North Dakota Century Code Title 38. Mining and Gas and Oil Production § 38-02-11. Additional certificate to correct or extend boundaries may be filed by locator or assigns--Limitations

If the locator of any mining claim, or the locator's assigns, shall apprehend that the original certificate was defective, erroneous, or that the requirements of the law had not been complied with before filing, or is desirous of changing the locator's surface boundaries, or of taking in any part of an overlapping claim which has been abandoned, such locator or the locator's assigns may file an additional certificate subject to the provisions of this chapter. Such relocation may not interfere with the existing rights of others at the time of such relocation. No such relocation, nor the record thereof, may preclude the claimant from proving any such title as the claimant may have held under previous locations.
