Do you know where your Life insurance policy is?

My Mother ped away and I was unaware that I was on her policy as beneficiary.I could not find the policy after her death, and signed a "lost policy" doent at the funeral home.Moms premiums and the amount paid differed by $5000.00 but I could not argue the point.Do you know where the policy is and if you are the beneficiary?You need to.
