A boundary survey does more than draw lines on a map. It tells you exactly what you are buying. Yet most buyers walk into a purchase without asking the right questions. They assume the deed matches the ground. They assume old fences sit on the actual boundary. They assume there are no complications.
Those assumptions can be expensive.
Here are the questions worth asking before you close.
Does the Deed Match What Has Been Used on the Ground for Years?
A property’s legal description and the way it has actually been used do not always agree.
Driveways, sheds, garden beds, and old fences often get built without checking the exact boundary first. Over time, those features become the de facto boundary in the minds of neighbors. But the deed says something different.
When a boundary survey is completed, it measures the legal description. If a neighbor’s shed sits two feet over the line, the survey will show it. If a shared driveway crosses your parcel, the survey will show that too.
Ask your surveyor: Does the boundary match how the property has been used? If there are differences, what are the options?
Understanding the gap between the deed and actual use before closing gives you time to sort it out. Waiting until after closing makes it your problem alone.
Are There Older Survey Markers or Records That Could Affect the Findings?
Colorado has been surveyed in layers. Government surveyors mapped the land in the 1800s. Local counties recorded plats as towns were platted. Private surveyors have re-established corners many times since.
All of that history matters.
When a surveyor researches your property, they dig through those older records. They look for original monuments, recorded plats, deed calls, and previous surveys. If they find a 100-year-old iron pin in the ground, it carries legal weight. If two surveys disagree, the surveyor has to decide which evidence is more reliable.
Ask your surveyor: Were older monuments or records found? How did they affect the boundary location?
This is not a minor detail. In areas with long ownership histories or disputed corners, older evidence can shift a boundary by several feet. Knowing how your surveyor resolved that evidence tells you how solid the final result is.
What Nearby Features Could Make the Survey More Complex?
Not every parcel is a flat rectangle in a suburban subdivision. Colorado properties come with terrain, water, and irregular shapes that add complexity.
Common factors that can make a boundary survey more involved:
- Mountain terrain. Steep slopes and dense timber make fieldwork slower and more physically demanding.
- Creeks and streams. Water boundaries can change over time and involve different legal rules.
- Irregular lot shapes. Older subdivisions and rural parcels often have unusual shapes with many course changes.
- Shared access roads. A road shared by multiple owners may cross several parcels and require additional research.
- Missing monuments. If original corner markers are gone, the surveyor has to reconstruct the boundary from other evidence.
Ask your surveyor: Are there any conditions on or near this property that could affect the research or fieldwork?
A straightforward parcel in a modern subdivision is one thing. A mountain lot with a creek, a shared road, and a 19th-century deed description is another. Knowing the complexity upfront helps you set realistic expectations on cost and timeline.
Will the Survey Create New Monuments or Locate Existing Ones?
After the fieldwork is done, what physical evidence will remain?
That depends on what the surveyor finds and what type of survey is ordered.
In some cases, original corner monuments are still in the ground and in good condition. The surveyor locates them, verifies their position, and references them in the survey. No new markers are needed.
In other cases, monuments are missing, damaged, or in the wrong location. The surveyor sets new ones, typically iron pins or rebar with caps stamped with the surveyor’s license number.
Ask your surveyor: Will new monuments be set? Where will they be located?
This matters for practical reasons. Knowing where your corners are helps you build fences in the right place, locate utilities, and communicate with contractors. A survey with physical monuments on the ground is more useful than a map alone.
Who May Need a Copy of the Boundary Survey After Closing?
Once the survey is done and you close, the document does not just sit in a file forever unused.
Several parties may need it later:
- Lenders. Some refinancing situations require updated survey documentation.
- Title companies. A boundary survey can resolve questions about encroachments or easements that affect title insurance.
- Attorneys. Boundary disputes and easement negotiations require accurate survey data.
- Architects and engineers. Site design, setback calculations, and drainage planning all start with a survey.
- Contractors. Knowing exact boundary locations prevents costly mistakes during construction or grading.
- Future buyers. A clean, well-documented survey history makes your property easier to sell and insure.
Ask your surveyor: Will a digital copy of the survey be provided? Is it recorded with the county?
Keep physical and digital copies organized. A boundary survey is a legal document. Treating it like one saves headaches down the road.
Frequently Asked Questions
Why should buyers ask about older surveys?
Older surveys and monuments may provide valuable evidence that helps establish the correct property boundaries. Ignoring that history can lead to a boundary location that does not hold up under scrutiny.
Can a boundary survey reveal differences between the deed and actual property use?
Yes. Features that have been used for years may not always line up with the legal description. A survey shows both what the deed says and what is actually on the ground.
Will a surveyor always set new corner markers?
Not always. Existing monuments may already provide sufficient evidence. Some situations require new markers to be placed when originals are missing or cannot be verified.
Why are some boundary surveys more difficult than others?
Terrain, irregular parcels, missing monuments, and historic records can make research and fieldwork more complex. Mountain properties and older subdivisions in Colorado often involve more variables than standard suburban lots.
Who should keep a copy of the completed boundary survey?
Property owners should keep it. Copies may also be useful for title companies, lenders, architects, contractors, and future buyers. Storing both physical and digital versions is a good practice.
