The statute, as written — Enrollment
Upon entering or reentering service, an employee shall file with the board such information as the board of trustees may require for enrollment and administrative purposes including a designation of a person or persons to receive any benefit that may be payable in the event of the employee's death. An employee becoming a member of the system shall also present at such time and in such form as the board prescribes, evidence of the employee's date of birth. No statement or record of age or birth made or presented by a member of the system may be impeached by the member or the member's successors in interest.
