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 18) 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 "lost" 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.
