Life Insurance Systems

Learn the business fundamentals of Life Insurance, including policy types, stakeholders, policy lifecycle, beneficiaries, nominations, premium payments, maturity, surrender, and death claim settlement.

Life Insurance is one of the most important financial products offered by insurance companies. It provides financial security to a policyholder's family or dependents in the event of the insured person's death.

Unlike general insurance, life insurance focuses on protecting human life while also serving as a long-term financial planning and wealth creation tool.

What is Life Insurance?

Life Insurance is a contract between a customer and an insurance company.

The policyholder pays premiums regularly, and in return, the insurance company promises to pay a specified amount (called the Sum Assured) to the nominee or beneficiary if the insured person dies during the policy term.

Some policies also provide maturity benefits if the insured survives the policy term.

Why Do People Buy Life Insurance?

People purchase life insurance for many reasons:

  • Financial protection for family
  • Income replacement
  • Children's education
  • Retirement planning
  • Wealth creation
  • Tax benefits
  • Loan protection
  • Estate planning

  • After eight years, he unfortunately passes away.
  • His nominee submits a death claim.
  • The insurer verifies the documents.

This demonstrates the primary objective of life insurance—providing financial protection to dependents.
