One of the issues that arise from the contractual relationship is non-performance of the contract because there are always some risks that parties do not perform their contractual duties. This thesis includes two different types of non-performance of the contract from a comparative perspective: (i) strict liability and (ii) fault principle that dominant principles apply in most of the jurisdictions. Therefore, this paper will discuss how these principles apply to the common law and civil law system. The first chapter of this thesis will be a brief introduction part. The second chapter of this thesis will introduce different types of non-performance of the contract, such as the impossibility of contract, delay in contract, and incomplete performance. The third chapter will discuss fault principles as set forth in German and French law. The fourth chapter will start with the English and American law on strict liability for breach of contract and comparison of these principles. Here, I desire to seek the reason why these jurisdictions apply strict liability for breach of contract, how it is applied, and what situations are excluded. Further chapters will discuss the non-performance of the contract regulated in International law and will consider Mongolian contract law.
