A trust is a legal arrangement that provides for the ownership, management, and distribution of property. Think of a trust as a box into which someone places property. The person placing the property into the trust is known as the grantor of the trust. The person that oversees the property in the box is the trustee. Finally, the person who receives the benefit of the property held in the box is known as the beneficiary.
A revocable trust is a trust whereby provisions can be altered or canceled dependent on the grantor. During the life of the trust, income earned is distributed to the grantor, and only after death does property transfer to the beneficiaries. This type of agreement provides flexibility and income to the living grantor; he is able to adjust the provisions of the trust and earn income, all the while knowing that the estate will be transferred upon death.
