Kan. Admin. Regs. § 44-12-506
In all matters an inmate shall respond to officials when addressed by the name under which he was committed to the custody of the secretary of corrections until discharged from sentence. An inmate shall be referred to in all official transactions, and all correspondence to and from the inmate, under the name used in the journal entry of convictions and commitment throughout his or her period of incarceration. In the event of a legal name change, the records may reflect the new name as an alias and the inmate may use the alias name in parentheses after the conviction name. All directives to, references to, or orders to an inmate by his convicted name shall be complied with regardless of the fact that he or she may have changed his or her name. No charge shall be made against any inmate under this rule because the inmate is the addressee of any mail, phone call, document or other communication under the non-conviction name unless it is alleged and proven that the inmate was knowing and willing conspirator or instigator of such use of non-conviction name. Violation of this rule shall be a class II offense.
