Which type of insurance requires evidence of insurability at all times?

Universal life insurance requires evidence of insurability at all times because it is designed to be flexible in terms of premium payments and death benefits, which can change over time. This flexibility often means that when an insured individual wants to increase the death benefit or if they are seeking to renew coverage, the insurer will require proof of insurability to assess the current risk based on the insured's health status.

In contrast, guaranteed issue insurance typically does not require any evidence of insurability, making it accessible for those who may have health issues that would make traditional insurance difficult to obtain. Other types, like term life and whole life insurance, may have different underwriting requirements but usually only need evidence of insurability at the time of application or conversion, rather than continuously throughout the policy's life.
