Who deducts the mortgage interest after a divorce?

Final divorce decree 5/2025. Marital home was quit claimed deed to me. Mortgage is in both my name and my ex-husbands' name.  He will continue to make the PITI but I reimburse him for TI.  His payments are considered part of the marital asset distribution and not alimony.  Who can deduct the interest payments?  Who can deduct the taxes?
