Montana Title 19. Public Retirement Systems § 19-20-1007. Requirements for beneficiary designation to be effective

(3)  1(a) The retirement system is not responsible for verifying beneficiary information provided by a designator.

(b) The retirement system may accept or decline a beneficiary designation record pending receipt of required supporting documentation. However, if the retirement system accepts a beneficiary designation record pending receipt of supporting documentation, the beneficiary designation is not effective unless the retirement system receives all required supporting documentation within the required timeframe.

(c) If multiple beneficiaries are designated on a beneficiary designation record and the retirement system accepts the beneficiary designation as effective but later determines that one or more of the beneficiaries was not effectively designated or is not an eligible beneficiary at the time payment is to be made, the beneficiary designation will remain in effect with the ineffectively designated or ineligible beneficiaries deemed to have predeceased the member.
