This policy applies to all DSS and DMMA case records.
Case records are kept in locked file cabinets except when the files are in use. The records must be returned to the files before the office closes for the day. [Electronic case records are maintained in a secure data system.]
Records sent to another office may be sent in the custody of a Division employee or by Department messenger mail. [DSS and DMMA records in electronic form are not transferred between offices.]
