Wisconsin abolished common law marriage in 1917 under Wis. Stat. § 765.01, making it impossible to form a common law marriage within the state regardless of how long a couple lives together or presents themselves as married. However, Wisconsin courts recognize valid common law marriages established in other states such as Colorado, Texas, or Iowa under the full faith and credit doctrine. Couples who formed valid common law marriages elsewhere must divorce through Wisconsin courts using the standard divorce process, which requires a $184.50 filing fee, a 120-day waiting period, and compliance with the 6-month state residency requirement under Wis. Stat. § 767.301. Unmarried cohabiting couples who never established a valid common law marriage may pursue property claims through Watts actions, a civil remedy established by the Wisconsin Supreme Court in 1987.

Why Wisconsin Does Not Recognize Common Law Marriage
Wisconsin eliminated common law marriage recognition in 1917 under Wis. Stat. § 765.01, making formal marriage licensing mandatory for all marriages formed within the state. No matter how long an unmarried couple lives together in Wisconsin, shares finances, purchases property jointly, or presents themselves publicly as married, Wisconsin law does not consider them legally married without a valid marriage license and ceremony. This means that approximately 7.5% of Wisconsin households that include unmarried cohabiting partners have no marital rights under state law unless they formalized their relationship or established a common law marriage in another jurisdiction before moving to Wisconsin.
The distinction matters significantly for property rights, inheritance, healthcare decisions, and spousal benefits. Married couples in Wisconsin benefit from community property protections under Wis. Stat. § 766, which presumes equal ownership of assets acquired during marriage. Unmarried couples receive no such protection; assets belong to whichever partner holds title, regardless of joint contributions during the relationship.
Wisconsin is one of the majority of states that has abolished common law marriage. Currently, only seven states plus the District of Columbia allow new common law marriages to be formed: Colorado, Iowa, Kansas, Montana, New Hampshire (limited to inheritance purposes), Texas, and Utah. Six additional states recognize common law marriages formed before specific cutoff dates.
Divorcing an Out-of-State Common Law Marriage in Wisconsin
Wisconsin recognizes valid common law marriages established in states where such marriages are legal, and couples seeking to end these relationships must pursue formal divorce proceedings through Wisconsin courts. The principle of comity requires Wisconsin to honor marriages validly formed in other jurisdictions, even when Wisconsin law would not permit such a marriage to be formed locally.
To divorce a common law marriage in Wisconsin, you must first prove that your common law marriage is valid under the laws of the state where it was formed. Each state has different requirements for establishing common law marriage. In Texas, couples must agree to be married, live together in Texas, and represent to others that they are married under Texas Family Code Sections 2.401 through 2.405. In Colorado, couples must cohabit and mutually agree to be married while holding themselves out publicly as spouses. In Iowa, courts require present intent to marry, public declaration of marriage, continuous cohabitation, and legal capacity to marry.
Proving Your Out-of-State Common Law Marriage
Wisconsin courts will require evidence that your relationship met the legal requirements for common law marriage in the state where it was formed. Acceptable evidence includes:
- Joint tax returns filed as married filing jointly
- Insurance policies listing your partner as spouse
- Beneficiary designations naming your partner as spouse
- Joint bank accounts or credit cards
- Shared property deeds or mortgages
- Affidavits from family and friends confirming your marital reputation
- Children's birth certificates listing both partners as parents
- Medical records showing spousal consent authorizations
Once you establish the validity of your common law marriage, Wisconsin treats your divorce identically to any other divorce proceeding. You file a Summons and Petition for Divorce in the circuit court of the county where either spouse has resided for at least 30 days. The filing fee is $184.50 for divorces without minor children or maintenance requests, or $194.50 when children or spousal maintenance is involved. You must meet the 6-month state residency requirement under Wis. Stat. § 767.301 before filing.
Wisconsin Divorce Requirements for Common Law Marriages
Wisconsin applies identical procedural requirements to common law marriage divorces as it does to ceremonial marriage divorces. Understanding these requirements helps ensure your divorce proceeds smoothly and avoids jurisdictional dismissal.
Residency Requirements
Under Wis. Stat. § 767.301, at least one spouse must have been a bona fide resident of Wisconsin for at least 6 months immediately before filing for divorce. Additionally, at least one spouse must have lived in the filing county for at least 30 days before commencing the action. These requirements are jurisdictional, meaning that filing prematurely results in dismissal of the entire case, as established in Siemering v. Siemering, 95 Wis. 2d 111 (Ct. App. 1980). You cannot amend a prematurely filed petition; you must refile entirely after meeting the residency period.
Grounds for Divorce
Wisconsin is exclusively a no-fault divorce state. Under Wis. Stat. § 767.315, the sole ground for divorce is that the marriage is irretrievably broken. Courts do not consider fault-based allegations such as adultery, abandonment, or cruelty when granting divorce or dividing property. If both spouses state under oath that the marriage is irretrievably broken, the court must find that grounds exist. If only one spouse claims the marriage is broken, the court considers all relevant factors and may order a 30 to 60-day continuance to explore reconciliation.
Mandatory Waiting Period
Wisconsin mandates a 120-day waiting period between service of the divorce petition on the respondent spouse and entry of the final divorce judgment. This waiting period cannot be waived except in emergency circumstances, such as when a domestic abuse restraining order has been filed. The 120-day period gives couples time to consider reconciliation and allows both parties to gather financial information for property division.
Property Division in Common Law Marriage Divorces
Wisconsin is one of only nine community property states in the United States, alongside Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, and Washington. Under Wis. Stat. § 767.61, courts begin with a presumption that all marital property should be divided equally (50/50) between the spouses, regardless of whose name appears on the title or who earned the income.
The community property presumption applies to valid common law marriages the same way it applies to ceremonial marriages. Property acquired during your common law marriage while residing in a community property state or after moving to Wisconsin is presumed to be marital property subject to equal division. Separate property, such as assets owned before the common law marriage or received as gifts or inheritance from third parties, generally remains with the original owner unless it has been commingled with marital assets.
Factors for Unequal Division
Wisconsin courts may deviate from the 50/50 presumption when statutory factors justify an unequal split, potentially resulting in 60/40, 70/30, or other distributions. Under Wis. Stat. § 767.61(3), these factors include:
- Length of the marriage
- Property brought to the marriage by each party
- Whether one spouse has substantial separate assets
- Contribution to the marriage, including homemaking and child-rearing
- Age and physical and emotional health of each party
- Contribution to the education or increased earning power of the other spouse
- Earning capacity of each party
- Desirability of awarding the family home to the custodial parent
- Amount and duration of spousal maintenance
- Other economic circumstances, including pension benefits
- Tax consequences of property division
Marital misconduct is not a factor in property division because Wisconsin is a no-fault state. Courts divide property based on equitable principles rather than punishing perceived wrongdoing.
Watts Actions: Property Claims for Unmarried Wisconsin Couples
When unmarried couples who never established a valid common law marriage separate in Wisconsin, they cannot divorce because Wisconsin law does not recognize them as married. However, the Wisconsin Supreme Court established an alternative remedy in Watts v. Watts, 137 Wis. 2d 506, 405 N.W.2d 303 (1987), allowing cohabiting partners to pursue civil claims for property accumulated during their relationship.
Watts cases are civil actions based on contract law theories rather than family law. The most commonly invoked cause of action is unjust enrichment, which allows one former partner to recover an interest in assets titled in the other partner's name when retention of those assets would be inequitable. Courts examine the couple's intentions, conduct, and any express or implied agreements regarding property ownership during the relationship.
Legal Theories Available in Watts Actions
Unmarried couples separating in Wisconsin may pursue several legal theories:
- Unjust Enrichment: Recovery when one partner unfairly retains property acquired through the joint efforts of both partners
- Breach of Express Contract: Enforcement of explicit agreements about property ownership or sharing
- Breach of Implied Contract: Enforcement of agreements implied by the parties' conduct
- Partition: Division of jointly-owned real property
- Constructive Trust: Imposition of trust obligations when one partner holds property that equitably belongs to both
Key Differences Between Watts Actions and Divorce
| Issue | Divorce | Watts Action |
|---|---|---|
| Legal Basis | Family Code (Chapter 767) | Contract Law |
| Property Presumption | 50/50 community property split | No presumption; must prove contributions |
| Spousal Maintenance | Available | Not available |
| Child Custody | Addressed in divorce | Separate paternity/custody action required |
| Child Support | Addressed in divorce | Separate paternity action required |
| Filing Fee | $184.50-$194.50 | Standard civil filing fee (varies) |
| Court | Family Court | Civil Court |
| Burden of Proof | Presumption favors equal division | Claimant must prove unjust enrichment |
Watts actions require the claiming partner to prove specific contributions that led to an increase in wealth or property. Unlike divorce, where the 50/50 presumption places the burden on the party seeking deviation, Watts claimants must demonstrate that they contributed to property acquisition and that allowing the titled partner to retain all benefit would be unjust.
Protecting Your Rights as an Unmarried Couple in Wisconsin
Because Wisconsin does not recognize common law marriage, unmarried couples should take proactive steps to protect their property rights and document their intentions. A cohabitation agreement is a legally enforceable contract that sets forth each partner's rights and responsibilities regarding property ownership, debt allocation, living expenses, and property division upon separation.
Cohabitation agreements can prevent costly Watts litigation by clearly establishing each partner's ownership interests from the outset. The agreement should address:
- Ownership of property acquired during cohabitation
- Responsibility for household expenses and debts
- Division of property if the relationship ends
- Dispute resolution procedures
- Healthcare decision-making authority
- Estate planning considerations
Without a cohabitation agreement, Wisconsin law treats each partner's income and assets as that individual's separate property. If you purchase a home together but only one partner appears on the title, the titled partner owns the home absent proof of an agreement or unjust enrichment.

Frequently Asked Questions
Does Wisconsin recognize common law marriage?
No, Wisconsin abolished common law marriage in 1917 under Wis. Stat. § 765.01. Couples cannot form a common law marriage in Wisconsin regardless of how long they live together. However, Wisconsin recognizes valid common law marriages formed in other states where such marriages are legal, including Colorado, Texas, Iowa, Kansas, Montana, Utah, and the District of Columbia.
How do I prove my out-of-state common law marriage is valid in Wisconsin?
You must provide evidence that your relationship met the legal requirements for common law marriage in the state where it was formed. Wisconsin courts accept joint tax returns filed as married, insurance policies listing your partner as spouse, joint property deeds, affidavits from witnesses, and other documentation showing mutual agreement to be married and public reputation as a married couple.
What is a Watts action in Wisconsin?
A Watts action is a civil lawsuit allowing unmarried cohabiting partners to recover property interests when their relationship ends. Based on the 1987 Wisconsin Supreme Court case Watts v. Watts, these actions use contract law theories such as unjust enrichment rather than family law. Watts actions can address property division but cannot award spousal maintenance or establish child custody.
How long does a common law divorce take in Wisconsin?
A common law marriage divorce in Wisconsin takes a minimum of 120 days due to the mandatory waiting period under Wis. Stat. § 767.12. Uncontested divorces typically finalize in 4 to 6 months, while contested cases may take 12 to 18 months or longer depending on the complexity of property division and custody issues.
Can I get spousal maintenance from a common law marriage divorce in Wisconsin?
Yes, if your common law marriage is recognized as valid, you have the same right to spousal maintenance (alimony) as any divorced spouse in Wisconsin. Courts consider factors including the length of marriage, earning capacity of each spouse, educational level, age and health, and contributions to the marriage when determining maintenance awards under Wis. Stat. § 767.56.
What are my property rights as an unmarried partner in Wisconsin?
Unmarried partners in Wisconsin have limited property rights because the state does not recognize common law marriage. Assets and income acquired during cohabitation are treated as individual property belonging to the titled or earning partner. Partners seeking a share of jointly-accumulated property must file a Watts action proving unjust enrichment, breach of contract, or another civil claim.
How much does it cost to divorce a common law marriage in Wisconsin?
The filing fee for divorce in Wisconsin is $184.50 for cases without minor children, or $194.50 when children or spousal maintenance is involved. Total costs range from $700 to $6,000 for uncontested divorces and $15,000 to $30,000 for contested cases. Wisconsin attorneys charge $200 to $450 per hour with a median rate of $310.
Can I file for divorce if my spouse refuses to acknowledge our common law marriage?
Yes, you can file for divorce and present evidence to the court proving your common law marriage is valid under the laws of the state where it was formed. The court will determine whether sufficient evidence exists to recognize your marriage. If the court finds your common law marriage valid, your spouse's denial does not prevent the divorce from proceeding.
What if we lived in multiple states during our common law relationship?
The key question is whether you established a valid common law marriage in a state that recognizes such marriages. If you lived together in Colorado, Texas, or another common law marriage state and met that state's requirements for common law marriage formation, Wisconsin will recognize your marriage even if you later moved to Wisconsin or other non-recognizing states.
Should I get a cohabitation agreement if I live with my partner in Wisconsin?
Yes, a cohabitation agreement is strongly recommended for unmarried couples in Wisconsin. Because Wisconsin does not recognize common law marriage, unmarried partners have no automatic property rights when their relationship ends. A cohabitation agreement can specify property ownership, debt responsibility, and division procedures, potentially avoiding costly Watts litigation.
