Chapter I Building Unit Ownership (Articles 63 to 64-4)

The law as Act Partially Amending the Act on Building Unit Ownership, etc. to Facilitate Management and Revitalization of Aging Condominiums, etc. (Act No. 47 of 2025) leaves it, with the words it changes marked.

The main text is read a page at a time: a chapter to a page, and a long chapter in runs of articles. The whole main text, and the supplementary provisions and appended tables this amendment changes. Those it leaves untouched are on the page for the text in force.

Article 63第六十三条

Requesting the Sale of Unit Ownership(区分所有権等の売渡し請求等)
Article 63, paragraph (1)

If a resolution to reconstruct has been adopted, the person who convened the meeting must, without delay, demand in writing that the unit owners who were not in favor of the resolution to reconstruct (including their successors) answer whether or not they will participate in the reconstruction in accordance with the content of the resolution to reconstruct.

建替え決議があつたときは、集会を招集した者は、遅滞なく、建替え決議に賛成しなかつた区分所有者(その承継人を含む。)に対し、建替え決議の内容により建替えに参加するか否かを回答すべき旨を書面で催告しなければならない。

Article 63, paragraph (2)

Pursuant to the provisions of Ministry of Justice Order and with the consent of the unit owners provided for in the preceding paragraph, in lieu of a demand in writing under the provisions of the preceding paragraph, the person who convened the meeting may use electronic or magnetic means to make a demand that those who were not in favor of the resolution to reconstruct answer whether or not they will participate in the reconstruction in accordance with the content of the resolution to reconstruct. In such a case, the person who convened the meeting is deemed to have made the demand in writing.

集会を招集した者は、前項の規定による書面による催告に代えて、法務省令で定めるところにより、同項に規定する区分所有者の承諾を得て、電磁的方法により建替え決議の内容により建替えに参加するか否かを回答すべき旨を催告することができる。この場合において、当該集会を招集した者は、当該書面による催告をしたものとみなす。

Article 63, paragraph (3)

A unit owner provided for in paragraph (1) must give their answers within two months from the day on which they received the demand under that paragraph.

第一項に規定する区分所有者は、同項の規定による催告を受けた日から二月以内に回答しなければならない。

Article 63, paragraph (4)

A unit owner provided for in paragraph (1) who has failed to give an answer within the period under the preceding paragraph is deemed to have answered that they will not participate in the reconstruction.

前項の期間内に回答しなかつた第一項に規定する区分所有者は、建替えに参加しない旨を回答したものとみなす。

Article 63, paragraph (5)

After the period under paragraph (3) has expired, each unit owner who was in favor of the resolution to reconstruct or each unit owner who has answered that they will participate in the reconstruction in accordance with the content of the resolution to reconstruct (including the successors of those unit owners), or any person who has been designated as the person who may purchase the unit ownership or the rights to use the grounds with the unanimous consent of the unit owners (hereinafter referred to as the "designated purchaser") may demand that the unit owners who have answered that they will not participate in the reconstruction (including their successors) sell and transfer their unit ownership and the rights to use the grounds at their market value, within two months from the day that the period under paragraph (3) expires. The same applies to the rights to use the grounds that are held by a person who has acquired only the rights to use the grounds from a unit owner who has answered that they will not participate in the reconstruction after the adoption of the resolution to reconstruct (including that person's successor).

第三項の期間が経過したときは、建替え決議に賛成した各区分所有者若しくは建替え決議の内容により建替えに参加する旨を回答した各区分所有者(これらの者の承継人を含む。)又はこれらの者の全員の合意により区分所有権及び敷地利用権を買い受けることができる者として指定された者(以下「買受指定者」という。)は、同項の期間の満了の日から二月以内に、建替えに参加しない旨を回答した区分所有者(その承継人を含む。)に対し、区分所有権及び敷地利用権を時価で売り渡すべきことを請求することができる。建替え決議があつた後にこの区分所有者から敷地利用権のみを取得した者(その承継人を含む。)の敷地利用権についても、同様とする。

Article 63, paragraph (6)

If a request under the preceding paragraph has been made, and if a unit owner who has answered that they will not participate in the reconstruction is likely to suffer extreme difficulty in their daily life as a result of vacating the building and there are obvious grounds for finding that the evacuation will not have a significant influence on the implementation of the resolution to reconstruct, the court, at the request of that person, may grant the person a reasonable period to vacate the building, within the scope of one year from the day of the payment or provision of the purchase money.

前項の規定による請求があつた場合において、建替えに参加しない旨を回答した区分所有者が建物の明渡しによりその生活上著しい困難を生ずるおそれがあり、かつ、建替え決議の遂行に甚だしい影響を及ぼさないものと認めるべき顕著な事由があるときは、裁判所は、その者の請求により、代金の支払又は提供の日から一年を超えない範囲内において、建物の明渡しにつき相当の期限を許与することができる。

Article 63, paragraph (7)

If demolition work on the building has not commenced within two years after the day a resolution to reconstruct was adopted, within six months from the day of the expiration of that period, a person who has sold their unit ownership or rights to use the grounds pursuant to the provisions of paragraph (5) may demand that the person who holds the unit ownership or the rights to use the grounds at the time in question sell and transfer those rights, by offering the current holder money equivalent to the purchase money paid to them by the purchaser; provided, however, that this does not apply if there are legitimate grounds for not commencing the demolition work on the building.

建替え決議の日から二年以内に建物の取壊しの工事に着手しない場合には、第五項の規定により区分所有権又は敷地利用権を売り渡した者は、この期間の満了の日から六月以内に、買主が支払つた代金に相当する金銭をその区分所有権又は敷地利用権を現在有する者に提供して、これらの権利を売り渡すべきことを請求することができる。ただし、建物の取壊しの工事に着手しなかつたことにつき正当な理由があるときは、この限りでない。

Article 63, paragraph (8)

In the case prescribed in the proviso to the preceding paragraph, the provisions of the main clause of the preceding paragraph apply mutatis mutandis if demolition work on the building has not commenced within six months from the day on which the reasons preventing the commencement of the demolition work have ceased to exist. In such a case, the phrase "within six months from the day of the expiration of that period" in the main clause of the preceding paragraph is deemed to be replaced with "by the time six months have elapsed from the day on which the person who sold the unit ownership or the rights to use the grounds became aware that the reasons preventing the commencement of demolition work on the building have ceased to exist, or two years from the day on which those reasons ceased to exist, whichever comes earlier".

前項本文の規定は、同項ただし書に規定する場合において、建物の取壊しの工事の着手を妨げる理由がなくなつた日から六月以内にその着手をしないときに準用する。この場合において、同項本文中「この期間の満了の日から六月以内に」とあるのは、「建物の取壊しの工事の着手を妨げる理由がなくなつたことを知つた日から六月又はその理由がなくなつた日から二年のいずれか早い時期までに」と読み替えるものとする。
