a paper return may take 4 to 6 weeks to process. also without claiming a dependent, assuming you usually file as head of household, you won't be able to use that filing status. it will have to be single which likely translates into a smaller initial refund. when going from not claiming a child to claiming a child an amended return is mandatory. if your ex doesn't voluntarily amend, then after a while, both parties get notices asking them to amend regarding claiming the child. if your ex doesn't do it with the first request, the IRS sends a second request asking for proof of eligibility to claim dependent. That's when you send in the documentation requested to prove you're the one that's entitled to claim.
