A boa-fé objetiva como fundamento normativo no Código Civil e no Código de Defesa do Consumidor

Abstract

This paper explores the intersection between civil law and consumer law, analyzing contractual principles to emphasize the importance of good faith in consumer relations. In addition, it highlights the connection of this principle with the general duty of information. The objective is to contribute to a deeper understanding of the application of good faith in contractual relationships between consumers and suppliers. In the Civil Code, it imposes a standard of behavior based on loyalty, transparency and cooperation between the parties, ensuring balance in contracts. In the CDC, objective good faith reinforces consumer protection, requiring suppliers to act ethically and provide adequate information about products and services. In this way, the principle guides the interpretation and execution of contracts, preventing abuse and ensuring justice in legal relationships.
