Order the survey that answers your decision
Define a useful survey scope and reconcile legal descriptions, monuments and visible occupation.
Landosaur research · Updated 2026-10-01A survey should resolve a defined problem: locating a boundary, understanding occupation, planning a driveway, placing improvements or meeting a transaction requirement. Asking only for “a survey” can produce a deliverable that is technically useful but incomplete for your decision. Describe the intended use and agree on the scope before work begins.
Assemble the record package
Provide the surveyor with the purchase documents, legal description, title materials, existing surveys, recorded plats and relevant easements. Identify every parcel included in the offering. Tell the surveyor about visible fences, roads, structures or disputes that may matter, without assuming those features establish the boundary.
BLM’s acquisition guidance explains the relationship between physical boundaries and written land descriptions, and how survey review can identify conflicts or ambiguity. It governs BLM work rather than private survey practice, but it illustrates why a legal description and a map image need reconciliation. BLM land-acquisition survey guidance.
Choose the required deliverable
Discuss boundary evidence, corner marking, acreage, improvements, encroachments and easement locations as applicable. If you need topography, construction staking or a particular lender or title-insurer format, state that explicitly. Those requirements may involve different work from locating the outer boundary.
Ask what the surveyor will research, what will be observed in the field, what will appear on the drawing and what will remain outside the assignment. Confirm who receives and may rely on the finished product. Obtain timing, access arrangements and an explanation of conditions that could expand the scope.
BLM’s cadastral tools make survey records and Public Land Survey System resources easier to locate. Such references can inform the investigation, but copying a public grid onto an aerial image does not establish a new private boundary survey. BLM cadastral tools.
A hypothetical boundary issue
Suppose a listing shows a fence as the west boundary. A driveway and proposed house location were selected using that image. The survey identifies a different record line and explains that the fence lies inside the parcel. That may create more space, but it may also reveal occupation or access questions requiring legal review.
The surveyor’s findings should prompt a coordinated response. Ask the title professional and attorney what documents or agreements are needed, then have the designer update the layout. Do not move a fence, remove a monument or confront a neighbor based solely on an initial interpretation.
Read the finished work actively
- Match the legal description and parcel set to the intended purchase.
- Identify the date, measurement basis, legend and surveyor’s qualifications.
- Read notes about found evidence, unresolved discrepancies and limitations.
- Confirm whether relevant easements and visible improvements are shown.
- Ask which findings change your site plan, title review or cost assumptions.
Use services to specify the survey assignment and store the final deliverable with the transaction record. Transfer any resulting layout or cost changes into analysis. The value of the work is a better-supported decision about the actual property—not merely a more precise-looking outline on a map.
