Insurance: nature, history and classification

1. Meaning and definition

Insurance is a way of spreading loss. Many people exposed to the same risk each pay a small sum, the premium, into a common fund. The few who actually suffer the loss are paid from that fund. The insurer does not prevent the loss; it shifts the money consequence of it from one person to the group.

For a long time Indian statute law had no general definition, and answers relied on textbook definitions. That changed with the Sabka Bima Sabki Raksha (Amendment of Insurance Laws) Act, 2025 (40 of 2025). It inserted clause (6D) in section 2 of the Insurance Act, 1938: “insurance business” means the business of effecting insurance contracts, and the Explanation defines an insurance contract as “the contract whereby the insurer, on payment of premium, undertakes to assume risk and to pay to the insured person an agreed compensation for loss, damage or liability arising from a contingent event” on the agreed terms. The Act came into force on 5 February 2026 (S.O. 490(E) dated 3 February 2026), except its section 25.

Older definitions are still useful in an answer. Section 3 of the Marine Insurance Act, 1963 defines marine insurance as an agreement by which the insurer undertakes to indemnify the assured against marine losses. Section 2(11) of the Insurance Act defines life insurance business as effecting contracts of insurance upon human life, including any contract whereby payment of money is assured on death (except death by accident only) or on the happening of any contingency dependent on human life.

2. Nature and essentials of an insurance contract

An insurance policy is a contract, so sections 10 to 30 of the Indian Contract Act, 1872 apply: offer (the proposal), acceptance, free consent, competent parties and lawful object. On top of those, insurance has its own features.

• Utmost good faith (uberrimae fidei). Each side must disclose material facts without being asked (Unit II).
• Insurable interest. The insured must stand to lose by the event; otherwise the policy is a wager, void under section 30 of the Contract Act (Unit II).
• Indemnity for property insurance. The insured is put back where he was, not better. Life and personal accident policies are not indemnity contracts because a life cannot be valued; they pay a fixed sum.
• A contingent event. The event insured must be uncertain, either as to whether it will happen (fire) or as to when (death).
• Premium as consideration, which must normally be paid before the risk starts (section 64VB of the Insurance Act).
• A standard form contract. The insured cannot negotiate terms, so courts construe doubtful clauses against the insurer who drafted them (contra proferentem).

The last point has Supreme Court authority. General Assurance Society Ltd. v. Chandumull Jain, 1966 INSC 38, AIR 1966 SC 1644, a Constitution Bench, held that a contract of insurance is to be construed like any other contract, by its words, and that where there is ambiguity the construction favourable to the insured is adopted because the insurer chose the language.

3. History of insurance in the world

• Marine insurance came first. Babylonian and Greek traders used bottomry: a loan on the security of the ship, repayable only if the voyage succeeded. Lombard merchants in Italian city-states in the fourteenth century wrote the first recognisable marine policies, and carried the practice to London (Lombard Street).
• Lloyd's. From about 1688 underwriters met at Edward Lloyd's coffee house in London, which grew into Lloyd's of London. English law on marine insurance was codified in the Marine Insurance Act, 1906, the model for India's 1963 Act.
• Fire insurance followed the Great Fire of London of 1666, which led to the first fire offices in the 1680s.
• Life insurance developed in eighteenth-century England (the Amicable Society, 1706, and the Equitable, 1762, which first priced premiums by age using mortality tables).

4. History and development in India

• 1818 — Oriental Life Insurance Company, Calcutta, the first life insurer in India, set up mainly for Europeans. Indian lives were charged extra.
• 1870 — Bombay Mutual Life Assurance Society, the first Indian life insurer, which covered Indian lives at normal rates.
• 1912 — Indian Life Assurance Companies Act and Provident Insurance Societies Act, the first statutes regulating life business.
• 1938 — the Insurance Act, 1938, a comprehensive law covering life and general business, still the principal Act today.
• 1956 — life business nationalised. About 245 Indian and foreign insurers and provident societies were taken over and merged into the Life Insurance Corporation of India under the LIC Act, 1956, from 1 September 1956.
• 1972 — general business nationalised by the General Insurance Business (Nationalisation) Act, 1972: 107 insurers were amalgamated into four companies (National, New India, Oriental and United India), with the General Insurance Corporation as holding company.
• 1993–94 — the Malhotra Committee recommended opening the sector to private and foreign participation and an independent regulator.
• 1999 — the Insurance Regulatory and Development Authority Act, 1999: private insurers allowed, foreign equity capped at 26%, the regulator established in 2000.
• 2015 — Insurance Laws (Amendment) Act, 2015 (5 of 2015, w.r.e.f. 26 December 2014): foreign equity to 49%, a new section 45 and new sections 38 and 39.
• 2021 — Insurance (Amendment) Act, 2021 (6 of 2021): foreign equity to 74% from 1 April 2021.
• 2025 — Sabka Bima Sabki Raksha (Amendment of Insurance Laws) Act, 2025: section 3AA allows aggregate foreign holding in an Indian insurance company up to 100% of paid-up equity, in force from 5 February 2026.

5. Classification of contracts of insurance

The Insurance Act now lists the classes. Section 2(5A), inserted in 2025, defines “class of insurance business” as life insurance business, general insurance business, health insurance business, re-insurance business, or any other class notified by the Central Government in consultation with the Authority. An Indian insurance company must still confine itself to one class (section 2(7A): its “sole purpose” is life or general or re-insurance or health business), so a single company cannot write both life and general business.

• Life insurance — a fixed sum on death or maturity: whole life, endowment, term, money-back, unit-linked, annuities (Unit III).
• General insurance — fire, marine, motor, engineering, liability, crop and miscellaneous. These are contracts of indemnity.
• Health insurance — defined in section 2(6C) as substituted in 2025: contracts providing sickness benefits or paying medical and health expenses, including personal accident and travel insurance.
• Re-insurance — insurance of insurers (below).

Other ways to classify: by subject matter (person, property, liability), by whether the contract indemnifies or pays a fixed sum, and by whether it is individual or group insurance.

6. Re-insurance and reinstatement (short note)

Re-insurance is a contract by which an insurer passes part of a risk it has accepted to another insurer, the re-insurer, in return for part of the premium. The original insured has no contract with the re-insurer and cannot sue it (compare section 11(2) of the Marine Insurance Act). Re-insurance lets a direct insurer write large risks without endangering its solvency. It may be facultative (risk by risk) or by treaty (a whole class). Section 101A of the Insurance Act requires Indian insurers to cede a percentage of general business to Indian re-insurers; the 2025 Act added the words “a minimum of” to that obligation. The General Insurance Corporation of India is the national re-insurer, and foreign re-insurers may open branches (net owned fund of at least ₹1,000 crore under section 6(2) as substituted in 2025).

Reinstatement has two senses. In fire insurance a policy may give the insurer the option, instead of paying money, to rebuild or replace the damaged property; once the insurer elects to reinstate, it must restore the property even if that costs more than the sum insured. In a second sense, “reinstatement of sum insured” means restoring the sum insured to its original figure after a claim, usually on payment of extra premium. A lapsed life policy is revived, not reinstated; revival is dealt with under premium (Unit II).

How this is examined

Recent papers ask: “Discuss the history and development of life insurance in India” (February 2025), short notes on classification of contracts of insurance (January 2026, February 2025), “Re-instatement and Re-insurance” (January 2026) and “History of marine insurance” (June 2025, February 2025). For the essay, open with the 2025 statutory definition, list the essentials, then run the Indian timeline and end with the 100% foreign investment rule now in force. For the marine history note, use section 3 above and the marine notes in Unit V.
