C.R.S. § 38-44-101: When action may be brought.

When one or more owners of land, the corners and boundaries of which are lost, destroyed, or in dispute, desire to have the same established, they may bring an action in the district court of the county where such lost, disputed, or destroyed corners or boundaries or parts thereof are situated against the owners of the other tracts which would be affected by the determination or establishment thereof, to have such corners or boundaries ascertained and permanently established. If any public road is likely to be affected thereby, the proper county shall be made a party defendant.
