My mom coerced my dying grandfather into signing his will in my name.

When my grandpa was sick, my mom influenced him in signing his property in my name only. My grandpa was bedridden and frail at that time. I did not know that he did that until after his death. Turns out that he left behind a lot of real estate properties and now my mom has full access to them since I'm just a minor. Both my aunt and uncle were left with nothing.<br><br>Edit: I'm 17 years old.
