<sup>art-429 · https://japanlaw.org/en/civil-code/art-429 · https://japanlaw.org/l/129AC0000000089/art-429</sup>

      **第一項**  不可分債権者の一人と債務者との間に更改又は免除があった場合においても、他の不可分債権者は、債務の全部の履行を請求することができる。この場合においては、その一人の不可分債権者がその権利を失わなければ分与されるべき利益を債務者に償還しなければならない。
      <sup>art-429/par-1 · https://japanlaw.org/en/civil-code/art-429/par-1 · https://japanlaw.org/l/129AC0000000089/art-429/par-1</sup>
      Even if there is a novation or release between one of the obligees of an indivisible claim and the obligor, other obligees may request the obligor to perform the obligation in whole. In such a case, the benefit which should have been allocated to that one obligee if that obligee did not lose the relevant right must be reimbursed to the obligor.
