For example, a shopper buying a gift for someone else can write on the receipt that the recipient should have rights under the contract of sale, and get the retailer to sign it. If the product then turns out to be defective, the recipient can sue in their own right. Where a contract does not state whether it should give rights to third parties, a court will look at whether there is other evidence that suggests the relevant term purports to confer a benefit on a third party.
