File one Form 56 for the trust and another for the decedent. You can file them prior to filing the actual returns.
File a separate Form 56 for each person for whom you are acting in a fiduciary capacity. For example, if you will be filing the decedent’s final Form 1040 and are the executor/administrator of the decedent’s estate, file one Form 56 entering the name of the decedent as the person for whom you are acting and file one Form 56 entering the name of the estate as the name of the person for whom you are acting.
