Kansas is one of only seven states that still recognizes common law marriage in 2026, meaning couples who meet specific legal requirements are considered legally married without a formal ceremony or marriage license. Under K.S.A. § 23-2502, a common law marriage in Kansas requires three elements: capacity to marry, present mutual agreement to be married, and public representation as spouses. Dissolving a common law marriage in Kansas requires the same formal divorce process as ending a ceremonial marriage, including the $195 filing fee, 60-day residency requirement, and 60-day waiting period after filing. The Kansas Supreme Court established these standards in In re Estate of Antonopoulos, 268 Kan. 178 (1999), which remains the controlling authority on common law marriage proof requirements.

What Is a Common Law Marriage in Kansas?
A common law marriage in Kansas is a legally binding marriage created without a formal ceremony or marriage license when both parties meet three statutory requirements under K.S.A. § 23-2502. Kansas courts require proof of capacity to marry, present mutual agreement to be married, and consistent public representation as a married couple. Under this statute, Kansas will not recognize a common law marriage if either party is under 18 years of age, establishing a clear minimum age requirement. Common law marriages formed in Kansas receive identical legal treatment to ceremonial marriages, including the same divorce procedures, property division rules, and spousal maintenance eligibility.
The Kansas Supreme Court case In re Estate of Antonopoulos, 268 Kan. 178 (1999) established the evidentiary standards that Kansas courts apply when determining whether a common law marriage exists. In Antonopoulos, the court found that a common law marriage predated the couple's July 1992 marriage ceremony, extending the marriage length to 10 years and establishing the surviving spouse's elective share at 30 percent of the augmented estate. This case demonstrates how courts retrospectively evaluate evidence of mutual consent and public representation, often relying on financial records, shared property ownership, and testimony from family and community members.
The Three Elements Required to Prove a Common Law Marriage
Establishing a common law marriage in Kansas requires proving three distinct elements, with the burden of proof falling on the party asserting the marriage exists. Kansas courts apply a preponderance of the evidence standard, meaning you must demonstrate it is more likely than not that all three elements were satisfied during your relationship. Without formal documentation like a marriage license, couples must present circumstantial evidence including shared bank accounts, joint property deeds, tax returns filed as married, and witness testimony from family members and neighbors who understood the couple to be married.
Element 1: Capacity to Marry
Both parties must have legal capacity to enter into marriage under K.S.A. § 23-2501, which requires being at least 18 years old, not being married to another person, and not being closely related by blood. Mental capacity to understand the nature of marriage is also required, meaning both parties must be able to comprehend that they are entering a legal relationship with rights and obligations. Kansas courts will invalidate a common law marriage if one party was already legally married to someone else at the time the alleged common law marriage began, as bigamous marriages are void under Kansas law.
Element 2: Present Mutual Agreement to Marry
Kansas law requires proof that both parties had a present intent to be married, not merely a promise to marry in the future. This element is often the most difficult to prove because it requires demonstrating the subjective mental state of both parties. Kansas courts examine evidence such as shared finances, joint ownership of property, using a shared surname, and statements made to others indicating married status. The Kansas Court of Appeals emphasized in Driscoll v. Driscoll that mere cohabitation alone is insufficient; the parties must demonstrate a mutual understanding that they are entering into a marriage relationship.
Element 3: Public Representation as Married
The couple must hold themselves out to the community as husband and wife, creating a general reputation as a married couple among family, friends, neighbors, and business associates. Evidence supporting this element includes filing joint tax returns, listing each other as spouses on insurance forms, introducing each other as husband or wife, using the same last name, and wearing wedding rings. The public representation must be consistent and unequivocal throughout the relationship. Kansas courts consider whether reasonable community members would believe the couple to be married based on their behavior and representations.
How to File for Divorce From a Common Law Marriage in Kansas
Divorcing from a common law marriage in Kansas follows the identical process as divorcing from a ceremonial marriage, with one critical additional step: you must first prove the common law marriage exists. The divorce filing fee is $195 in most Kansas district courts, with some counties adding small surcharges bringing the total to approximately $190-$200 as of March 2026. Before filing, at least one spouse must have been an actual resident of Kansas for a minimum of 60 days immediately preceding the filing of the petition under K.S.A. § 23-2703.
Kansas imposes a 60-day waiting period under K.S.A. § 23-2708, meaning the court cannot hold a final divorce hearing until 60 days after the petition is filed. This cooling-off period applies to both contested and uncontested divorces. An uncontested common law divorce where both parties agree on all terms typically costs $245-$500 total including filing fees, service of process ($15-$75), and certified copies ($1 per page). Contested divorces requiring attorney representation average $7,500-$15,000 per spouse in Kansas.
Step-by-Step Filing Process
- Gather evidence proving the common law marriage exists (joint accounts, tax returns, witness statements)
- Meet the 60-day Kansas residency requirement
- File the Petition for Divorce in the district court of the county where either spouse resides
- Pay the $195 filing fee or file an Application to Proceed Without Payment if income is below 125% federal poverty level (approximately $17,400 for single person in 2026)
- Serve the other spouse with divorce papers through sheriff, process server, or certified mail
- Wait the mandatory 60-day cooling-off period
- If uncontested, submit a settlement agreement; if contested, proceed to trial
- Attend the final hearing where the court will first confirm the common law marriage existed before granting the divorce
Property Division in Common Law Marriage Divorce
Kansas applies equitable distribution principles under K.S.A. § 23-2802 to divide property in all divorces, including common law marriage divorces. Kansas follows an all-property model, meaning once a divorce is filed, virtually all property owned by either spouse becomes part of the marital estate subject to division, including assets acquired before the marriage or received by inheritance. This comprehensive approach distinguishes Kansas from states that protect separate property; in Kansas, the court has authority to divide everything the couple owns regardless of when or how it was acquired.
The statute provides three methods for property division: division of property in kind between the spouses, awarding property to one spouse while requiring payment to the other, or ordering a sale with proceeds divided according to court order. Kansas courts aim for fair and just division rather than automatic 50/50 splits, considering all circumstances of the marriage and each spouse's situation.
The Ten Statutory Factors Under K.S.A. 23-2802(c)
Kansas courts must consider ten specific factors when dividing property:
- The age of the parties
- The duration of the marriage (calculated from when common law marriage elements were first satisfied)
- The property owned by the parties
- Their present and future earning capacities
- The time, source, and manner of acquisition of property
- Family ties and obligations
- Whether maintenance (alimony) is awarded
- Dissipation of assets by either party
- Tax consequences of the property division
- Other factors the court considers necessary for just division
For common law marriages, accurately determining the marriage duration is critical because it affects both property division and potential spousal maintenance awards. Courts examine when all three elements of common law marriage were first satisfied, which may be years before the couple began living together if they had capacity, agreement, and public representation from an earlier date.
Spousal Maintenance in Common Law Divorce
Kansas spousal maintenance (alimony) in common law divorces follows the same standards as ceremonial marriage divorces under K.S.A. § 23-2902. The statute caps all maintenance awards at 121 months (approximately 10 years and 1 month) unless both parties agree otherwise in writing, making permanent alimony extremely rare in Kansas. Courts may grant one additional 121-month reinstatement period if the original decree reserved that power and the recipient files a motion before the initial period expires, potentially extending support to a maximum of 20 years.
Kansas courts have broad discretion to determine maintenance amounts, guided by the statutory requirement that awards be fair, just, and equitable under all circumstances. While there is no mandatory formula, the Johnson County Bar Association guidelines are widely used across Kansas, calculating maintenance at 20-25% of the difference in monthly gross incomes with duration tied to marriage length. For marriages lasting less than five years, duration equals marriage length divided by 2.5. For longer marriages, duration equals 2 years plus one-third of the marriage length.
Factors Courts Consider for Maintenance
Under K.S.A. § 23-2902, Kansas courts evaluate multiple factors including:
- Present and future earning capacity of both spouses
- The marital standard of living
- Length of the marriage (from when common law marriage began)
- Age and health of both parties
- Time needed for recipient to become self-supporting
- Financial resources of each spouse
- Contributions to the marriage (including homemaking and childcare)
- The paying spouse's ability to meet their own needs while paying support
Maintenance can be modified under K.S.A. § 23-2903 when either spouse demonstrates a material change in circumstances since the last order, such as job loss, significant income change, or serious illness.
Child Custody in Common Law Marriage Divorce
Children born during a common law marriage have identical legal status to children born during ceremonial marriages, entitled to the same custody determinations, child support, and inheritance rights. Kansas courts apply the best interest of the child standard under K.S.A. § 23-3203 when determining custody arrangements. There is no presumption favoring mothers over fathers; Kansas law explicitly requires judges to consider all relevant evidence without gender bias under K.S.A. § 23-3204.
Kansas requires divorcing parents to submit a parenting plan addressing legal custody (decision-making authority), physical custody (where the child lives), and a parenting time schedule. Under K.S.A. § 23-3202, if parents agree on a parenting plan, the court presumes the agreement serves the child's best interests. If parents cannot agree, the court will create a custody plan after evaluating all statutory factors. Parents in divorces involving children typically must complete a parenting education class costing $20-$50 per parent.
Best Interest Factors Under K.S.A. 23-3203
Kansas courts evaluate numerous factors when determining custody arrangements:
- The child's relationship with each parent, siblings, and household members
- The child's adjustment to home, school, and community
- Each parent's ability to cooperate and communicate about parenting
- Each parent's involvement with the child before separation
- The desires of a child of sufficient age and maturity
- Evidence of domestic abuse or child abuse
- Whether either parent is a registered sex offender
- Each parent's willingness to respect the child's relationship with the other parent
Under K.S.A. § 23-3222, either parent must provide notice before relocating with a child, with specific requirements for interstate moves that could affect the parenting schedule.
Proving Common Law Marriage When Your Spouse Denies It
When one party denies that a common law marriage exists, the burden falls entirely on the party claiming the marriage to prove all three elements by a preponderance of the evidence. This situation commonly arises when the relationship ends and one party wants to avoid property division, maintenance, or inheritance obligations. Kansas courts conduct a thorough evidentiary hearing to determine whether the marriage elements were satisfied, examining documentary evidence and witness testimony.
Strong evidence for proving a common law marriage includes joint federal and state tax returns filed as married filing jointly (which creates potential perjury liability if the marriage did not exist), joint bank accounts and credit cards listing both parties as account holders, real estate deeds showing both parties as married owners, life insurance or retirement beneficiary designations listing the other as spouse, employer health insurance coverage for the other as spouse, and testimony from family members, neighbors, or colleagues who understood the parties to be married.
Common Defenses Against Common Law Marriage Claims
The party denying the marriage may argue that capacity was lacking (one party was already married or under 18), there was no present agreement to be married (only an agreement to marry in the future or live together), or that the couple never held themselves out as married despite cohabitation. Evidence supporting these defenses includes maintaining separate finances, filing taxes as single, introducing the other as boyfriend or girlfriend rather than spouse, and testimony from witnesses who understood the parties were not married.
Common Law Marriage Recognition Across State Lines
If you established a valid common law marriage in Kansas and later move to another state, your marriage should be recognized under the Full Faith and Credit Clause of the U.S. Constitution. This means you would need to obtain a formal divorce even in a state like California that does not allow new common law marriages to be formed. As of 2026, only seven states plus the District of Columbia still recognize new common law marriages: Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, and Utah (with additional requirements). Six other states recognize common law marriages formed before a specific cutoff date.
Conversely, if you formed a valid common law marriage in another state and now reside in Kansas, you can file for divorce in Kansas after meeting the 60-day residency requirement. Kansas courts will recognize your out-of-state common law marriage and apply Kansas divorce law to dissolve it. Military personnel stationed in Kansas for at least 60 days at a U.S. military post may file for divorce in any county adjacent to the installation under K.S.A. § 23-2703(b).
Cost of Common Law Marriage Divorce in Kansas
The total cost of divorcing from a common law marriage in Kansas ranges from approximately $245 for a simple DIY uncontested divorce to $25,000 or more for highly contested cases requiring extensive litigation. The base filing fee of $195 applies regardless of whether your marriage was ceremonial or common law. However, common law divorces may incur additional costs if the existence of the marriage itself is disputed, as this requires a preliminary evidentiary hearing with potentially extensive documentation and witness testimony.
Cost Breakdown by Divorce Type
| Divorce Type | Estimated Total Cost | Timeline |
|---|---|---|
| DIY Uncontested | $245 - $500 | 60-90 days |
| Mediated Uncontested | $1,500 - $3,500 | 90-120 days |
| Attorney-Assisted Uncontested | $2,500 - $5,000 | 60-120 days |
| Contested (no trial) | $7,500 - $15,000 | 6-12 months |
| Contested (with trial) | $15,000 - $25,000+ | 12-24 months |
| Contested with marriage dispute | $20,000 - $35,000+ | 12-30 months |
Individuals earning below 125% of the federal poverty level (approximately $17,400 for a single person or $23,500 for a family of two in 2026) may qualify for fee waivers by filing an Application to Proceed Without Payment. Kansas courts grant fee waivers to individuals demonstrating financial hardship.
Frequently Asked Questions
How long do you have to live together in Kansas to have a common law marriage?
Kansas has no minimum cohabitation period to establish a common law marriage. The three required elements are capacity to marry, present mutual agreement to be married, and public representation as spouses under K.S.A. § 23-2502. A couple could theoretically satisfy all three elements on a single day if they have capacity, mutually agree to be presently married, and begin holding themselves out as married to the community. However, courts are skeptical of claims involving very short periods without substantial corroborating evidence.
Can I just walk away from a common law marriage in Kansas?
No, you cannot simply walk away from a valid common law marriage. Under Kansas law, a common law marriage has the same legal status as a ceremonial marriage and can only be dissolved through formal divorce proceedings or death of a spouse. Walking away without divorce leaves both parties legally married, unable to remarry without committing bigamy, and potentially liable for the other spouse's debts. You must file for divorce in Kansas district court, pay the $195 filing fee, and complete the 60-day waiting period.
Do common law spouses have inheritance rights in Kansas?
Yes, common law spouses have identical inheritance rights to ceremonially married spouses in Kansas. If one spouse dies without a will, the surviving common law spouse inherits under Kansas intestacy laws. The surviving spouse may also claim an elective share of the augmented estate, as demonstrated in In re Estate of Antonopoulos where the court awarded the common law spouse 30% of the augmented estate. Proving the common law marriage existed becomes crucial in estate disputes, as seen in that case where the marriage predated the formal ceremony.
What if my common law spouse denies we were married?
The burden of proving a common law marriage falls on the party claiming it exists. You must present evidence demonstrating all three elements: capacity, present agreement, and public representation. Strong evidence includes joint tax returns filed as married, joint bank accounts, property deeds listing both as married, health insurance coverage as spouse, and testimony from people who understood you to be married. Kansas courts will hold an evidentiary hearing to determine whether the marriage elements were satisfied before proceeding with divorce.
Is property divided differently in common law divorce?
No, Kansas applies the same equitable distribution rules under K.S.A. § 23-2802 to common law divorces as ceremonial divorces. Under Kansas's all-property model, all assets owned by either spouse become part of the marital estate subject to division, including property acquired before the marriage or inherited. The court considers ten statutory factors to achieve fair division. However, determining when the marriage began may be more complex in common law divorces, affecting how property acquired during contested periods is treated.
Can I get alimony from a common law marriage divorce?
Yes, spousal maintenance eligibility is identical for common law and ceremonial marriages under K.S.A. § 23-2902. Courts consider factors including earning capacity, marital standard of living, marriage duration, and time needed for self-sufficiency. Kansas caps maintenance at 121 months unless both parties agree otherwise. The Johnson County guidelines suggest calculating maintenance at 20-25% of the income difference between spouses, with duration based on marriage length. Marriage duration is calculated from when all common law marriage elements were first satisfied.
Do children have different rights in common law marriage divorce?
No, children born during a common law marriage have identical legal rights to children born during ceremonial marriages. Kansas courts apply the same best interest standard under K.S.A. § 23-3203 for custody determinations. Both parents have equal standing to seek custody regardless of the marriage type. Child support calculations follow the Kansas Child Support Guidelines without variation for common law marriages. The only additional issue is that establishing the common law marriage may be necessary to confirm presumed paternity.
How do I prove the date my common law marriage began?
Proving when a common law marriage began requires documenting when all three elements were first satisfied simultaneously. Key evidence includes the earliest joint tax return filed as married, the first joint bank account or property purchase as a married couple, dated correspondence referring to each other as spouse, wedding announcements or parties even without formal ceremony, and testimony from witnesses about when the couple began representing themselves as married. Courts will examine when capacity, agreement, and public holding out first converged.
Will Kansas recognize my common law marriage from another state?
Yes, Kansas recognizes valid common law marriages formed in other states under the Full Faith and Credit Clause. If you established a common law marriage in Colorado, Iowa, Texas, Montana, Oklahoma, Rhode Island, Utah, or the District of Columbia, Kansas will treat it as a valid marriage. You can file for divorce in Kansas after meeting the 60-day residency requirement. You may need to prove the marriage satisfied the other state's specific requirements, which may differ slightly from Kansas law.
What happens if one common law spouse dies before divorce is final?
If a common law spouse dies during pending divorce proceedings, the surviving spouse retains inheritance rights until the divorce is finalized. The divorce action terminates upon death, and the survivor may claim their statutory share of the estate. As shown in In re Estate of Antonopoulos, establishing the existence and duration of the common law marriage becomes critical for calculating the surviving spouse's elective share percentage, which ranges from 3% to 50% based on marriage length under Kansas law.
