28 CFR 542.16 - Assistance.
(a) An inmate may obtain assistance from another inmate or from institution staff in preparing a Request or an Appeal. An inmate may also obtain assistance from outside sources, such as family members or attorneys. However, no person may submit a Request or Appeal on the inmate's behalf, and obtaining assistance will not be considered a valid reason for exceeding a time limit for submission unless the delay was caused by staff.
(b) Wardens shall ensure that assistance is available for inmates who are illiterate, disabled, or who are not functionally literate in English. Such assistance includes provision of reasonable accommodation in order for an inmate with a disability to prepare and process a Request or an Appeal.
