File amended petition (if petitioner). If you were the spouse who filed the original petition for legal separation, you can amend it to divorce by refiling the same form (FL-100) filled out to reflect the terms of your legal separation with the boxes checked for "dissolution" and "amended."

File amended response (if respondent). If you were not the spouse who filed the original petition, but you filed a response to the petition, you can amend to divorce by filing a new response form (FL-120) filled out to reflect the terms of the legal separation and marked for dissolution and amended.

Serve process. Whether you are the petitioner or respondent, you must serve a copy of the amended form on your other spouse in a lawful manner. This usually means either hiring the sheriff or a professional process server, but you can also have a friend over 18 hand-deliver the form and file the verification of service form with the court.


  • If the terms of your legal separation are already established and reflected in a court order, you should file form FL-820 with the court at the time of filing the amendment and include it in the service of process. If not, the potentially lengthy process of stipulating the terms of the separation will continue, but divorce will be the ultimate legal outcome.
