Sentinel Security Life provides its own letter-of-instruction/claim form. We prepare a transmittal cover letter and an enclosure checklist to accompany that form.

It depends on the capacity you are acting in. An executor or administrator encloses Letters Testamentary (when there is a will) or Letters of Administration (when there is not); a successor trustee encloses a certificate of trust; a successor under a small estate encloses that state’s small estate affidavit. The prepared letter lists the proof-of-authority document for your role alongside the institution’s required documents.

A letter of instruction is the written request an institution asks for when settling a deceased customer’s account. It identifies the decedent and the account, states the capacity you are acting in, and tells the institution what to do with the account.
