Sell your land in Montana.

Montana's Subdivision and Platting Act draws its line at 160 acres. A division that creates a parcel below that, and that cannot be described as a quarter aliquot part of a section, is a subdivision unless an exemption applies — which is why so much of rural Montana sits in odd, exempt-created shapes.

Figures describe Montana generally. Counties administer their own sales and their own calendars — your county treasurer is the only source for a payoff figure or a sale date you can act on.

Local detail

What actually matters about land in Montana

The 160-acre line and its exemptions

Montana reviews land divisions under the Subdivision and Platting Act, Title 76, chapter 3 of the Montana Code Annotated. Section 76-3-103 defines a subdivision as a division creating one or more parcels of less than 160 acres that cannot be described as a one-quarter aliquot part of a government section. Below that line, review is the default and exemption is the escape. Section 76-3-207 lists the exempt divisions, including a single gift or sale in each county to each member of the landowner's immediate family, and divisions covenanted to agricultural use only. Exempt divisions still require a certificate of survey, still answer to county zoning, and fail if the method of disposition was adopted to evade the chapter.

Agricultural valuation has an income test

Agricultural classification cuts the assessed value sharply, and Montana grants it on acreage and use together. Under MCA 15-7-202, contiguous parcels totaling 160 acres or more under one ownership are eligible each year that none of them is devoted to residential, commercial, or industrial use. Below 160 acres the land must be actively devoted to agriculture and produce at least $1,500 in annual gross income from agricultural products. Parcels of 20 acres or more but less than 160 that fail the test are not simply reclassified — MCA 15-6-133 calls them nonqualified agricultural land, values them at grazing land productive capacity, and taxes them at seven times the agricultural rate. Assessments are handled by the Department of Revenue.

Water is appropriated, and small wells are exempt

Montana follows prior appropriation, administered by the Department of Natural Resources and Conservation: a right carries a priority date, a source, and a defined place of use, and it does not attach to acreage by itself. The practical route for a rural building site is the exempt well. MCA 85-2-306 allows an appropriation of groundwater outside a controlled groundwater area without a permit where the use is 35 gallons a minute or less and does not exceed 10 acre-feet a year, subject to a notice of intent filed with the department beforehand and a notice of completion afterward. Whether several wells serving one division count as a single combined appropriation is contested ground.

The public can use your stream

Montana's Stream Access Law, MCA 23-2-301 and following, is more favorable to the public than what most out-of-state owners expect. Surface waters capable of recreational use may be used by the public up to the ordinary high-water mark without regard to who owns the land beneath them. MCA 23-2-301 defines that mark as the line water impresses on land by covering it long enough to leave physical characteristics distinguishing the area below from the area above. Fishing, floating, swimming, boating and incidental picnicking within that line are lawful on a stream running through deeded ground. The law does not let the public cross your posted land to reach the water, which is where most disputes actually start.

Questions

Selling land in Montana

Do I have to give a disclosure statement for vacant Montana land?

No. Montana's residential disclosure requirement, MCA 70-20-501 and following, was enacted in 2023, and it reaches only residential real property — which MCA 70-20-501 defines as property improved by a building or other structure designed or intended for occupancy as a residence with one to four dwelling units, or an individually owned unit. Bare ground has no such structure, so no statutory form is owed. You still cannot misrepresent what you know, and a buyer will ask about access, water, and septic feasibility regardless.

Can I split my Montana land using the family transfer exemption?

Sometimes, and it is narrower than it sounds. MCA 76-3-207 exempts one gift or sale outside a platted subdivision in each county to each member of the landowner's immediate family. The statute requires each resulting parcel and any remainder to be at least five acres unless zoning allows smaller, and it restricts the recipient from conveying the parcel for a period after the division. A certificate of survey is still required, the county still reviews for errors, and an exemption used to evade the chapter does not hold.

My land has agricultural classification. What happens when I sell?

Classification is tested against use each year, so it does not simply ride along with the deed. MCA 15-7-202 keys eligibility to acreage and actual agricultural use: 160 contiguous acres or more under one ownership qualify absent residential, commercial or industrial use, while smaller ground must be actively devoted to agriculture and generate $1,500 or more in annual gross income. A buyer who stops farming a 40-acre parcel can land in the nonqualified agricultural land category under MCA 15-6-133, taxed at seven times the agricultural rate.
