Land surveyors in Oklahoma: licensed PLS, land survey cost

Oklahoma licenses surveyors through the Oklahoma State Board of Licensure for Professional Engineers and Land Surveyors. The board works from Title 59 of the Oklahoma Statutes, Section 475.1 and following, together with its own administrative rules in Title 245 of the Oklahoma Administrative Code. The credential you want to see is Professional Land Surveyor, written PLS. Determining a property boundary, setting or restoring corner monuments and sealing a plat are licensed acts. A builder, a realtor or a fence contractor cannot do any of them for you, and a firm doing survey work needs its own Certificate of Authorization on top of the individual license.

You can check a name yourself. The board publishes current licensee and firm information through its portal at oklahoma.gov/pes, where you can confirm that an individual holds an active PLS license and that the firm quoting you holds a Certificate of Authorization. Check both. It is common in Oklahoma for a licensed surveyor to be the person in the field while the invoice comes from a company, and the company needs its own authorization number.

Oklahoma gives you a second, unusually direct way to check who did work on your land, and it is one almost nobody uses. Under the board's minimum standards, every monument an Oklahoma surveyor sets must carry a durable marker or cap bearing, at minimum, the license number of the surveyor in responsible charge or the Certificate of Authorization number of the firm. So if there is a capped pin at your corner, the number stamped into that cap tells you exactly who is responsible for it. Read the cap, then look the number up on the board portal. That is a five minute check that tells you whether the last survey of your property was done by somebody who is still in good standing.

On Surveyors.io that check is yours to make: a profile carries the number the surveyor entered, says on the page that we have not verified it, and this page links the board lookup so it takes a minute. Board checks and insurance certificates are planned, and this paragraph changes the day they run.

Not necessarily, and Oklahoma's own corner record instruction manual says so in one blunt line: a found half inch iron pin or mag nail is NOT an existent corner. That sentence is about public land survey corners specifically, and it is the single most useful thing an Oklahoma landowner can understand about their own back yard.

The reasoning runs through the classification system Oklahoma borrows from the 2009 BLM Manual of Surveying Instructions. An existent corner is one whose original position can be identified by substantial evidence of the original government monument or its accessories: an original stone or post, a bearing tree, field note calls. An obliterated corner is one where nothing remains at the original position but the position can still be proven from testimony, record evidence or reliable ties. A lost corner is one that cannot be proven either way and has to be restored by proportionate measurement. A piece of rebar somebody drove in at some point is evidence, and often good evidence, but it is not proof of the original position by itself.

Oklahoma courts settled the principle a century ago. In Fellows v. Willett, 224 P. 298 (Okla. 1924), the state Supreme Court held that the original section corners as established by the government survey, or the place where they were established if it can be definitely determined, "are conclusive on all present owners or holders with reference thereto, without regard to whether they were located correctly in the first instance." Read that carefully. Even if the 1870s surveyor measured badly, where he actually set the corner is the corner. Your deed does not describe a perfect rectangle on a map. It describes a position on the ground.

This is why the cheapest thing a neighbor can suggest, that the two of you split the difference between two pins and call it settled, is the most expensive thing you can do. To see what is genuinely in the ground before you order anything, start with how to find property pins.

Oklahoma is a public land survey system state, so most Oklahoma land is described in townships, ranges and sections rather than in pure metes and bounds. What surprises people is that Oklahoma runs off two principal meridians, and a legal description has to say which one applies.

The Indian Meridian, at longitude 97 degrees 14 minutes 30 seconds west, runs from the Red River to the Kansas line and, with the Indian Base Line at latitude 34 degrees 30 minutes north, governs all of Oklahoma east of 100 degrees west longitude. That is the whole state except the Panhandle. The grid runs twenty-nine townships north and nine south of the base line, and twenty-seven ranges east and twenty-six west of the meridian.

The Cimarron Meridian, at longitude 103 degrees west with its base line at latitude 36 degrees 30 minutes north, governs the Oklahoma Panhandle, with its initial point at the Panhandle's southwest corner. It was established by Richard O. Chaney and William W. Smith in the fall of 1881, and it was the last principal meridian established in the continental United States, a fair marker of how late the Panhandle was brought into the federal survey.

The effect is not academic. Township 3 North, Range 5 West exists in both systems and lands hundreds of miles apart, so a township and range call without its meridian is ambiguous. Anyone retracing your Oklahoma tract works back to the original government survey of the correct system. If your deed reads in section calls, how to read a plat of survey and how to read a survey legal description are the places to start.
