Customs US border ....?

Dilemnia about crossing border..?

My husband and I are separated. I have been to court for custody and my case is uncontested. (My final court date is not until December. I have no papers until then saying I have full custody.) My parents live in the US and they want us to come for a visit (end of October). I have not heard nor seen my ex in one month and 5 days, no idea where he disappeared to..no contact. I know crossing the border (we are flying out of Buffalo)you need a consent from the other parents, saying its ok to take the child, etc. I get the point of it. We don't want people taking children when they shouldn't be. But if I have no clue where he is...how am I suppose to get that paper...

I have her birth certificate..the long form, saying I am the mother. I have her passport. I am going to go to the courthouse tomorrow to ask question regarding this but I wonder if anyone has been thru this or has some opinion.....thanks.
