Glossary

Plain-language definitions of the terms that decide whether a claim gets paid. Understand these eleven and you can read any contract in this category and know what you are actually buying.

Vehicle service contract (VSC)
What you actually bought. An agreement for a separately stated consideration to repair or replace covered parts. Legally distinct from a warranty, regulated by the state, not by any federal agency for solvency or claims practice.
Obligor / provider
The entity legally required to perform under your contract. Frequently not the brand that sold it to you. Write this name down at purchase.
Administrator
The company that adjudicates your claim — approves, denies, and authorises the shop. Often a third party. This is who you will actually be arguing with.
Reimbursement insurance policy
An insurer's policy issued to the provider, agreeing to discharge the provider's obligations — including refunding unearned fees — if the provider fails. This is your backstop. Where one exists, the contract must generally state that if the provider fails to pay a claim within sixty days of proof of loss, you may claim directly against the insurer — see the escalation guide.
Exclusionary vs. named-component
An exclusionary contract lists what is not covered; everything else is in. A named-component (or "stated component") contract lists what is covered; anything absent from the list is out. Exclusionary is materially better and is usually what the top tier means.
Mechanical breakdown vs. wear and tear
The most consequential ambiguity in the product. Narrow contracts cover only a sudden breakdown and exclude normal wear. Since most failures on a high-mileage vehicle are the end state of gradual wear, this definition can be pointed at a large share of claims.
Betterment / depreciation clause
Reduces the payout on the theory that a new part in an old car leaves you better off than before. Effect: you pay a percentage of a covered repair, on top of your deductible. Ask whether one applies before you buy — it is rarely volunteered.
Teardown authorisation
Disassembly required to diagnose a failure. If the claim is denied afterwards, you may owe the teardown and the reassembly, with the car still not running. Ask who pays on a denial, and get the answer in writing.
Waiting period
Typically 30 days and 1,000 miles before anything is payable. Combined with the pre-existing condition exclusion, this is how most early claims are denied.
Free look
The window for a full refund with no claim filed. Ranges from 9 days (Washington) to 60 days (Florida, and some California contracts). After it closes you get pro rata, usually minus an administrative fee.
Aggregate limit
A cap on total lifetime payout under the contract, separate from any per-claim cap. Watch for caps tied to the vehicle's actual cash value — those shrink every year you own the car, exactly as your risk of a major repair rises.

Every provider record on the ratings page lists these terms where the company discloses them — obligor, administrator, underwriter, deductible, free-look window, transferability and claim caps — so you can compare them side by side before you talk to anyone.
