I will start this article off by giving one piece of advice that will make the world of difference in your family court experience: Set aside your differences and work with the other party in mediation.
One of the most common things you will hear in the court system is this, "its about the children" and all the courts decisions are based on what they determine to be in the best interest of the children and nothing more. That is a good premise, however it falls short of what is in the best interest of the family. I look at divorce differently now that I have been through it, divorce is not an end to a family - it only ends the joint decision making of the two adults, but those two adults will always remain a family unit through the children.
Whether you are on the child support end or not, no one wins in court, least of all the children. I have spent more money on lawyers, fees and support than I ever thought possible and to what end? I will tell you, so that my children know that I was there for them, that I did my best whether I agreed with the courts or their mother.
If you are considering divorce, for good reasons or not, do everything you can to minimize the harm to the children. If both parents can live a few blocks away from each other, attend the kids school activities and never say bad things about the other parents - than you will achieve a co-parenting plan that will best serve the children. My last bit of advice, life is too short to hold onto stress and anger about an ex-partner, move on an enjoy life as it can get better.
