Child passport issues

Hi mummies, I wrote in a couple of weeks ago, asking about other mummies experiences with getting a child's passport. I am still having trouble getting this passport for my 4 yr old. It doesn't matter how many legal documents I sign, they will not believe me when I say that her "father" has never met or communicated with her, and there are no court orders and no child support being paid because I was given an exemption. I even provided a copy of the divorce papers with him stating she isn't his child and he is not listed on the birth certificate. I have been told that it is because I was married to him when she was born and that is why I am having trouble getting the passport. Have any other mummies been in the same position, ie, been married at the time, father has never had contact etc, and gotten the passport. I am at the end of my rope. Help!!!!!!!!!
