Which party benefits from a trust?

In a trust arrangement, the primary beneficiaries are those individuals or entities that receive the benefits or distributions from the trust as outlined by the trust document. The role of the beneficiaries is to receive the trust's assets or income, which is managed and safeguarded by the trustee. This is the core purpose of establishing a trust, to benefit the designated beneficiaries based on the intentions of the grantor or creator of the trust.

The other roles involved, such as the trustee, do have their significance in managing the trust, but they do not benefit from the trust in terms of receiving assets or financial rewards in the same way the beneficiaries do. The testator refers specifically to someone who has made a will, while an executor is appointed to administer the estate of a deceased person and also does not benefit directly from the trust. Thus, the correct answer emphasizes the role of the beneficiaries as the main recipients of the advantages provided by a trust.
