Effective - 28 Aug 1989   404.565. Multiple beneficiaries of custodial property, administered, how — termination of custodianship, death of beneficiaries, effect. — 1. During the lifetimes of multiple beneficiaries, ownership of custodial property between a husband and wife is presumed to be held as tenants by the entireties and among other persons, custodial property is presumed to be of equal undivided interests in the custodial property which are indefeasibly vested in the beneficiaries as tenants in common, subject to the provisions of sections 404.400 to 404.650, unless the title document provides otherwise or there is clear and convincing written evidence of a different intent of the beneficiaries or the persons creating the personal custodianship.  2. Unless held for a husband and wife as tenants by the entireties or otherwise directed by the beneficiaries or governed by a custodial agreement, the personal custodian shall administer the custodial property as separate undivided interests for the use and benefit of the custodial beneficiaries during their lifetimes and shall separately account to each beneficiary for the administration of the beneficiary's interest in the custodial property.  3. During the lifetimes of the multiple beneficiaries, the personal custodian shall follow the directions of the beneficiaries who are not incapacitated. If one of the beneficiaries becomes incapacitated, the personal custodian shall follow the directions of the beneficiaries who are not incapacitated to the extent that the directions do not conflict with the rights of the incapacitated beneficiary in the custodial property.  4. If one of two or more beneficiaries who has a right to sever his or her interest in the custodial property demands termination of the personal custodianship, the personal custodian shall deliver to the terminating beneficiary custodial property in an amount equal in value to the beneficiary's interest in the custodial property, free and clear of the custodianship, and the custodianship continues for the remaining beneficiaries.  5. At death of one of two or more beneficiaries who hold their interest in the custodial property as tenants in common, the interest of the decedent in the custodial property shall be distributed in accordance with a transfer on death direction executed under subsection 2 of section 404.560 and, if none, to the decedent's estate.  6. At death of one of two or more beneficiaries, who hold their interests in the custodial property as joint tenants with right of survivorship or as tenants by the entirety, the custodial property belongs to the surviving beneficiary or beneficiaries as against the estate of the decedent. If there are two or more surviving beneficiaries, their respective ownerships during lifetime shall be in proportion to their previous ownership interest, augmented by an equal share for each survivor of any interest the deceased beneficiary may have owned in the custodial property immediately before death, unless the decedent is the spouse of a beneficiary, in which case, the interest owned by the decedent shall be applied solely to augment the ownership interest of the surviving spouse in the custodial property, and the right of survivorship continues as between the surviving beneficiaries. When only one of two or more beneficiaries survives, the personal custodianship shall in all respects become a personal custodianship of property for a single individual. ­­-------- (L. 1989 H.B. 145)
