Article 104Participation in Proceedings When Two or More Persons Have the Obligation of Performing the Entire Proceedings
第百四条（全部の履行をする義務を負う者が数人ある場合等の手続参加）
When several persons have the obligation to perform the entire proceedings respectively, if an order commencing bankruptcy proceedings is made against all or some or one of them, their creditor may participate in the bankruptcy proceedings against each person with regard to the whole amount of the claim that they hold at the time of commencement of bankruptcy proceedings.
数人が各自全部の履行をする義務を負う場合において、その全員又はそのうちの数人若しくは一人について破産手続開始の決定があったときは、債権者は、破産手続開始の時において有する債権の全額についてそれぞれの破産手続に参加することができる。
In the case referred to in the preceding paragraph, even if other persons who have the obligation to perform the entire proceedings have paid the creditor or conducted any other act with the creditor to cause their debt to be extinguished (referred to below as "payment, etc." in this Article) after the commencement of bankruptcy proceedings, except if the whole amount of the claim is extinguished, the creditor may exercise their right for the whole amount of the claim that they hold at the time of the commencement of bankruptcy proceedings.
前項の場合において、他の全部の履行をする義務を負う者が破産手続開始後に債権者に対して弁済その他の債務を消滅させる行為（以下この条において「弁済等」という。）をしたときであっても、その債権の全額が消滅した場合を除き、その債権者は、破産手続開始の時において有する債権の全額についてその権利を行使することができる。
In the case prescribed in paragraph (1), a person that has a right to receive reimbursement to be exercised against the bankrupt in the future may participate in the bankruptcy proceedings with regard to the whole amount of reimbursement; provided, however, that this does not apply when a creditor has participated in the bankruptcy proceedings regarding the claim that they hold at the time of commencement of bankruptcy proceedings.
When a creditor participates in the bankruptcy proceedings pursuant to the provisions of paragraph (1), if a person that has a right to receive reimbursement to be exercised against the bankrupt in the future has made payment, etc. to the creditor after the commencement of bankruptcy proceedings, the person that has a right to receive reimbursement may exercise the creditor's right as a bankruptcy creditor to the extent of the right to receive reimbursement only when the whole amount of the creditor's claim is extinguished.
The provisions of paragraph (2) apply mutatis mutandis when a third party that provided their property as security in order to secure the bankrupt's debt (referred to below as a "third party collateral provider" in this paragraph) has made payment, etc. to the creditor after the commencement of bankruptcy proceedings, and the provisions of the preceding two paragraphs apply mutatis mutandis to a third party collateral provider that has the right to obtain against the bankrupt in the future.
