70 O.S. § 17-105 provides that the sixty (60) day application for retirement deadline can be waived by application to the Executive Director. The application for waiver must state the reason for the request and the decision to grant or deny the waiver shall be made by the Executive Director. The application for waiver must be received by TRS no less than 15 days prior to the date of retirement. Upon request of the member, the Board may review at its next regular meeting any denial of a waiver by the Executive Director. Members are presumed to be familiar with the plan provisions and aware of the notice requirement and the Executive Director will grant the waiver only for good cause shown. Good cause is generally shown in cases of an unforeseen hardship, such as illness of the member or a member's family, a reduction in force, layoff of employment, or other unexpected change in job status. Good cause is also generally shown in cases of error or delay on the part of the employer and the error or delay is due to no fault of the member.
