No matter what, you have to give him permission. and he will have to have you either there to say its alright or a letter of some kind approving it.
Yep. if she has shared "control" of the daughter.
Yes as long as YOY have joint custody and he is on birth certificate and if you give him permission.
He will have to have signed letter of authorization from you giving permission.
