If I was in that situation, I would let the Sovcit write whatever the hell they wanted on the paperwork just to give the judge a heads up as to what was coming.
They do have a point about not being told why though. I had two tickets a long time ago and nobody would tell me what they were for. They just wanted the money. If it’s in the system and you can see it on your computer it should also say what it is. That’s pretty ridiculous.
But I never had to dodge paying for the kids I had, so… Lol
