In order to make a claim on a life insurance policy you will need the life insurance policy, or policy number, and an official death certificate of the insured person on the life insurance policy.
There are instructions stated in the life insurance policy explaining how to make a claim on the life insurance policy.
You may also want to call the life insurance company and explain that there has been a death of an insured and ask specifically what you need to do in order to make a claim on the life insurance policy.
Once the insurance company has all of the required information and documentation, it usually takes about 2-3 weeks for the beneficiary to receive the death benefit check.
