Because it is a bank of repute.
The State child support agency does this.
If you owe money to the bank they are entitled to withdraw it from any monies deposited into your account.

The only way to stop child support enforcement from attaching your bank accounts is to pay what you owe in arrears and continue to pay what you owe on time.
Only if there are arrears on the child support case and you can convince Child Support Services to garnish the settlement or the bank account of the other parent.

No. But you should take care not to have any joint bank accounts with your husband. If he falls behind in his child support obligations the court could freeze his bank accounts.
(Possibly) those funds that belong to a joint owner of the account and not to the child support obligor.
You need to make your inquiry at your particular child support enforcement office. There is no universal answer
I suggest you contact your State's child support agency about this.
