I am the second wife. I was designated as beneficiary on husbands plan when we married (2012), and one year later I became vested as the beneficiary (2013) In 2014 his ex wife got a QDRO in state court, designating her as surviving spouse. I objected as I did not sign waiver. She had not been awarded surviving spouse designation in their PSA, it simply said 50% of the benefits accrued on the date of divorce. The Plan administrator subsequently confirmed their view that the PSA itself was not a QDRO. The question is - who's survivor designation is correct? I am still the current beneficiary on the record of the plan.
