The statute defines the work, not a list of project names
RSMo 327.272 defines professional land surveying by the judgment involved. It includes determining or retracing real-property boundaries and United States Public Land Survey System positions, monumenting corners, subdividing land, preparing property descriptions, locating easements and rights-of-way, and preparing boundary drawings.
For a homeowner, the line is practical. Looking up a parcel, reading a deed, or measuring for preliminary planning is research. RSMo 327.272 places boundary determination, corner monumentation, and property descriptions within a Missouri professional land surveyor's work.
Missouri's PLSS and survey repository change the records search
The Missouri Land Survey Program maintains public-land corner information and a statewide repository of about two million digitized survey documents. That record system can matter more to a boundary retracement than a current tax map, particularly for rural land described by section, township, and range.
Missouri also removes ambiguity about cadastral maps. 2 CSR 90-65.080 requires a warning that these maps are informational and cannot be used for conveyance or establishing property boundaries.
Three rules to address in the estimate
| Rule | What to ask |
|---|---|
| Professional scope | Who is the Missouri PLS in responsible charge and what will be signed or sealed? |
| Survey records | Will the firm search the Land Survey Index, county records, and relevant corner documents? |
| Necessary access | Will adjoining land need to be entered, and how will notice and property protection be handled? |
RSMo 327.371 gives a professional land surveyor a limited trespass exemption when entry is necessary to make a survey and makes the surveyor liable for actual damage. It does not give a homeowner permission to enter a neighbor's property or resolve a dispute.
Use the law to choose the right deliverable
For a fence, ask whether the boundary and the construction side will be staked. For a deed split, ask what description, plat, county review, and recording work are included. For a neighbor conflict, request a survey focused on the disputed line and keep ownership-law questions for an attorney.
Verify before hiring
Check the person and firm through the Missouri board's online search. A current license is a threshold check, not a guarantee of price, schedule, or fit. Use the Missouri land surveyor directory to locate firms, then compare written scopes.
