Hi

I live in PA. Divorced in 2015. My ex (female) and I (male) are BOTH on the title and mortgage of the house. Ex lives in the house with primary care of the kids. I live elsewhere and pay her alimony and child support. From the alimony, child support, and what money she makes herself, she pays the entire mortgage. Am I eligible to claim any of the mortgage interest or real estate tax for my tax deductions?

Thank you!!
