A Qualified Domestic Relations Order does not mean Alimony.
Check with your attorney, but usually a Court-Appointed Apportionment cannot be treated as alimony and is taxable.
According to the Office of Personal Management:
“Your former spouse must report the amount of apportionment they receive as taxable income and is required to pay taxes on this income. Apportionment payments cannot be used as alimony deductions on a tax return.”
