Such petition shall be filed in the court having jurisdiction over said conveyance, real property, monies or other things of value or having final jurisdiction over any related criminal proceeding brought under any provision of this chapter. In all such suits where 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 subparagraph (3), (5), or (7) of said subsection (a). The owner of said 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 (i). The court shall order the commonwealth to give notice by certified or registered mail to the owner of said conveyance, real property, moneys 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 two weeks after notice, hold a hearing on the petition. Upon the motion of the owner of said conveyance, real property, moneys 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 this chapter. 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 where a final order results in a forfeiture, said final order shall provide for disposition of said conveyance, real property, moneys 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.

The final order of the court shall provide that said moneys and the proceeds of any such sale shall be distributed equally between the prosecuting district attorney or attorney general and the city, town or state police department involved in the seizure. If more than one department was substantially involved in the seizure, the court having jurisdiction over the forfeiture proceeding shall distribute the fifty percent equitably among these departments.

There shall be established within the office of the state treasurer separate special law enforcement trust funds for each district attorney and for the attorney general. All such monies and proceeds received by any prosecuting district attorney or attorney general shall be deposited in such a trust fund and shall then be expended without further appropriation to defray the costs of protracted investigations, to provide additional technical equipment or expertise, to provide matching funds to obtain federal grants, or such other law enforcement purposes as the district attorney or attorney general deems appropriate. The district attorney or attorney general may expend up to ten percent of the monies and proceeds for drug rehabilitation, drug education and other anti-drug or neighborhood crime watch programs which further law enforcement purposes. Any program seeking to be an eligible recipient of said funds shall file an annual audit report with the local district attorney and attorney general. Such report shall include, but not be limited to, a listing of the assets, liabilities, itemized expenditures, and board of directors of such program. Within ninety days of the close of the fiscal year, each district attorney and the attorney general shall file an annual report with the house and senate committees on ways and means on the use of the monies in the trust fund for the purposes of drug rehabilitation, drug education, and other anti-drug or neighborhood crime watch programs.

All such moneys and proceeds received by any police department shall be deposited in a special law enforcement trust fund and shall be expended without further appropriation to defray the costs of protracted investigations, to provide additional technical equipment or expertise, to provide matching funds to obtain federal grants, or to accomplish such other law enforcement purposes as the chief of police of such city or town, or the colonel of state police deems appropriate, but such funds shall not be considered a source of revenue to meet the operating needs of such department.
