from the marriage date. Underage marriage claims may be filed by the underage party anytime before turning 18, while parents or guardians must file within one year of learning about the marriage.
| Annulment Ground | Time Limit to File |
|---|---|
| Fraud, duress, or coercion | 1 year from discovery |
| Mental incapacity or intoxication | 1 year from discovery |
| Physical incapacity (impotence) | 1 year from discovery |
| Underage marriage (filed by minor) | Before turning 18 |
| Underage marriage (filed by parent) | 1 year from learning of marriage |
| Bigamy | No time limit |
| Marriage within 6 months of divorce | 10 years from marriage |
| Incest or other prohibited marriage | 10 years from marriage |
If you miss the applicable deadline, divorce becomes your only option to legally end the marriage. Courts strictly enforce these time limits and generally cannot extend them for equitable reasons. Consult with a Wisconsin family law attorney immediately if you believe you have grounds for annulment.
How Do I File for Annulment in Wisconsin?
Filing for annulment in Wisconsin requires preparing a Petition for Annulment, gathering evidence of your grounds, and filing with the circuit court in the county where you or your spouse resides. Unlike divorce, Wisconsin courts do not provide standardized forms for annulment proceedings. You must draft your own petition or hire an attorney to prepare the documents, as the legal requirements are more complex than standard divorce filings.
The petition must identify both parties, state the date and place of marriage, assert the specific statutory ground for annulment under Wis. Stat. § 767.313, and provide factual allegations supporting that ground. You must also address any children of the marriage and request appropriate custody and support orders. File the petition with the circuit court clerk along with the $184.50 filing fee and any required supporting documents.
After filing, you must serve your spouse with copies of all filed documents. Service may be accomplished through the county sheriff ($50-$75), a private process server ($50-$100), certified mail with return receipt, or voluntary acceptance of service (free). Once your spouse is served or accepts service, they have 20 days to file a response.
The court will schedule a hearing where you must present evidence proving your annulment grounds. Bring documents such as marriage certificates, medical records, police reports, witness statements, or other evidence relevant to your specific ground. The burden of proof rests entirely on the petitioner—you must convince the judge that your marriage meets the statutory requirements for annulment.
Frequently Asked Questions
Can I get an annulment if my spouse lied about their finances before marriage?
No, lying about finances, income, assets, or debts before marriage does not typically qualify as fraud for annulment purposes in Wisconsin. Under Wis. Stat. § 767.313, fraud must involve the essentials of marriage, such as the ability to have children, concealment of a criminal history, or misrepresentation of religious beliefs fundamental to the marriage decision. Financial deception, while ethically troubling, does not void the marriage itself.
How long after marriage can I file for annulment in Wisconsin?
The time limit depends on your specific ground. Claims based on fraud, duress, mental incapacity, intoxication, or physical incapacity must be filed within one year of discovering the ground. Bigamy claims have no time limit. Prohibited marriages (incest, remarriage within six months of divorce) must be challenged within 10 years. Underage parties may file before turning 18, while parents must file within one year of learning about the marriage.
Does an annulment affect my children's legitimacy in Wisconsin?
No, children born during an annulled marriage remain legitimate under Wisconsin law. They retain all legal rights including child support, custody arrangements, and inheritance claims. Courts can order custody, visitation, and support in annulment proceedings just as they would in divorce cases. The child support guidelines (17% for one child, 25% for two children, etc.) apply equally to annulment and divorce proceedings.
Will I receive alimony if my marriage is annulled?
Yes, Wisconsin courts retain authority to order spousal support (maintenance) in annulment cases despite the marriage being declared void. Under Wis. Stat. § 767.56, courts consider factors including marriage length, each spouse's age and health, property division, educational background, earning capacity, and contributions to the other spouse's education or career. However, annulment after a short marriage typically results in limited or no maintenance.
Is it easier to get an annulment or a divorce in Wisconsin?
Divorce is significantly easier to obtain in Wisconsin. As a no-fault divorce state under Wis. Stat. § 767.315, Wisconsin only requires one spouse to testify that the marriage is irretrievably broken. No specific grounds or proof of wrongdoing is needed. Annulment requires proving one of five narrow statutory grounds with substantial evidence—a much higher burden. Courts grant approximately 200-300 annulments compared to over 15,000 divorces annually.
Can I remarry immediately after an annulment in Wisconsin?
Yes, unlike divorce, there is no remarriage waiting period after an annulment in Wisconsin. Once the court enters the annulment judgment, you may legally remarry immediately. In contrast, divorce requires a mandatory six-month waiting period before either party may remarry anywhere in the world. Violating this remarriage prohibition after divorce can itself become grounds for annulling the subsequent marriage.
What if I was too drunk to consent to my marriage?
Intoxication at the time of the marriage ceremony may qualify as grounds for annulment under Wisconsin's lack of capacity provision. However, you must prove complete incapacity to understand the nature and consequences of the marriage—not merely that you were drunk. Courts require evidence that the intoxication was so severe that meaningful consent was impossible. You must file within one year of the wedding, not one year of becoming sober.
Do I need an attorney for an annulment in Wisconsin?
While not legally required, an attorney is strongly recommended for Wisconsin annulments. Unlike divorce, Wisconsin courts do not provide standardized annulment forms, requiring custom petition drafting. The legal burden of proving annulment grounds is substantially higher than no-fault divorce, and evidentiary requirements are complex. Attorney fees for uncontested annulments typically range from $2,500-$5,000, while contested cases may cost $10,000 or more.
