Sealing a divorce or civil file in Missouri
Missouri closes old divorce pleadings by statute and keeps new ones open with redaction. RSMo 452.430 provides that pleadings, other than the interlocutory or final judgment, in a dissolution, legal separation or modification proceeding filed before August 28, 2009 and less than 72 years before the request are subject to inspection only by the parties, an attorney of record, the family support division, the attorney general, a title insurer, or a person with a court order for good cause shown. For cases filed on or after that date the file is open under Court Operating Rule 2, as restructured effective July 1, 2026, and protection comes from redaction: RSMo 509.520 keeps Social Security numbers, account numbers, birth dates and minors' names off public filings and puts the employer and Social Security data on a confidential case filing sheet that the court may release only for good cause shown.
Beyond those rules, a document is closed only by court order, and from July 1, 2026 the standard for sealing a record is set by Supreme Court Rule 55.0275. The statute is at revisor.mo.gov.

Research Notes
- Start with the court and the originating agency. Expungement or sealing requests are often handled through the court that heard the case, sometimes with supporting records from police, prosecutors, or corrections agencies.
- Terminology differs by state. Some jurisdictions use terms such as sealing, set-aside, vacatur, dismissal relief, or nondisclosure instead of expungement.
- Verify current law. Eligibility rules can change through legislation or court decisions, so always confirm the current process before relying on older instructions or third-party summaries.
- Understand downstream effects. Even after record relief, treatment of court, police, private-background check, and federal records may differ depending on the system involved.
