12 CFR § 330.7 - Accounts held by an agent, nominee, guardian, custodian or conservator.
(a) Agency or nominee accounts. Funds owned by a principal or principals and deposited into one or more deposit accounts in the name of an agent, custodian or nominee, shall be insured to the same extent as if deposited in the name of the principal(s). When such funds are deposited by an insured depository institution acting as a trustee of an irrevocable trust, the insurance coverage shall be governed by the provisions of § 330.13.
(b) Guardian, custodian or conservator accounts. Funds held by a guardian, custodian, or conservator for the benefit of his or her ward, or for the benefit of a minor under the Uniform Gifts to Minors Act, and deposited into one or more accounts in the name of the guardian, custodian or conservator shall, for purposes of this part, be deemed to be agency or nominee accounts and shall be insured in accordance with paragraph (a) of this section.
(c) Accounts held by fiduciaries on behalf of two or more persons. Funds held by an agent, nominee, guardian, custodian, conservator or loan servicer, on behalf of two or more persons jointly, shall be treated as a joint ownership account and shall be insured in accordance with the provisions of § 330.9.
(d) Mortgage servicing accounts. Accounts maintained by a mortgage servicer, in a custodial or other fiduciary capacity, which are comprised of payments by mortgagors of principal and interest, shall be insured for the cumulative balance paid into the account by the mortgagors, up to the limit of the SMDIA per mortgagor. Accounts maintained by a mortgage servicer, in a custodial or other fiduciary capacity, which are comprised of payments by mortgagors of taxes and insurance premiums shall be added together and insured in accordance with paragraph (a) of this section for the ownership interest of each mortgagor in such accounts. This provision is effective as of October 10, 2008, for all existing and future mortgage servicing accounts.
(e) Custodian accounts for American Indians. Paragraph (a) of this section shall not apply to any interest an individual American Indian may have in funds deposited by the Bureau of Indian Affairs of the United States Department of the Interior (the “BIA”) on behalf of that person pursuant to 25 U.S.C. 162(a), or by any other disbursing agent of the United States on behalf of that person pursuant to similar authority, in an insured depository institution. The interest of each American Indian in all such accounts maintained at the same insured depository institution shall be added together and insured, up to the SMDIA, separately from any other accounts maintained by that person in the same insured depository institution.
