Success is measured by the petitioner only? What about the spouse who contested the annulment, like Sheila Rauch Kennedy?
Honestly, so far I haven’t read any actively contested cases. But I personally would count as a success in this process any couple who reconciles and withdraws their paperwork. Unfortunately, I don’t know how many pastors are out there actively trying to reconcile people who have already had a civil divorce. (A civil divorce is a pre-requisite to filing a petition in LA.)
