Filing for custody is the easy part. The courts have a self help section where attorneys who volunteer their timewill guide you and the court can waive the fees but you have to apply for that. The next problem is visitation. The court will not deny visitation to the father with out good reason. He has as much rights to the children as you do. I would have a visitation plan figured out and its usually everyother weekend and alternating holidays. With specific reasons you can ask for parenting classes on his part and monitored visitation. Monitored by the courts or grandparents etc. Be prepaired for a fight sepecially if he wants the children more. He has a job and can provide for them if they were with him. He even could hire a nanny. Child support is figured out bi the disomaster program. Pretty basic. Another thing -if he is angry with you, you just might concider a mutual drop off .Grandparents house is great and the grandparents can do the switch. Make the best of it to get along with him. This will be going on for the next 18 years. Good luck
