Idaho-Specific Details
Idaho adult name change petitions are filed in the District Court of your county of residence. Major filing locations include the Ada County District Court in Boise (Fourth Judicial District), the Canyon County District Court in Caldwell, and the Bonneville County District Court in Idaho Falls (Seventh Judicial District). Filing fees range $150–$450 depending on the county. Idaho courts apply a strict "good cause" standard for name changes — you should be prepared to articulate a substantive reason in your petition, as judges may deny petitions they consider frivolous or insufficiently justified.
Publication is required for four consecutive weeks in a county-approved newspaper at $40–$200. The Idaho Statesman in Boise and the Idaho Press in Nampa handle most general-circulation publications, with smaller counties relying on community weeklies. Idaho also requires petitioners to swear to a non-fraudulent purpose and to disclose any criminal history. The Idaho Transportation Department's Division of Motor Vehicles does not currently allow self-attestation for gender marker changes or offer a nonbinary "X" option on licenses, so additional documentation is required for gender designation updates.
For your license update, Idaho's DMV charges $30 and does not require an appointment at most county sheriff's office driver licensing windows (Idaho processes licenses through county sheriffs, not a centralized state DMV) — walk-ins are accepted. Ada County's Boise office and the Canyon County office see the heaviest volume; offices in Bonneville and Twin Falls counties process updates faster. Bring your certified court order, current license, and updated Social Security card. Your new license arrives by mail in 1–4 weeks. Estimate your total at our cost calculator.

Marriage Name Change in Idaho
In Idaho, your certified marriage certificate is your legal name change document — no court order, no publication, just the $30 ITD license fee plus certified copies.
After getting married in Idaho, you can change your name using your certified marriage certificate as legal proof. This is the most straightforward type of name change since no court petition is required.
What you'll need: A certified copy of your Idaho marriage certificate from the county where you were married. If married outside Idaho, you'll need a certified copy from that state's vital records office.
Step-by-step process:
- Update Social Security. Visit your local Social Security office first. Bring your current Social Security card, driver's license or passport, and certified marriage certificate. This update is free and takes 2-4 weeks.
- Update Idaho Driver's License. Once you receive your new Social Security card, visit the Idaho Transportation Department with your current license, certified marriage certificate, new Social Security card, and $30 fee.
- Update Other Documents. Update your passport, voter registration, bank accounts, and other important documents using your marriage certificate as proof.
The entire marriage name change process typically takes 4-6 weeks to complete all major documents. Your certified marriage certificate serves as permanent legal proof of your name change — keep multiple copies for various agencies and institutions.
Idaho allows you to take your spouse's last name, hyphenate both names, or keep your prior name. Whatever you choose, make sure it's consistently reflected on your marriage certificate before you begin updating other documents.

Divorce Name Change in Idaho
Idaho offers two paths: name restoration written into your divorce decree (free, easy), or a separate Petition for Change of Name filed at District Court after the divorce is final.
If you want to restore your prior name after divorce in Idaho, you have two main options: include the name restoration in your divorce decree or file a separate petition later.
During your divorce: The easiest approach is to request name restoration directly in your divorce proceedings. Your attorney can include language in the divorce decree that restores your prior name. This avoids a separate court petition and additional fees later.
After your divorce: If your divorce decree doesn't include name restoration, you'll need to file a separate petition for name change in Idaho district court. This follows the same process as a court-ordered name change, including filing fees, publication requirements, and a court hearing.
Your divorce decree with name restoration language serves as legal proof for updating all your documents. The wording typically states something like "Petitioner's former name of [prior name] is hereby restored."
Once you have your divorce decree with name restoration, follow the same update process as marriage name changes: start with Social Security, then your Idaho driver's license, then other documents. The divorce decree replaces your marriage certificate as proof of the name change.
Some Idaho counties may have specific forms or requirements for name restoration in divorce decrees. Check with your local district court or consult with your divorce attorney to ensure proper wording is included.

Court-Ordered Name Change in Idaho (Adult)
For any name change that's not through marriage or divorce. File a Petition for Change of Name at your county District Court — $150–$450 filing fee, 4-week publication, and Idaho applies a strict "good cause" standard.
For adult name changes not related to marriage or divorce, Idaho requires a court petition through your local district court. This process involves more steps and requirements than marriage-based changes but gives you complete flexibility in choosing your new name.
Step-by-step court process:
- File Your Petition. File a Petition for Change of Name at your county's district court. Include your current name, desired new name, and reasons for the change.
- Pay Filing Fees. Pay the court filing fee, which varies by county. Contact your local district court clerk for current fee schedules.
- Publish Notice. Publish notice of your name change petition in a local newspaper for several consecutive weeks. This allows potential objections to be raised.
- Attend Your Hearing. Attend your scheduled court hearing. The judge will review your petition and any objections, then decide whether to grant the name change.
- Receive Your Order. If approved, you'll receive a certified copy of the court order granting your name change. This serves as legal proof for updating all documents.
Required documents for your petition:
- Completed Petition for Change of Name form
- Valid photo identification (driver's license or passport)
- Birth certificate or proof of citizenship
- Background check or criminal history (some counties require this)
- Filing fee payment
Publication requirements: Idaho law requires public notice of name change petitions to protect against fraud. You'll need to publish notice in a newspaper of general circulation in your county for a period specified by the court, typically 3-4 consecutive weeks. Publication costs vary by newspaper but typically range from $50-150.
Common reasons courts approve: Personal preference, cultural reasons, religious reasons, professional reasons, or to match family naming conventions. Idaho courts generally approve name changes unless there's evidence of fraud or intent to avoid legal obligations.
The entire court-ordered name change process typically takes 6-10 weeks from filing to receiving your final order, depending on publication requirements and court scheduling in your county.

Minor Name Change in Idaho
Idaho requires court approval for any minor name change. Both biological parents must consent, and minors age 14 or older can file the petition themselves with parental consent.
Changing a minor child's name in Idaho requires a court petition similar to adult name changes, but with additional requirements for parental consent and consideration of the child's best interests.
Who can file: Either parent, a legal guardian, or the minor themselves (if age 14 or older) can petition for a minor's name change. The process must be filed in the county where the child resides.
Consent requirements:
- Both parents living: Both biological parents must consent to the name change, even if one parent doesn't have custody
- One parent deceased: The surviving parent can petition alone with proof of the other parent's death
- Unknown parent: If one parent's whereabouts are unknown, the court may require efforts to locate them or may proceed without their consent
- Adoption scenarios: Different rules apply when adoption is involved — consult with the court about specific requirements
The petition must demonstrate that the name change is in the child's best interests. Common approved reasons include: matching the family name after remarriage, cultural or religious reasons, avoiding confusion or embarrassment from the current name, or safety concerns.
Additional requirements for minors:
- Child's birth certificate
- Consent forms from both parents (notarized)
- If the child is 14 or older, their written consent
- Proof of current custody arrangements
- School records showing current name usage
Publication requirements apply to minor name changes just as with adult changes. However, some judges may waive publication if both parents consent and there are no apparent objections.
Court hearings for minor name changes often involve questioning about the parents' motivations and ensuring the change truly serves the child's best interests. Be prepared to explain your reasoning clearly and provide any supporting documentation.

Gender Identity Name Change in Idaho
Idaho recognizes name changes for gender identity through the standard court process, but the ITD does not allow self-attestation or a nonbinary "X" marker — gender marker updates require a court order or amended birth certificate.
Idaho recognizes the right to change your name as part of gender identity affirmation. The process combines a standard court-ordered name change with additional considerations for updating gender markers on various documents.
Name change process: Follow the same court petition process described above for adult name changes. Your reason for the name change can simply state that the new name better reflects your gender identity. Idaho courts generally approve these petitions when properly filed.
Gender marker changes: Updating the gender marker on your documents involves separate processes beyond the name change:
Idaho driver's license: The Idaho Transportation Department may require a court order or amended birth certificate to change gender markers on licenses and state IDs. Contact your local ITD office for current requirements, as policies can evolve.
Birth certificate: Idaho allows gender marker changes on birth certificates through a court order. You'll need to petition the district court with appropriate documentation, which may include medical certification of gender transition. The court order can then be used to request an amended birth certificate from Idaho Vital Records.
Federal documents: Your court order for name change helps update federal documents like your Social Security record and passport. Social Security Administration and State Department have their own policies for gender marker updates that may require additional documentation.
Tips for the process:
- Consider filing for both name change and gender marker change simultaneously if needed
- Keep multiple certified copies of all court orders — you'll need them for various agencies
- Update your name with Social Security first, as other agencies verify against SSA records
- Some counties may be more familiar with these petitions than others — consider consulting with local LGBTQ+ organizations for referrals
The timeline for gender identity-related name changes follows the same 6-10 week process as other court-ordered changes. Having proper documentation and legal guidance can help ensure a smooth process through Idaho's court system.
