How to read a land survey — a landowner's guide.

The short answer

A land survey is a licensed surveyor's precise map of what you own: where the boundaries run, where the corners sit, and what rights of way cross the parcel. Reading one comes down to four things — the title block (who surveyed what, and when), the north arrow and scale, the boundary "calls" (a bearing and a distance for each property line), and the monuments (the physical markers a surveyor set at your corners). Dashed lines and labels usually mark easements — the part sellers most often overlook.

If you're selling, here's the answer to the question behind the question: you usually don't need to commission a new survey just to sell rural land. Your deed's legal description is what transfers ownership. A fresh survey earns its cost when boundaries are genuinely in doubt, when you're dividing a parcel, or when a buyer's lender requires one — and who pays for it is negotiable, not a law.

Start here

What a land survey actually shows.

A survey plat is a bird’s-eye drawing of your parcel, produced by a licensed surveyor who measured it on the ground. Three pieces orient you before any of the technical detail matters:

The title block — usually a corner of the drawing — names the surveyor, the date, the parish or county, and the property surveyed. The date matters more than people expect: a survey is a snapshot, and a plat from 1987 doesn’t show the pipeline servitude granted in 2005.

The north arrow and scale tell you how the drawing sits on the earth and how to translate inches on paper into feet on the ground.

The legend decodes the symbols — which line style means a boundary, which means an easement, what the little circles and squares at the corners represent. Every surveyor draws slightly differently; the legend is the decoder ring.

The boundary

How to read the property lines — bearings, distances, and calls.

Each straight run of your boundary is written as a call: a bearing plus a distance. “S 89°47’W, 660.00’” is a line running just south of due west for 660 feet. Start at the corner the plat labels the point of beginning and follow the calls in order — they walk the boundary all the way around and close back where they started, which is how the legal description in your deed describes the same parcel in words.

You don’t need to verify the geometry — that’s the surveyor’s license on the line. What you’re reading for is the shape and the neighbors: does the drawing match the land you know, the fence lines you’ve maintained, the road frontage you believe you have? Where the paper and your understanding disagree, that disagreement is exactly the thing to resolve before a buyer finds it.

On the ground

Where your corners actually are — monuments and markers.

The corners on the drawing correspond to physical monuments the surveyor found or set: iron rods, pipes, concrete markers, occasionally an old axle or a blazed tree noted from a century-old survey. Newer pins usually carry a plastic cap stamped with the surveyor’s license number.

Knowing where even two or three corners sit transforms a sale. Buyers of rural land ask “where are the lines?” before almost anything else, and an owner who can walk to a capped pin answers a question that otherwise costs a showing. Flagging tape on the monuments you can find is the cheapest marketing a wooded parcel gets.

The fine print

Easements, encroachments, and the notes that matter in a sale.

The boundary is rarely where survey surprises live. The dashed lines are:

Easements and rights of way — utility lines, access roads, drainage, pipelines — drawn as dashed or dotted lines with a label like “30’ utility servitude.” (Louisiana law calls them servitudes; same idea.) These survive a sale and pass to the buyer, so they belong in the conversation early. Our guide to easements covers how each kind affects a sale.

Encroachments — the neighbor’s fence eight feet inside your line, a shed over the boundary, a driveway that wanders. Surveyors draw what exists, and an encroachment on a plat is a title conversation waiting to happen. Better to have it now than at a closing table; our guide to clearing title problems explains the usual fixes.

Notes and references — flood-zone panels, setback lines inside municipalities, references to the prior surveys the boundary was built from. Flood designation especially is worth confirming independently on FEMA’s public map; it moves value in coastal parishes and counties more than zoning does.

The seller's question

Do you need a new survey to sell?

Usually, no — and it’s worth saying plainly, because commissioning an unnecessary survey is one of the more common ways sellers spend money they didn’t need to spend. Ownership transfers by the legal description in your deed. If the parcel’s boundaries aren’t in dispute and you’re selling the whole tract as-is, the existing description and records generally carry the sale.

A new survey earns its cost in three situations: the boundaries are genuinely uncertain or contested; you’re dividing a tract, which requires a new plat by definition; or the buyer’s lender requires one, which is common with financed purchases and construction loans. Even then, who pays is a term of the purchase agreement — negotiate it, don’t assume it.

When we buy land, we work from the deed, the parish or county records, and the plats already on file. A survey isn’t a hoop we make sellers jump through.

If there's no survey at all

No plat in the family papers? Here’s where to look.

Most rural parcels have more paper trail than their owners think:

Your deed holds the legal description — sometimes referencing a recorded plat by book and page, which the clerk’s office can pull.

The parish clerk of court (Louisiana) or chancery clerk (Mississippi) holds the recorded plats and conveyance records for every parcel in the parish or county. A morning at the counter — or increasingly, their online portal — often turns up a plat the family never knew existed.

The assessor’s or tax map shows your parcel’s shape and neighbors. It’s a tax document, not a boundary authority, but it’s a fine orientation tool and it’s free.

If those come up empty and the sale genuinely needs one, hire a licensed surveyor working in your parish or county — local surveyors know the local records, and rural boundary work leans on them heavily. For what the land might bring once the lines are settled, start with what your land is actually worth.

Questions & answers

Asked by nearly every family we work with.

What do the bearings and numbers on my survey mean?

Each boundary line is written as a bearing and a distance — "N 45°12'E, 300.00 feet" means the line runs 300 feet in a direction 45 degrees east of north. Follow the calls in order and they trace your boundary all the way around, back to the point of beginning. You don't need to do the math — you need to confirm the picture matches what you believe you own.

How do I find my property corners on the ground?

Start at a corner the survey shows relative to something findable — a road intersection or a fence line — and look for the monument the plat describes, usually an iron rod or pipe, sometimes with a plastic cap carrying the surveyor's license number. A metal detector helps; decades of leaf litter hide most pins. If corners truly can't be found, that's a surveyor's job, not a guessing game.

How much does a land survey cost?

It depends on acreage, terrain, and how good the existing records are — thick woods and thin records cost more than open pasture with a recent plat next door. Get quotes from two licensed surveyors working in your parish or county. And before spending anything, ask whether the sale you have in mind actually requires one — ours usually don't.

Do I need a survey to sell my land?

Usually not. Ownership transfers by the legal description in your deed, and for most rural sales the existing records are enough. A new survey becomes worth it when boundaries are disputed, when you're selling part of a larger tract, or when the buyer's lender demands one. When we buy, we work from the deed and parish or county records — commissioning a survey isn't a cost we push onto the seller.
