And it is also unfortunate that the courts can be biased.. i hope that you get a decent judge that sees things your way.
What I think they should do, I don't think they do though, is look at prior history before separation/divorce. If the parents spent 50/50 with the kids then it should stay about that. In my case it was 90/10 the past 15 years so I think it should stay about that maybe 80/20 or something. Big changes in that I think are most likely due to financial or revenge using the kids as a pawn or some motive like that not love/interest of the kids.... Karen
