Nebraska Statutes: 17-415
17-415. Additions; plat; contents; duty to file. Every original owner or proprietor of any tract or parcel of land, who shall subdivide the same into two or more parts for the purpose of laying out any city or village or any addition thereto or any part thereof, or suburban lots, shall cause a plat of such subdivision, with references to known or permanent monuments, to be made, which shall accurately describe all subdivisions of such tract or parcel of land, numbering the same by progressive numbers, and giving the dimensions and length and breadth thereof, and the breadth and courses of all streets and alleys established therein. Descriptions of lots or parcels of land in such subdivisions, according to the number and designation thereof on such plat contained, in conveyances or for the purposes of taxation, shall be deemed good and valid for all purposes. The duty to file for record a plat as provided herein shall attach as a covenant of warranty in all conveyances hereafter made of any part or parcel of such subdivision by the original owners or proprietors against any and all assessments, costs and damages paid, lost or incurred by any grantee or person claiming under him, in consequence of the omission on the part of the owner or proprietors to file such plat.
