History: A family member left me mineral rights that were named in her living trust. I am the trustee of the living trust. I used this documentation to transfer the mineral deed to my name. All documents were sent to McClain County Courthouse and they used this to issue the new mineral deed in my name. They also required her death certificate. I receive royalties.
Question: Is this sufficient to fulfill the requirements for verifying the title in the event I decide to sell my minerals?
I live in California.
