Can I Sell Land With a Drainage Tile Easement or Agreement With a Neighbor?
Key Takeaways
- NRCS sets the physical baseline for what's actually in the ground. Conservation Practice Standard 606, Subsurface Drain, requires a minimum 3-inch pipe diameter and at least 2 feet of soil cover in mineral soils — the specs behind most tile a seller will ever encounter, and a starting point for figuring out what condition an old system is likely in.
- Michigan is the one state in Jerez Land's footprint with a full statutory drainage system. Under the Drain Code of 1956 (MCL 280.1 et seq.), a county drain commissioner administers "county drains," and the cost of maintaining one can be levied as a special assessment that shows up directly on the property's tax bill.
- The nine states Jerez Land buys in don't share one surface-water drainage rule. North Carolina shifted from the civil law rule to the reasonable use rule in 1977; South Carolina applies a modified common enemy rule; Alabama, Georgia, Michigan, Pennsylvania, and Tennessee each apply their own version of a natural-flow-based approach — details and sources in the table below.
Can I Sell Land With a Drainage Tile Easement or Agreement With a Neighbor?
Yes — you can sell land with subsurface drainage tile crossing a property line, whether there's a recorded easement, a handshake understanding with the neighbor, or no agreement at all. What changes is the diligence: you disclose the tile's existence and condition in writing, figure out whether any legal right to it actually exists on paper, and expect a conventional buyer's lender or title company to slow down or narrow the deal until those questions are answered.
The problem with drainage tile is that it's invisible. A buyer walking the field can't see a perforated plastic or old clay pipe two to four feet underground, and a lot of sellers who inherited row-crop or former-cropland ground genuinely don't know where their own tile runs, let alone whether the arrangement that lets water flow through a neighbor's line — or lets a neighbor's water flow through theirs — was ever put in writing. That gap between "the field has stayed dry for forty years" and "we can prove why" is the whole issue this guide covers.
This is a different situation than the other easements and agreements Jerez Land has covered on this blog, and worth keeping straight. It isn't the same as a shared or private road maintenance agreement, which governs an above-ground access route rather than underground water management between neighbors. It isn't a pipeline or utility easement either — that's infrastructure owned by a company, with its own recorded instrument and its own compensation terms, not an informal arrangement between two farmers. And it's the opposite problem from swamp or bottomland that floods: that guide is about ground that's naturally wet. A tiled field is dry ground that stays dry only because a buried pipe is still working — which means the moment the tile fails, the field can revert to acting like the wetland it used to be. If you're selling row-crop or former-cropland acreage more broadly, our farmland guide covers the wider set of issues that come up. For more situations like this one, see the Jerez Land blog.
The rest of this guide walks through how to find out where your tile actually runs, whether any real easement backs it up, what you owe a buyer in disclosure, how the nine states Jerez Land operates in treat surface-water drainage differently, and what your options are if the system is undocumented, informal, or broken.
How Do I Find Out Where the Drainage Tile Actually Runs on My Land?
Start with the person who's been farming the ground — a current or recent tenant almost always knows more about a tile system's layout and condition than the landowner does, because they're the one who's hit a broken lateral with an implement or watched a low spot dry out faster than it should. From there, the most useful records typically come from four places: your county USDA Service Center (NRCS and FSA share offices and sometimes hold legacy tile maps or drainage plans from when the system was installed or improved), the county drain commissioner's office if you're in Michigan, historical aerial photography, and physical inspection of visible outlets and risers.
Aerial photos are a genuinely useful tool here — tile lines often show up as faint parallel lines in a field after a rain, visible in older imagery even when there's no as-built drawing on file, and researchers who map tile on research farms rely on exactly this combination of aerial photo interpretation, paper maps, and operator knowledge when no formal map exists. USDA has aerial imagery covering agricultural land going back decades through NRCS and FSA, and county GIS portals or a simple Google Earth historical-imagery pass can sometimes show what a walk of the field can't. Newer tile systems installed with GPS-guided equipment may have a genuine as-built map with GPS coordinates for every line and riser — if your tenant or the installer kept one, that single document does most of the work for you.
Does an Easement for the Tile Actually Exist, or Is It Just an Old Understanding?
A legal right to run drainage tile across a neighbor's land, or to receive water through theirs, can exist in one of four ways: an express easement that was actually drafted and recorded; an implied easement, which can arise from how the properties were used before they were split into separate ownership; a prescriptive easement, built from open, continuous, uninterrupted use of the drainage arrangement for whatever length of time the state where the land sits requires; or nothing at all — a bare, revocable understanding between neighbors that was never put into a form a court or title company would recognize as binding.
That fourth category is where most sellers actually are. Farm drainage tile often predates current ownership by decades, was frequently installed under a verbal understanding between the original farming families rather than a drafted document, and gets inherited along with the land with no one ever revisiting whether it was formalized. An implied or prescriptive easement is a real legal theory, but proving one requires evidence — how long the arrangement has existed, how open and continuous the use has been, whether it was ever interrupted — that most sellers don't have sitting in a file. Don't assume decades of practice automatically equals an enforceable right; treat the honest answer as "probably a license, not an easement" until a title search or attorney says otherwise.
Do I Have to Tell a Buyer About the Drainage Tile?
Yes — treat the tile's existence, any written or unwritten agreement governing it, and any known failure or dispute as a material fact you disclose in writing, the same way you'd disclose a boundary issue or a lien. Buyers rely on what a seller tells them about conditions that aren't visible from a walk of the property, and subsurface drainage tile is about as invisible as a defect gets.
In practice, disclosure means writing down what you actually know: that tile exists, roughly where it runs if you know, whether it's tied into a neighbor's system or a county drain, whether there's anything in writing about it, and whether it has ever failed, backed up, or caused a dispute. You're not expected to produce an engineering survey you don't have — you're expected to be honest about what you know and don't know. If your tenant tells you a lateral has been collapsed for three years and a corner of the field floods every wet spring, that's exactly the kind of fact that belongs in writing before closing, not something to leave for the buyer to discover.
Which State's Drainage Law Applies If My Neighbor's Tile Affects My Field?
Surface-water drainage law in the United States runs on three general doctrines — the civil law rule, the common enemy rule, and the reasonable use rule — and the nine states Jerez Land buys in split across variations of these rather than sharing one uniform approach, so the state where your land sits determines the baseline legal backdrop for any dispute over how water moves between your field and a neighbor's.
Under the civil law rule, a lower parcel is generally obligated to accept the natural flow of surface water from higher ground, and an upstream owner can be liable for artificially concentrating or increasing that flow. Under the common enemy rule, each landowner can generally deal with surface water as they see fit, historically without much liability to a neighbor — though every state that still uses it has narrowed it with some reasonableness limit. The reasonable use rule asks whether a given interference with water flow was reasonable under the circumstances, weighing the utility of the use against the harm it causes. None of these doctrines were written with buried drain tile specifically in mind — they developed around surface runoff — but courts in agricultural states have applied the same framework to disputes over tile-assisted drainage between neighboring farms.

| Michigan | Reasonable use rule layered on a natural-flow baseline — the lower estate must accept the natural flow, but the upper estate can't artificially increase it | Yes — Drain Code of 1956, MCL 280.1 et seq. | County Drain Commissioner / Register of Deeds | Bennett v. Eaton Co., 340 Mich. 330 (1954); Allen v. Morris Bldg. Co., 360 Mich. 214 (1960); MCL 280.1 et seq. |

Butler, 582 S.W.2d 760 (Tenn. App. 1978); Gregory v. Jenkins, 665 S.W.2d 397 (Tenn. App. 1983) |
Oklahoma's doctrine isn't in the table because the sources available didn't rise to a level worth citing to a seller as fact — some describe a version of the common enemy rule, others describe a reasonableness test layered on top of it, and no primary source resolved the conflict cleanly enough to state with confidence. If your land is in Oklahoma, this is a question for a real estate attorney or title company rather than a general rule.
Michigan's Drain Code Deserves Its Own Explanation
Michigan is the one state here with a genuine statutory drainage system rather than pure common-law doctrine. The Drain Code of 1956 (MCL 280.1 et seq.) governs how drainage districts are created, how "county drains" are established and maintained, and how the costs get allocated — and the office responsible for it, the county drain commissioner, is an elected position with real authority: county governments describe the drain commissioner as one of the only elected offices in the state that can levy taxes and borrow money without a public vote. A "county drain" under this system is a public drainage facility the county is responsible for maintaining, which is a different thing from a private tile line two neighboring farmers installed and maintained themselves — and the distinction matters for a seller, because costs tied to a county drain are billed as a special assessment on the property's winter tax bill, a real, checkable line item, not a hypothetical. If you're selling Michigan farmland, check with the county drain commissioner's office on whether any tile crossing your parcel is part of a designated county drain before you assume it's purely a private arrangement between you and a neighbor.
What Do I Do Before Closing If There's No Written Drainage Tile Agreement?
You have three realistic options, and none of them requires inventing a document that doesn't exist: disclose the situation clearly and sell as-is, get a written agreement or easement signed and recorded before closing, or find a buyer who's comfortable taking the property with the tile arrangement undocumented.
Disclosing clearly and selling as-is is the most common path, especially when the tile has worked reliably for years and the relationship with the neighbor is good — you're not obligated to manufacture paperwork that never existed, only to be honest that it doesn't exist. Getting a written, recorded easement signed before closing is the strongest option if the neighbor relationship is solid and you have time before your closing date; it converts an informal arrangement into something a title company can actually insure and a future owner can rely on, and it's worth the legal cost in a lot of cases because it removes the issue permanently instead of passing it along. Paperwork typically needed to sell land is a useful starting point for what a closing package generally requires, including how a new easement gets incorporated into it. Selling to a buyer who's willing to take the property with the arrangement undocumented is the third path, and it's the one that tends to matter most for how you market the property — an undocumented drainage situation is exactly the kind of diligence item that slows a financed, retail transaction and narrows the pool of buyers willing to move forward without it resolved first.
Can I Still Sell If the Tile Is Broken or the Neighbor Plugged It?
Yes, with clear disclosure of the condition and the practical understanding that repair cost and the neighbor relationship — not the legal theory behind the tile — are what a buyer actually cares about. A collapsed lateral, a crushed outlet, or a neighbor who's blocked their end of the line doesn't change your legal ability to sell; it changes what you owe the buyer in terms of honesty about the field's real condition.
Write down what you know: which section of the field is affected, how long it's been an issue, whether it's a full or partial failure, and whether you've had any conversation with the neighbor about it. If the tile crosses into a neighbor's line and they've plugged or altered it, that's a fact worth stating plainly rather than characterizing — let the buyer draw their own conclusion about whether that's a dispute worth pursuing or a cost worth pricing in. A field that floods because tile has failed is functionally different from ground that's naturally wet, and buyers evaluating farmland understand that distinction; what they're pricing is the uncertainty of not knowing the actual repair scope, not the mere fact that a repair is needed.
Does Maintaining Old Farm Drainage Tile Create a Wetlands or Swampbuster Problem?
Generally, maintaining an existing drainage system is treated differently from new drainage that converts a wetland, but the specifics depend on when the original conversion happened and require an actual USDA determination rather than a guess. Swampbuster, the wetlands conservation provisions tied to farm-program eligibility under the Food Security Act of 1985, draws a line around conversions that commenced before December 23, 1985 — those are generally treated as already converted, which affects how new drainage maintenance or improvement on that same ground is evaluated compared to a wetland converted for agricultural production after that date.
NRCS is the agency that actually makes these calls: it issues wetland determinations, minimal-effect determinations, and reviews mitigation plans for converted wetlands, and it's a separate process from a Clean Water Act Section 404 or "waters of the United States" determination that the Army Corps of Engineers handles — a producer can have a USDA wetland determination affecting farm-program eligibility on ground that isn't necessarily a jurisdictional water under the Clean Water Act, and the two shouldn't be assumed to line up automatically. The scope of federal Clean Water Act jurisdiction over wetlands has also shifted following the U.S. Supreme Court's 2023 decision in Sackett v. EPA, which is one more reason to get a current, site-specific read from NRCS or the Army Corps rather than relying on a general rule from a few years back. If your parcel has any history of wetland designation, or CRP or other conservation program involvement, our guide on selling land in a conservation easement or CRP contract covers the related program-compliance questions in more depth — and this is genuinely a situation where a phone call to your county NRCS office before you list is worth more than any amount of guessing.
What Are My Options for Selling Land With a Drainage Tile Easement or Agreement?
You generally have three paths: list the property with a land broker who understands tiled cropland, approach the adjoining neighbor who already benefits from or depends on the drainage arrangement, or sell direct to a cash buyer who evaluates the tile situation as part of underwriting rather than treating an undocumented easement as a reason to walk.
A broker can market tiled farmland effectively, but a listing usually needs the diligence work — locating the tile, confirming or formalizing any easement, gathering NRCS or drain commissioner records — largely finished before financed buyers will move forward, since a lender's title requirements tend to have little patience for an open question about subsurface infrastructure. Selling to the adjoining neighbor can be a clean solution precisely because they already understand the drainage arrangement and have a direct interest in keeping it functioning, though it also means negotiating with the one buyer who has the least incentive to pay a premium. A direct cash sale changes the transaction structure rather than the underlying facts — Jerez Land absorbs the carrying costs, marketing time, and resale risk that come with a parcel whose tile situation isn't fully documented, and a firm, individually priced written offer isn't contingent on a lender's requirements the way a financed purchase is. Request a no-obligation cash offer and we'll walk through what you actually know about the drainage tile, what's worth confirming before closing, and what a straightforward sale looks like from here.

Frequently Asked Questions
I inherited 60 acres of former cropland in Michigan and my tenant mentioned there's drainage tile under the north end, but I've never seen a map of it — how do I find out where it actually runs before I sell?
Start with your tenant — they usually know the tile's rough layout and condition better than anyone, since they're the one who's dealt with wet spots or hit a broken lateral. From there, check with your county USDA Service Center for any legacy tile maps or drainage plans on file, and check with the county drain commissioner's office to see whether any of it is a designated county drain rather than a private line. Historical aerial photography can also show tile lines as faint parallel patterns in a field after rain, even when no formal map exists.
My neighbor and I have always had an understanding that his tile drains onto my property through an old clay line, but nothing was ever put in writing — do I need to fix that before I sell?
Not necessarily, but you do need to disclose it clearly. An undocumented drainage arrangement is usually a bare license rather than an enforceable easement, and you have three realistic options: disclose it and sell as-is, get a written easement drafted and recorded before closing if your neighbor relationship and timeline allow it, or find a buyer comfortable taking the property with the arrangement undocumented. What you shouldn't do is stay silent about it and let a buyer discover it during their own diligence.
We found out during our sale that the tile under our Michigan field is a county drain, not a private line between us and our neighbor — does that change anything?
Yes, it changes who's responsible for maintenance and how costs are billed. Under Michigan's Drain Code of 1956, a "county drain" is a public drainage facility administered by the county drain commissioner, and maintenance costs on it are levied as a special assessment that shows up on the property's winter tax bill — a different arrangement entirely from a private tile line two neighboring farmers installed and maintain themselves. Check with the county drain commissioner's office to confirm the drain's status and whether any assessments are outstanding before you close.
Do I have to disclose a drainage tile easement or agreement when I sell my land?
Yes. Treat the tile's existence, any written or unwritten agreement governing it, and any known failure or dispute as a material fact, the same way you'd disclose a boundary issue or a lien on the property. You're not expected to produce engineering documentation you don't have, but you are expected to be honest in writing about what you actually know — where the tile runs if you know, whether it's tied to a neighbor's system or a county drain, and whether it has ever failed or caused a dispute.
What's the actual difference between a drainage tile agreement and the shared road maintenance agreements or pipeline easements covered elsewhere on this site?
A drainage tile situation involves subsurface agricultural water management between neighboring landowners, and it's frequently undocumented entirely. A shared or private road maintenance agreement covers an above-ground access route and is governed by different law and typically a different kind of recorded agreement. A pipeline or utility easement involves infrastructure owned and maintained by a company, with its own recorded instrument and compensation terms — a fundamentally different relationship than an informal water-sharing arrangement between two farming neighbors.
I know the tile under part of my field is broken and that corner floods every spring — can I still sell without fixing it first?
Yes. A broken or collapsed tile doesn't block a sale, but you do need to disclose the condition clearly and honestly — which section of the field is affected, how long it's been an issue, and whether it's a partial or full failure. Buyers evaluating farmland with known drainage problems are pricing the uncertainty of not knowing the real repair scope, not the mere existence of a repair need, so a clear, specific disclosure generally works in your favor compared to leaving it for the buyer to discover during their own inspection.
