I want to make sure my understanding of the QJSA rules for DC plans is accurate. As I read Rev. Rul. 2012-3, if a plan offers a single life annuity or a QJSA as the default form of distribution in the absence of a participant election, and also offers a lump sum, spousal consent is not required if the participant elects the lump sum prior to the participant's annuity starting date. Assume the plan has no annuity investments, and thus, e.g., Situation 2 in Rev. Rul. 2012-3 would not apply.
