ADVERSE POSSESSION MY AZZZZZ.
What sort of people would actually do this? Perhaps the kind that would sue because they spilled hot coffee on themselves, or slipped on some ice, or are unable to accept and at the minimum acknowledge their own responsibilities.
I have some land. I pay taxes on it, I pay homeowners fees on it, I paid for it! It is mine. I let it sit for years without building on it. My neighbors decide to make a path through it, and to use it frequently to cut across to get to their back yard. Fine, no big deal. I'll share.
Then one year I decide, I'm ready to build my dream house on it. It has an awesome view of the Flatirons etc, etc. I go to put up a fence on MY PROPERTY.
Nope, my neighbors, decide that it should be theirs. They claim, successfully, that through "adverse possession" they have a right to it. Their crony, another judge in Boulder, allows this.
Then they want the original owners to also pay their legal fees and then they go back and try and get another 9 inches of the land! Keep in mind, this is land in Boulder, Colorado and worth a million dollars.
Pathetic.
