you entered into a divorce or separation agreement on or
before December 31, 2018, and the agreement is
changed after December 31, 2018, to expressly provide
that alimony received is not included in your former spou-
se’s income. Alimony paid is not deductible if you entered
into a divorce or separation agreement after December
