How old can a survey be and still be used?
No Virginia statute or regulation puts an expiration date on a survey. The date beside the surveyor's seal is not an end date for the survey. Whether an older boundary survey still serves depends on who is relying on it, such as a lender, a title insurer or a buyer, and on what has changed on the ground and in the land records since that date.
The date beside the seal is not a deadline
A boundary survey plat made under Virginia's survey standard carries the surveyor's seal, signature and date, and that date is the first thing anyone looking at an old survey reads. No Virginia rule turns it into an expiration date. The useful question is what has happened to the land, and to the records about it, since the day it was signed.
Minimum standards for land boundary surveys in Virginia are set by 18VAC10-20-370, most recently amended effective May 1, 2026. Under that regulation, the professional's seal, signature and date are evidence that the survey is "correct to the best of the professional's knowledge, information, and belief" and that it complies with the regulation's minimum standards and procedures. The date fixes when that statement was made. It says nothing about how long the statement stays true.
One number does circulate as a survey's shelf life, and it belongs to something else. Va. Code 15.2-2261 keeps an approved, recorded final subdivision plat valid for not less than five years from approval. That is about a locality's approval of a division, set out on the page about plats and parcel numbers in the record, not about the age of a survey.
An older plat states its own limits, if you read the notes
Before anyone decides an old survey is too old, the plat itself answers several questions, because the standard requires it to say what kind of work it rests on.
- Field survey or compilation. The plat must state whether it rests on a current field survey or on a compilation from deeds, plats or surveys by others. A compilation may not be titled a land boundary survey.
- Title report. The plat must state whether a current title report was furnished to the surveyor. The surveyor searches the land records for the description of the land and of the adjoining land along the common lines, but the regulation does not require the surveyor to research title or encumbrances.
- Easements and improvements. The plat must state whether easements and physical improvements are shown on it.
Those notes are dated too, which is the point. Adjoining owners named on an older plat may have sold since, and an easement recorded after the survey cannot appear on it. The document may also be a different kind of survey altogether. A survey that locates physical improvements on a parcel under two acres follows a separate standard from a boundary survey. How the field work and the plat are produced is covered in how a land survey works.
The lender, the title insurer or the buyer sets the bar, not the state
Because no statute retires a survey, whether an older one is accepted is a decision made by whoever is relying on it, for their own reasons, in the transaction at hand.
The loan conditions
A lender that wants survey coverage says what it will accept. The lender's own requirement is the answer, and the settlement agent or the lender is the one to ask.The policy exceptions
Whether an older survey is enough for the insurer behind a policy of title insurance on land is that insurer's decision, asked through the settlement agent. A policy does not cover losses listed in its exclusions and exceptions.Due diligence
On residential property the disclosure statement says the owner makes no representation about current lot lines, and it advises purchasers to use whatever due diligence they deem necessary, including obtaining a property survey.None of those decisions is made by the county map. Carroll County's Web GIS says its layers are for general reference only. A parcel outline on a county viewer may be more recent than an old plat, and it still does not do a survey's work.
Fences, divisions and new records: when an old survey stops matching
An old survey tends to fall short for one of three reasons: something was built, something was divided, or something was recorded.
Something built is the easiest to see on the ground. A neighbor's new fence or an outbuilding near the line can create an encroachment that a survey dated before it cannot show. On a parcel under two acres, the physical improvements standard has the surveyor locate in the field fences near the lines, cemeteries known, disclosed or discovered during the survey, and roads crossing the property that serve other properties, and locating physical improvements is part of the practice of land surveying under Va. Code 54.1-400.
Something divided changes the question. Carving a lot out of a surveyed tract is not answered by the old plat at all, and whether that needs new work is taken up in whether you need a new survey to subdivide. Something recorded, such as a later deed with a description that no longer lines up with the plat, is its own problem, worked through in what happens when the survey and the deed disagree.
For an owner getting ready to list, an older plat in the file is useful paper. Its date, its notes and its recording references tell a buyer's side where to start, and whether a survey is needed before listing at all is answered on the page about selling land in Southwest Virginia.

Questions this raises
What does it mean when an old plat says no title report was furnished?
It means no current title report was furnished to the surveyor for that plat, and the standard requires the plat to say whether one was. The plat still speaks to lines and monuments. What is recorded against the land, such as an easement created by a separate instrument, is found by a title search, and anything recorded after the plat's date could not appear on it in any case.
Is a house location survey the same thing as a boundary survey?
No. Virginia's surveying regulations set a separate standard for surveys that locate physical improvements on parcels or lots under two acres. That plat carries its own caption, including the date of survey, and where the surveyor finds discrepancies that, in the surveyor's opinion, warrant a land boundary survey, the client must be told one is deemed warranted as a requisite to completing the physical improvements survey.
