Can my former spouse, who is the Alternate Payee, designate a beneficiary for his/her share of my pension in the event he/she dies before me?

No, the Alternate Payee’s portion of the pension has no survivor benefit. If the Alternate Payee dies prior to the Participant’s retirement, or any time after the commencement of benefits, that share will revert back to the Participant. The Participant will be required to produce a copy of the Alternate Payee’s death certificate.
