Property lines, fences, easements, and the 15-year clock

This page explains Michigan law in plain English so you know what questions to ask. It isn’t legal advice, and boundary disputes turn entirely on the facts of your land. For your own property, talk to a licensed surveyor or a Michigan attorney before you act — and before you wait.

The short version

Boundary law is the one area of land law where no state agency will save you. Only prevention or a judge. The good news: the rules are old, stable, and mostly about not sleeping on your rights.

Surveys: the GIS map is not a survey

Only a licensed professional surveyor’s monuments mean anything. The parcel lines on your county’s GIS website are drawn for tax mapping. They can be off by many feet, and they are not evidence of where your line is. That’s the single most common misunderstanding in boundary disputes. When to spend the money on a real survey: before building near a line, before a fence, and before closing on rural land.

Adverse possession: the 15-year clock

Here’s the rule that sounds like a myth but isn’t. If someone uses your land openly, exclusively, continuously, and without your permission for 15 years, ownership can transfer. That’s adverse possession — and yes, the neighbor’s encroaching driveway or playhouse can ripen into theirs. The defenses are all about not sleeping:

• Permission defeats it. A written, revocable license — “you may use my beach path until I say otherwise” — is the landowner’s cheapest insurance. The use stops being “hostile” the moment it’s permitted.
• Interrupting it resets the clock — enforced no-trespassing, a lawsuit, a fence.
• It never runs against government land.

Two related doctrines are worth knowing by name. Acquiescence: a fence line both sides have honored for 15 years can become the legal line, even without hostility. Prescriptive easements: 15 years of use earns a right to keep using — a path, not ownership.

Easements: get it in writing, get it recorded

Easements come three ways: recorded (in the deed chain), prescriptive (earned by 15 years of use), and by necessity (landlocked parcels can get court-ordered access). The rural classics — the shared two-track, the driveway over grandpa’s handshake — are exactly the ones that blow up a sale or a friendship decades later. Rule of thumb: if access to your land crosses someone else’s, you want it in writing and recorded at the county register of deeds.

Fences, the antique

Michigan’s line-fence law dates to the 1840s. Adjoining rural owners can be required to share “partition fence” costs, with township “fence viewers” — yes, still on the books — to arbitrate. The law is mostly dormant, occasionally decisive in farm country, and proof that Michigan statute remembers when everyone had livestock.

Trees on the line

Boundary trees belong to both owners. You may trim overhang back to the line. You may not kill the tree. And cutting your neighbor’s trees outright is spectacularly expensive — Michigan’s timber-trespass law allows triple damages. When a tree war starts, call a surveyor and an attorney before a chainsaw.

Mineral rights: you might not own what’s underneath

Mineral rights can be severed from the surface and owned by someone else entirely. It’s a common surprise on old farm and timber land. Michigan’s Dormant Minerals Act lets severed oil and gas interests lapse back to the surface owner after 20 years without recorded activity — but that’s not automatic housekeeping. Check the deed chain at the register of deeds before assuming, and have a title company or attorney interpret what you find.

Who decides

A surveyor establishes the facts. The register of deeds holds the records. An attorney — and ultimately a court — decides the rights. No township office can fix a boundary, and the cheapest outcomes all happen before year fifteen.

The signpost

Your county register of deeds (records and recording) is on your county’s page. The state licenses surveyors through LARA. MSU Extension publishes good plain-English property-law primers. The trespass-and-posting side of protecting your land is its own page. Start at Owning Land in Michigan.
