Ex and I were married for a long time. We purchased some raw land and lived in mobile homes. We divorced in 2013. Part of the divorce decree was that she got to continue to live by herself on the land and we "remain joint co-owners" and "with each party having a 50% undivided ownership interest with a right of survivrorship". Her death in 2017 resulted in my 100% ownership. The raw land was sold in 2018 with no dwellings remaining. Can I calculate the cost basis for her 50% part of the land as the value of the land at the time of her death?
