      **第一項**  債務者の交替による更改は、債権者と更改後に債務者となる者との契約によってすることができる。この場合において、更改は、債権者が更改前の債務者に対してその契約をした旨を通知した時に、その効力を生ずる。

      A novation by substitution of obligor may be effected by a contract concluded between the obligee and a person that becomes the obligor after the novation. In such a case, the novation becomes effective when the obligee notifies the obligor before the novation of the conclusion of the contract.
