The One Montana Law That’ll Make City Folks Blink
If you’re from out of state and thinking about buying land in Montana, here’s something that might shock you: You’re responsible for keeping other people’s animals off your land.

In much of Eastern Montana, we live under open range law, which means livestock — like cattle or horses — can legally roam. And if they wander onto your property? That’s on you.
Yes, You Read That Right: Fence Them Out
If you don’t want livestock munching your pasture or walking through your driveway, you’re expected to build and maintain a fence to keep them off — not the other way around.
Even more surprising? If you hit a cow on the road in open range territory, the driver — not the rancher — could be the one liable.
What This Means for Buyers
Open range isn’t just a legal quirk. It impacts:
- Fencing costs and responsibilities
- Neighbor relationships
- Livestock conflict potential
- Insurance considerations
- Property upkeep expectations
And yet, it’s often left out of flashy land listings or overlooked by agents who’ve never ranched a day in their life.
