(c) This section does not prohibit the district attorney or the local child support agency from bringing an action or initiating process to enforce or punish the failure to obey an order for spousal support under any law that empowers the district attorney or the local child support agency to bring an action or initiate a process, whether or not there has been a referral by the court pursuant to this chapter.

(d) Any notice from the district attorney or the local child support agency requesting a meeting with the support obligor for any purpose authorized under this part shall contain a statement advising the support obligor of the obligor's right to have an attorney present at the meeting.
