California Probate Code
(a) Subject to subdivision (c), a personal representative or trustee may make an irrevocable transfer to another adult or trust company as custodian for the benefit of a minor pursuant to Section 3909, in the absence of a will or under a will or trust that does not contain an authorization to do so.
(b) Subject to subdivision (c), a conservator may make an irrevocable transfer to another adult or trust company as custodian for the benefit of the minor pursuant to Section
(c) A transfer under subdivision (a) or (b) may be made only if all of the following requirements are satisfied:
(1) The personal representative, trustee, or conservator considers the transfer to be in the best interest of the minor.
(2) The transfer is not prohibited by or inconsistent with provisions of the applicable will, trust agreement, or other governing instrument. For the purposes of this subdivision, a spendthrift provision (such as that described in Section 15300) shall not prohibit or be inconsistent with the transfer.
(3) The transfer is authorized by the court if it exceeds ten thousand dollars ($10,000) in value; provided, however, that such court authorization shall not be required when the transfer is to a custodian who is either
(A) a trust company or (B) an individual designated as a trustee by the terms of a trust instrument which does not require a bond.
