The basic principles of insurance are:
Utmost good faith: Both the insurer and the insured must disclose all material facts honestly.
Causa proxima (Proximate cause): Insurance policies must cover losses that result directly from a specific cause.
Indemnity: Insurance contracts are designed to restore the insured to the same financial position after a loss, without profit.
The Principle of insurer interest is not typically a part of the basic principles of insurance; it relates more to the financial interest of the insurer, which is not a standard principle in insurance contracts.
