Another beneficiary contestment

Hi guys, As you might know I am contesting the beneficiary change (from 1995) of my late father (I was his original beneficiary). Currently, his ex wife (they divorced in 1999) is listed as his beneficiary. I believe that I was change back to beneficiary in 1999 (the year they were divorced and the year I turned 1 and that either the local represenative or the home office has misplaced this amendment and never had it recorded. The insurance company said that I can also file a claim for the policy even though I am not who they show as beneficiary. You see I have the original policy and I am his only relative therefore I am supposed to be the only person who can get certified death certificates. They of course want me to send them these things. Does this sound fishy to anyone else? I am kind of wondering how hard they are really going to look for the andquot;lostandquot; amendment? If it is found would they not be considered negligent for losing it and making me go through all of this? Also they sent my attorneys a copy of the beneficiary form that changed my dad's ex-wife to beneficiary. It also looks a little strange to me. My step-mother filled out the entire form. My dad only signed the bottom. Also he checked boxed to change the billing address and the beneficiary on the same form. I would hope my step mother would not have done this but at this point I am not putting anything past her. How do I know that my dad didn't think he was signing a change of address form and then she went back and changed herself to beneficiary before it was mailed off? I mean this women truely is evil and she knows this money is intended for me (my father's only child and basically his only living relative) Also would this matter to a court. I have a hand written letter from my step-mother that she wrote when she left my father. My dad had to go out of the state for a week for training for work. I was 17 and was staying at home with my step mother. I went to school on Mon. and when I came home there was nothing in my house except for this note. She took all the furniture, the dishes, even all the food. It was this note and a phone in the floor. In the note she repeatedly states she doesn't want anything but what she has already taken. She goes on to state that I won and now I have my daddy's time, house, and money. Does this letter mean anything? She also requests him to lie (which he did) and say they have been seperated for a year so that their divoce would go through immediatly. They were only married for 3 1/2 years.
