California Probate Code
Sec. § 15400

Unless a trust is expressly made irrevocable by the trust instrument, the trust is revocable by the settlor. This section applies only where the settlor is domiciled in this state when the trust is created, where the trust instrument is executed in this state, or where the trust instrument provides that the law of this state governs the trust.
