## How land is surveyed in Oklahoma

PLSS throughout, on two grids that do not connect. Here is what the legal description on your deed, lease or division order is actually telling you, and where to check it for free.

**Oklahoma uses public land survey system.** PLSS throughout, on two grids that do not connect.

## The principal meridians

A principal meridian and its base line are the origin of a rectangular survey. Township and range numbers count outward from that origin, which means the same township and range numbers repeat under every meridian. The meridian is the part of the description that says which grid you are on.

- **Indian Meridian** (1870). Governs all of Oklahoma except the Panhandle. Its initial point sits about a mile south of old Fort Arbuckle, roughly six miles west of Davis in Murray County.

- **Cimarron Meridian** (1881). Governs the Panhandle, the old No Man's Land. Its initial point is where 103 degrees west longitude meets 36 degrees 30 minutes north latitude. The 103rd was run twice before and missed both times, by about four miles in 1857 and about two and a half in 1859.

## Allotment land does not behave like homestead land

Much of eastern Oklahoma passed by Indian allotment rather than by homestead patent, so it will not appear in BLM's General Land Office records at all. Title for trust and restricted allotted land is recorded federally with the BIA Land Titles and Records Office, which is a separate system from both the county clerk and BLM.

## What we see go wrong in Oklahoma

Almost every Oklahoma description ends in I.M. or C.M., and that suffix is not decoration. A T2N-R5E in the Panhandle is entirely different ground from a T2N-R5E under the Indian Meridian. If a description reaches us without the meridian and the county is in the Panhandle, we go find it before we do anything else.

## Where to look it up, free

- [BLM General Land Office Records](https://glorecords.blm.gov). Original federal patents in what was Oklahoma Territory

- [BIA Land Titles and Records Office](https://www.bia.gov/bia/ots/dtaot/bltr). The federal office of record for trust and restricted allotted land

Deeds are with the 77 county clerks. There is no free statewide Oklahoma land records search.

### Send us the description and we will read it back to you.

What it covers, how many net mineral acres it actually is, and whether anything is producing on it. Free, no obligation, and the answer does not change if you never sell anything to us. We do this every day and it usually takes us an hour.

Compiled from BLM, state land offices, state archives and statute, current as of 2026-08. Berlin Royalties is a mineral buyer and a landman shop in Tulsa, not a law firm or a licensed surveyor. Nothing here is a boundary opinion, and a description that matters to a transaction should be run by a title attorney or a licensed surveyor in the state where the land sits.
