Kansas courts annul marriages that were void from the start, based on fraud, or the result of a mistake. Here’s how the process works.
In Kansas, a judge must annul a marriage if it is void because of incest or bigamy, or if the marriage was induced by fraud. Courts also have discretion to grant an annulment in other situations where canceling the marriage contract would be fair—such as when one spouse concealed something that would have changed the other’s decision to marry.
Annulment isn’t the same as divorce. A divorce ends a valid marriage. An annulment declares that no legal marriage ever existed. Here, we cover who qualifies for an annulment in Kansas, what a judge can order afterward, and how the filing process works.
What Are the Grounds for an Annulment in Kansas?
Kansas law presumes that marriages are valid, so courts require strong evidence before granting an annulment. In some cases, a judge is required to set aside the marriage. In others, the court has greater authority to decide, depending on the circumstances.
Mandatory Grounds for Annulment in Kansas
In Kansas, a judge must annul a marriage if it is void from the beginning or based on fraud. (Kan. Stat. § 23-2702 (2026).) A marriage is invalid from the moment it takes place if:
- the spouses are too closely related by blood (incest), or
- one spouse was already married to someone else (bigamy).
(Kan. Stat. § 23-2503 (2026); State v. Fitzgerald, 240 Kan. 187 (1986).)
To qualify as fraud, the deception must relate to a central issue in the marriage, such as a wife concealing at the time of marriage that she was pregnant by another man. Minor misrepresentations or ordinary dishonesty are not enough to justify annulment.
Discretionary Grounds for a Kansas Annulment
A judge can also grant an annulment in other troubling situations, such as when the marriage resulted from a mistake, a lack of knowledge of an important fact, or another reason that would justify canceling a marriage contract. (Kan. Stat. § 23-2702 (2026).) This might cover situations as varied as incurable impotence or getting married while drunk. Judges have discretion in this area; they will consider the law and the circumstances before deciding whether an annulment is warranted.
Whatever the grounds, the problem has to have existed when you married. For example, if a spouse develops a severe mental illness during the marriage, that’s not grounds for an annulment—but it could be sufficient reason for divorce. (Kan. Stat. § 23-2701(a)(3) (2026).)
Valid Kansas Marriages That Might Surprise You
There are a few situations where marriages you might expect to be invalid are recognized in Kansas:
- Underage marriages. Kansas allows some marriages involving minors. Clerks can’t issue marriage licenses to anyone younger than 16. But a judge can approve a marriage at age 15 in rare cases, and 16- and 17-year-olds can marry with parental consent. (Kan. Stat. § 23-2505(c) (2026).)
- Certain first-cousin marriages. A first-cousin marriage is valid in Kansas if it was valid in the state or country where it took place, as long as the couple did not leave Kansas just to avoid its laws. (In re Estate of Loughmiller, 229 Kan. 584 (1981).)
What Happens After a Kansas Annulment?
An annulment means you and your spouse were never legally married, and both of you return to single status. Kansas doesn't impose a waiting period before you can remarry.
Unlike some states, Kansas gives judges the same financial toolkit in an annulment that they have in a divorce. An annulment decree can include orders:
- equitably dividing the parties' property and debts
- requiring one party to pay maintenance (spousal support)
- setting child support
- allocating parental decision-making and adopting a parenting plan
- restoring or changing a party's name, and
- awarding costs and attorney's fees.
(Kan. Stat. § 23-2711 (2026).)
Children of an annulled marriage keep their legal parentage. A man is presumed to be the father when the child is born during the marriage or within 300 days after the annulment decree is filed. (Kan. Stat. §§ 23-2206, 23-2208(a) (2026).)
How Do I Get an Annulment in Kansas?
Kansas doesn't make you live in the state for a set period before filing for an annulment. The 60-day residency rule applies to divorce, not annulment. (Kan. Stat. § 23-2703(a) (2026).) You can file in the county where you or your spouse lives or, if you’re stationed at a military post in Kansas, in any neighboring county. (Kan. Stat. § 60-607 (2026).)
To proceed, you must:
- File a “petition for annulment.” You’ll file in the local district court, providing all required information and stating the grounds for the annulment. If you need temporary support for yourself or any children, you should include that, too. Ask the clerk at the district court if they have a sample petition for annulment that you can use.
- Notify your spouse. You must officially deliver notice of the annulment case to your spouse—a step known as “service of process.” The court clerk can explain your options, including how to serve a spouse who lives out of state.
- Prove your case at a hearing. Your spouse can respond to your petition and can also request an annulment, divorce, or separate maintenance. If the court finds there are valid grounds, it will grant the decree.
(Kan. Stat. §§ 23-2704, 23-2705, 23-2706 (2026).)
The burden of proving the grounds for annulment falls on the spouse who files. And remember, Kansas judges scrutinize these requests carefully because the law presumes marriages are valid. Because property division and support can ride on the result, it's worth consulting a lawyer before you file.
