Legal Question in Wills and Trusts in California

I'd have to review the instruments to be sure, but from your manner of describing it, the home is in a trust, and is not subject to the will. That would be different if the trust you describe is what is known as a testamentary trust, in which the will sets up and funds the trust upon the death of your father. But if he put the house into a trust, and the trust became irrevocable, the trust instrument controls, and is not subject to the will. In that situation, the home is adeemed by extinction, and you have to comply with the trust instrument, called the declaration of trust.
