Repetition of warranties is the requirement that the seller’s warranties are given (or “repeated”) at completion as well as at signing. Where warranties are repeated at completion, the seller is liable if any warranty becomes inaccurate between signing and completion, even if it was accurate at signing.
In Australian sub-$20M deals, repetition is common where there is a meaningful gap between signing and completion. The seller will typically negotiate for a “bring-down” right, allowing them to update the disclosure letter against changes occurring between signing and completion, and either side may negotiate Material Adverse Effect protections to set a threshold below which the buyer cannot terminate.
