You can have the court filing fees waived by filing a court form called In Forma Pauperis.  This is the  form to file with the court when you can't afford the filing fees.  The form does require disclosure of your financial information.As for the filing fees to file a demurrer or motion to dismiss, the court clerk can tell you the current amount of these fees.  Again, if you file the In Forma Pauperis court form, you can waive those filing fees.
