My wife had 2 children with her ex. we live in the state of colorado. the parenting agreement does not state which person may claim the children. he has claimed them for the past 5 years at least. However we have them more than 50% of the time. He claimed them again this year. If I file our taxes without the children can I amend the taxes to include the children? is there anything that we will need to do to claim them?
