Indemnity

Indemnity is the idea that insurance is compensation, not a windfall. The payout is meant to put you back where you were the moment before the loss — covering the depreciated value of the car or the cost of repairs — but not to leave you better off. This single principle shapes most of how motor claims are settled.

Several familiar rules flow directly from it. A write-off pays market or retail value, not the original purchase price, because that is your true position. Betterment can apply when a repair leaves the car better than before (a new part replacing a worn one). And the average clause reduces a claim when you under-insured, because you only paid to cover part of the value.

Agreed value is a deliberate, contracted exception for classics and collectibles, where a fixed sum replaces the strict indemnity calculation. For everything else, expecting a claim to do more than restore your pre-loss position is the most common source of disappointment — indemnity is the yardstick the insurer actually uses.
