What are my legal rights when my ex wife passed away and I am still listed as her beneficiary? 1 Answers as of February 16, 2012

Recently my ex wife passed away. Although we were divorced, we remained friends; however she did change her will and update/change her beneficiaries. She opened an annuity several years before our divorce (this money was from a pre-taxed retirement fund), my ex wife never changed me as the beneficiary. I was contacted by the financial organization stating that I was the beneficiary but they had been informed of our divorce. They told me that they needed to verify the correct beneficiary and want a copy of our divorce papers, specifically the pages that cover investments, savings, annuities, retirement plans. I have included the statements below from our divorce papers that cover savings/investments, etc. Can you tell me if I may still be considered the beneficiary? We were married in South Carolina, she moved to Georgia after separation and our divorce was finalized in Georgia. When she passed away she was a resident of South Carolina. Thank you in advance for your time.
