Section 56. (a) The following property shall be subject to forfeiture to the commonwealth and all property rights therein shall be in the commonwealth:

(i) all conveyances, including aircraft, vehicles or vessels used, or intended for use, to transport, conceal or otherwise facilitate a violation of section 50 or 51;

(ii) all books, records and research, including microfilm, tapes and data which are used, or intended for use, in violation of section 50 or 51;

(iii) all negotiable instruments, securities or other things of value furnished or intended to be furnished by any person in exchange for forced labor or services or sexual servitude, all proceeds traceable to such an exchange, including real estate and any other thing of value, and all negotiable instruments and securities used or intended to be used to facilitate any violation of section 50 or 51; and

(iv) all real property, including any right, title and interest in the whole of any lot or tract of land and any appurtenances or improvements thereto, which is used in any manner or part to commit or to facilitate any violation of section 50 or 51.

No forfeiture under this section shall extinguish a perfected security interest held by a creditor in a conveyance or in any real property at the time of the filing of the forfeiture action.

(b) Property subject to forfeiture pursuant to clauses (i) to (iv), inclusive, of subsection (a) shall, upon motion of the attorney general or district attorney, be declared forfeit by any court having jurisdiction over said property or having final jurisdiction over any related criminal proceeding brought under this section.

(c) The court shall order forfeiture of all conveyances and real property subject to forfeiture under this section, except as follows:

(i) no conveyance used by any person as a common carrier in the transaction of business as a common carrier shall be forfeited unless it shall appear that the owner or other person in charge of such conveyance was a consenting party or privy to a violation of section 50 or 51;

(ii) no conveyance shall be forfeited by reason of any act or omission established by the owner thereof to have been committed or omitted by any person other than such owner while such conveyance was unlawfully in the possession of a person other than the owner in violation of the criminal laws of the United States, of the commonwealth or of any state; and

(iii) no conveyance or real property shall be subject to forfeiture unless the owner thereof knew or should have known that such conveyance or real property was used in violation of section 50 or 51.

(d) A district attorney or the attorney general may petition the superior court in the name of the commonwealth in the nature of a proceeding in rem to order forfeiture of a conveyance, real property or other things of value subject to forfeiture under subsection (a). Such petition shall be filed in the court having jurisdiction over the conveyance, real property or other things of value or having final jurisdiction over any related criminal proceeding brought under section 50 or 51. In all such suits in which the property is claimed by any person, other than the commonwealth, the commonwealth shall have the burden of proving to the court the existence of probable cause to institute the action, and any such claimant shall then have the burden of proving that the property is not forfeitable pursuant to subsection (c). The owner of the conveyance or real property, or other person claiming thereunder, shall have the burden of proof as to all exceptions set forth in subsections (c) and (j). The court shall order the commonwealth to give notice by certified or registered mail to the owner of the conveyance, real property or other things of value and to such other persons as appear to have an interest therein, and the court shall promptly, but not less than 2 weeks after notice, hold a hearing on the petition. Upon the motion of the owner of the conveyance, real property or other things of value, the court may continue the hearing on the petition pending the outcome of any criminal trial related to the violation of sections 50 or 51. At such hearing, the court shall hear evidence and make conclusions of law, and shall thereupon issue a final order from which the parties shall have a right of appeal. In all such suits in which a final order results in a forfeiture, the final order shall provide for disposition of the conveyance, real property or any other thing of value by the commonwealth or any subdivision thereof in any manner not prohibited by law, including official use by an authorized law enforcement or other public agency, or sale at public auction or by competitive bidding. The proceeds of any such sale shall be used to pay the reasonable expenses of the forfeiture proceedings, seizure, storage, maintenance of custody, advertising and notice and the balance thereof shall be distributed as further provided in this section.

(e) The final order of the court shall be deposited into the Victims of Human Trafficking Trust Fund established in section 66A of chapter 10.

(f) Any officer, department, or agency having custody of any property subject to forfeiture under this section or having disposed of the property shall keep and maintain full and complete records showing from whom it received the property, under what authority it held or received or disposed of said property, to whom it delivered the property, the date and manner of disposition of the property, and the exact kinds, quantities and forms of the property. The records shall be open to inspection by all federal and state officers charged with enforcement of federal and state human trafficking laws. Persons making final disposition of the property under court order shall report, under oath, to the court the exact circumstances of such disposition.

(g) During the pendency of the proceedings, the court may issue at the request of the commonwealth ex parte any preliminary order or process as is necessary to seize or secure the property for which forfeiture is sought and to provide for its custody including, but not limited to: an order that the commonwealth remove the property if possible and safeguard it in a secure location in a reasonable fashion; that monies be deposited in an interest-bearing escrow account; and that a substitute custodian be appointed to manage such property. Property taken or detained under this section shall not be repleviable, but once seized shall be deemed to be lawfully in the custody of the commonwealth pending forfeiture, subject only to the orders and decrees of the court having jurisdiction thereof. Process for seizure of the property shall issue only upon a showing of probable cause, and the application therefore and the issuance, execution and return thereof shall be subject to chapter 276, so far as applicable.

(h) A district attorney or the attorney general may refer any real property, and any furnishings, equipment and related personal property located therein, for which seizure is sought, to the division of capital asset management and maintenance office of seized property management, established under section 47 of chapter 94C. The office of seized property management shall preserve and manage the property in a reasonable fashion and dispose of the property upon a judgment ordering forfeiture, and to enter into contracts to preserve, manage and dispose of the property. The office of seized property management may receive initial funding from the special law enforcement trust funds of the attorney general and each district attorney under paragraph (f) and shall subsequently be funded by a portion of the proceeds of each sale of such managed property to the extent provided as payment of reasonable expenses in paragraph (d).

(i) The owner of any real property which is the principal domicile of the immediate family of the owner and which is subject to forfeiture under this section may file a petition for homestead exemption with the court having jurisdiction over such forfeiture. The court may, in its discretion, allow the petition exempting from forfeiture an amount allowed under section 1 of chapter 188. The value of the balance of the principal domicile, if any, shall be forfeited as provided in this section. Such homestead exemption may be acquired on only 1 principal domicile for the benefit of the immediate family of the owner.

(j) A forfeiture proceeding affecting the title to real property or the use and occupation thereof or the buildings thereon shall not have any effect except against the parties thereto and persons having actual notice thereof, until a memorandum containing the names of the parties to such proceeding, the name of the town wherein the affected real property lies, and a description of the real property sufficiently accurate for identification is recorded in the registry of deeds for the county or district wherein the real property lies. At any time after a judgment on the merits, or after the discontinuance, dismissal or other final disposition is recorded by the court having jurisdiction over such matter, the clerk of such court shall issue a certificate of the fact of such judgment, discontinuance, dismissal or other final disposition, and such certificate shall be recorded in the registry in which the original memorandum recorded pursuant to this section was filed.
