Minn. Stat. § 345.515
It is unlawful for a person to seek or receive from another person or contract with a person for a fee or compensation for locating property, knowing it to have been reported or paid or delivered to the commissioner pursuant to chapter 345 prior to 24 months after the date the property is paid or delivered to the commissioner.
No agreement entered into after 24 months after the date the property is paid or delivered to the commissioner is valid if a person thereby undertakes to locate property included in a report for a fee or other compensation exceeding ten percent of the value of the recoverable property unless the agreement is in writing and signed by the owner and discloses the nature and value of the property and the name and address of the holder thereof as such facts have been reported. Nothing in this section shall be construed to prevent an owner from asserting at any time that an agreement to locate property is based upon an excessive or unjust consideration.
