Term insurance work in a similar way as other types of insurance and giving you full return if you up to date it in regular interval and not if you didn't fill the premiums regularly.
The simplest form of term life insurance is for a term of one year and other most common term life insurance policies are 10, 15, 20 and 30 years. You can fix the premium monthly, bimonthly or annually.
