"Buying a Minnesota Home With a Well: What Does the Well Disclosure Tell You Before You Sign?"

By Jeff Moran, NMLS #483943 · September 21, 2026

Before you sign a purchase agreement in Minnesota, the seller has to tell you in writing about every well they know of on the property, and whether each one is in use, not in use, or sealed. You'll want to read the status word beside each well before anything else, because a well that is not in use has to be either sealed by a licensed contractor or carried on a state permit. Once the property transfers, that job belongs to you.

Most of the paperwork a Minnesota seller hands you is about the home, but this one page is about the land. The statute has the seller map the wells from whatever information they have, so what reaches you is often a sketch with a circle for each one. The word beside each circle decides whether you are buying a working water supply or something somebody still has to deal with.

What is a Minnesota well disclosure, and when are you supposed to get it?

It is a written statement the seller owes you before the purchase agreement gets signed. If it arrives after you have already signed, the statute's timing has not been met, and you have lost the window where the information could still change what you agreed to.

Minn. Stat. 103I.235 says that before signing an agreement to sell or transfer real property, the seller has to disclose in writing to the buyer the status and location of all known wells on the property. Either they give you a statement that they do not know of any wells there, or they give you a full disclosure statement. The full version carries the legal description and the county, plus a map drawn from the information available to them, showing where each well is as closely as they can place it.

That map is not a survey and is not supposed to be. It is the seller's best account of what is on the land, so you'll want to walk the property with it in your hand rather than reading it at the kitchen table. The Minnesota Department of Health holds these records once they are filed, and its well disclosure pages are the plain-language version of the statute.

What do the three well statuses mean for you?

The statute gives each well one of three statuses, and each one puts you in a different situation.

In use means the well is operated on a daily, regular, or seasonal basis. The statute counts domestic use, irrigation, fire protection, washing and emergency pumping. So a well that runs a lawn irrigation system in the summer and stays quiet all winter is still in use.

Not in use means exactly what it says, and it is the status that carries a cost for whoever owns the property next.

Sealed means the well has been permanently closed by somebody licensed to do it. Under Minnesota's rules a well only counts as sealed when a Well and Boring Sealing Record for it is on file with the Department of Health. An old well that somebody filled in with rock and dirt forty years ago was never sealed in the sense the state means.

The status does not tell you whether the water is any good. A well can be in daily use and still produce water you would want treated, so water quality is a separate question with its own test. The national side of that is covered in what a lender asks about a home with a well and septic.

What happens to a well marked not in use after you own the home?

Minn. Stat. 103I.301 says a well that is not in use has to be sealed, unless the property owner holds a maintenance permit for it. The sealing has to be done by a licensed well contractor or a licensed well sealing contractor, which puts it outside what you or a handyman can take care of.

A maintenance permit is the other way to handle it. It lets an unused well stay unsealed as long as it is properly maintained, it runs for one year, and the state charges an annual fee for it. When the property changes hands, the seller's permit does not come with the property, so the new owner either applies for their own or has the well sealed.

Where neither step has been taken at the time of the property transfer, the Department of Health says it becomes the buyer's responsibility to choose one of the options and follow through with it. Their sealing unused wells page carries the current requirements and the current permit fee, and you'll want to take the fee from there rather than from an article, because the published figures for it have moved.

So a well marked not in use is a cost you have not paid yet. What the sealing runs depends on how deep the well is and how it was built, so nobody can quote you a number from a distance. You'll want to call a licensed contractor for an estimate while the seller is still at the table, rather than after closing when the only person who can pay for it is you.

What is the well disclosure certificate, and why does it show up at recording?

The disclosure statement you read before signing and the certificate filed at the end are two different documents doing two different jobs, and the second one is where a closing can stall.

At closing, the information from the disclosure statement goes onto a well disclosure certificate, along with your name and mailing address. The certificate also carries the quartile, section, township and range where each well is located, and it is signed by the seller or by somebody authorized to act for them. The county recorder or registrar of titles collects a fee for receiving it, and the statute puts that fee on the buyer, or on whoever is recording the deed. The amount is set in the statute and has already been raised once, so your closer will quote you the figure that applies on your closing date.

The certificate itself does not go into the county's records. The recorder notes on the deed that a certificate was received, and then the certificates get transmitted to the Department of Health. That is how the state keeps a running map of where the wells are.

The statute allows two shortcuts. A separate certificate is not required when the deed itself carries a line in which you, as the buyer, certify that you do not know of any wells on the property. It is also not required when the deed certifies that the number and status of the wells have not changed since the last certificate filed. The statute excludes a sale of severed mineral interests and an individual condominium unit, so a condominium purchase in Minneapolis or St. Paul does not raise this question at all.

Does your lender ask the same questions the state asks?

No.

Your lender is asking whether the property has a safe, adequate, continuing supply of drinking water, and whether the property can be financed on that basis. That usually gets answered with a water test and, where the program requires it, a look at the system itself.

Minnesota is asking a records question instead. The state wants an account of every hole in the ground, whether it is being used, and who is now responsible for the ones that are not. An old unused well in a pasture can be completely irrelevant to your loan and still leave you with a sealing bill three months after you move in.

For the rest of it, how a Minnesota mortgage closing works covers the deed tax, the mortgage registry tax, and closing through a title company rather than an attorney.

What are the steps for a Minnesota buyer?

The order below matters, because two of these steps depend on somebody else's schedule.

  1. You'll want the well disclosure statement in hand before you sign anything, since that is when the statute says you are supposed to have it. The status word beside every circle on the map is the part to read first.
  2. It is worth walking the property with that map and counting the wells yourself. An old well head can be hidden under a board, behind a shed, or in tall grass, and the seller may genuinely not remember one.
  3. If any well is marked not in use, please ask the seller for the maintenance permit, all pages, and for any well sealing records they hold on the property. Those documents tell you which situation you are actually in.
  4. A sealing estimate from a licensed well contractor is quick to get, and you'll want it while your inspection window is still open.
  5. Then you and your agent decide whether the sealing becomes a repair the seller handles before closing or a credit you take at the table. Either one is a negotiation, and both are ordinary.
  6. Before closing, your closer can confirm that the well disclosure certificate is prepared and that the recording fee is on your closing statement where you expect it.

If the outcome is a credit rather than a repair, how a seller credit works at closing covers what a credit can and cannot be used for.

Where this goes wrong

The status word gets skimmed. It arrives in a stack of disclosures that are otherwise about the home, and the one page about the land gets initialed along with the rest.

The sealing gets treated as the seller's job. The statute requires the seller to disclose what is on the property, and nothing in it makes the seller seal an unused well. Once the property transfers with one on it, the choice and the cost belong to the new owner.

The old permit gets treated as coverage. A maintenance permit the seller has been renewing every year keeps the well legal for as long as they own the property, and the new owner still has to apply for their own or have the well sealed.

An illustration, so the order is clear

Details below are made up to show the mechanism, not a real file and not a quote.

A couple goes under contract on five acres outside a small Minnesota town. The disclosure statement shows two wells. One is marked in use and serves the home. The second is drawn near the old barn and marked not in use. They walk the property with the sketch in hand and find that second well head under a plywood cover.

They ask the seller's agent for the maintenance permit and for any sealing record, and the answer comes back that there is no permit and there never was one. That tells them where they stand. They call a licensed well sealing contractor, get an estimate that week, and take it to the seller inside their inspection window. The seller agrees to handle the sealing before closing, and the contractor files the sealing record with the Department of Health so the well counts as sealed.

Their closer prepares the certificate for the remaining well, the recording fee lands on the closing statement where they expect it, and nothing about the loan changes. If they had found that second well after closing instead, the same work would still have needed doing, and it would have been theirs to pay for.

What to do now

If you are shopping in Minnesota, you can put the whole payment picture in front of yourself while there is still time to act on it. When you want to see it with your own numbers, the rate tool is here. You'll see rates priced for your own scenario and your debt ratio, with closing costs built against Minnesota's deed tax and mortgage registry tax rather than a national average. No credit pull, no account, nobody calls you.

When you are ready for the letter a seller will take seriously, get pre-approved for a Minnesota mortgage and the income, debts and credit get reviewed properly instead of estimated from a form. After closing, Minnesota homestead classification is a separate application with its own deadline, and it changes the tax line in the payment you just agreed to.

Nothing here is a loan approval, a denial, a commitment to lend, or legal advice. The well rules belong to the Minnesota Department of Health and to the statutes cited above, and the current fees and forms belong to that department and to your county recorder.

Common questions

Does a seller in Minnesota have to disclose a well before I sign?

Yes. Minn. Stat. 103I.235 requires the seller to disclose in writing, before an agreement to sell or transfer is signed, the status and location of all known wells on the property. They either give you a statement that they know of no wells, or a disclosure statement with the legal description and the county. That statement also carries a map drawn from available information, showing where each well is located as closely as they can place it. The timing is part of the requirement, so a disclosure that shows up after you have signed has not been handled the way the statute describes.

What does it mean when a Minnesota well is marked not in use?

It means the well is not being operated on a daily, regular or seasonal basis. Under Minn. Stat. 103I.301, a well that is not in use has to be sealed unless the property owner holds a maintenance permit for it. Sealing has to be done by a licensed well contractor or a licensed well sealing contractor, and the well only counts as sealed once the sealing record is on file with the Minnesota Department of Health. A well marked not in use with no permit behind it is an open item, and what it costs to resolve depends on the depth and construction of the well.

Who is responsible for sealing an unused well after a Minnesota home sale?

The property owner is, which means it becomes yours once the transfer is done. The Minnesota Department of Health addresses this directly. Where the well has not been sealed and no maintenance permit is in place at the time of the transfer, it is the buyer's responsibility to choose an option and follow through with it. A maintenance permit the seller held does not transfer with the property, so a new owner who wants to keep the well applies for their own.

What is a Minnesota well disclosure certificate, and who pays the fee?

It is the document filed with the deed at recording, separate from the disclosure statement you read before signing. It carries the disclosure information, your name and mailing address, and the quartile, section, township and range for each well, and it is signed by the seller or somebody authorized to act for them. Minn. Stat. 103I.235 has the county recorder or registrar of titles collect the fee from the buyer, or from whoever is recording the deed. The certificate is not kept in the county's records. The recorder notes on the deed that it was received and transmits the certificate to the Minnesota Department of Health.

Can I hold the seller responsible if a well turns up that was never disclosed?

Minn. Stat. 103I.235 gives you a route. A seller is liable to the buyer for reasonable attorney fees and for the costs related to sealing the well. That applies where the seller knew or had reason to know of the well or its status and failed to disclose it at the time of sale. The statute gives you six years after the purchase to bring the action. Using it means hiring a lawyer and proving what the seller knew, and you own the well the whole time that is going on. That is why it is worth walking the property with the disclosure map before you sign, while an undisclosed well is still something you can raise with the seller rather than something you have to sue over.
