Legal Question in Family Law in California

You can try to get an enforcement order, called an "order to show cause," yourself. You should be able to get some general guidance and help from the family law self help centers of the Orange County courts: http://www.occourts.org/directory/family/self-help.html

You can also probably find an attorney who would take the matter on a limited retainer, since your ex is likely to have to pay your attorneys fees if you have to take him to court.
