### 第三十一条（手当の支払の調整） — Adjustment of Payment of the Allowance
<sup>caption: machine translation, not official</sup>
<sup>art-31 · https://japanlaw.org/en/child-rearing-allowance-act/art-31 · https://japanlaw.org/l/336AC0000000238/art-31</sup>

**第一項**  手当を支給すべきでないにもかかわらず、手当の支給としての支払が行なわれたときは、その支払われた手当は、その後に支払うべき手当の内払とみなすことができる。第十二条第二項の規定によりすでに支給を受けた手当に相当する金額の全部又は一部を返還すべき場合におけるその返還すべき金額及び手当の額を減額して改定すべき事由が生じたにもかかわらず、その事由が生じた日の属する月の翌月以降の分として減額しない額の手当が支払われた場合における当該手当の当該減額すべきであつた部分についても、同様とする。
<sup>art-31/par-1 · https://japanlaw.org/en/child-rearing-allowance-act/art-31/par-1 · https://japanlaw.org/l/336AC0000000238/art-31/par-1</sup>
Where payment has been made as payment of the allowance even though the allowance should not have been paid, the allowance so paid may be deemed to be an advance payment of the allowance to be paid thereafter. The same applies to the amount to be returned where all or part of an amount equivalent to the allowance already received is to be returned under Article 12, paragraph (2), and to the portion that should have been reduced of an allowance, where grounds have arisen for revising the amount of the allowance by reducing it but an allowance of an unreduced amount has been paid for the months from the month following the month containing the day on which those grounds arose.
