Montana law provides two paths for a name change after divorce: requesting restoration through your divorce decree under Mont. Code Ann. § 40-4-108, which costs nothing beyond the $200 dissolution filing fee, or filing a separate name change petition under Mont. Code Ann. § 27-31-101, which costs approximately $120 and requires 4 weeks of newspaper publication. The divorce decree method is faster, cheaper, and requires no publication.

How Does a Name Change After Divorce Work in Montana?
A name change after divorce in Montana works through one of two legal mechanisms: restoration via the divorce decree under Mont. Code Ann. § 40-4-108 at no additional cost, or a standalone petition under Mont. Code Ann. § 27-31-101 requiring a separate $120 filing fee and 4 weeks of publication. The divorce decree route is the preferred method because it eliminates extra court appearances, publication requirements, and fees.
When a party requests name restoration as part of a Montana dissolution proceeding, Mont. Code Ann. § 40-4-108 uses the word "shall," meaning the court is required to grant the restoration. Montana courts cannot deny a name restoration request made during divorce proceedings. The restored name can be a maiden name, birth name, or any former legal name the petitioner previously used.
Parties who did not request name restoration during their divorce must pursue the standalone petition process. This second path requires filing in the district court of the county where the petitioner resides, publishing a notice of hearing in a local newspaper for 4 consecutive weeks, and appearing at a court hearing. Montana courts have discretion to grant or deny standalone petitions, unlike the mandatory restoration under the divorce decree.
What Is the Easiest Way to Change Your Name During a Montana Divorce?
The easiest way to change your name during a Montana divorce is to include a name restoration request in your dissolution petition or marital settlement agreement, which adds no extra filing fee to the $200 dissolution cost and requires no publication under Mont. Code Ann. § 40-4-108. Montana district courts must grant this request when properly made.
To include the request, petitioners should specify the desired restored name in the dissolution petition. Montana Courts provide standardized forms at courts.mt.gov/Forms/end_marriage that include a name restoration section. The request can also be added through a stipulated agreement between the parties or raised at the final hearing.
The divorce decree itself then serves as the official legal document for updating records with every government agency. No separate court order is needed. Petitioners should request multiple certified copies of the decree from the district court clerk, as agencies including the Social Security Administration, Montana Motor Vehicle Division, and U.S. Department of State each require an original certified copy for processing.
What Are the Steps for a Standalone Name Change Petition in Montana?
A standalone name change petition in Montana requires filing a petition in district court, paying approximately $120, publishing a notice in a county newspaper for 4 consecutive weeks, and attending a court hearing, as prescribed by Mont. Code Ann. § 27-31-101 and Mont. Code Ann. § 27-31-201. The entire process typically takes 6 to 10 weeks from filing to final order.
The step-by-step process for a standalone name change petition in Montana is:
- Obtain the name change petition form from courts.mt.gov/Forms/namechange or the local district court clerk
- Complete the petition with your place of birth, current county of residence, present legal name, proposed name, and reason for the change
- File the petition with the district court clerk in the county where you reside and pay the filing fee (approximately $120, varies by county)
- Receive a hearing date from the court
- Publish notice of the hearing in a newspaper published in your county for 4 successive weeks under Mont. Code Ann. § 27-31-201
- File proof of publication with the court before the hearing
- Attend the court hearing and present your petition to the judge
- Receive the signed court order granting the name change
- Obtain certified copies of the court order from the clerk
- Update your name with government agencies and private institutions
Montana law provides a safety exception to the publication requirement. Under Mont. Code Ann. § 27-31-201, if a petitioner can show probable cause that publication would jeopardize their safety, the court may allow the petition to proceed under sealed records without publication. This exception does not apply to petitioners attempting to evade debts or hide criminal records.
How Much Does a Name Change After Divorce Cost in Montana?
A name change after divorce in Montana costs $0 extra when included in the divorce decree (covered by the $200 dissolution filing fee), or approximately $120 for the court filing fee plus $50 to $150 for newspaper publication when filed as a standalone petition, bringing the total standalone cost to $170 to $270. As of March 2026, verify current fees with your local district court clerk.
| Cost Component | Divorce Decree Route | Standalone Petition |
|---|---|---|
| Court Filing Fee | $0 (included in $200 dissolution fee) | ~$120 |
| Newspaper Publication | Not required | $50-$150 (4 weeks) |
| Certified Copies | $2-$5 per copy | $2-$5 per copy |
| Attorney Fees (optional) | Included in divorce representation | $200-$500 |
| Total Estimated Cost | $0-$10 | $170-$275 |
Montana offers fee waivers for petitioners who cannot afford filing fees. Individuals may file an Affidavit of Inability to Pay (in forma pauperis application) with the district court. The court reviews the applicant's financial situation and may waive all or part of the filing fee. Fee waiver forms are available at courts.mt.gov/selfhelp or from the district court clerk.
What Documents Do You Need to Change Your Name After Divorce in Montana?
Changing your name after divorce in Montana requires a certified copy of the divorce decree containing the name restoration order (for the decree route) or a signed court order granting the name change (for the standalone route), plus a valid government-issued photo ID and your Social Security card. Montana agencies require original certified documents, not photocopies.
The complete document checklist for a Montana divorce name change includes:
- Certified copy of the divorce decree with name restoration language (request 3 to 5 copies from the district court clerk at $2 to $5 each)
- Current valid Montana driver license or state ID
- Social Security card (current name)
- Birth certificate (original or certified copy)
- U.S. passport (if updating passport)
- Vehicle registration documents (if updating title)
- Voter registration card
- Current lease or mortgage documents
For standalone petitions filed under Mont. Code Ann. § 27-31-101, additional documents include the completed petition form, proof of Montana residency (utility bill, lease, or bank statement), and proof of publication from the newspaper after the 4-week notice period.
What Is the Order for Updating Your Name with Government Agencies?
The correct order for updating your name after a divorce in Montana starts with the Social Security Administration, followed by the Montana Motor Vehicle Division within 48 hours of SSA processing, then the U.S. Department of State for passport updates. Montana MVD checks names against SSA records, so updating Social Security first prevents processing delays and rejected applications.
The recommended update sequence is:
-
Social Security Administration (SSA): Submit Form SS-5 (Application for a Social Security Card) in person at a local SSA office with your certified divorce decree and current government-issued photo ID. Processing takes approximately 14 business days. You will receive a new Social Security card reflecting your restored name at no charge.
-
Montana Motor Vehicle Division (MVD): Wait at least 48 hours after SSA processes your name change, then visit a Montana MVD office with your certified divorce decree and current driver license. The MVD verifies your name against SSA records electronically. A replacement license fee applies (approximately $12.08 for a standard license as of 2026).
-
U.S. Passport: Submit Form DS-5504 (if your current passport was issued less than 1 year ago) or Form DS-82 (standard renewal) by mail with your certified divorce decree. Routine processing takes 6 to 8 weeks. Expedited processing is available for an additional $60, reducing the timeline to 2 to 3 weeks.
-
Internal Revenue Service (IRS): The IRS does not require a separate notification. Your name on future tax returns must match SSA records, so updating Social Security automatically updates your IRS records. File any tax returns after the SSA change is processed to avoid mismatches.
-
Additional Updates: Contact your bank, employer payroll department, health insurance provider, mortgage company, utility providers, credit card companies, and voter registration office. Each institution has its own documentation requirements, but most accept a certified copy of the divorce decree.
Can You Change Your Name to Something Other Than Your Maiden Name?
Montana law allows name restoration through a divorce decree only to a maiden name, birth name, or former legal name under Mont. Code Ann. § 40-4-108. Changing to an entirely new name that you have never legally held requires a standalone name change petition under Mont. Code Ann. § 27-31-101, which involves the full petition, publication, and hearing process.
The distinction is important for individuals who have been married more than once. A person married three times, for example, can request restoration to any of their previous legal names through the divorce decree, including a name from a prior marriage. Montana courts interpret "former name" broadly to include any name the petitioner has legally used.
For a completely new name, the standalone petition process applies regardless of whether a divorce is pending. The petitioner must state the reason for the desired change in the petition, and Montana district courts have discretion to approve or deny the request. Courts generally approve name change petitions unless there is evidence of fraudulent intent, an attempt to evade debts, or an effort to conceal a criminal record.
What Is Montana's Residency Requirement for Filing a Divorce Name Change?
Montana requires at least one spouse to have been domiciled in the state for a minimum of 90 days immediately before filing a dissolution petition under Mont. Code Ann. § 40-4-104. For a standalone name change petition, the petitioner must file in the district court of the county where they currently reside under Mont. Code Ann. § 27-31-101, though no minimum residency duration is specified for standalone petitions.
Montana's 90-day residency requirement for divorce is among the shortest in the United States. For comparison, California requires 6 months (180 days), New York requires 1 year for certain grounds, and Florida requires 6 months (180 days). Military personnel stationed in Montana satisfy the residency requirement through their duty station assignment, even if their home of record is another state.
The petition must be filed in the district court of the county where either spouse has resided for the preceding 90 days. Montana has 56 counties, each served by a district court. If neither spouse currently resides in Montana but one meets the 90-day requirement through recent relocation, the filing should occur in the county of most recent Montana residence.
How Long Does a Name Change After Divorce Take in Montana?
A name change after divorce in Montana through the divorce decree takes effect immediately upon entry of the final decree, which can occur as soon as 20 days after service of the dissolution petition under Montana's mandatory waiting period. A standalone name change petition takes 6 to 10 weeks from filing to final order due to the 4-week publication requirement and court scheduling.
| Timeline Component | Divorce Decree Route | Standalone Petition |
|---|---|---|
| Filing to Hearing | 20-day minimum waiting period | 5-8 weeks (includes publication) |
| Publication Period | Not required | 4 consecutive weeks |
| Court Hearing | Included in dissolution hearing | Separate hearing required |
| Order Effective Date | Date of final decree | Date of signed order |
| SSA Processing | 14 business days | 14 business days |
| MVD Processing | Same day (after SSA) | Same day (after SSA) |
| Passport Processing | 6-8 weeks (routine) | 6-8 weeks (routine) |
| Total End-to-End | 4-8 weeks | 10-16 weeks |
Montana's 20-day waiting period begins when the respondent is served with the dissolution papers. For uncontested divorces where both parties file affidavits, no hearing is required, and the court can enter the decree after the 20-day period expires. Contested divorces involving disputes over property, parenting, or support can extend the timeline to 6 months or longer, though the name restoration request itself does not add time to the process.
Does Montana Require Publication for a Divorce-Related Name Change?
Montana does not require newspaper publication when a name change is requested through a divorce decree under Mont. Code Ann. § 40-4-108. Publication is only required for standalone name change petitions filed under Mont. Code Ann. § 27-31-201, where notice must appear in a county newspaper for 4 consecutive weeks before the hearing date.
The publication requirement for standalone petitions serves as public notice, allowing creditors or other interested parties to object to the name change. If no newspaper is published in the county, the petitioner must post notice in at least 3 public places within the county for 4 successive weeks. Proof of publication or posting must be filed with the court before the hearing.
Montana provides a sealed-record exception for individuals whose safety would be jeopardized by publication. Under Mont. Code Ann. § 27-31-201, a petitioner may request that the court waive publication and seal the name change records if they demonstrate probable cause of a safety risk, such as domestic violence. The court will not grant this exception to petitioners attempting to evade lawful debts or conceal criminal history.
What Recent Montana Law Changes Affect Divorce Name Changes?
Montana Senate Bill 372, enacted during the 2025 legislative session, expanded simplified summary dissolution eligibility to include couples with children who have an agreed-upon parenting plan. Previously, summary dissolution was limited to childless couples. No 2024-2026 legislative changes directly modified Montana's name change statutes under Title 27, Chapter 31 or the divorce decree name restoration provision under Mont. Code Ann. § 40-4-108.
SB 372's expansion of summary dissolution means more divorcing couples in Montana can use the streamlined process, which includes name restoration. Summary dissolutions require less paperwork, lower attorney involvement, and faster processing. Couples with children who agree on a parenting plan can now access this simplified pathway, reducing costs and court time for both the divorce and any associated name restoration request.
Montana's name restoration statute (Mont. Code Ann. § 40-4-108) has remained substantively unchanged for over a decade. The mandatory "shall" language ensuring courts must grant name restoration requests was established in the original statute and continues to protect petitioners' rights to reclaim their former names through the dissolution process.
Frequently Asked Questions
Can I change my name back to my maiden name after my Montana divorce is already final?
Yes, but if your final Montana divorce decree does not include a name restoration order, you must file a standalone name change petition under Mont. Code Ann. § 27-31-101. This requires a separate filing fee of approximately $120, 4 weeks of newspaper publication costing $50 to $150, and a court hearing. The total process takes 6 to 10 weeks.
Is a name change after divorce automatic in Montana?
No, a name change after divorce in Montana is not automatic. You must specifically request name restoration in your dissolution petition or marital settlement agreement under Mont. Code Ann. § 40-4-108. Once requested, the court is legally required to grant it, but the request itself must be made explicitly. Omitting the request means filing a separate petition later.
How many certified copies of my divorce decree should I order for a name change?
Order 3 to 5 certified copies of your Montana divorce decree from the district court clerk at $2 to $5 per copy. The Social Security Administration, Montana Motor Vehicle Division, and U.S. Department of State each require an original certified copy. Banks and employers may also require certified copies rather than photocopies.
Can my ex-spouse prevent me from changing my name back?
No, a spouse cannot prevent name restoration in a Montana divorce. Under Mont. Code Ann. § 40-4-108, the court "shall" order name restoration upon request, and no spousal consent is needed. Montana law treats name restoration as an individual right, not a negotiable term of the divorce settlement. The opposing party has no legal standing to object.
Do I need a lawyer to change my name after divorce in Montana?
No, Montana does not require an attorney for either divorce-related name restoration or a standalone name change petition. Montana Courts provide free self-help forms at courts.mt.gov/Forms/namechange and courts.mt.gov/Forms/end_marriage. Montana Legal Services Association (montanalawhelp.org) offers free legal guidance for self-represented litigants.
How do I change my children's last name after divorce in Montana?
Changing a child's last name in Montana requires filing a standalone name change petition under Mont. Code Ann. § 27-31-101 on the child's behalf. Both parents must consent in writing, and if both consent, no publication is required. If one parent objects, the court holds a hearing and decides based on the child's best interests. A child's name cannot be changed through a parent's divorce decree name restoration.
Will changing my name affect my divorce settlement or property rights?
No, a name change after divorce in Montana has no effect on property division, alimony, child support, or parenting plan provisions. Under Mont. Code Ann. § 40-4-108, name restoration is a separate provision from the financial and custodial terms of the decree. All rights and obligations established in the divorce decree remain fully enforceable regardless of a name change.
What if I moved out of Montana after my divorce and need to change my name?
If your Montana divorce decree includes a name restoration order, you can use that decree to update your name with the Social Security Administration and other federal agencies from any state. For state-level updates like a driver license, you must follow the name change procedures of your current state of residence. Montana's divorce decree is recognized as a valid legal name change document in all 50 states.
Can I change my name to my maiden name if I got married in another state but live in Montana?
Yes, Montana's 90-day residency requirement under Mont. Code Ann. § 40-4-104 applies to where you currently live, not where you were married. If you have been domiciled in Montana for at least 90 days, you can file for divorce in Montana district court and request name restoration regardless of where the marriage took place or where your spouse currently resides.
How do I update my Montana voter registration after a divorce name change?
Update your Montana voter registration after a name change by submitting a new voter registration form with your restored name to your county election administrator. Montana allows same-day voter registration, so you can update at any time, including on Election Day. Bring your certified divorce decree and updated Montana driver license to the county election office or register online at sosmt.gov if your MVD records are already updated.
