Abstract
One sphere regulated by International Civil Law is international business contracts which contain foreign elements. The existence of foreign elements in international business contracts is followed by the emergence of the freedom of the parties to determine choice of law and/or choice of forum. Without the inclusion of choice of law and/or choice of forum clauses, problems will arise about which country’s law applies and which forum is authorized to resolve international business contract disputes. One important thing related to choice of law and/or choice of forum in international business contracts is the limitations toward them. The research question is what are the limitations toward choice of law and/or choice of forum in international business contracts?. The research method used is juridical normative with statute approach and conceptual approach as problem approaches. The result of the research explicates in general, the limitations toward choice of law and/or choice of the forum in international business contracts are the limitations determined in Article 1339 of the Civil Code namely not contrary to propriety, customs, laws, and applicable legal system in every country. The parties need to understand the limitations toward choice of law and/or choice of forum clauses in international business contracts and implement them when making choice of law and/or choice of forum clauses so these clauses are not null and void.
