If you have atty, ask your atty as he/she is most familiar with the case and the judge. generally, you can bring him back for addl monetary sanctions, evidentiary sanctions, issue sanctions, and possibly striking his response to your petition or motion. He could be brought in on contempt, and have jail dangled over his head. Unfortunately, even if you get money sanctions and atty fees, or whatever else you are asking for, if he doesnt have assets or money that is "findable" to collect from, you are still in a bind. If this involves failure to pay child support, the court can take away his license to drive and professional licensing.
i agree with Attorney Kopelson's answer, failing to comply with a court order is very serious and can lead to a variety of consequences, including monetary and case sanctions.

I don't believe in unnecessarily enabling self-representation esp. when I'm doing so for free. I suggest that you have the L.A. County Department of Child Support Services take over enforcement of your child (and any spousal) support rights for free and consult for free with the Family Law Facilitator's Office otherwise. Generally, self-employed spouses create more headaches than do employed ones; those who work for cash without adequate records and/or are marginal earners create more problems.
