Idaho Name Change Laws: How to Legally Change Your Name

Idaho's name-change process runs through a single chapter of the Idaho Code, filed as a petition in district court, with a hearing, mandatory four-week newspaper publication, and a $166 filing fee. A companion section bars using a name change to escape sex-offender-registration duties and requires the court to notify the state registry whenever a registrant's petition is granted.

Idaho has no dedicated statute covering either divorce name restoration or marriage-based name changes. Both are handled by practice rather than a distinct Code section, which matters for how a reader should plan a divorce or marriage-related name change in Idaho.

How to Legally Change Your Name in Idaho

An adult or minor's petition is filed in district court, in the county where the petitioner resides, under Idaho Code §7-802. The Idaho Court Assistance Office maintains a statewide set of forms for the process, including a General Civil Case Information Sheet, an unredacted and a redacted Petition for Name Change, a Notice of Hearing, and a Judgment for Name Change.

The filing fee is $166. Idaho Code defines an "emancipated minor," for purposes of this chapter, as any minor who has been married or is in active military service; an emancipated minor signs and files their own petition the way an adult would, rather than needing a parent or guardian to file on their behalf.

Changing a Minor's Name in Idaho

For a minor under 18 who is not emancipated, one parent or a guardian signs the petition. The petition must specify the other parent's name and address if living, or, when a guardian is filing, the names and addresses of the parents or grandparents if living. The statute text available does not set out a separate best-interest standard beyond this notice requirement.

Restoring a Former Name After Divorce

Idaho has no statute dedicated to restoring a name after divorce. Idaho Code §32-716, in the dissolution title, covers only reconciliation-conference procedure and timing, with no name-restoration content, and a broader search of Idaho's domestic-relations chapters found nothing else on point.

In practice, per Idaho legal-aid resources, courts allow a name restoration request to be written directly into the divorce decree even without a specific statute authorizing it, which avoids a second filing. A spouse who does not raise the request at the time of divorce can instead file the ordinary Chapter 7-802 petition afterward, paying the standard $166 fee. Readers planning an Idaho divorce should raise the name-restoration request with the court or their attorney at that time rather than assuming it happens automatically.

Publication Requirements

Notice that a petition has been filed must be published, and a hearing is set at a court-appointed time where any person who can show cause may object. The Idaho Court Assistance Office's own instructions describe weekly publication running four consecutive weeks. No domestic-violence or confidentiality waiver of this publication requirement was found on the Idaho Court Assistance Office's name-change page; anyone with a safety concern about publishing their name-change filing should raise it directly with the district court.

Sex Offender Registry Restrictions

Idaho Code §7-805 bars a name change sought with intent to avoid a sex-offender-registration duty under Idaho's sex-offender registration law, and bars a court from granting any name change that would relieve a person of that registration duty. Where a name change is granted to someone who remains a registrant, the court must notify the Idaho State Police Central Sexual Offender Registry, including the person's previous name, new name, Social Security number, date of birth, and last known address. This provision was added in 1998 and amended in 2000, and remains current law.

Marriage-Based Name Changes in Idaho

Idaho has no statute dedicated to a marriage-based name change. A spouse who wants to adopt a new name at marriage does so by custom, presenting a marriage certificate to update records with agencies like the Social Security Administration and the DMV rather than filing a court petition. See name change after marriage for the federal-level steps involved.
