My aunt died. She was 96 years old. Back in the 90s, she told me that she had left me a little something, upon her passing. I am going to her bank with a copy of her Death Certificate. She left no will, but I am the sole beneficiary of her Revocable Trust.

Question: what is a revocable trust? And, as beneficiary, will I have a problem at her bank with collecting whatever? Do I need to take a certified copy of her Death Certificate with me?
