Kansas transgender laws define sex as biological sex at birth throughout state government, restrict gender-affirming medical care for anyone under 18, require school and college sports teams to be separated by biological sex, and close most pathways to change a sex marker on a birth certificate. Driver’s license gender markers can still be updated after a 2025 court ruling, legal name changes work the same for everyone, and federal employment protections under Title VII still apply to Kansas workers. The details below walk through each area so you can see what applies to your situation.
How Kansas Defines Sex
Senate Bill 180, called the Women’s Bill of Rights, passed over the governor’s veto on April 27, 2023, and took effect July 1, 2023. It added K.S.A. 77-207, which controls how the word “sex” is read in every Kansas statute and regulation. Sex means biological sex at birth. A female is a person whose reproductive system is developed to produce ova; a male is a person whose reproductive system is developed to fertilize ova.1Kansas Office of Revisor of Statutes. Kansas Code 77-207 – Biological Sex; Application Thereof to Any State Law
The statute also says “equal” does not mean “same or identical” when applied to biological sex, and that separate accommodations by sex are not inherently unequal. Every state agency, school district, and political subdivision that collects vital statistics for anti-discrimination compliance or public health must record each person as male or female at birth.1Kansas Office of Revisor of Statutes. Kansas Code 77-207 – Biological Sex; Application Thereof to Any State Law This definitional rule is the engine behind the specific restrictions that follow.
Driver’s License Gender Markers
Transgender Kansans can update the gender marker on a Kansas driver’s license. Attorney General Kris Kobach sued in 2023 to block the Department of Revenue from processing those changes under SB 180, and a Shawnee County judge initially entered a temporary injunction. In June 2025, the Kansas Court of Appeals overturned that injunction, and the Kansas Supreme Court declined to take the case. As of October 2025, the Department of Revenue is again processing gender marker updates on licenses.2State Court Report. Supreme Court of Kansas – Order Denying Petition
The underlying statute, K.S.A. 8-243, requires licenses to display the holder’s gender, which the courts have so far allowed the agency to administer independently of the SB 180 biological-sex rule.3Kansas Office of Revisor of Statutes. Kansas Code 8-243 – Issuance of Licenses; Contents
Birth Certificates
Birth certificates are a different matter. Kansas no longer updates the sex marker on a birth certificate to reflect a gender transition. A 2019 federal consent judgment that had allowed those updates was reopened in September 2023 after SB 180 passed, and the current state regulation, K.A.R. 28-17-20, permits the sex field to be amended only if the original recording was factually incorrect, backed by medical records from the time of birth.4Legal Information Institute. Kansas Administrative Regulations 28-17-20 – Corrections to Certificates and Records In practice, that covers a clerical error at the hospital, not a transition years later.
You can still get a new birth certificate issued after a court-ordered name change. Under K.S.A. 65-2422a, the updated certificate will show the new name and be marked “amended,” but the sex marker will carry over from the original.5Kansas Office of Revisor of Statutes.

Legal Name Changes
Kansas imposes no transgender-specific restrictions on legal name changes. The standard process applies to everyone. You file a petition for change of name in the district court for your county of residence, along with a civil cover sheet, a proposed order, a photo ID, and the filing fee. You must notify anyone affected, such as a spouse, dependents, or creditors. Depending on the county, notice is given by publication in a local newspaper once a week for three consecutive weeks or by registered mail. After the notice period, the court holds a hearing. A judge will deny a name change only for reasons like fraud, avoiding debts, or an offensive requested name.
For a minor, a parent or guardian files the petition as a “next friend.” Both parents should ideally consent, and the minor must have been a Kansas resident for at least 60 days. The filing fee for a minor name change is typically around $195, though exact amounts vary by county.
Medical Care for Minors
Senate Bill 233, the Forbidding Abusive Child Transitions Act, prohibits specific medical treatments for anyone under 18 when the purpose is to align the minor’s appearance with a gender identity inconsistent with their biological sex.6Kansas Legislature. Senate Bill No. 233 The banned categories include:
- Sterilizing surgeries such as hysterectomy and orchiectomy, surgeries that construct tissue resembling genitalia, and mastectomy.
- Puberty-blocking drugs intended to delay or stop normal puberty, and supraphysiologic doses of testosterone for females or estrogen for males.
- Removal of any otherwise healthy body part or tissue for gender-transition purposes.
The restrictions are tied to purpose. Prescribing the same medications for an unrelated condition such as precocious puberty or a hormonal disorder is not prohibited, because the statutory definitions turn on why the treatment is given. Parental consent does not override the prohibition.
A physician who performs a prohibited treatment faces mandatory license revocation. Providers also face civil liability. Someone who received a banned treatment as a minor can sue the physician for actual damages, punitive damages, injunctive relief, and attorney fees. The statute of limitations runs three years from the date the person turns 18, so a patient treated at 14 could file suit as late as age 21.6Kansas Legislature. Senate Bill No. 233
School and College Athletics
The Fairness in Women’s Sports Act, codified in K.S.A. Chapter 60 Article 56, requires athletic teams at public K-12 schools and postsecondary institutions to be designated male, female, or coed based on biological sex. Teams designated for females, women, or girls cannot include students of the male sex.7Kansas State Legislature. Kansas Statutes 60-5601 – Fairness in Women’s Sports Act The rule also reaches private schools and colleges whose teams compete against public institutions.
Biological sex for athletic purposes is defined by sex chromosomes, naturally occurring hormones, gonads, and nonambiguous internal and external genitalia present at birth. A student who loses an athletic opportunity because of a violation can sue for injunctive relief and damages, as can a student who faces retaliation for reporting a violation. Civil actions must be filed within two years of the harm.8Kansas Legislature. House Bill No. 2238
NCAA Rules for College Athletes
Kansas college athletes also face NCAA-level restrictions. Effective February 2025, the NCAA limits competition in women’s sports to student-athletes assigned female at birth. A student assigned male at birth cannot compete on an NCAA women’s team, though they can still practice and receive other student-athlete benefits. A student assigned female at birth who begins testosterone therapy becomes ineligible for women’s competition, and the team is reclassified under mixed-team rules if that athlete competes.9NCAA.

Bathrooms, Shelters, and Other Sex-Segregated Spaces
K.S.A. 77-207(b) declares that sex-based distinctions in athletics, prisons, detention facilities, domestic violence shelters, rape crisis centers, locker rooms, restrooms, and other areas where biology, safety, or privacy are implicated meet intermediate constitutional scrutiny.1Kansas Office of Revisor of Statutes. Kansas Code 77-207 – Biological Sex; Application Thereof to Any State Law The statute does not create a criminal penalty for using a facility that doesn’t match your birth sex. What it does is give state-operated facilities, including public schools and universities, a legal basis to restrict access by biological sex and insulate those policies from equal protection challenges.
Private businesses are not directly bound by K.S.A. 77-207, which applies to state law and state-operated facilities. The broader framework still makes sex-based facility policies difficult to challenge under Kansas state law.
Workplace and Federal Protections
Kansas does not list gender identity as a protected class in its state anti-discrimination statutes. Federal law still provides a floor. The U.S. Supreme Court’s 2020 decision in Bostock v. Clayton County held that firing someone for being transgender is sex discrimination under Title VII of the Civil Rights Act, and that ruling binds Kansas employers with 15 or more employees regardless of what state definitions say.
Enforcement guidance has pulled back. In January 2026, the Equal Employment Opportunity Commission voted to rescind its 2024 guidance addressing harassment based on gender identity, including provisions on pronoun use and bathroom access. The rescission does not change Bostock itself, but it removes the detailed agency framework employers had been relying on. Private-sector employees in Kansos are left in a space where discrimination based on transgender status violates federal law while the agency’s interpretive guidance is thinner than it was.
Federal Identity Documents
Federal records have become more restrictive alongside state ones. A federal executive order in early 2025 defined sex as an immutable biological classification for federal purposes and directed agencies to remove references to gender identity. The Social Security Administration stopped processing sex designation changes in its records as of January 2025, even with a court order or medical documentation. The State Department stopped allowing sex or gender changes on U.S. passports. The Kansas driver’s license pathway remains open after the 2025 state court ruling, but federal documents and the Kansas birth certificate are closed under current rules.
Title IX in Schools
The 2024 Title IX rule that would have extended sex-discrimination protections to gender identity was vacated by a federal court in January 2025. The U.S. Department of Education has confirmed that the 2020 Title IX rule is the binding framework nationwide, and under that framework Title IX does not protect students from discrimination based on gender identity or sexual orientation. Kansas schools receiving federal funding follow both the state’s K.S.A. 77-207 definitions and this federal posture, which currently point in the same direction.
