Wolf- Note: My parents weren’t frum when the divorce proceeding started, so naturally they went to secular court. During the process, my mother and I became frum. When the judge asked to speak to me, I was already frum by that point. I suppose I should have refused to go, been convicted of contempt of court and been sent to juvenile detention.
When one his married civilly, besides the religious ceremony, then the parties MUST go to civil court to disolve the civil marriage. Dina d’malchusa dina.
