If a lessee of a building used as residences dies without an heir, and there is a person who is in a de facto husband and wife relationship or foster parent and child relationship with the lessee of a building without submitting a notice of marriage or adoption at that time who lived together with the lessee of the building, that person that lived together with the lessee succeeds to the rights and obligations of the lessee of the building; provided, however, that this does not apply if the person manifest a contrary intention to the lessor of the building within one month after learning that the lessee of the building has died without an heir.
居住の用に供する建物の賃借人が相続人なしに死亡した場合において、その当時婚姻又は縁組の届出をしていないが、建物の賃借人と事実上夫婦又は養親子と同様の関係にあった同居者があるときは、その同居者は、建物の賃借人の権利義務を承継する。ただし、相続人なしに死亡したことを知った後一月以内に建物の賃貸人に反対の意思を表示したときは、この限りでない。
In the case referred to in the main clause of the preceding paragraph, the claims or obligations arising out of the lease relationship of a building belong to the person who has succeeded to the rights and obligations of the lessee of the building pursuant to the provisions of that paragraph.
