thank you @xmasbaby0 we had just a verbal agreement more like he always said he claimed the youngest child I claimed the oldest, because they lived at both locations more on his end. But based on our divorce decree he and I have joint legal custody however it was me that was named to file both children each year. I was suppose to sign a form as the custodial parent and I never did. But sounds like to me if he tries to file him next year or even this child tax credit he will have to pay it back. It is 206 days left in the year and I will have him the remaining of the year.
