Mont. Code Ann. § 32-1-426

32-1-426 . Deposit of securities in central depository. (1) Notwithstanding any other provision of law, any fiduciary, as defined in 32-1-425 , holding securities in its fiduciary capacity, any bank or trust company holding securities as a custodian or managing agent, and any bank or trust company holding securities as custodian for a fiduciary is authorized to deposit or arrange for the deposit of the securities in a clearing corporation, as defined in 30-8-112 . When the securities are deposited, certificates representing securities of the same class of the same issuer may be merged and held in bulk in the name of the nominee of the clearing corporation with any other securities deposited in the clearing corporation by any person regardless of the ownership of the securities, and certificates of small denomination may be merged into one or more certificates of larger denomination. The records of the fiduciary and the records of the bank or trust company acting as custodian, as managing agent, or a custodian for a fiduciary must show at all times the name of the party for whose account the securities are deposited. Title to the securities may be transferred by bookkeeping entry on the books of the clearing corporation without physical delivery of certificates representing the securities. A bank or trust company depositing securities pursuant to this section is subject to rules, which in the case of state-chartered institutions, the department and, in the case of national banking associations, the comptroller of the currency, may from time to time adopt. A bank or trust company acting as custodian for a fiduciary shall, on demand of the fiduciary, certify in writing to the fiduciary the securities deposited by the bank or trust company in the clearing corporation for the account of the fiduciary. A fiduciary shall, on demand by any party to a judicial proceeding for the settlement of the fiduciary's account or on demand by the attorney for the party, certify in writing to the party the securities deposited by the fiduciary in the clearing corporation for its account as the fiduciary.

(2) This section applies to any fiduciary holding securities in its fiduciary capacity and to any bank or trust company holding securities as a custodian, managing agent, or custodian for a fiduciary regardless of the date of the agreement, instrument, or court order by which it is appointed and regardless of whether or not the fiduciary, custodian, managing agent, or custodian for a fiduciary owns capital stock of the clearing corporation.
