Before my grandpa passed away 10 years ago, he had my sign his will stating that I would receive a piece of land he has in TX. My uncle was named the executor because my mom wasn't trusted to take care of anything. Now, my uncle won't give me a copy of the will and says he should get the land because he's been paying the property tax on it all this time and he's the one that took care of my grandma after my grandpa died. So, acting entitled. My mom also conveniently forgot that my grandpa wanted me to have that land and saying she wants it. Any advice on what I can do? I know I signed that will, im nervous that my uncle May have altered it and I'll never see a copy of it.
