How to determine the territorial jurisdiction of contract dispute cases

In principle, contract disputes shall be under the jurisdiction of the court where the defendant is located or where the contract is performed, but both parties may also choose in writing.

The law provides that:

Article 23 of the Civil Procedure Law: A lawsuit arising from a contract dispute shall be under the jurisdiction of the people's court of the defendant's domicile or the place where the contract is performed.

Article 34. The parties to a dispute over a contract or other property rights and interests may, through written agreement, choose a people's court in a place that has a real relationship with the dispute, such as the defendant's domicile, the place where the contract is performed, the place where the contract is signed, the plaintiff's domicile and the place where the subject matter is located, but it shall not violate the provisions of this Law on hierarchical jurisdiction and exclusive jurisdiction.
