Mont. Code Ann. § 33-2-1381

33-2-1381 . Domiciliary liquidators in other states. (1) The domiciliary liquidator of an insurer domiciled in a reciprocal state is, except as to special deposits and security on secured claims under 33-2-1382 (3), vested by operation of law with the title to all of the assets, property, contracts, and rights of action, insurance producers' balances, and all of the books, accounts, and other records of the insurer located in this state. The date of vesting must be the date of the filing of the petition if that date is specified by the domiciliary law for the vesting of property in the domiciliary state. Otherwise, the date of vesting is the date of entry of the order directing possession to be taken. The domiciliary liquidator has the immediate right to recover balances due from insurance producers and to obtain possession of the books, accounts, and other records of the insurer located in this state. The domiciliary liquidator also has the right to recover all other assets of the insurer located in this state, subject to 33-2-1382 .

(2) If a domiciliary liquidator is appointed for an insurer not domiciled in a reciprocal state, the commissioner of this state is vested by operation of law with the title to all of the property, contracts, and rights of action and all of the books, accounts, and other records of the insurer located in this state, at the same time that the domiciliary liquidator is vested with title in the domicile. The commissioner of this state may petition for a conservation or liquidation order under 33-2-1379 or 33-2-1380 or for an ancillary receivership under 33-2-1382 or, after approval by the district court, may transfer title to the domiciliary liquidator that the interests of justice and the equitable distribution of the assets require.

(3) Claimants residing in this state may file claims with the liquidator or ancillary receiver, if any, in this state or with the domiciliary liquidator if the domiciliary law permits. The claims must be filed on or before the last date fixed for the filing of claims in the domiciliary liquidation proceedings.
