This is a very bizarre story, I can't quite work out what's happened but someone has committed some kind of fraud and identity theft??
However, this has absolutely nothing at all to do with the difficulty other parents face getting maintenance payments.
Men (almost always men)who don't pay maintenance rarely do so because they have grounds to doubt the existence of their child. They do so because they are greedy, mean twats.
To claim this case has anything to do with the difficulty some women face over maintenance is a really convuluted way to twist everything round into being a woman's fault somehow.
