①When an attestation of enforceability has been granted pursuant to the provisions of Article 27, an obligor who disputes that a fact to be proved by the obligee has occurred or objects to it being permissible to carry out judicial enforcement for or against a person other than the party indicated in the title of obligation may file an action opposing the granting of an attestation of enforceability to call for the court to disallow judicial enforcement based on the authenticated copy of the title of obligation bearing that attestation of enforceability.

②If there are several grounds for opposition, an obligor must allege those grounds at the same time.

③The provisions of paragraph (2) of the preceding Article apply mutatis mutandis to the action stated in paragraph (1).

①An obligor who disputes the existence or content of the claim under a title of obligation (excluding a title of obligation stated in Article 22, item (ii), or items (iii)-2 through (iv) which has yet to become final and binding; the same applies in this paragraph) may file an action to dispute the claim to call for the court to disallow judicial enforcement based on that title of obligation. The same applies for an obligor who disputes the establishment of a title of obligation not constituting a judicial decision.

②Grounds to dispute a final and binding judgment are limited to those that arise after the conclusion of oral arguments.

③The provisions of Article 33, paragraph (2) and paragraph (2) of the preceding Article apply mutatis mutandis to the action stated in paragraph (1).

①If an action opposing the granting of an attestation of enforceability or an action to dispute a claim has been filed, and if the circumstances that the person alleges for raising the opposition or dispute appear to be legally well-grounded and a prima facie showing is made on factual matters, the court in charge of the case, upon petition, may order a stay of enforcement until a judicial decision as referred to in paragraph (1) of the following Article is made in the final judgment, while either requiring or not requiring security to be provided, or, in addition to the order, may issue an order for judicial enforcement to continue while requiring security to be provided, or may issue an order voiding an enforcement measure that has already been taken while requiring security to be provided. If there are pressing circumstances, the presiding judge may also order these measures.

②The court may render a judicial decision on the petition referred to in the preceding paragraph without hearing oral arguments.

③If the grounds prescribed in paragraph (1) exist, if there are pressing circumstances, the enforcement court, upon petition, may order the measures prescribed in that paragraph, while specifying a period for submitting an authenticated copy or certificate of recorded information of a judicial decision under that paragraph. This judicial decision may also be made before the filing of an action opposing the granting of an attestation of enforceability or an action to dispute a claim.

④When the period specified pursuant to the provisions of the preceding paragraph has expired or when a judicial decision under paragraph (1) has been submitted to the enforcement court or court enforcement officer within the period, the judicial decision stated in the preceding paragraph ceases to be effective.

⑤No appeal may be entered against a judicial decision on the petition referred to in paragraph (1) or paragraph (3).

①In the final judgment on an action opposing the granting of an attestation of enforceability or an action to dispute a claim, the court in charge of the case may order the measures prescribed in paragraph (1) of the preceding Article or void, change, or approve a judicial decision under that paragraph that has already been made. The court must make a declaration of provisional enforcement for this judicial decision.

②No appeal may be entered against a judicial decision under the preceding paragraph.

①A third party who has ownership of the subject matter of judicial enforcement or any other right that obstructs assignment or delivery of the subject matter may file, against the obligee, a third-party action opposing enforcement to call for the court to disallow enforcement.

②The third party prescribed in the preceding paragraph may file an action against the obligor regarding the subject matter of judicial enforcement, in consolidation with the action referred to in that paragraph.

③The action referred to in paragraph (1) is under the jurisdiction of the enforcement court.

④The provisions of the preceding two Articles apply mutatis mutandis to a judicial decision to stay enforcement in connection with the action referred to in paragraph (1).

①Judicial enforcement must be stayed if any of the following documents has been submitted:

②A stay of judicial enforcement based on submission of a document stated in item (viii) of the preceding paragraph which contains a statement that an obligee received performance is limited to a period of four weeks.

③A stay of judicial enforcement based on submission of a document stated in paragraph (1), item (viii) which contains a statement that an obligee consented to granting a grace period for performance may be effected only twice, and the total period may not exceed six months.

①If a document stated in paragraph (1), items (i) through (vi) of the preceding Article has been submitted, the enforcement court or court enforcement officer must void even an enforcement measure that has already been taken.

②The provisions of Article 12 do not apply if the enforcement court or court enforcement officer voids an enforcement disposition pursuant to the provisions of the preceding paragraph.

①Judicial enforcement may be continued even if the obligor died after its commencement.

②In the cases of the preceding paragraph, if existence of an heir to the obligor or the whereabouts of this person is unknown, the enforcement court may, upon petition, appoint a special representative for the inherited property or heir.

③The provisions of Article 35, paragraphs (2) and (3) of the Code of Civil Procedure apply mutatis mutandis to the special representative referred to in the preceding paragraph.

①The cost of judicial enforcement that is necessary (referred to as "enforcement cost" below) is borne by the obligor.

②In judicial enforcement of claim for payment of money, the enforcement cost may be collected simultaneously in the course of the enforcement procedures without requiring a title of obligation.

③When a judicial decision revoking a title of obligation (excluding a notarial instrument authorizing enforcement) on which enforcement is based, or a judgment declaring invalidity of a settlement, acknowledgment, mediation or labor tribunal decision that a title of obligation concerns has become final and binding, the obligee must return, to the obligor, money equivalent to the enforcement cost that has been paid to the obligee.

④The enforcement cost to be borne by an obligor pursuant to the provisions of paragraph (1), other than that collected pursuant to the provisions of paragraph (2), and the amount of money to be returned by an obligee pursuant to the provisions of the preceding paragraph are established by a court clerk of the enforcement court, upon petition.

⑤A person may file an objection with the enforcement court to the court clerk's disposition concerning a petition under the preceding paragraph, within an inalterable period of one week from the day on which the person is notified of it.

⑥If the enforcement court finds there to be grounds to the filing of an objection to a court clerk's disposition under paragraph (4), and the enforcement cost and the amount of money to be returned prescribed in that paragraph are required to be established, the court must establish those amounts itself.

⑦An appeal against an enforcement decision may be filed against an order on the filing of an objection under the provisions of paragraph (5).

⑧A court clerk's disposition under paragraph (4) does not become effective until it becomes final and binding.

⑨The provisions of Article 74, paragraph (1) of the Code of Civil Procedure apply mutatis mutandis to a court clerk's disposition under paragraph (4). In this case, the provisions of paragraphs (5) and (7) and the preceding paragraph, and of Article 74, paragraph (3) of that Code, apply mutatis mutandis.
