Much of the law relating to hire purchase is the general law of contracts. Some degree of regulation was introduced by the Hire Purchase Agreements Act of 1939. This lays down rules to protect purchasers where goods are repossessed by the seller. The object is to ensure that, because of the purchaser's inability to complete the transaction, the seller does not receive more than the price of the goods. The buyer cannot contract out of the Act, but it does not apply if the goods are voluntarily returned, albeit at the seller's persuasion.
