§ 1311-b. Money judgment. If a claiming authority obtains a forfeiture judgment against a defendant for the proceeds, substituted proceeds, instrumentality of a crime or real property instrumentality of a crime, but is unable to locate all or part of any such property, the claiming authority may apply to the court for a money judgment against the defendant in the amount of the value of the forfeited property that cannot be located. The defendant shall have the right to challenge the valuation of any property that is the basis for such an application. The claiming authority shall have the burden of establishing the value of the property under this section by a preponderance of the evidence.
