Can a will convey ownership of a house in an irrevocable Trust?

A will cannot convey ownership of a house that is held in an irrevocable trust because the trust itself determines the ownership and management of the property. Once a property is placed in an irrevocable trust, the grantor relinquishes control over it, and any changes to its ownership must be made according to the trust's terms. Therefore, the house would remain under the trust's provisions after the grantor's death, rather than being transferred via a will.
