Do I have freedom to receive and review the will of any made after my fathers passing? I don’t know if anything was left to anyone. Or how to get it

My sister is trying to kick me out. Since my fathers passing, she’s been trying to. I’ll be working soon to help with rent but at the moment I don’t know if she was left things by word of mouth or if documentation’s were signed and given away. I don’t know this information or if I’m protected from eviction. Because right now, my name is listed as an occupant under the lease. She hasn’t switched it over, it’s still in his name. And I have no idea if she has the power to do this. But if she is power of attorney I do understand there’s nothing I can do. In what ways can I be protected?
