Name change ยท Missouri
St. Louis Name Change Lawyer
A legal name change in Missouri is a court case with a petition, a hearing, and a publication requirement that trips up people who file on their own. We handle adult and minor name changes in St. Louis from start to finish, filing through publication, so the judgment holds and your records update without a second trip to court.
The first question most people ask
How do you legally change your name in Missouri?
You file a petition for change of name in the circuit court of the county where you live, under Section 527.270 of the Missouri Revised Statutes. The court sets a hearing, the judge reviews the petition and enters a judgment, and you then publish notice of the change in a newspaper and file proof with the court. Only after that last step is the change complete.
What the petition has to include
The court requires the petition to be verified (signed under oath) and to state:
- Your current legal name and the exact name you want
- Your reason for the change
- Your date and place of birth, and your parents’ names, including your mother’s maiden name
- Your spouse’s name if you are married, and the names, ages, and residence of any children
- Whether your name has been changed before, and if so, where and when
- Any pending lawsuits, judgments, or liens against you, with the court and case number
- A statement that the change is not sought to defraud anyone or avoid a debt or obligation
Most counties also require a copy of your birth certificate, a government ID, and proof of residency. We assemble the file so the clerk accepts it the first time. For a fuller walkthrough, see our step-by-step guide to Missouri name change law and how to legally change your name: cost, forms, and court steps.
The hearing and the publication rule
Name change hearings in St. Louis County, St. Louis City, and the surrounding counties are usually brief. The judge confirms the facts in the petition, asks why you want the change, and makes sure no one would be harmed by it. If the court grants the petition, it enters a judgment of change of name. What to expect is covered in what to expect at your name change hearing.
The step people miss comes after the judgment. Under Section 527.290, you must publish notice of the change in a newspaper of general circulation in your county within 20 days of the judgment, once a week for three consecutive weeks, and then file proof of publication with the court within 10 days after the last publication. Miss the window and the judgment can be set aside, which means starting over. We calendar the dates, place the notice, and file the proof.
A judge may deny a petition when the change appears intended to defraud creditors, evade a judgment or criminal record, or harm another person, or when the proposed name is obscene or misleading. The grounds are discussed in why a judge might deny a name change request.
Cost, timeline, and common situations
What a Missouri name change costs and how long it takes
Three costs make up the total: the court’s filing fee, the newspaper’s publication charge, and the attorney’s fee. The first two are set by the county and the paper; the third we quote up front.
How long it takes
From filing to a final, published judgment, an uncontested adult name change in the St. Louis area typically takes several weeks to a few months. The variable is the court’s hearing calendar; the publication period adds about a month after the judgment. Timelines by county are in how long a name change takes in Missouri.
Back to a prior name after divorce
If your divorce is still open, the request to restore a former name can be included in the dissolution judgment itself, with no separate case and no publication. If the divorce is already final and the judgment did not address it, a standard petition is the route. Part of our St. Louis divorce practice; the same applies in a legal separation.
After marriage
Taking a spouse’s surname after marriage usually does not require a court case; the marriage certificate is enough for Social Security and the DMV. A petition is needed for anything beyond that, such as a new surname for both spouses or a hyphenation the certificate does not show. See can you change your name without going to court in Missouri.
A child’s name change
A minor’s name can be changed by petition, but the court requires both parents to consent or, if one parent does not join, proof that the other parent was notified by certified or registered mail. That parent can appear at the hearing and object, and the court decides based on the child’s best interests. These cases often arise after a divorce, a remarriage, or a paternity judgment, and the facts matter, so talk to us before filing.
A name change to match your identity
Transgender and nonbinary clients use the same petition process. There is no medical documentation requirement in the statute, and the publication step can be handled with attention to privacy. We have guided many St. Louis clients through this and treat it as what it is: a routine legal process done respectfully. See protecting your privacy during a gender identity name change.
Changing your name a second time
Allowed, but the petition must disclose the earlier change and the court that granted it. Judges look more closely at repeat petitions, so the reason should be clear.
How we handle it
Filing through publication, in three steps
Most of our name change clients come to the office once, for the consultation, and attend the hearing. We do the rest.
1
Consultation and petition
We confirm the reason, check for anything a judge would question, gather your birth certificate and ID, and draft and file the verified petition in the correct county. You get the fee quote at this meeting.
2
Hearing and judgment
We prepare you for the questions the judge is likely to ask and attend the hearing with you. In most uncontested cases the judge signs the judgment that day or shortly after.
3
Publication and proof
We place the notice within the 20-day window, track the three weekly runs, and file the proof of publication within 10 days of the last one. You receive certified copies of the judgment to update your records.
After the judgment. Update Social Security first, then your Missouri driver’s license or ID, then your passport, bank accounts, employer, and insurance. Your birth certificate can be amended by sending a certified copy of the judgment to the vital records office of the state where you were born. What changes and what does not is covered in are there consequences to legally changing your name.
Common questions
Missouri name change questions we hear most
How much does it cost to change your name in Missouri?
The total is the court filing fee, which varies by county, plus the newspaper’s charge for three weeks of publication, plus the attorney’s fee. The court and publication costs are the same whether or not you hire a lawyer. We quote our fee at the consultation so you know the full number before you decide.
How long does a name change take in St. Louis?
Several weeks to a few months from filing to a published judgment. The hearing date depends on the court’s calendar, and the publication period runs about a month after the judgment. An uncontested petition with complete paperwork moves fastest.
Do I have to go to court for a name change?
Yes, for a petition under the name change statute. The judge holds a short hearing, and the petitioner attends. Some courts allow remote appearances; we tell you what your county does. The exceptions are a name taken at marriage, which needs no case, and a former name restored in a divorce judgment, which is handled inside that case.
Can a name change be denied?
Yes. A court may deny a petition that appears intended to defraud creditors, avoid a judgment or criminal history, or harm someone else, and may reject a name that is obscene, misleading, or would cause confusion. A third party can also object. A petition with a clear, honest reason is usually granted.
Can I go back to my maiden name without a separate name change case?
If your divorce is still pending, yes: ask for it in the divorce and the judgment restores the former name. If the divorce is final and the judgment is silent, you file a regular petition. Either way, the restored name is then used to update Social Security and your license.
One petition, one hearing, done right the first time.
