31 C.F.R. § 321.7
(c) Parent of a minor. Payment of a security bearing the name of a minor child, who is not of sufficient competency and understanding to sign the request for payment and comprehend the nature of the act, may be made to either parent with whom the minor resides or to whom custody has been granted, provided the form of registration does not indicate that a guardian or similar representative of the estate of the minor has been appointed or is otherwise legally qualified. Payment under this subsection may not be made to any person other than a parent. The parent requesting payment must sign the request for payment in the form, e.g., “John A. Jones, on behalf of John C. Jones.” The following endorsement must be typed or imprinted on the back of the security:
I certify that I am the (father or mother) of John C. Jones and the person (with whom he resides) (to whom custody has been granted). He is __ years of age and is not of sufficient competency and understanding to sign the request.
(e) Payment to a legal representative designated on a security by name and title. An agent may redeem a security registered in the name and title of a legal representative as defined in § 321.1, if the legal representative is known to the agent, or can establish identity in accordance with Treasury instructions and guidelines. The request for payment on the back of each security must be signed by the legal representative designated by name and title in the registration on the front of the security, or by a person authorized or empowered to act for a corporate legal representative so designated. The full title of the legal representative should be shown adjacent to each signature and, in the case of a corporate legal representative, the full corporate name, as well as the title, i.e., vice president, trust officer, etc., should be shown. Examples:
Henry C. Smith, conservator of the estate of John R. White, an adult, pursuant to Sec. 633.572 of the Iowa Code. Tenth National Bank by Arnold A. Ames, Vice President, guardian of the estate of Barry B. Bryan, a minor.
(f) Payment to a legal representative of a decedent's estate not designated on a security. An agent may redeem a security bearing the names of deceased persons in the registration, if the legal representative of the estate of the last deceased registrant:
(3) Presents acceptable evidence of the legal representative's appointment and of the dates of death of all persons named in the security's registration, in accordance with this part and the appendix.
In the case of a corporate legal representative, the full corporate name, as well as the title, must be shown. Examples:
John H. Smith and Charles N. Jones, co-executors of the will of Robert J. Smith, deceased. Tenth National Bank by John F. Green, Trust Officer, executor of the will of George N. Brown, deceased.
