Insurable Interest, Indemnity, and Subrogation

Three interlocking principles keep property insurance from becoming a wager. First, insurable interest: the insured must stand to suffer a genuine financial loss. The timing rule is a classic exam contrast — life insurance requires insurable interest only at policy inception, while property insurance requires it at the time of loss. Sell the house before the fire and you recover nothing, even though you had interest when the policy was written. Interest arises from more than simple ownership: a mortgagee has insurable interest to the extent of its loan, a lessor retains interest in leased property, and a trustee holding legal title plus a fiduciary duty to preserve trust assets has insurable interest in trust property. Second, indemnity: recovery equals the actual financial loss sustained, capped at policy limits and subject to deductibles — the insured must never profit from a loss. Indemnity explains ACV settlement defaults, other-insurance clauses, salvage rights, and subrogation. When two policies cover the same loss, other-insurance provisions decide priority: some share pro rata by limits, while the more general policy typically carries an excess clause so the more specific policy pays first. Valued policies and life insurance are the recognized exceptions because they pay a fixed sum rather than measured loss. The standard (union) mortgage clause adds a twist: it gives the mortgagee what amounts to an independent contract with the insurer, so arson or misrepresentation by the insured does not defeat the mortgagee's right to recover up to its interest. Third, subrogation: once the insurer pays a covered loss caused by a third party, it stands in the insured's shoes against the wrongdoer up to the amount it paid — pro tanto, to that extent only. Subrogation prevents double recovery, shifts the ultimate loss to the responsible party, and caps the insurer's recovery at its own payment; anything above belongs to the insured. The insured must not impair these rights: a post-loss waiver of recovery against the wrongdoer requires insurer consent, though a written pre-loss waiver (such as in a lease) is generally honored. Related equitable limits include the made-whole doctrine, which in many states lets the insured be fully compensated before the insurer collects, and the anti-subrogation rule, which bars the insurer from subrogating against its own insured.
