Thanks for the info. You are correct that the mother is not currently filing a tax return and the father does not live with them. They are only Separated so there is no formal agreement on who can claim who but she has sole custody of the two children. I question the QC deduction being limited to them living with me however. It was my understanding that if you are providing more than half of their support it didn't matter where they lived in the same house or not. Thoughts?
