The Fire Next Door: Indemnity, Subrogation, and a Stale Named Insured
Mia owns a duplex in Hilo and rents the lower unit to Kenji, whose unattended cooking starts a fire. The fire destroys Mia's upper unit and spreads to Lani's house next door. Lani carries an HO-3 with a $1,000 deductible, replacement cost on the dwelling, and actual cash value on personal property. Her insurer estimates $180,000 to rebuild the house and $25,000 for her 10-year-old furniture, which would cost $60,000 new. Kenji's rental agreement with Mia contains a mutual waiver of subrogation, but Lani signed nothing. Mia quitclaimed her interest in the duplex to her ex-husband two years ago, yet he is still a named insured on her rental dwelling policy. Both insurers have hired counsel.
1. Lani insists she is owed $240,000 - $180,000 to rebuild plus $60,000 for new furniture. Compute what her insurer actually owes and explain each adjustment.

Payment: $204,000 ($180,000 + $25,000 − $1,000).
Dwelling - $180,000. Replacement cost applies, but it is conditional: the insured must actually repair or replace, and most forms impose a minimum-limit condition (commonly 80% of replacement cost) before full RC settlement is available. The estimate is within the limit, so $180,000 stands.
Contents - $25,000, not $60,000. The policy is ACV on personal property. ACV = replacement cost minus depreciation; the $35,000 difference for 10 years of use is not recoverable. Only a replacement-cost contents endorsement would close that gap.
One deductible per occurrence. The fire is a single occurrence, so the $1,000 applies once to the combined loss, not separately to building and contents.
The indemnity principle is the through-line: Lani is restored to roughly her pre-loss position, not put in a better one. Her demand of $240,000 would over-indemnify her by $36,000.
2. Lani's insurer pays the claim and sues Kenji. Kenji's attorney argues the waiver of subrogation in the rental agreement bars the suit. Evaluate the argument.

The argument fails on privity. A waiver of subrogation is a contract term binding only the parties to it - Mia and Kenji. Subrogation is derivative: Lani's insurer steps into Lani's shoes and takes only the rights Lani had. Lani never waived anything against Kenji, so her insurer acquired an unwaived negligence claim.
The waiver would have mattered if Kenji had been an insured under Mia's policy (for example, by endorsement as an additional insured on the rental dwelling form). He is a tenant, not an insured, so Mia's insurer owes him no defense and no waiver protection.
Limits worth flagging to the adjuster:
- Recovery cannot exceed what the insurer paid ($204,000), and Lani's $1,000 deductible is normally reimbursed to her first out of any recovery.
- Kenji can still litigate comparative fault; a negligence finding reduced by his own or others' fault shrinks the subrogation recovery, not Lani's settlement.
Lesson: waivers protect only the contracting party, and only if that party is also an insured on the paying policy.
3. Mia's ex-husband, still a named insured, files a claim for his share of the duplex. Analyze whether he recovers, and whether his status damages Mia's claim.
Read the worked answer
He recovers nothing for the building. Insurable interest is tested at the time of loss. The quitclaim deed two years ago transferred his ownership interest to Mia, so at the moment of the fire he had no financial interest that would be impaired by the loss. A named insured without insurable interest cannot collect for damage to property he does not own - paying him would violate indemnity and invite a windfall.
Mia's claim is not impaired. Property coverage is severable as to the interests of insureds. The absence of interest in one named insured does not void the policy for the others; Mia's ownership interest supports full payment to her. The mortgagee's interest is likewise unaffected and is paid per the mortgage clause regardless of the dispute between the named insureds.
The practical wrinkle is the claim check: payees include both named insureds and the mortgagee. The insurer should not release funds to the ex-husband without evidence of his interest, and may need an interpleader or a signed release from him to clear the draft. Coverage for defense of a liability claim is a separate question controlled by whether he qualifies as an insured, not by insurable interest in the building.
