Yes that is exactly what he wants to do and is asking me to allow it. I politely told him no because I was uncomfortable with the whole thing. What makes me nervous is this is the first year he's ever asked (except for the year she was born), he is REALLY pushing this, and told me he already "ran it through Turbo Tax". I even offered to voluntarily rotate years starting next year if he provided some support, even a few dollars and contributions to school expenses etc, but he said that would never work because he couldn't spare even a few dollars per month towards support. I really try to work things out amicably with him but sometimes he really doesn't want to see the bigger picture *sigh*
This COULD mean that he has already done so--completed his taxes and e-filed claiming the child.
You need to file quickly, claim your child and let the IRS sort out the mess he is trying to make.
