Ex-spouse died suddenly before the final QDRO was signed by court. The Pension plan involved was a SINGLE LIFE ANNUITY with only benefit to surviving spouse or ex-spouse with QDRO order. The Pension plan administrator approved the QDRO and it was sent back to be signed by lawyers, participant, alternate payee, and court. Is this QDRO now invalid, or does the alternate payee (ex-spouse) still have a right to fight for benefit with another lawyer?
