Deed-in-lieu Property Tax Help

I just went through a deed-in-lieu as a result of a divorce. I have property taxes owed for 2009. Am I still required to pay them? My mortgage company just stated they "will help me through this." I have already signed and returned the paperwork. Nothing in this paperwork stated anything about the property taxes owed. Upset this mortgage company did not work with the Obama Plan. I was left holding the house with supporting four other children. I wanted to try and sell it. My mortgage company (foreign owed, sorry if offending anyone here) refused to work with the plan stating to me "they were not required to accept that plan." I would like to know what to expect from the mortgage company since they have not been helpful in their answers. Thank you.
