What must a will do to incorporate a trust?

To incorporate a trust within a will, it is essential for the will to clearly reference the trust and its terms. This is because the incorporation necessitates that the will explicitly acknowledges the existence of the trust documents and outlines how the trust is meant to function in relation to the overall testamentary scheme. By including a clear reference to the trust within the will, the testator ensures that their intentions regarding the trust are understood, guiding the executor in their duties to align with the terms of the trust.

The other options, while related to specific elements of trust and estate planning, do not fulfill the specific requirement of incorporation as specified in the question. A detailed list of all assets and beneficiaries is important for overall estate administration but is not a condition for trust incorporation. Specifying the trustee's authority for asset distribution is critical for trust management, but it does not establish how the trust is incorporated within the will. Lastly, stating the duration of the trust arrangement is relevant to the trust's effectiveness and compliance with legal standards, but it is not a requirement for integration into a will. Therefore, the critical aspect is the clear reference to the trust and its terms, ensuring coherence in the testator's intentions.
