Minn. Stat. § 260C.303: VENUE.

Venue for proceedings for the termination of parental rights is either the county where the child resides or is found. However, if a court has made an order under the provisions of section 260C.201, and the order is in force at the time a petition for termination of parental rights is filed, the court making the order shall hear the termination of parental rights proceeding unless it transfers the proceeding in the manner provided in section 260C.121, subdivision 2.
