This thesis explores the topic of obligations involving multiple debtors and creditors, with a particular focus on divisible and indivisible obligations and the role of joint and several obligations within the legal framework. The introduction outlines the duty to fulfill obligations, followed by an analysis of divisible obligations, which include the division of debt and claims among multiple debtors and creditors. Special attention is given to dualistic and pluralistic obligations, as well as the complexity of joint and several obligations, which are crucial for understanding legal solidarity among debtors. The thesis also examines the sources of joint and several obligations and the mechanisms for their termination, including set-off, debt forgiveness, novation, and settlement. Additionally, the concepts of creditor and debtor delay, as well as the legal consequences of debt acknowledgment, are addressed. The concluding section discusses the suspension and interruption of prescription periods and the rights of the performer to compensation, thereby providing a comprehensive overview of the legal framework governing obligations involving multiple debtors and creditors.
