The Tribunal must notify the former spouse, who is called the "Respondent" or at least make the effort to do so. Church law and, indeed, basic justice require that you have the opportunity to know about the nullity petition and to defend the validity of the marriage. For this reason the Tribunal asked for your address or the name and address of someone through whom you can be reached by letter. While the Tribunal does ask that the Petitioner notify the Respondent to expect to receive a letter from the Tribunal, it does not require that the spouses have face-to-face contact in the Tribunal. But the Tribunal must make the effort to extend to you the right to be heard. This right to be heard includes the opportunity to know about the marriage, to name witnesses to be contacted, to be informed as to the progress of the case and to challenge the final decision. You may choose not to exercise this right to be heard; that choice will not prevent the Tribunal from completing its investigation. However, if you are denied the opportunity to be heard, you can challenge the final decision at any time in the future.
