A loan agreement has been concluded over the phone between a trader and a consumer. Article 20 paragraph 2 of the Act on Consumer Rights states that if the entrepreneur proposes to the consumer to enter into a contract over the phone, he must confirm the content of the proposed contract recorded on paper or another durable medium. The consumer's statement regarding the conclusion of the contract is effective if it has been recorded on paper or another durable medium after receiving the confirmation from the trader. Therefore, it should be pointed out that during the telephone conversation or after it, the entrepreneur must contact the consumer and provide the content of the proposed agreement on a durable medium. Of course, the law (sentence 1 of Article 20 paragraph 2 of the Act) does not require the delivery of the content of the contract in paper form. For example, it is possible to do this by e-mail. Nevertheless, the consumer must know what he agrees to (know the content of the contract) before making a declaration of contract by telephone, which should be recorded on paper or another durable medium.
