There are two types of custody, physical and legal. Legal custody concerns joint decision making in the child's life including health care, so if you have joint legal custody, the father has the right to object to you taking such an action and it would have to be court ordered otherwise.
Joint legal custody, no, not if the other parent objects. You must secure their permission or failing that, the permission of the court which is the only authority that may override a parent's objections in such a situation.
No, you can not, unless the custody order is modified by the court.
In joint legal, the primary residential can.
With an injunction
No, and it would be horrible for the child.
what type of mother would want this to happen ..if he is good enough to have joint custoday of his kids then why in the world would you want to give your kids to someone other then him
The same rights as you.
Yes. With joint custody either parent can change the kids school or any major desicion. The ideal relationship you would both agree on this but reality is always different.
As in you remarried your children's mother, or a woman with children?
Should not affect it, and besides, it's for the kids benefit.
Get a current copy of the custody order from the Clerk of the Court and take police with you to pick up the children.
Why would you want it? Joint custody is best for the kids.
