Most property owners get a deed and a plat of survey at closing and treat them as the same thing. They’re not. One is a legal ownership document. The other is a scaled map. They serve different purposes, and mixing them up leads to real problems when permits, disputes, or construction plans come into play.

What a Deed Actually Contains

A deed transfers ownership. That’s its job.

It identifies the parties involved, states that ownership is being transferred, and includes a legal description of the property. That legal description uses bearings, distances, and reference points to define the parcel in words. It might also reference an easement or two by recorded instrument number.

What a deed does not contain: a drawing, any visual representation of the lot, the location of improvements, setback lines, or physical measurements you can use in the field.

The legal description in a deed tells you what you own in legal terms. It does not show you what your property looks like on the ground.

What a Plat of Survey Shows

A plat of survey is a scaled drawing produced by a licensed surveyor. It shows the physical reality of the parcel, not just the legal description.

The plat includes the lot dimensions with measured distances on every boundary line. It shows the shape of the parcel to scale. It locates all improvements on the property: the house, any outbuildings, driveways, fences, and other structures. It shows where those improvements sit relative to the boundary lines, often with exact measurements to the nearest foot or tenth of a foot.

That’s information a deed can never give you. A deed says you own a parcel described as “commencing at the northeast corner.” A plat shows you exactly where that corner is, what the lot looks like, and how close your garage sits to the side property line.

What Else Appears on a Plat of Survey

Beyond lot dimensions and improvement locations, a plat of survey typically shows:

• Easement lines and their widths, drawn to scale on the map
• Setback lines as required by local zoning
• Encroachments, where a structure crosses a boundary or easement line
• Flood zone notations if the parcel falls within or near a mapped flood area
• The surveyor’s certification, seal, license number and survey date
• Any gaps or overlaps between the parcel and adjacent properties

A deed might reference an easement by recorded book and page number. The plat draws it on the map so you can see exactly where it falls on the lot and how much buildable area it removes.

Why Developers Need Both Documents

A deed alone can’t answer site planning questions. A plat of survey can.

If you want to know whether a proposed building footprint fits inside the setbacks, you look at the plat. If you want to confirm whether an existing structure encroaches onto a neighboring parcel, you look at the plat. If your engineer needs the lot dimensions to begin a site plan, they need the plat.

The deed handles the ownership side. The plat handles the physical side. You need both to have a complete picture of any parcel.

When the Two Documents Conflict

Sometimes a plat of survey and a deed don’t agree. The legal description in the deed might reference a boundary that doesn’t match what the surveyor found in the field. This happens more often than people expect, especially on older properties with surveys that predate modern GPS equipment.

When conflicts arise, the plat produced by a licensed surveyor using current field measurements carries more weight for practical purposes. Courts and title companies look at both, but physical evidence on the ground, tied to a properly sealed survey, generally controls over a legal description that hasn’t been verified by field work.

If you spot a conflict between your deed description and your plat of survey, don’t ignore it. It can affect title insurance, permit approvals, and your ability to close on a sale.

What Happens When You Only Have a Deed

Developers who try to plan a project using only the deed run into the same problems repeatedly.

They can’t confirm setbacks without a drawn survey. They can’t verify whether improvements are within the lot lines. Their architect or engineer has no scaled base to work from. If a question comes up about an easement, they have a book and page reference but no visual showing where it sits on the property.

A deed is a starting point. A plat of survey is the working document.

If you’ve closed on a property and only received a deed, ask your title company whether a plat was recorded. Many properties in recorded subdivisions have a subdivision plat on file with the county. That plat shows the original lot layout. But it won’t show current improvements, recent encroachments, or conditions that have changed since the subdivision was recorded.

For current conditions, you need a survey ordered specifically for your parcel, done by a licensed surveyor, and sealed with a current date.

Frequently Asked Questions

Can I use a deed to determine my property lines? 

A deed contains a legal description that defines the property in words and measurements, but it doesn’t show you where those lines fall physically on the ground. To see property lines drawn to scale with physical measurements, you need a plat of survey produced by a licensed surveyor.

What is the difference between a subdivision plat and a plat of survey? 

A subdivision plat is a recorded map of an entire subdivision showing how a large parcel was divided into individual lots. A plat of survey is a survey of a single parcel that shows current conditions: improvements, easements, encroachments and setbacks as they exist today. Subdivision plats show the original layout. A plat of survey shows what’s there now.

Do I need a new plat of survey if I already have an old one? 

If conditions on the property have changed since the last survey, such as new structures, fences, additions or neighboring improvements, you should order a new survey. Lenders and title companies often require a survey dated within a specific period. An outdated plat may not reflect current encroachments or easement conditions.

Can a plat of survey be used in a property dispute? 

Yes. A plat of survey produced by a licensed surveyor and properly sealed is accepted as legal evidence in boundary disputes, easement conflicts and encroachment claims. Courts rely on survey data tied to physical monuments in the field when resolving property line disagreements.

Who legally needs a plat of survey? 

Lenders often require one at closing to confirm the property matches the legal description. Building departments require a survey as part of permit submittals. Title companies use it to identify issues before issuing title insurance. Any developer planning to build, subdivide, or sell should have a current plat of survey on file before the project moves forward.
