Legal Name Change in Missouri: Court-Ordered Process
Petition the Missouri Circuit Court for a name change. We’ll fill out the petition + every follow-up form for free.
A court-ordered name change in Missouri uses a verified Petition for Change of Name filed at the Circuit Court in your county of residence under state statute Section 527.270. Filing fees run $50-$150 (varies by county); newspaper publication is required for 3 consecutive weeks at $50-$150; certified copies $5-$25 each. Total typical: $100-$350. The process takes 6-12 weeks from filing to your signed court order. We fill out the petition, fee waiver request, and every follow-up form — and walk you through Social Security, passport, and Missouri Department of Revenue updates after your hearing.
Missouri Name Change Forms
Missouri does not use standardized statewide form numbers. Most counties provide their own petition templates through the circuit court clerk's office.
Verified petition with your current name, requested name, reason for change, date of birth, address, and statement that you are not seeking to avoid debts or legal obligations.
Public notice published in a county newspaper for 3 consecutive weeks, allowing anyone with objections to come forward.
Final court order signed by the circuit court judge after your hearing. Your legal proof of name change.
If you can’t afford the $50-$150 filing fee. Approved based on financial hardship. Ask the circuit court clerk for the local form.
Step-by-Step Missouri Name Change Process
Same 4-step path in every county, with local variation in fees and forms.
Step 1: File Your Petition with the Circuit Court
File your verified petition at the Circuit Court in your county of residence. Missouri name change cost varies by county, with filing fees typically ranging from $50 to $150. Bring your completed petition, the filing fee or fee waiver request, and a copy of your current ID.
Your petition must include your current full legal name, the exact new name you want, and a clear explanation of why you’re requesting the change. Missouri requires the petition to be “verified by affidavit,” meaning you must sign it under oath. Common explanations include personal preference, professional considerations, cultural significance, or gender identity affirmation.
The petition should also include your date of birth, current address, and a statement that you’re not seeking the name change to avoid debts or legal obligations. Most Missouri counties have standard petition forms available through their circuit court clerk’s office or website. When filing, ask the clerk about your county’s specific procedures — some courts schedule hearings automatically, while others require you to request a hearing date separately.
Step 2: Publish Notice (3 Weeks)
Most Missouri counties require publication of your name change petition in a local newspaper once a week for 3 consecutive weeks. Cost: $50-$150 depending on the newspaper.
This publication requirement allows anyone with objections to your name change to come forward. Publication costs vary by newspaper and county requirements.
Some counties may waive publication for safety reasons, such as in cases involving domestic violence — ask your clerk about possible exceptions. You’ll typically need to provide documentation of the threat, such as a restraining order or police report.
Step 3: Attend Your Court Hearing
After the publication period, you’ll attend a hearing before a Missouri circuit court judge. Bring a valid photo ID and any supporting documents that explain your reason for the name change. The hearing is typically brief.
The judge will typically ask you:
- To state your current name and the new name you’re requesting
- Why you want to change your name
- Whether you’re trying to avoid debts, criminal charges, or other legal obligations
- Whether you understand that changing your name requires updating all your legal documents
Dress professionally and speak clearly. The judge wants to ensure your request is legitimate and won’t harm others. If no one has filed objections and your request meets legal requirements, the judge will grant your petition and issue a court order legally changing your name.
If you’re changing a minor’s name, both parents typically need to consent unless one parent’s rights have been terminated or they cannot be located.
Step 4: Get Your Certified Court Order
Once approved, request several certified copies of your name change order from the court clerk — typically 3-5 copies at $5-$25 each, depending on your county.

Special Situations in Missouri
Missouri has specific considerations for minors, gender identity, and domestic violence survivors.

Minor Children Name Changes
Changing a minor child’s name in Missouri requires both parents’ consent unless one parent’s rights have been terminated or they cannot be located after reasonable efforts.
- Both parents must consent — or the petitioning parent must prove diligent effort to locate and notify the other parent
- Best-interest standard applies — the court evaluates the child’s best interests when making this decision
- Additional documentation may be required — such as birth certificates and custody agreements
- Termination of parental rights — consent isn’t needed from a parent whose rights have been terminated
See our minor name change guide for the full process.
Gender Identity Name Changes
Missouri courts handle gender identity-related name changes through the same petition process. You don’t need to disclose medical information or provide documentation of gender transition.
- No medical documentation required — simply state that the name change reflects your gender identity
- Same legal process — the standard petition steps apply statewide
- County variation — some counties may be more familiar with these requests than others
See our gender identity name change guide.
Domestic Violence Exemptions
If publication of your name change could endanger your safety, some Missouri courts may waive the publication requirement. Discuss this option with the court clerk when filing your petition.
- Publication waiver — skip the 3-week newspaper publication entirely
- Documentation required — restraining order, police report, or similar evidence of the threat
- Discuss with clerk early — raise this option when filing the petition

Frequently Asked Questions
How long does a legal name change take in Missouri?
A Missouri legal name change typically takes 6-12 weeks from filing your petition to receiving your court order. This includes time for publication (if required), court scheduling, and processing. Counties with busy court systems may take longer.
Can I change my name in Missouri without a lawyer?
Yes, you can petition for a name change in Missouri without hiring a lawyer. The process is designed for self-representation, and most counties provide the necessary forms. However, complex situations involving minor children or contested changes may benefit from legal advice.
What if someone objects to my Missouri name change?
If someone files an objection during the publication period, the court will hold a hearing where both sides can present their arguments. Objections are rare and typically only succeed if the name change would cause confusion, facilitate fraud, or harm others' interests.
Can I change my child's last name to match my new spouse's name?
Yes, but you'll need consent from both biological parents or a court order if the non-custodial parent objects. Missouri courts consider the child's best interests, existing relationships, and reasons for the change when making this decision.
Do I need to live in Missouri for a certain period before filing?
Missouri doesn't specify a minimum residency period for name changes, but you must be a resident of the county where you file. You'll need to provide your current Missouri address and may be asked to verify your residency at the hearing.
Will my Missouri name change be recognized in other states?
Yes, a Missouri court order for name change is valid in all 50 states. Other states must recognize your legal name change under the Full Faith and Credit Clause of the U.S. Constitution. Keep certified copies of your court order when traveling or moving.
