Summarize this article in one sentence.
Some courts have a family law facilitator or a self-help center that can help review the required forms and ensure you have properly filled them out.  After ensuring your forms are correctly filled out, make several copies of each form so you will have enough copies to file with the court, send to other parties, and keep for your own records. You will have to pay a fee to file with your forms in order to begin the proceedings. The court website has information on how much your fee will be.  To determine if you qualify for a fee waiver, visit the court’s website. You must be a resident of California to file an annulment in California, however, unlike a divorce, there is no minimum residency requirement to file an annulment. You should file your annulment in the county in which you reside. Visit the clerk’s office in person, pay the filing fee, and file your completed forms with the court’s clerk's office.  In some cases, and depending on the local rules of your county court, you may be able to file the case via mail. However, be aware that this may cause a significant delay in the filing of the case. To determine whether your local court will allow for filing via mail, what to include in your mailing to the court, and where to direct the mailing to, contact the court clerk's office.

Summary:
Review and copy your forms. Calculate the filing fee. Find the correct court. File the forms with the clerk.
