Which document typically establishes a trust?

The document that typically establishes a trust is the trust agreement. This legal document outlines the specific terms of the trust, including how the assets within the trust are to be managed, who the beneficiaries are, and the duties of the trustee. A trust agreement is essential for defining the intentions of the person creating the trust (the grantor or settlor) and ensuring that the trust is administered according to their wishes.

In contrast, a will is designed to distribute a person's assets after their death but does not set up a trust by itself. An easement is a right to use someone else's property for a specific purpose and does not have any relation to creating a trust. A purchase agreement, on the other hand, is a contract detailing the sale of real estate and also does not relate to establishing a trust. Therefore, the trust agreement is the correct answer as it directly serves the purpose of establishing a trust.
