Legal Protection for Consumers Who Buy and Sell Used Goods on Facebook

High consumer interest in purchasing used goods through platforms like Facebook, where the buyer is unknown, is evident. These goods are typically sourced from their original locations, which sometimes leads to consumer losses. The purpose of this research is to acquire knowledge and understanding of the legal protections available to consumers who purchase used goods on the Facebook platform. The research methods employed are normative, utilizing a regulatory legislation approach described as descriptive. This research focuses on analyzing and solving problems that occurred during the study. Consumer rights in these transactions are regulated under Article 4 of the Consumer Protection Act (UUPK), reinforced by the obligations of entrepreneurs in Article 7 of the UUPK. The sale of used goods is also addressed in Chapter 8, Paragraph 2 of the UUPK, which stipulates that entrepreneurs must not sell used goods without providing clear information. To prevent fraud involving stolen goods, consumers must adhere to Article 28 (1) of the ITE Act. Dispute resolution between consumers can be conducted through both litigation and non-litigation methods.
