@macuser_22 thanks for the info. It's so complicated, but didn't know I'd get a refund before an investigation. But it'll still be a lot of work for him to amend, me to paper file and deal with this down the road again. Plus I don't want him in trouble we just never discussed how we'd proceed after he moved. I think we're in agreement that he'll keep his return as is and claim the child exemption, I'll do that form 88## & adjust mine, since I haven't filed yet. I'll take the child earn income credits & keep HOH status. Then he said he'll give me a percentage of the difference of my refund for not claiming our son and the $500 stimulus he already received for him. And we'll write a new agreement for me to claim from now on and file it as an amendment. He said it's the best way since he's filed & gotten the refund already.
