You dont need a marriage certificate to be legally married. If you went through the ceremony and your ex partner admits it, then for all intents and purposes you were married. You should go to the county where you were married in and look for the record. You will most likely need to divorce form the first before you get remarried, otherwise you will be entering a bigamous marriage.
For self represented individuals you can consult with the family law facilitator self help center at your local court house.
As always please consult a local attorney prior to taking legal action. Good luck. Also please check out my Santa Clara County Family Lawyer blog.
