First, reach out to your local parish priest or parish annulment advocate. (See below for a searchable list of parish annulment advocates.) This person will assist the Petitioner in completing the application for nullity that is submitted to the Tribunal and stays in close contact throughout the process.
Next, members of the Tribunal will contact the other party to the marriage (the Respondent), sending them a notification that the Petitioner has submitted a case, as well as a questionnaire. The cooperation of the Respondent varies from case to case. However, the Respondent’s participation is not essential, and a case can proceed without it after he or she has been notified.
During the course of the case, both the Petitioner and the Respondent will be able to review each other’s written testimony as well as any statements by witnesses that are not protected by the seal of confidentiality.
The Tribunal will notify both parties of its final decision in the case.
