Any pointers on how to factor individual and real estate taxes that have accrued during period of separation? We will likely finalize divorce by the end of 2023.

I moved out of our joint mortgage home in March 2023 and have helped cover mortgage payments since then (which include escrow $$ for taxes). My STBXW is a contract employee (attorney) and it's been hard to tell whether she is setting aside $$ to pay for her income taxes.

We are working through agreeing on dividing our assets and my STBXW is (somewhat understandably) pushing for me to help pay for any out of pocket taxes due for the house / her income. My lawyer isn't sure how to help with this one. Our accountant if my STBXW's dad's best friend so he's not exactly neutral. Any help would be appreciated.

Thank you
