When an individual passes away, his/her will or trust identifies a representative to administer his/her estate. This representative is referred to as the executor (male) or executrix (female) and is generally approved or assigned by the local circuit court. The Internal Revenue Service tasks this representative to file a final personal return and information returns until the estate is completely transferred to the heirs.
The party that will take care of the assets is known as the Trustee in a Trust Agreement (Trust Document).
A trust is an agreement for one party to care for the assets of another party for the benefit of a third party. In essence, it is a business agreement. The person creating or the original owner of the assets is referred to as the Grantor. The party that will take care of the assets is known as the Trustee. The third party to receive the benefits is referred to as the Beneficiary.
