required ¹

It is required by law that a husband $\$frac{\text{have to pay}}{\text{A}} the debts of his wife $\$frac{\text{until}}{\text{B}} formal notice is

given $\$frac{\text{that}}{\text{C}} he no longer has $\$frac{\text{to pay her.}}{\text{D}} (全国研考,93-69)

我认为选项 A(have to pay) 是错误的, 应改为 has to pay。
