Which type of warranty involves a promise to fulfill a specific obligation?

The type of warranty that involves a promise to fulfill a specific obligation is the promissory warranty. This warranty explicitly commits the warrantor to uphold certain conditions or actions. A promissory warranty typically arises in contracts, where one party makes a promise to perform certain tasks or adhere to specific standards, providing assurance to the other party that they can expect certain outcomes as a result of that promise.

In contrast, an affirmative warranty is more about expressing truth concerning specific facts or conditions at the time of the agreement, rather than promising to take action. An express warranty involves explicit statements or guarantees made by the seller about the quality or nature of a product, and while it provides assurance, it doesn’t necessarily involve a promise of future action in the same way a promissory warranty does. An implied warranty originates from law and is automatically inferred in certain transactions, regardless of explicit agreements, focusing on the quality and fitness of goods sold rather than specific promises made.
