N.Y. Comp. Codes R. & Regs. tit. 2, § 100.4
(b) In addition to the foregoing, the following specific requirements should be fulfilled. (Although these requirements are set forth for the information and guidance of holders of State obligations, it should be recognized that additional requirements may be imposed by the State fiscal agent in any case, depending on the particular circumstances involved.)
(1) Agents or attorneys. No transfers of bonds will be made into the name of an individual, as agent or attorney. When bonds are presented for transfer and the assignment is executed by an agent or attorney of the registered owner, such assignment shall be by the agent or attorney in his representative capacity and there shall be submitted either the original power of attorney or a copy thereof certified under recent date (not more than 60 days). If the power of attorney has been filed as a public record, the official recorder shall make such certification, otherwise the certification shall be by: The full power of attorney (rather than an extract therefrom) should be submitted and proof given that the power of attorney has not been revoked by death or incompetency of the grantor, or a guaranty that the grantor is alive and competent shall be supplied.
(2) Committee for an incompetent. On transfers of bonds registered in the name of the committee for an incompetent person, there shall be submitted: The full court order (rather than an extract therefrom) shall be submitted. On transfers into such a registration, there shall be submitted a copy of appointment of the committee, certified under a recent date (not more than 60 days).
(3) Guardians. On transfers of bonds into or out of the name of a guardian, there shall be submitted: The full court order (rather than an extract therefrom) shall be submitted. If the transfer is from a guardian to his ward, evidence of termination of guardianship shall also be submitted.
(4) Estates of deceased persons.
(ii) On transfers out of the name of a decedent or out of the name of an executor, if the decedent died testate, the usual requirements are: If the decedent died intestate the requirements are usually similar to those imposed when the decedent died testate, as described in clauses (c), (d) and (e) of this subparagraph. In addition, a copy of the appointment of the administrator, certified under a recent date (not more than 60 days), shall be supplied. Additional requirements may be imposed in many cases.
(5) Trusts.
(i) On transfers of bonds into the name of a trustee, a certified copy of the will or other trust instrument must be submitted. Such certified copy will be returned if a plain copy is also submitted for retention by the State fiscal agent. The certification shall be made by:
(8) No change in ownership. An appropriate endorsement must be supplied on transfers of bonds involving a change of name but no change in ownership. In addition, an instrument shall be furnished setting forth the particulars of the change of name of the registered owner and guaranteeing to save the State and the State fiscal agent harmless from any loss or damage which may arise by reason of making the transfer requested. This instrument shall be executed by: If the change of name was authorized in court proceedings, a certified copy of the full court order (not an extract therefrom) shall be submitted. Certified copies of agreements of merger, consolidation, certificates of change of corporate name, etc., shall be submitted, if involved.
