I Want To Carry My Daughter On My Income Tax Return,I Pay Child Support And Is And Allways Current. How Do I Find Out Who Is Carrying Her On Their Taxes? Is There A Website I Can Go To And Check?

There is no website to check, and the IRS is very reticent about providing that information. The only other person who can claim your daughter is your ex-spouse, or perhaps her parents.

You need to coordinate with him/her as to who is going to claim her.

Trying to do it behind your ex-spouse's back is NOT a good idea and will only cause problems.
