How to Legally Change a Name in Montana

Step 1 – Fill Out Forms

Once they have the necessary forms, the petitioner can complete the top section of the Notice of Name Change Hearing and Order Setting Name Change Hearing.

Those changing their name for their own personal safety should instead complete the Name Change (Under Sealed Record) packet.[1]

Step 2 – File Documents

The petitioner must take their documents and a self-addressed stamped envelope to the Clerk of District Court’s office in the county where they live for filing.[2] There will be a filing fee. Those who cannot afford the fee can request a waiver by submitting an Affidavit of Inability to Pay.[3]

Petitioners must request that the Clerk of Court stamp their copies of each document as “Filed” and request two copies of the Order Setting Hearing via mail.

Step 3 – Publish Notice

The court will send the petitioner the Order Setting Hearing and Notice of Hearing with publication instructions. It must be published for four consecutive weeks before the hearing date, and proof of publication must be collected.[4]

Step 4 – Fill Out Order

Before the hearing takes place, the petitioner must prepare the Order Changing Name by filling in as many fields as possible and making a copy.

Step 5 – Attend Hearing

The petitioner must bring their stamped documents, proof of publication, and the two copies of the Order Changing Name to their hearing.[5] The judge may ask the petitioner questions regarding the name change, and if satisfied, they will sign the Order Changing Name.[6]

The signed Order must be brought to the Clerk immediately after the hearing. The petitioner must request certified copies of the document to change their name on their driver’s license, Social Security card, and other relevant documents.

Marriage and Divorce

Individuals may change their name via their marriage license or equivalent documentation.[7] A divorce decree (or equivalent) may be used by individuals who want to restore their pre-marriage name.[8]
