For this reason, the general objective will be to analyze how the limitation to the creditor's right to contractual termination is configured, under the terms of the Civil Code of 2002, in view of the application of the substantial performance. The methodology used was a literature review and document analysis. So in analise to jurisprudence and doctrine, the function of substantial performance became evident as a mechanism to avoid excesses in the exercise of the prerogative of the creditor to claim breach of contract, limiting the resolution to essential default.Acesso AbertoTeoria do adimplemento substancialResolução contratualInadimplementoÔnus excessivoSubstantial performanceBreach of contractDefaultBurdenTrabalho de Conclusão de CursoCiências Sociais AplicadasDireito
