In any case where there is a conviction under either Section 270 or 270a and there is an order granting probation which includes an order for support, the court may:

1. (a) Issue an execution on the order for the support payments that accrue during the time the probation order is in effect, in the same manner as on a judgment in a civil action for support payments. This remedy shall apply only when there is no existing civil order of this state or a foreign court order that has been reduced to a judgment of this state for support of the same person or persons included in the probation support order.

2. (b) Issue an earnings assignment order for support pursuant to Chapter 8 (commencing with Section 5200) of Part 5 of Division 9 of the Family Code as a condition of probation. This remedy shall apply only when there is no existing civil order for support of the same person or persons included in the probation support order upon which an assignment order has been entered pursuant to Chapter 8 (commencing with Section 5200) of Part 5 of Division 9 of the Family Code or pursuant to former Chapter 5 (commencing with Section 4390) of Title 1.5 of Part 5 of Division 4 of the Civil Code.

   These remedies are in addition to any other remedies available to the court.
