Mail original documents that need an inmate's signature to the caseworker at St. Charles County DOC. Use this exact format on the envelope: SCCDOC - Inmate Name/Inmate Number C/O Caseworker, 301 N. Second Street, St. Charles, MO 63301. Including the inmate's name and number in the address line helps the facility route the paperwork to the right person.

Once St. Charles County DOC receives the document, staff will coordinate a time for the inmate to review and sign it. Don't expect this to happen immediately. The inmate won't be pulled on demand just because paperwork arrived. It gets handled through the facility's internal process.

Warning: Do not include a personal letter or other general inmate correspondence in the same mailing as transactional documents. Any general correspondence included will be destroyed.

Note: Inmates are not allowed to keep original documents sent through this process. Plan for the original to be handled for signing only, not stored with the inmate's property.
