In order to buy a life insurance plan you will have to fill out an application for coverage. There are basis questions asked about your age, gender, health, and tobacco use, etc.
However, there are some plans called Guaranteed-Issue that offer you coverage with NO health exam required and NO health questions asked.
These plans are referred to as Guaranteed-Issue because they guarantee your approval for life insurance regardless of your health status.
If you meet the age requirements for acceptance (eg.: 45-85) you are guaranteed coverage as long as you can pay the premiums and you live in a state where the insurance company is licensed to do business, and offers the plan.
However, guaranteed life insurance plans usually offer a limited amount of coverage, perhaps up to $25,000 or less.
Here's how to get a no question life insurance policy.
