How to Change Your Name in Wyoming — Complete 2026 Guide

After getting married in Wyoming, your certified marriage certificate serves as legal proof of your name change — no court petition required. This makes marriage the most straightforward path for how to change your name after marriage in Wyoming.

Start by ordering certified copies of your marriage certificate from Wyoming Vital Statistics Services or the county clerk where you were married. You'll need multiple certified copies since most agencies require originals. The fee is $8 per certified copy from Vital Statistics Services.

Your first stop should always be the Social Security Administration. Update your Social Security card within a few weeks of your marriage, as this creates the foundation for all other name changes. Bring your driver's license, certified marriage certificate, and Social Security card to your local SSA office. The new card arrives in 2-4 weeks at no charge.

Next, update your Wyoming driver's license at the Department of Transportation (WYDOT). Wait 24-48 hours after your SSA visit to ensure their system reflects your updated name. You'll need your current license, certified marriage certificate, new Social Security card, and proof of Wyoming residency. The replacement fee is $10, and your new card arrives by mail in 1-4 weeks.

For your passport renewal, you can use Form DS-82 if your name change occurred within one year of passport issuance. Otherwise, you'll need to apply in person using Form DS-11. Both require your certified marriage certificate as proof of the name change.

Remember to notify the IRS using Form 8822, update your voter registration, and contact your banks and credit card companies. Most financial institutions accept a certified marriage certificate as proof of your name change.

If you want to return to your prior name after divorce in Wyoming, the easiest method is to include the name restoration in your divorce decree. Wyoming courts routinely grant requests to restore a prior name as part of the divorce proceedings — no separate petition required.

When filing for divorce, include language in your petition requesting restoration of your prior name. The final divorce decree will contain an order stating your name is legally changed back to your prior name. This decree serves as your legal proof of name change for all agencies.

If your divorce is already final and the decree doesn't include name restoration, you'll need to file a separate court petition for a name change. This follows the same process as a general court-ordered name change, including publication requirements and court fees.

Once you have your divorce decree with name restoration, follow the same document update process as marriage name changes: start with Social Security, then your Wyoming driver's license, passport, and other documents. The divorce decree replaces the marriage certificate as your proof of name change.

Some agencies may require a certified copy of the divorce decree rather than a photocopy. Order multiple certified copies from the clerk of court where your divorce was finalized. The fee varies by county but typically ranges from $5-15 per copy.

For adults seeking a complete name change in Wyoming (not through marriage or divorce), you'll need to petition the district court in your county of residence. Court ordered name change Wyoming procedures are standardized across the state but fees vary by county.

The entire court-ordered name change process typically takes 6-10 weeks from filing to final order. Once you have your court order, you can begin updating all your documents using this as legal proof of your name change.

Wyoming courts generally approve name change requests unless there's evidence of fraud, intent to avoid debts, or the new name would be confusing or inappropriate. The judge has discretion to deny requests that don't serve a legitimate purpose.

Changing a child's name in Wyoming requires a court petition filed by the parent or legal guardian. Child name change Wyoming requirements include additional protections since minors cannot petition for themselves.

If both parents have legal custody, both must consent to the name change or appear in court. If you're filing without the other parent's consent, you'll need to prove they've abandoned the child, had their parental rights terminated, or that the name change serves the child's best interests despite their objection.

The petition must include the child's current name, proposed new name, reason for the change, and information about both parents. You'll need to serve notice to the non-petitioning parent unless their whereabouts are unknown or parental rights have been terminated.

Publication requirements for minor name changes follow the same rules as adult changes — once weekly for four consecutive weeks in a local newspaper. However, some courts may waive publication if both parents consent and there are safety concerns.

At the hearing, the judge will consider the child's best interests, including their age and preference if old enough to express one. For teenagers, courts often give significant weight to the minor's wishes regarding their name change.

Once approved, the court order allows you to update the child's Social Security card, birth certificate (if born in Wyoming), school records, and other documents. The process typically takes 6-8 weeks from filing to final order.

If the child was born outside Wyoming, you'll need to check that state's requirements for updating their birth certificate with the new name.

Transgender individuals seeking a name change in Wyoming follow the same court petition process as other adults, but may face additional considerations when updating gender markers on official documents.

For the name change itself, file a standard adult petition for change of name with your district court. Wyoming courts cannot deny name change petitions based solely on gender identity, and the process follows the same publication and hearing requirements as any adult name change.

When updating your Wyoming driver's license, gender marker changes may require additional documentation beyond your name change court order. Contact WYDOT directly to ask about current requirements, as policies can change. Some transgender individuals find it helpful to update their name first, then pursue gender marker changes separately.

For your birth certificate, if you were born in Wyoming, the state allows gender marker changes with appropriate medical documentation. Contact Wyoming Vital Statistics Services for current requirements and forms. If born in another state, you'll need to work with that state's vital records office.

Your updated name change court order will be sufficient for most agencies including Social Security, passport services, banks, and employers. The Social Security Administration allows gender marker updates through their standard process once you have supporting documentation.

Consider timing your document updates strategically. Many transgender individuals start with the court-ordered name change, update their Social Security records, then tackle driver's license and birth certificate changes. This ensures consistency across documents and reduces complications.

Wyoming's court system generally handles gender identity name changes respectfully and professionally. If you encounter any discrimination or unusual requirements, consider consulting with an attorney familiar with transgender rights in Wyoming.
