No you can't file anything before the baby is born. Nor can joint custody be given to any of these people. They can file a third party custody action if they can show that neither parent is a fit parent. If that is proven than any one of them can have custody of the baby. The state will only take the baby is there is a reasonable fear of harm to the child.
