What rights do you have over a life insurance policy taken out by your parents while you were an adult?

If your parents took out a life insurance policy and paid for it, the policy belongs to them and even if you are the person whose life is insured, that does not give you rights over that policy. I am not entirely sure why your parents would feel the need to have life insurance for their adult progeny, but possibly they are concerned that if you were to suffer a tragic premature death, they would be stuck with funeral expenses that they could not afford to pay unless they had an insurance policy to help them.
