Warranty - Where an Insured undertakes that a particular thing will or will not be done, that a condition will be fulfilled or affirms or negates a particular state of facts.
Weekly benefits (under personal accident) - They are paid for the period of temporary total disablement following an injury.
Wear and tear exclusion - A common heading for an "all risks" exclusion relating to a group of events that do not represent risk at all. Property will become worn out and torn; it will rust, settle, become rotted, infested, marred, scratched, etc. It is easy to distinguish however between the marring that occurs over time (excluded) and marring that occurs when a concrete block is dropped onto a fine wooden table.
