I never probated my Mother's 2011 will. What do I need to do to get her house put in my name? I continue to live in the house.

I shared the house with my Mother at the time of her death and continue to live in it today. But due to my financial situation, I never had her will probated. Because of my advancing age and poor health, I am considering selling the house to downsize but it's still in my Mother's name since the death of her husband(my Father)in 1980, who had no will. I have been told I need to file an Affidavit of Heirship pursuant to TCA 30-2-712 but do I have to probate her will before I can do this?
