A personal representative or trustee may make an irrevocable transfer pursuant to § 64.2-1908 to a custodian for the benefit of a minor as authorized in the governing will or trust. If the testator or settlor has nominated a custodian under § 64.2-1902 to receive the custodial property, the transfer shall be made to that person. If the testator or settlor has not nominated a custodian under § 64.2-1902 or all persons so nominated as custodian die before the transfer or are unable, decline, or are ineligible to serve, the personal representative or the trustee shall designate the custodian from among those eligible to serve as custodian for property of that kind under subsection A of § 64.2-1908.
