Montana Name Change: Petition, Hearing, and Updating Records

To legally change your name in Montana, file a petition in the district court of the county where you live, publish notice of the hearing in a local newspaper for four consecutive weeks, attend a short court hearing, and then use the signed order to update your records with Social Security and every other agency. Filing costs $120, and the whole process usually runs six to eight weeks at a minimum because of the publication requirement. The rules sit in Title 27, Chapter 31 of the Montana Code.

If Your Name Change Comes From a Marriage or Divorce

Skip the petition. A marriage certificate, a declaration of marriage filed with a district court clerk, or a divorce decree that specifies a name change is itself the legal document authorizing the change.¹ Take it directly to Social Security, the MVD, and anywhere else your name appears. You only need the court petition described below if your divorce decree did not restore a former name, or if your reason is unrelated to marriage or divorce.

Who Can File

Any Montana resident can petition in the district court of the county where they currently live. There is no minimum residency period.² Adults sign for themselves. For anyone under 18, a living parent signs; if both parents are deceased, a guardian or close relative signs instead.

The court will not grant a name change intended to evade debts or hide a criminal record, and the court forms require you to declare that neither motivation applies.³ Petitioners who are incarcerated or under Department of Corrections supervision face extra steps, described further down.

Filing the Petition

Download the packet from the Montana Judicial Branch website. It contains the Petition for Name Change, an Order Setting Hearing, a Notice of Hearing on Name Change, and an Order for Name Change.⁴ The petition asks for your place of birth, current residence, current legal name, the name you want, and your reason for the change. If neither parent is living, list your known close relatives and their addresses.²

Take the originals and a set of copies to the Clerk of District Court at your county courthouse. The filing fee is $120.⁵ If you can’t afford it, ask the clerk for an Affidavit of Inability to Pay; the court can waive costs for people who qualify.³ Have the clerk stamp your copies “Filed” and leave a self-addressed stamped envelope so the judge’s order setting the hearing date can be mailed to you.

Publishing Notice

Once you have a hearing date, you must publish notice of it in a newspaper in your county once a week for four successive weeks before the hearing.⁶ If no newspaper is published in your county, you can post the notice in at least three public places for the same four-week stretch.³

Publication costs vary with the newspaper’s classified rates, running from around $150 to several hundred dollars. Keep the receipt or proof of publication; you may need to show it at the hearing. This four-week notice period is what drives the timeline.

There are two exceptions. Publication is waived for a minor’s name change when both parents and all legal guardians consent in writing. Publication is also set aside when the court allows a sealed-record petition because your safety is at risk.⁶

The Hearing

Show up at the courthouse at least 15 minutes early. Bring your filed-stamped copies, your proof of publication, and both the original and a copy of the Order for Name Change with as many blanks filled in as you can.³ The judge will ask you to explain why you want the change. Most uncontested hearings last only a few minutes.

If no one has objected and the judge is satisfied with your reason, the court signs the order. Take it to the Clerk of District Court right after the hearing and get certified copies. The certified order is the document you’ll use everywhere else.

Sealed-Record Petitions for Safety

If publishing your name change would put you in danger, ask for sealed-record treatment in the petition itself. You must show probable cause that your safety is at risk, and the judge still has to be satisfied that you’re not trying to duck debts or hide a criminal record.⁶ When the court grants it, all papers become permanent court records but are withheld from public inspection. No one other than the petitioner can access them without a court order showing good cause. This option is used mainly by domestic violence survivors and others whose former name could be used to locate them.

Name Changes for a Child

A parent or guardian files on the child’s behalf. At least one living parent must sign; a guardian or close relative signs if both parents are deceased.² Judges weigh the child’s best interests and look for a meaningful reason, such as adoption or a stepparent relationship.

When both parents and all legal guardians consent in writing, publication is waived entirely, which can cut weeks off the timeline.⁶ If one parent objects or can’t be located, the court proceeds more carefully. The non-consenting parent should be notified and given a chance to be heard, and in contested cases the judge may appoint a guardian ad litem.

Incarcerated Petitioners

People in state prison or under Department of Corrections supervision can still petition, but the petition must be served on the Department of Corrections, and the court must give the department a reasonable chance to appear and respond. The department will also try to contact registered victims.⁶ Even after a name change is granted, the Department of Corrections and the Department of Justice retain the authority to maintain and share records under both old and new names so that registration and notification obligations remain enforceable.

Objections

Anyone can file an objection before the hearing by showing the court “good reasons” against the change.⁷ The statute leaves “good reasons” to the judge’s discretion, but objections grounded in evidence of fraud, harm to a child, or interference with legal obligations carry the most weight. Objections are uncommon for adult petitions and arise most often when a non-custodial parent opposes a change for a minor. A vague or unsupported objection rarely derails an otherwise legitimate petition.

Updating Your Records After the Order

The court order is the beginning, not the end. Doing these steps out of order is what causes rejected tax returns, frozen accounts, and airport headaches. Work in this sequence.

Social Security First

Update Social Security before anything else, because most other agencies verify names against SSA data. Bring your court order and proof of identity to request a replacement Social Security card.⁸ Some applicants can start online; others need an in-person appointment. Replacement cards typically arrive in 5 to 10 business days.⁹

Montana Driver’s License

Wait at least 24 hours after Social Security is updated before visiting the Motor Vehicle Division. The MVD verifies your name against SSA records, and a mismatch will get your application denied.¹ Schedule an in-person appointment at a Driver Exam Station and bring your current license along with a certified copy of the court order.

U.S. Passport

Which form and fee apply depends on how recently your passport was issued. If it was issued less than a year ago and your name changed within that year, use Form DS-5504 at no charge (expedited processing costs $60 extra). Otherwise use Form DS-82 by mail or DS-11 in person, with standard passport fees. In every case, submit the original or a certified copy of your court order and a new passport photo.¹⁰

IRS and Taxes

The IRS has no separate name-change process; it pulls your name from Social Security. Once SSA is updated, file your next return using the new name exactly as it appears on your Social Security card. A mismatch can delay your refund.¹¹ If you receive W-2s or 1099s in your former name for part of the year, ask each payer for a corrected form and file a single return covering all your income.

Credit Bureaus, Banks, and Everything Else

Notify Equifax, Experian, and TransUnion individually; updating one does not update the others. Each has an online process that accepts your court order or updated driver’s license, and processing can take up to 30 days. Contact your banks, credit card issuers, mortgage servicer, insurance carriers, and employer directly to update account records.
