Land-Buying Glossary for Oklahoma: The Terms on Listings, Surveys and Deeds

By Seth Willyard, Blue River Realty

This glossary defines the terms a first-time buyer meets on an Oklahoma land listing, a survey, a deed and a title commitment. The definitions are written in plain English and grouped by topic, so you can read the section that matches the document in front of you. Where Oklahoma has a specific rule, the definition says so and the source is listed at the end.

It is part of our Oklahoma recreational land guide. Definitions are general information, not legal advice. For the wording of a specific deed, easement or contract, use an Oklahoma real estate attorney.

Measuring land

• Acre. 43,560 square feet. A square acre is about 208.7 feet on a side. See how big 5, 10, 20 and 40 acres are.
• Chain. A surveyor's unit of 66 feet. Ten square chains make one acre. Old deeds and plats often give distances in chains.
• Rod (pole, perch). 16.5 feet, a quarter of a chain.
• Section. A unit of the public land survey, nominally one mile square and 640 acres. Actual sections can run over or under.
• Quarter section. 160 acres, half a mile on a side.
• Quarter-quarter (a "forty"). 40 acres, a quarter mile on a side.
• More or less. Words after an acreage in a deed ("10 acres, more or less") signaling that the stated area is approximate. The survey controls.

Describing land

• Tract. A piece of land sold as one unit. Also called a parcel. In a development, tracts are usually numbered on a plat.
• Lot. A numbered piece of land on a recorded plat. In the public land survey, "lot" also means an irregular fractional piece of a section.
• Legal description. The wording in a deed that identifies exactly which land is conveyed. A street address or a parcel number is not a legal description.
• Section-township-range. The public land survey way of locating land. A township is about six miles square and holds 36 sections, numbered from the northeast corner back and forth to the southeast corner. A description reads from small to large, for example the NE/4 of the SW/4 of Section 12, Township 4 North, Range 22 East.
• Indian Meridian (I.M.). The north-south reference line, with the Indian Base Line, from which all of Oklahoma except the Panhandle is surveyed. The initial point is near old Fort Arbuckle in Murray County. Oklahoma legal descriptions outside the Panhandle end with "I.M." or "Indian Meridian."
• Aliquot part. A piece of a section described by halves and quarters, such as "the N/2 of the SE/4."
• Metes and bounds. A description that starts at a known point and follows the boundary by direction and distance ("thence North 89 degrees East 660 feet") back to the start. Used for tracts that do not fit the grid.
• Plat. A drawn map of a survey or subdivision showing tracts, dimensions, roads and easements. A recorded plat is filed with the county clerk.
• Boundary survey. A survey by a licensed land surveyor that establishes or confirms the corners. Oklahoma's minimum standards require a monument at every corner. See how to read a survey and plat.
• Monument (pin). The physical marker at a corner, typically a capped metal rod stamped with the surveyor's licence number.
• Topo map. A map with contour lines showing elevation and slope. See how to read topo, flood and soil maps.

Ownership and deeds

• Deed. The signed document that transfers ownership of land.
• Warranty deed. A deed in which the seller guarantees the title. A general warranty deed covers the whole history of the title; a special warranty deed covers only the seller's period of ownership.
• Quitclaim deed. A deed that passes whatever interest the seller has, if any, with no guarantee. Normal between family members and to clear up title; a warning sign as the only deed offered in an arm's-length sale.
• Tax deed. A deed issued after a county sale for unpaid taxes. Title from a tax deed often needs a court action to be insurable.
• Recording. Filing a deed or other document with the county clerk. In Oklahoma, a recorded instrument gives constructive notice to later buyers, which is why unrecorded promises do not protect you.
• Surface rights. Ownership of the land surface, as distinct from the minerals beneath it.
• Mineral rights. Ownership of oil, gas and other minerals. In Oklahoma they are frequently owned separately from the surface. See mineral rights when buying land.
• Severed minerals. Minerals that were sold or reserved apart from the surface at some point in the past. A buyer of the surface does not get them.
• Surface Damages Act. The Oklahoma law requiring an oil and gas operator to give the surface owner written notice before drilling and to negotiate surface damages. It provides compensation; it does not give the surface owner a veto.
• Timber rights. The right to cut standing timber, which can be sold or reserved separately from the land. See timber rights and water rights.
• Heirs' property. Land that passed through one or more deaths without probate, leaving several relatives as co-owners. All of them must sign, or a court must sort it out.
• Transfer-on-death deed. An Oklahoma deed that names who receives the land at the owner's death. See passing land to family.

Access and neighbors

• Legal access. A recorded right to reach the tract from a public road. Not the same as being able to drive there. See legal access and easements.
• Deeded access. Legal access that is written into a recorded deed or easement.
• Easement. A right to use someone else's land for a stated purpose, such as a road or a power line, without owning it.
• Express easement. An easement created in writing and recorded. It normally runs with the land, binding later owners.
• Prescriptive easement. An easement claimed through long use without permission. In Oklahoma it requires 15 years of open, continuous, adverse use, and the claimant must prove it in court.
• Easement by necessity. A court-recognized access right for land that became landlocked when a larger tract was divided.
• Landlocked. Having no legal access to a public road.
• Right-of-way. The strip of land an easement or road occupies.
• Section-line road. In Oklahoma, section lines that have been opened and are maintained by the county or state are public highways. Not every section line has been opened.
• County road and private road. A county road is maintained by the county commissioners. A private road is maintained by its owners or a road association. See county roads vs private roads.
• Covenant (deed restriction). A recorded rule that limits how land may be used, for example on mobile homes, livestock or commercial use. Covenants bind later owners. See covenants and restrictions explained.
• Setback. A required distance between a structure and a boundary, road or water feature, set by covenant or regulation.

Title and closing

• Title. The legal right of ownership, and the chain of documents that proves it.
• Chain of title. The sequence of recorded transfers from the original owner to the present one.
• Abstract of title. A certified compilation of every recorded document affecting a tract. Oklahoma is unusual: under Insurance Department rules a title policy cannot be issued without an Oklahoma attorney's opinion based on a certified abstract from a licensed abstractor.
• Title commitment. The title company's written offer to insure, listing what must be cleared before closing and what will be excluded.
• Schedule B. The part of a title commitment listing requirements and exceptions, such as easements and mineral reservations. Read it before closing.
• Owner's title insurance. An optional policy that protects the buyer against claims on the title that predate the purchase.
• Lender's title insurance. A policy most lenders require, protecting the amount they lend. It does not protect the buyer.
• Quiet title. A lawsuit asking a court to settle who owns a tract.
• Closing. The meeting, or exchange of documents, at which money is paid and the deed is delivered.
• Documentary stamp tax. Oklahoma's tax on deeds when the consideration exceeds $100, at $0.75 for each $500 of consideration or fraction of it. On a $50,000 sale that is $75. See closing costs on Oklahoma land.

Taxes

• Ad valorem tax. Property tax, charged on value. In Oklahoma, tax equals fair cash value times the county assessment ratio times the millage rate. See property taxes on raw land.
• Fair cash value. The value the county assessor places on real property as of January 1 each year.
• Assessment ratio. The percentage of fair cash value that is taxed. Each Oklahoma county sets its own within the range the state constitution allows.
• Mill. One thousandth of a dollar: $1 of tax per $1,000 of assessed value. Millage is the total of the mills levied where the land sits.
• Use value. The value of agricultural land based on what it earns in farm use, which Oklahoma estimates by capitalizing cash rent, instead of on what it would sell for.
• Agricultural exemption. In Oklahoma this phrase is used for two different things: agricultural use valuation for property tax, and the Tax Commission's sales tax exemption permit for farm and ranch purchases. See the agricultural exemption on raw land.
• Homestead exemption. A reduction in assessed value for an owner's permanent residence. It does not apply to vacant land.

Water, septic and utilities

• Perc test. A percolation test measuring how fast water drains through soil. In Oklahoma it can be used only to design a conventional subsurface septic system.
• Soil profile. The test Oklahoma's Department of Environmental Quality relies on for most systems: at least three holes or pits examined by DEQ or a certified soil profiler to see which system types the soil allows. See perc tests and septic systems.
• Authorization to Construct (ATC). The DEQ approval you must obtain before installing or modifying an on-site sewage system.
• Conventional and aerobic systems. A conventional system uses a tank and buried lateral lines. An aerobic treatment unit treats wastewater mechanically and is used where soil is shallow or tight.
• Domestic use. Under Oklahoma water law, household use, watering farm and domestic animals up to the land's normal grazing capacity, and irrigating up to three acres of garden, orchard and lawn. Domestic use does not need a water-use permit from the Oklahoma Water Resources Board.
• Line extension. New electric line built from the nearest existing pole to your site. The electric cooperative estimates the cost. See utilities on rural land.
• Guaranteed utilities. A seller's promise about which utilities are available to a tract. See what "guaranteed utilities" means.

Flood and terrain

• FIRM. A FEMA Flood Insurance Rate Map, the official map of flood zones.
• Special Flood Hazard Area. The high-risk area on a flood map, shown as zones beginning with A or V.
• Base flood elevation. The height floodwater is expected to reach in the base flood. Zone AE has one published; Zone A does not. See flood zones, surveys and title insurance.

Money and financing

• Raw land. Land with no improvements. Federal bank guidelines set a supervisory loan-to-value limit of 65% for raw land. See raw land vs improved land.
• Improved property. For bank lending, completed property or farmland, ranchland or timberland in ongoing production, with a supervisory limit of 85%.
• Loan-to-value (LTV). The loan amount divided by the property's value. A 65% limit means at least 35% down.
• Owner financing (seller financing). The seller, not a bank, carries the loan. See how owner financing works.
• Contract for deed. A sale in which the buyer pays over time and the seller keeps the deed until the contract is paid. See contract for deed vs deed and mortgage.
• Mortgage and promissory note. The note is the promise to repay. The mortgage pledges the land as security for it.
• Balloon payment. A large one-time payment due at the end of a loan whose regular payments did not fully repay it.
• Property report. A federal disclosure document that developers of larger subdivisions covered by the Interstate Land Sales Full Disclosure Act must give buyers before they sign.

Frequently asked questions

What does metes and bounds mean?

It is a way of describing land by walking its boundary on paper. The description starts at a known point, called the point of beginning, then gives each boundary line as a direction and a distance until it returns to the start. It is used for tracts that do not follow the square grid of sections.

What does section, township and range mean on an Oklahoma deed?

They locate land on the public land survey grid. Townships are roughly six miles square, counted north or south of a base line; ranges are counted east or west of a meridian. Each township has 36 sections of about 640 acres. In Oklahoma outside the Panhandle, the reference is the Indian Meridian.

What is the difference between a plat and a survey?

A survey is the work a licensed surveyor does to locate boundaries on the ground. A plat is the drawing that results, showing tracts, dimensions, roads and easements. A recorded plat is one filed with the county clerk, which makes its tract numbers usable in legal descriptions.

What does perc mean when buying land?

It is short for percolation test, a measure of how fast water drains through soil, used to judge whether a septic system will work. In Oklahoma a perc test can be used only for a conventional subsurface system. The Department of Environmental Quality's soil profile test is used for the other system types.

What is an easement on land?

An easement is a right to use part of someone else's land for a specific purpose without owning it. The most common are access easements, which let one owner cross another's land to reach a road, and utility easements for power or water lines. A recorded easement normally stays with the land when it is sold.

What is the difference between a warranty deed and a quitclaim deed?

A warranty deed includes the seller's guarantee that the title is good. A quitclaim deed transfers only whatever interest the seller happens to have and guarantees nothing. Quitclaim deeds are normal for family transfers and title clean-up. In a sale between strangers, expect a warranty deed and title insurance.
