Custody and claiming on taxes

My divorce was finalized Christmas Eve and we were given the typical each of you can claim a child this year for federal taxes. He texted me today and said that I could claim both kids as I’ve had them most of the time. Like there has been six one day visits for one kid, I know this meets the threshold for the irs, but it’s not what is in the decree. I don’t have time to fight fraud charges, so is the text enough? Location: Washington, so state income taxes do not apply.
