Depends on what state you live in. I would google that and the city you live in. I work in Civil cases and a settlement conference is to update the judge and let him know if the parties are able to settle. He may order mediation if he thinks so or will set it for trial if not. I do not see it being a hearing to determine custody, etc though if there are any issues you need brought up, do so. Be prepare as if you were going to trial and you will have everything covered. Have proof of supports, visits, time spent etc. Be prepared to answer any question the judge may have on how if and when you care for the kids. I would go so far as to know docs names, etc. Thats just me though, I do it for a living so I have to prepare for everything. Let me know if I can help.
