How do I legally change my name in Colorado?

Federal & State Law Editorial TeamLast reviewed: 2026-05-17

Colorado adult name changes are governed by C.R.S. §§ 13-15-101 through 13-15-103 and filed in the district or county court of the petitioner's county of residence.

1. File the Petition

  • Complete JDF 432 (Petition for Change of Name — Adult).
  • File with the district or county court clerk; filing fee is approximately $86 in county court, $97–$224 in district court.
  • Petition must include current/proposed name, residence, and prior names.
  • 2. Fingerprint Background Check

  • Colorado requires fingerprint-based CBI and FBI background check for adult petitioners (C.R.S. § 13-15-101(2)).
  • Use a Colorado-approved Live Scan vendor (~$50). Court receives results.
  • 3. Publication

  • Publish notice in a newspaper of general circulation in the county three times before the order is entered (C.R.S. § 13-15-101(3)).
  • Cost: $50–$200.
  • Waiver available for safety (C.R.S. § 13-15-101(4)) and automatic waiver for petitioners changing their name to conform with gender identity (C.R.S. § 13-15-101(4.5)).
  • 4. Order

  • Court issues JDF 433 (Public Decree) or JDF 448 (Confidential Decree) depending on waiver.
  • 5. After the Decree

  • Certified copies ($20 each in district court).
  • File SSA Form SS-5 (free).
  • Update Colorado DL at DMV ($28.06), passport, voter registration, banks.
  • 6. Divorce-Based Restoration

  • C.R.S. § 14-10-120.5 allows restoration of a former name in the dissolution decree without separate proceeding.
