The key date is when title to the home was transferred to you, not the date of the divorce. You can still own property jointly even if you are divorced. Being responsible for paying the property tax, and being able to deduct it on an income tax return, are two different issues. You are both responsible for payment of the property tax up to the date that title was transferred. Whoever actually paid the property tax can claim the deduction on his or her income tax return.
If your divorce decree says anything about responsibility for paying the property tax, and you have questions about it, ask your divorce lawyer to clarify it. The divorce decree cannot override the income tax laws regarding who can claim a deduction.
