Montana: Adult Legal Name Change Requirements
The short answer
A Montana adult petitions the district court in the county of residence, publishes the hearing notice once weekly for four successive weeks, and attends a hearing. The standard civil commencement fee is $120, with a fee-waiver affidavit available. A sealed-record safety route replaces public notice when the statutory probable-cause findings are met, while people in Department of Corrections custody or supervision must serve the department and use a separate track.

| Governing law and court | Mont. Code Ann. §§ 27-31-101, 27-31-201 to -204; file in the district court of the county where the adult resides |
|---|---|
| Who may petition and residency | Adult resident petitions in county of residence; no minimum residence period stated (§ 27-31-101) |
| Petition contents and oath | Signed petition states place of birth and residence, present and proposed names, and reason; current form adds date of birth, nearest relatives if both parents are dead, birth-record choice, and no-debt/no-hidden-record/no-improper-purpose declaration. No notarization or verification oath on current ordinary form |
| Criminal background check | No fingerprints, state/FBI report, or routine court background check required by chapter or current ordinary packet. Form requires a declaration that the change is not to hide a criminal record; custody/supervision status triggers Department of Corrections service |
| Publication or notice | Publish hearing notice in a county newspaper for 4 successive weeks, currently once weekly; if no county newspaper, post in at least 3 public places for 4 successive weeks. Bring proof before hearing (§§ 27-31-201(1), 27-31-203; court packet) |
| Safety, confidentiality, and special tracks | Court may proceed under sealed record on probable cause that safety is at risk and satisfaction that petitioner is not avoiding debt or hiding a criminal record. Request must be in petition; nonpetitioner access generally requires good cause and court order. No separate gender-identity track (§ 27-31-201(3)) |
| Hearing and grant standard | Hearing follows proof of publication/posting; court may examine people under oath. Anyone may object before hearing with good reasons; court grants or dismisses as right and proper (§§ 27-31-202 to -204) |
| Grounds for denial or restriction | Court retains right-and-proper discretion; ordinary form requires no debt avoidance, hidden criminal record, or improper purpose. Corrections-custody/supervision petitioner must serve department; department may respond and must try to contact a victim. Grant preserves corrections/justice record dissemination (§ 27-31-201(4)-(5)) |
| Fee and post-order effect | $120 statewide civil-commencement filing fee; affidavit of inability to pay available. Current order makes new name valid for all legal documents and can direct Montana birth-record amendment or a new sealed birth record; certified copies used for other updates |

Requirements one by one
File a signed petition in the resident county's district court
Under Mont. Code Ann. § 27-31-101, the adult files in the district court of
the county where the adult resides. Montana states no minimum residence period.
The petition must give the adult's place of birth and residence, present name,
proposed name, and reason. If both parents have died, it also identifies the
nearest known relatives and their residences.
The current Judicial Branch form adds date of birth, birth-record options, and
a declaration that the request is not meant to avoid debt, hide a criminal
record, or serve another improper purpose. The adult signs the ordinary form;
it contains no notarization block or verification oath. Neither the chapter nor
the ordinary packet requires fingerprints or a routine state or FBI report.
Publish for four weeks and attend the hearing
Under § 27-31-201(1), the hearing notice must be published for four
successive weeks in a newspaper published in the county. The current packet
implements that as one publication each week. If the county has no newspaper,
the adult posts the notice in at least three public places for the same four
weeks. Proof of publication or posting must be produced before the hearing.
Anyone may file objections before the hearing by showing good reasons against
the change under § 27-31-202. Under § 27-31-203, the application must
then be heard, and the court may examine the petitioner, objectors, or others
under oath. § 27-31-204 lets the court grant or dismiss the request as
right and proper.
A safety-risk petition may proceed under sealed record
Under § 27-31-201(3), the adult must request sealed-record treatment in the
petition and show probable cause that public disclosure puts the adult's safety
at risk. The judge must also be satisfied that the request is not intended to
avoid debt or hide a criminal record.
If granted, all papers remain a permanent court record but are withheld from
inspection. Subject to the corrections provisions, a nonpetitioner may obtain
access only for good cause and by court order. Montana has no separate statutory
gender-identity name-change track.
Corrections custody or supervision adds service and victim contact
The ordinary self-help packet is not for a person in Department of Corrections
custody or supervision. Current § 27-31-201(4)-(5) does not impose a flat
ineligibility rule. Instead, the person serves the department, the court gives
the department a reasonable opportunity to respond, and the department makes
reasonable efforts to contact a victim for relevant information. If the change
is granted, the order must preserve Department of Corrections and Department of
Justice authority to maintain and disseminate records for registration,
biological-sample, victim-notification, and other legal duties.
The standard civil filing fee is $120
The current statewide civil fee schedule lists $120 to commence an action
by a plaintiff, petitioner, or appellant. The adult packet directs a person who
cannot afford filing fees to ask the clerk for an affidavit of inability to pay;
the local form name may vary.
The current order form states that the new name is valid for all legal documents
and includes Montana birth-record options. The adult should obtain certified
copies for identification and other record updates.
What trips people up
- The four weeks run before the hearing. Proof of publication or posting is
a prerequisite to the ordinary hearing. - Safety sealing is not a generic publication waiver. The petition must
allege probable cause of a safety risk and satisfy the debt/criminal-record
finding. - Corrections supervision is a different procedure, not a categorical bar.
The department receives service, may respond, and contacts victims after the
2025 amendment.
Common questions
Does Montana require a hearing?
Yes for the ordinary adult route. Section 27-31-203 requires the application to
be heard after proof of notice.
Can publication be avoided for safety?
Yes, if the court grants sealed-record treatment under § 27-31-201(3). The adult
must show probable cause that safety is at risk and satisfy the improper-purpose
finding.
Does Montana require fingerprints?
No fingerprint card or routine background-check package appears in the current
chapter or ordinary adult packet.
