A more thorough explanation:

A trust estate is the property or assets that a trustee is responsible for managing on behalf of the beneficiaries of a trust. It is also known as the trust principal, trust fund, trust property, or trust res.

For example, if a person creates a trust and transfers their property into it, the trust estate would consist of that property. The trustee would then manage and distribute the property according to the terms of the trust for the benefit of the beneficiaries.

Another example would be if a parent creates a trust for their child's education. The trust estate would consist of the funds or assets that the parent transfers into the trust for the purpose of paying for the child's education expenses.

Overall, a trust estate is the property or assets that are held in trust and managed by a trustee for the benefit of the trust's beneficiaries.
