Also, is there a draft child support agreement I can bring with me to the facilitator, so I could have some idea where I am at?
First, I must preface my answer by notifying you that I am not licensed to practice law in California where you are writing from.
With that being said, I was able to find a helpful website that concerns child support and custody disputes for residents living in California: http://www.courtinfo.ca.gov/selfhelp/family/custody/custforms.htm
Based upon the facts that you provided, it sounds like you may already have a facilitator to assist you through the legal mess of family law. While I understand that it may be expensive to consult with an attorney, it is also costly to arrive unprepared.
It is definitely in your best interest to review the self-help website I posted above for tips and explanation of the law and how it relates to your case.
Please understand that my opinions are based upon the limited facts that you provided to me. For a more in depth discussion of your legal rights in your jurisdiction, I urge you to contact a family law attorney immediately.
