If you already have a policy in place, are you paying too much?  The answer is probably "yes".

Why? because premium rates have dropped substantially over the past few years and it is extremely unlikely that your insurer will have adjusted your payments.

You may not have benefited from a full comparison of insurance company premiums at inception of the policy.

Policies can be single or joint policies; in the case of joint policies the policy will pay out at the death of either policyholder, but it does not pay out twice if both policyholders die.
