Missouri adult name changes are governed by RSMo §§ 527.270 through 527.290 and filed in the circuit court of the petitioner's county of residence.

1. File the Petition

  • File with the circuit court clerk; filing fee is approximately $50–$200 (St. Louis County: ~$162; Jackson County: ~$143).
  • Must be a Missouri resident (no fixed minimum).
  • 2. Publication

  • Publish notice once a week for three consecutive weeks in a newspaper of general circulation in the county (RSMo § 527.290).
  • The last publication must occur at least 20 days before the order is entered.
  • Cost: $50–$200.
  • Waiver available where publication would put the petitioner at risk (RSMo § 527.290.2).
  • 3. Disclosures
