A soybean field looks the same from the road whether it hides three boundary disputes or none. Rural land rarely gives away its secrets on a drive-by. Underground tile lines, split mineral rights, and old handshake easements don’t show up in a listing photo. They tend to show up later, often after the papers are signed.
An ALTA survey digs into that hidden layer before you close. It pairs careful fieldwork with a review of title records, so buyers see what a basic boundary check misses. Here’s what that process can turn up on farmland and rural acreage specifically.
Buried Drainage Tile Lines You Can’t See From the Road
Most farmland relies on drainage tile to keep fields workable. These clay or plastic pipes sit a few feet underground and carry water off the property, often crossing into a neighbor’s land too.
A basic boundary survey won’t map this system. It only marks corners and lines.
An ALTA survey can include tile mapping as an optional item under Table A. That means the surveyor locates and documents these lines before you buy.
This matters for a few reasons. Damaged or aging tile can flood a field for a season. Shared tile lines may come with maintenance responsibilities you didn’t know about. And if a past owner rerouted a line without permission, that’s a problem you don’t want to inherit.
Ask your surveyor to include tile locations in the survey scope. It’s a small request that can save a full growing season.
Split Mineral, Oil, and Gas Rights Hiding in the Title
Farmland has a long history in most parts of the country. Somewhere in that history, a past owner may have sold off the mineral rights and kept the surface.
That means someone else could legally hold rights to the oil, gas, or minerals under your field, separate from your ownership of the ground on top.
An ALTA survey alone won’t tell you this. But the title commitment review that comes with the ALTA process often will. Surveyors check recorded documents against what they find in the field, and severed mineral rights tend to surface during that process.
If minerals were split off, you’ll want to know before closing. Not after a drilling crew shows up with paperwork you’ve never seen.
Wetland and CRP Boundary Conflicts That Limit What You Can Farm
Government conservation programs often protect specific acres within a larger parcel. Conservation Reserve Program (CRP) land and designated wetlands come with rules about what you can plant, build, or clear.
The problem is these boundaries rarely match the property line or the fence row. A field might look like one solid block of tillable ground, but part of it could sit inside a protected zone.
An ALTA survey can show where these boundaries actually fall on the ground, not just on a program map. That helps you understand how much of the acreage is truly usable for row crops or grazing.
Before closing, confirm current program status directly with USDA or your local NRCS office. The survey shows where the lines sit. The agency confirms what those lines mean for your farming plans.
Landlocked Parcels and Undocumented Access Roads
Rural tracts don’t always sit next to a public road. Some rely on a gravel lane that crosses a neighbor’s property, based on years of quiet, informal use rather than a recorded legal right.
That kind of access can work fine for decades. Right up until the neighbor sells, changes their mind, or passes the land to someone who doesn’t honor the old arrangement.
An ALTA survey checks whether your access is backed by a recorded easement or just tradition. This detail matters more than it seems. Lenders often require proof of legal access before approving a loan. Future buyers will ask about it too.
If the survey turns up a gap here, talk to a real estate attorney about securing a written easement before you close.
Old Fence Lines That Don’t Match the Legal Boundary
Fences on farmland get built for convenience, not precision. A landowner decades ago may have run a fence a few feet off the true line to avoid a rock outcrop or a soft patch of ground.
Over time, everyone treats that fence as the boundary. Crops get planted up to it. Cattle graze inside it. Then a new survey shows the real line sits somewhere else.
An ALTA survey compares the legal description in the deed against what’s actually built on the ground. Any gap between the fence and the recorded boundary shows up clearly.
Catching this before closing gives you room to work it out with the neighboring landowner while everyone’s still on good terms. Waiting until after closing turns a simple conversation into a dispute.
Knowing what sits under a piece of farmland, and what its legal boundaries actually are, puts you in a stronger position at the closing table.
FAQ
Does an ALTA survey show underground tile drainage on farmland?
Only if you request that item. A standard boundary survey typically won’t include it.
Can an ALTA survey reveal if mineral rights were sold separately from the land?
The survey maps physical features. The title review required under ALTA standards often turns up severed mineral rights before closing.
Will an ALTA survey flag wetland or CRP restrictions on the acreage?
It can show where these boundaries fall on the ground. Confirm current program status directly with USDA or your local NRCS office as well.
Is an ALTA survey worth it for bare farmland, or just farms with buildings?
Yes, even without buildings. Access, easement, and boundary risks exist whether or not structures sit on the land.
How does an ALTA survey differ from a standard rural boundary survey?
It adds a title document review and optional items like utility mapping and access confirmation, on top of standard boundary work.
How long does an ALTA survey take on larger rural tracts compared to a city lot?
Usually longer. Rural acreage covers more ground, has fewer visible monuments, and often requires tracing old easements or tile records.
