If goods are sent to a consumer without a contract asking for them, the "recipient may [...] use, deal with, or dispose of the goods as if they were an unconditional gift to him"[12] and "[t]he rights of the sender to the goods are extinguished".[13] This is intended to prevent companies purporting to demand payment for goods a consumer receives unexpectedly. This provision amends the Unsolicited Goods Act 1971, which defines goods only as unsolicited goods if they have been deliberately sent to the recipient with the intention of them being used. Goods sent or delivered by mistake are not unsolicited goods, and remain the property of the sender.
