Mont. Code § 32-1-501
Commercial banks, savings banks, trust companies, and investment companies may be dissolved in the manner provided by the laws of this state applicable to the dissolution of other corporations. However, a bank or trust company may, upon a vote of two-thirds of its stockholders at a special meeting called for that purpose in accordance with its bylaws, voluntarily quit business and liquidate upon the payment of its debts, exclusive of liability to stockholders, or upon agreement with all of its creditors to a plan of liquidation. A bank or trust company that wishes to voluntarily liquidate shall apply to the department for permission to liquidate and, in addition to complying with the laws of this state governing the liquidation of corporations, shall comply in all respects with the requirements or rules of the department governing voluntary dissolution. The board of directors of a bank or trust company whose stockholders have voted to place it in voluntary liquidation shall appoint a liquidating agent to wind up the affairs of the bank or trust company. The liquidating agent, on authority of the board of directors, may execute deeds for the transfer of real property and do all things necessary to carry out the proper liquidation of the bank or trust company. Nothing in this section prevents the department from taking charge at any time when in its opinion the interest of creditors or stockholders is not being protected. The decision of the department in these matters is controlling.
