Locate the original trust document, which should be among the decedent's personal papers or with his attorney. Once the document is available, verify your status as successor trustee.
Obtain a certified copy of the death certificate from the county clerk. This document is often required to establish to third parties that you are authorized to act as the successor trustee.
Prepare a trust certificate to give to others holding estate property, such as banks, as well as the government agency responsible for recording documents related to ownership of real estate. In most cases, a bank or government agency will have a pre-printed document for you to use.
Prepare an affidavit of death of trustee for filing with the county clerk in any county where the decedent owned real estate. The county clerk's office typically provides a form for this purpose.
Sign your name on all trust-related documents in a manner that reflects your position as trustee, such as "Robert P. Jones, trustee of the Jones Family Trust."
