Subdivision 1. Referee may not purchase property.

No referee, nor any person for the benefit of any referee, shall be interested, directly or indirectly, in any purchase of the premises sold.

Subd. 2. Other compensation.

This provision is not intended to prevent anyone from receiving compensation under chapter 82, and also payment for services as a referee appointed under this chapter, if the court determines that the referee services are beyond the usual broker services in connection with the sale of the property.
