What mean by Paid-up policy | what is a Paid-up policy?

Once you pay the premiums on a life insurance policy for 3 full years, the policy does not become wholly void even if no subsequent premiums are paid. Such policies are known as paid-up policies. In such cases, the sum originally assured is reduced to a sum bearing the same ratio to the full sum assured as the number of premiums actually paid to total number of premiums originally stipulated as payable under the policy.

If 6 out of the originally stipulated 30 premiums are paid, the sum assured under a paid-up policy would still be 20 percent of the original sum assured by the policy.
