The concise in the general rules of obligation in the Qatari law for Jaber Mahjoub Ali

The general theory of obligations is the backbone of all studies in the science of law; its rules govern most legal applications, especially in the field of civil law. The general theory of obligation contains two parts: the sources of obligation and the provisions of obligation; this publication's subject includes an explanation of the general provisions of obligation in Qatari civil law. It consists of four chapters; the first chapter deals with the effects of obligation; it begins with studying the forced specific performance of the obligation, then performance by way of compensation, ending with studying the guarantees of performance of the obligation; which are the indirect lawsuit, the lawsuit for invalidity of transactions, the lawsuit of fictitiousness, and the right of detention. As for the second chapter, it is dedicated to studying the characteristics of obligation; whether those related to the existence or enforceability of the obligation (condition and term), or the subject matter of the obligation (alternative obligation and substitute obligation), or related to the parties of the obligation (joint liability and indivisibility). The third chapter addresses the transfer of obligation, positively through assignment of the right, or negatively through assignment of debt. Finally, in the fourth chapter, we discussed the termination of the obligation, firstly through fulfillment, secondly through equivalent fulfillment, and thirdly through its termination without fulfillment.
