<![CDATA[A sales cooperation agreement between a principal and a distributor is the backbone of goods distribution in modern business practice, yet it is not specifically regulated as a nominate contract in the Indonesian Civil Code, raising questions concerning the certainty of its regulation and the legal protection of the parties in the event of imbalanced clauses, breach of contract, or unilateral termination. This study aims to examine the legal regulation of sales cooperation agreements between principals and distributors from a business law perspective and its conformity with the principles of contract law in Indonesia, and to describe the forms of legal protection and dispute settlement available to the parties. This research is a normative legal study of a descriptive-analytical nature, employing statutory and conceptual approaches, using secondary data consisting of primary, secondary, and tertiary legal materials collected through library research and analyzed qualitatively using deductive reasoning. The results show, first, that the sales cooperation agreement constitutes an innominate contract which is valid under the open system of Book III of the Civil Code and receives sectoral regulation through Law Number 7 of 2014, Government Regulation Number 29 of 2021, and Minister of Trade Regulation Number 24 of 2021, and that it normatively conforms with the principles of contract law, although such conformity is formal in nature owing to the unequal bargaining positions of the parties. Second, legal protection is available preventively through the requirements of written agreements, registration of the distribution engagement, and balanced contract drafting, and repressively through actions for breach of contract, tort claims against unilateral termination in accordance with the settled jurisprudence of the Supreme Court, and the annulment of unlawful clauses, while disputes may be settled through litigation or through alternative dispute resolution and arbitration under Law Number 30 of 1999.]]>
