How difficult is it to rival a life insurance claim?

My father informed me that he wanted to make me the beneficiary of his life insurance policy 11 days before he passed away. He did not have a chance to make the update with MetLife. So, my step-mother is still listed as the beneficiary and all I have as proof that he wanted me to be the beneficiary and NOT her is an email that he sent to me. We live in Arkansas and I am my father's only child and closest living relative.
What are my chances of getting the money?
