Missouri — Sunshine Law (Chapter 610, RSMo)
3 business daysThe Missouri Sunshine Law (Chapter 610, RSMo)
In Missouri, government records are governed by the Sunshine Law (Chapter 610, RSMo). This law establishes that public records — defined as any document, recording, or data created or received by a government agency in the course of public business — are presumed to be open for inspection by the public unless a specific statutory exemption applies.
The law covers state agencies, county governments, city and municipal governments, school districts, public universities, and other public bodies. Federal agencies are governed separately by the federal Freedom of Information Act (5 U.S.C. § 552) — see our Federal FOIA Guide.
Response Deadline
Under the Sunshine Law (Chapter 610, RSMo), agencies in Missouri must respond to a public records request within 3 business days. This is the deadline for the agency's response — meaning they must acknowledge your request and either provide the records, estimate when they will be provided, or explain why records are being withheld. Complex requests may take longer to fully fulfill even after an initial response.
Fee Rules
Fee waivers at agency discretion. Missouri agencies may charge for the actual cost of searching, reviewing, and copying records. Before producing records, agencies should inform you of any estimated fees. If the estimated cost is too high, you can narrow your request, negotiate, or request a fee waiver.
Use our Fee Waiver Language Builder to generate the exact language Missouri requests should include to seek a waiver.
How to Submit a Request in Missouri
- Identify the right agency — Requests must go to the specific agency that holds the records you want. There is no central Missouri records clearinghouse.
- Write your request — Be specific: describe the records clearly, include relevant dates, and cite the Sunshine Law (Chapter 610, RSMo). Use our Letter Generator to create a properly formatted request.
- Submit to the records custodian — Most agencies accept requests by email, online portal, or certified mail. Check the agency's official website for their preferred method.
- Track your deadline — Note the date you submitted and count forward 3 business days. If no response by then, follow up in writing.
Common Exemptions in Missouri
The Sunshine Law (Chapter 610, RSMo) identifies records that may be withheld. Common exemptions include:
- Records related to ongoing criminal investigations
- Personnel files and personal privacy information
- Attorney-client communications and legal strategy
- Trade secrets and proprietary business information
- Records protected by federal law (HIPAA, FERPA, etc.)
- Records relating to security systems and infrastructure
When an agency withholds records, they must cite the specific statutory provision. A vague claim of "confidentiality" is not sufficient. If you believe records have been improperly withheld, you have the right to appeal.
