Does an insurance policy pay natural death benefits if the death was a natural death?

All insurance policies have a section within them which defines important terms, and those definitions, for the most part, will control. Therefore, look to see whether the policy defines "natural causes". If there is no express definition in the policy, a court will generally look to the common meaning of the term (or, if the term has been defined in prior cases, it will likely adhere to that precedent).

All of that said, if by "natural death" you mean old age, and barring other circumstances that you have not mentioned, the company will likely pay benefits. This of course also assumes that the policy was in force at the time of death.
