A transfer may be made only for one (1) minor, and up to two (2) persons may be the custodians. All custodial property held under this chapter by the same custodian or custodians for the benefit of the same minor constitutes a single custodianship. If more than one (1) person is appointed a custodian, such persons shall act as joint custodians under this chapter and, unless specified in any document creating the custodial property, each joint custodian shall have full power and authority to act alone with respect to the custodial property. If either joint custodian resigns, dies, becomes incapacitated or is removed, then the remaining one (1) of them may serve as sole custodian without the necessity of appointing a successor joint custodian.
