Indiana Land Surveying Law: The Basics
Indiana regulates professional land surveying under Indiana Code IC 25-21.5. This statute defines who may practice land surveying, what constitutes the practice, and the legal consequences of unlicensed work. The Indiana Professional Licensing Agency (IPLA) administers licensing, and the Indiana State Board of Registration for Land Surveyors sets professional standards and handles disciplinary matters.
Any person who performs boundary surveys, sets monuments, prepares legal descriptions for recording, or subdivides land in Indiana must hold an active Professional Land Surveyor (PLS) license from the IPLA. Practicing without a license is a violation of IC 25-21.5 and can result in civil penalties and injunctive action by the state.
Indiana PLS Licensing Requirements Under IC 25-21.5
To earn a PLS license in Indiana, candidates must meet the following requirements under IC 25-21.5 and IPLA rules:
- Earn an accredited degree in land surveying, surveying technology, or a related engineering or science field (or meet alternative education criteria)
- Complete four years of qualifying experience in land surveying practice under the supervision of a licensed PLS
- Pass the NCEES Fundamentals of Surveying (FS) exam
- Pass the NCEES Principles and Practice of Surveying (PS) exam
- Submit a complete application to the IPLA with verified experience references
PLS licenses must be renewed on IPLA's schedule with documented continuing education. You can verify any Indiana PLS license at pla.in.gov.
Survey Monuments and Indiana Property Corners
Survey monuments are the physical markers that establish the legal evidence of property corners in the field. In Indiana, acceptable monuments include iron pins, iron pipes, concrete monuments, and drill holes in bedrock. When a licensed PLS performs a boundary survey and finds that a corner monument is missing or has been disturbed, they are required to set a new monument at the correct position and document it in the survey record.
Tampering with survey monuments is a serious matter in Indiana and across all states. Property corners serve as the foundation of the entire chain of property ownership in an area. Removing or disturbing a corner monument, even accidentally during construction or landscaping, can create significant legal complications for the property owner and neighbors. If you discover a monument has been disturbed, contact a licensed Indiana PLS to evaluate and restore the corner.
Plat Recording Requirements Under IC 36-7-4
When land in Indiana is divided into lots or parcels, the process is governed by Indiana Code IC 36-7-4, which establishes requirements for subdivision plats and their review and recording. Key points Indiana property owners need to understand:
- Any division of land into two or more lots generally requires a plat prepared by a licensed Indiana PLS
- The plat must be reviewed by the local plan commission or county planning department
- After approval, the plat must be recorded with the county recorder
- Once recorded, the plat becomes the controlling legal document for boundary descriptions in the subdivision
- Failure to properly record a plat can create title defects that affect future sales and financing
Minor Land Divisions (also called administrative subdivisions or lot splits) may follow a simplified process in some Indiana counties, but a licensed PLS is still required to prepare the legal descriptions and boundary drawings.
Property Line Disputes in Indiana
Property line disputes between Indiana landowners arise in several common situations: fence placement near shared boundaries, encroachments by buildings or improvements, disagreements about easement locations, and questions about deed description accuracy.
How Disputes Are Resolved
When neighbors disagree about the location of a property line in Indiana, a boundary survey by a licensed PLS is the first step toward resolution. The surveyor researches historical deeds, plats, and field evidence, then prepares a plat showing the legal boundary position. This plat is the evidentiary foundation for any negotiated settlement or court proceeding.
Indiana courts routinely rely on licensed PLS surveys in property line litigation. A survey performed by a licensed Indiana PLS carries legal weight; an estimate by an unlicensed person does not. If a dispute escalates to litigation, Indiana courts apply principles of deed construction, acquiescence, adverse possession, and practical location to determine the controlling boundary.
Adverse Possession in Indiana
Indiana recognizes adverse possession as a legal doctrine by which a person who has openly and continuously used land for the statutory period (10 years in Indiana under IC 32-21-7) may acquire title to it. This doctrine creates situations where a fence line that has been in place for many years may have legal significance beyond its physical location. A licensed PLS cannot render a legal opinion on adverse possession, but their survey documents the current facts that an attorney can then analyze under Indiana law.
Easements and Survey Evidence
Easements give one party the right to use another party's land for a specific purpose. Common easements in Indiana include utility easements, drainage easements, ingress/egress easements, and pipeline easements. Survey plats show the location and dimensions of easements of record as they affect the property.
When purchasing Indiana property, a title commitment will list known easements of record. However, easements created by use or prescription may not appear in the title records. A licensed PLS conducting a boundary survey can identify evidence of physical use patterns and improvements that may indicate easements by prescription or implication, which can then be evaluated by a title attorney.
Why Survey Work Must Be Done by a Licensed PLS
Indiana Code IC 25-21.5 makes the reason clear: land surveying decisions affect property rights, legal title, construction safety, and municipal planning. Errors in surveys can result in structures being built on the wrong land, fences creating trespass situations, subdivisions with unmarketable title, and legal disputes that take years to resolve.
The licensing system protects Indiana property owners by requiring surveyors to demonstrate competence through education, experience, and examination before they can legally practice. When you hire a licensed Indiana PLS, you have a direct legal remedy if the work is deficient. A licensed surveyor carries professional liability insurance and is subject to disciplinary action by the IPLA for negligent or improper practice.
When Indiana Property Owners Should Hire a Licensed PLS
Consider hiring a licensed Indiana PLS in any of these situations:
| Situation | Why a Survey Matters |
|---|---|
| Building permit application | Municipality requires site plan showing setbacks from property lines |
| Installing a fence along a shared boundary | Confirms line location before investment in fence materials |
| Buying rural or vacant land | Confirms actual acreage and boundary location before purchase |
| Selling property with unclear boundaries | Avoids buyer objections and title insurance exceptions |
| Neighbor encroachment concern | Establishes legal boundary position for negotiation or litigation |
| Dividing or subdividing land | Required by IC 36-7-4 for recorded plat |
| Flood insurance or LOMA application | Elevation certificate required by FEMA and NFIP |
