I got divorced in December 2018. We had online savings accounts, in my ex's name. In the decree, it says I am responsible for x percent of the interest earned of one of the accounts. She received the 1099 INT in her name. How am I suppose to claim the interest, just calculate how much interest I am suppose to claim and act as I got a 1099 from them and enter it? Or does she have to file for the amount on her 1099 and I have to pay her? Not sure how to go about paying my share. Thanks....
