My grandfather died in 2001 and created a "living trust" for the lifetime use of my Grandmother, however, the assets in my grandfathers living trust transferred to the name of his three children, including my father. In 2005 my grandmother added a codicil to her will providing that my fathers portion of his inheritance would go to my mother if he dies. He died in 2008. My grandmother died in 2013. Does the portion of the estate that was in a living trust from my grandfather also go to my mother?
