Warranty Terms in Plain Words

A warranty is a promise with edges. Knowing where the edges are tells you how much comfort it really gives.

What the word means

In law, a warranty is an expressed or implied promise or assurance of some kind, and its meaning varies across legal subjects. For a purchase, it is usually the seller's or maker's promise about the condition or performance of what you bought.

Express and implied

An express warranty is stated, in writing or in words. An implied warranty, in common law jurisdictions, is a set of assurances presumed to be made in a sale because of the circumstances, whether or not the seller promised them. What is implied, and for how long, differs from place to place, so treat the printed warranty as one layer and your local law as another.

Read these parts first

• Who stands behind it: the seller, the manufacturer or a third party.
• What is covered: defects only, or also wear, accidental damage and parts such as batteries.
• What voids it: repairs by unapproved people, use outside the stated purpose, missing registration or missing proof of purchase.
• What the remedy is: repair, replacement or refund, and who pays for shipping.
• What the duration is: and when it starts counting.

Extended plans are a separate product

A paid extension is a purchase in its own right. Treat it like any other: what does it add beyond what you already have, what does it exclude, and who actually performs the repair?
