I can give her another 8332 to Revoke the right that I previously granted. From the language on the form, I give her the Revocation 8332 (as I am entitled per Decree) to her this year 2017 it doesn't take effect till tax year 2018 which I would file in 2019. Wondering if I can use the Decree to override this waiting period so I can claim the dependent this year.
