Is the only qualified owner of an IRA an individual personally? If the funds used to create an IRA or a Roth IRA came from a trust classified as a "grantor trust", would the trust be treated as the owner? I am aware this type of trust can be the beneficiary. This question is on the technical side of distinguishing the owner from the beneficiary.

Only an individual can own an IRA. A revocable trust cannot be the owner.
