Article 31Adjustment of Payment of the Allowance

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.
