When Treasury's Bureau of the Fiscal Service processes a tax refund, it matches the noncustodial parent's debt and intercepts part or all of the tax refund, depending on how much is owed. Working through OCSE, the offset payment is then sent to the state child support agency to pay toward the past-due support.

Will the 3rd stimulus be intercepted by child support?

With the third check, if you're past due on child support, you can still receive your full stimulus payment. It won't be redirected to cover late support payments. This holds true for any past-due federal or state debts: Your third payment is not subject to reduction or offset.

Will the second stimulus be intercepted for back child support?

By law, your second and third stimulus checks cannot be reduced to pay your or your spouse's past due child support. Your second and third stimulus checks will not be offset for any Federal or state debts. However, only your second stimulus check is protected from private debtors and creditors.
