Missouri-Specific Details
Missouri name change petitions are filed in the Circuit Court of your county of residence. Major filing courts include the St. Louis County Circuit Court in Clayton, the Jackson County Circuit Court in Kansas City, and the City of St. Louis Circuit Court (which is independent of St. Louis County — a structural quirk that confuses many out-of-state filers). Filing fees vary by county and typically run $150–$450. Missouri requires publication of your petition once a week for three successive weeks in a county-approved newspaper before the court will set a hearing date.
The St. Louis Daily Record and the Daily Record in Kansas City are the legal-notice publications most petitioners use, with the St. Louis Post-Dispatch and Kansas City Star handling general circulation. Publication runs $40–$200 depending on circulation. Missouri has notably progressive identity-document policies — the Department of Revenue's driver license bureau allows self-attestation for gender marker changes and offers a nonbinary "X" option on licenses, no court order or medical letter required for the gender update itself.
For your driver's license update, the Missouri DOR charges $12 (one of the lower fees nationally) and does not require an appointment at most license offices — walk-ins are accepted. The St. Louis County license offices in Clayton and Florissant tend to see the heaviest volume; offices in Springfield and Columbia process updates faster. Bring your certified court order, current license, and updated Social Security card. Your new license arrives by mail in 1–4 weeks. Order three to four certified copies of the court order to handle SSA, passport, banking, and employer updates simultaneously. Estimate your total at our cost calculator.

Marriage Name Change in Missouri
In Missouri, your certified marriage certificate is your legal name change document — no court order, no publication, no extra fees beyond county-issued certified copies ($10–$15 each).
If you're changing your name after marriage in Missouri, you don't need to go to court. Your certified marriage certificate serves as your legal proof of name change for all agencies and organizations.
Step 1: Get certified copies of your marriage certificate. Request at least 3-5 certified copies from the county clerk's office where your marriage license was issued. Each copy typically costs $10-15.
Step 2: Update Social Security first. Visit your local Social Security office with your driver's license, certified marriage certificate, and Social Security card. You'll fill out Form SS-5 and receive your updated card in 2-4 weeks at no charge.
Step 3: Update your Missouri driver's license. Wait 24-48 hours after your SSA visit, then go to a Missouri Department of Revenue office. Bring your current license, marriage certificate, new Social Security card, and $12 for the replacement fee.
Step 4: Update other documents. With your updated driver's license and Social Security card, you can now update your passport, bank accounts, employer records, and other important documents.
The entire process typically takes 3-4 weeks from start to finish. Missouri recognizes name changes for any spouse in a marriage, regardless of gender, making this one of the most straightforward name change processes available.

Divorce Name Change in Missouri
Missouri offers two paths: name restoration written into your divorce decree (free, easy), or a separate Circuit Court petition after the divorce is final.
Missouri allows you to restore your prior name as part of your divorce proceedings or petition separately afterward. Most people find it easier to include name restoration in their original divorce petition.
During divorce proceedings: Ask your attorney to include name restoration language in your divorce petition and final decree. The judge will typically grant this request without additional hearings or fees. Your certified divorce decree will then serve as proof of your name change.
After divorce is final: If you didn't request name restoration during your divorce, you'll need to file a separate petition for name change with the circuit court. This follows the same process as an adult court-ordered name change, including publication requirements and court fees.
The restored name must be a name you were legally entitled to use before marriage, typically your birth name or a previous married name. You cannot choose an entirely new name through divorce name restoration — that requires a separate court-ordered name change petition.
Once you have your certified divorce decree with name restoration, follow the same document update process as marriage: Social Security first, then DMV, then other agencies and organizations.

Court-Ordered Name Change in Missouri (Adult)
For any name change that's not through marriage or divorce. File a Petition for Change of Name with the Circuit Court in your county. Filing fees run $100–$300; publication runs 3–4 weeks at $40–$200.
Adult court-ordered name changes in Missouri require filing a petition with your local circuit court. This process applies when you want to change your name for reasons other than marriage or divorce, such as personal preference, family reasons, or gender identity.
Step 1: File your petition. Submit a "Petition for Change of Name" to the circuit court clerk in your county of residence. The petition must include your current name, requested new name, reason for the change, and an affidavit stating you're not changing your name to avoid debts or legal obligations. Filing fees vary by county but typically range from $100-300.
Step 2: Publish legal notice. Missouri law requires publishing your name change petition in a local newspaper for four consecutive weeks. The newspaper will charge additional fees, typically $100-200. This gives the public notice of your intended name change and allows for objections.
Step 3: Attend your court hearing. After the publication period, you'll have a brief hearing before a judge. Bring photo identification and be prepared to explain your reason for the name change. The judge will grant your petition unless there's evidence of fraud or other legal issues.
Step 4: Get certified copies of your court order. Request multiple certified copies of your name change decree from the court clerk. You'll need these for updating all your documents and identification.
The entire court process typically takes 30-60 days from filing to final order. Missouri courts generally approve name change requests unless the petitioner has a criminal history involving fraud, is trying to avoid debts, or the requested name would cause confusion or harm to others.
Missouri does not require you to hire an attorney for a standard adult name change, though some people choose legal representation for complex situations.

Minor Name Change in Missouri
Missouri requires Circuit Court approval for any minor name change. Both parents must typically consent and appear; sole-custody parents can petition alone with custody documentation.
Changing a minor's name in Missouri requires court approval and careful attention to parental consent requirements. The process protects the child's interests while respecting parental rights.
When both parents agree: Both parents must sign the petition for name change and appear at the court hearing. If one parent has sole custody, that parent can petition alone with proper documentation of their custody status.
When parents disagree: The petitioning parent must provide legal notice to the other parent, who can object to the name change. The court will then decide based on the child's best interests, considering factors like the child's wishes (if age-appropriate), relationship with both parents, and reasons for the name change.
Required documents include:
- Petition for Change of Name (Minor)
- Child's certified birth certificate
- Custody documentation (if applicable)
- Consent forms from both parents (when required)
- Filing fee (varies by county)
The court may appoint a guardian ad litem to represent the child's interests in contested cases. Publication in a local newspaper is typically required unless waived by the court.
After the court approves the name change, you'll need to update the child's Social Security record first, then their birth certificate through the Missouri Department of Health and Senior Services. School records, medical records, and other documents should also be updated with certified copies of the court order.

Gender Identity Name Change in Missouri
Missouri allows self-attestation for driver's license gender markers (M, F, or X) — no court order or medical letter needed. Birth certificate updates require a separate court order through DHSS Vital Records.
Missouri allows name changes as part of gender identity affirmation through the standard court petition process. The state has made significant progress in recognizing transgender rights, though some administrative challenges remain.
Name change process: Follow the standard adult court-ordered name change procedure described above. Missouri courts generally approve name changes requested as part of gender identity affirmation, treating them like any other personal name change petition.
Driver's license gender marker: Missouri now allows self-attestation for gender marker changes on driver's licenses and state IDs. You can update your gender marker to M, F, or X (non-binary) without requiring court orders or medical documentation. Visit your local Department of Revenue office with appropriate identification and request the change.
Birth certificate changes: Missouri allows birth certificate gender marker changes for people born in the state. You'll need a court order specifically addressing gender marker change, which may require additional documentation. Contact the Missouri Department of Health and Senior Services Bureau of Vital Records for current requirements.
Tips for success:
- Consider updating your driver's license gender marker at the same time as your name change
- Gather supporting documentation that affirms your gender identity
- Some counties are more experienced with these petitions than others
- Consider consulting with an attorney familiar with transgender legal issues
Missouri's approach to transgender name and gender marker changes continues evolving. While the legal framework supports these changes, individual experiences may vary by county and court.
