Article 18Amending an Action; Counterclaims

第十八条(訴えの変更及び反訴)

Notwithstanding the provisions of Article 143, paragraphs (1) and (4) of the Code of Civil Procedure and of Article 146, paragraph (1) and Article 300 of that Code, in personal status litigation proceedings, a plaintiff may amend a claim or cause of action, and a defendant may file a counterclaim, until the conclusion of the oral arguments in the first or second instance.

人事訴訟に関する手続においては、民事訴訟法第百四十三条第一項及び第四項、第百四十六条第一項並びに第三百条の規定にかかわらず、第一審又は控訴審の口頭弁論の終結に至るまで、原告は、請求又は請求の原因を変更することができ、被告は、反訴を提起することができる。

If the Japanese courts would have no jurisdiction over the claim relating to personal status litigation resulting from the amendment of a claim, the plaintiff may amend a claim pursuant to the provisions of the preceding paragraph only if in the resulting claim the plaintiff seeks to change the status of the same familial relationship as the one involved in the pre-amendment claim or seeks a declaratory judgment as to whether that familial relationship exists.

日本の裁判所が請求の変更による変更後の人事訴訟に係る請求について管轄権を有しない場合には、原告は、変更後の人事訴訟に係る請求が変更前の人事訴訟に係る請求と同一の身分関係についての形成又は存否の確認を目的とするときに限り、前項の規定により、請求を変更することができる。

If the Japanese courts have no jurisdiction over a claim as set forth in one of the following items that is the subject of a counterclaim, the defendant may file a counterclaim under the provisions of paragraph (1) only in the case specified in :

日本の裁判所が反訴の目的である次の各号に掲げる請求について管轄権を有しない場合には、被告は、それぞれ当該各号に定める場合に限り、第一項の規定による反訴を提起することができる。

a claim relating to personal status litigation: if the subject of the counterclaim is a claim through which the defendant seeks to change the status of the same familial relationship as the one involved in the claim relating to personal status litigation that is the subject of the principal action or a claim through which the defendant seeks a declaratory judgment as to whether that familial relationship exists; or

人事訴訟に係る請求 本訴の目的である人事訴訟に係る請求と同一の身分関係についての形成又は存否の確認を目的とする請求を目的とする場合

a claim for damages arising from facts constituting a cause of action relating to personal status litigation: if the relevant personal status litigation is already pending before a Japanese court.
