According to standard procedure, property boundaries in the United States are not determined by what a map app says or what a contractor eyeballs or even what two neighbors agree looks about, right? Property boundaries are determined by recorded legal documents and professional land surveys. period. Every parcel of land has something called a plat map, which is basically the official blueprint filed with the county that defines where each property begins and ends.
When surveyors originally divide land, they install physical markers, usually iron pins driven into the ground that represent the exact legal corners of the property. Those pins can sit underground for decades, sometimes covered by grass, soil, or landscaping. But legally, there’s still the reference points. From a legal perspective, if a neighbor removes a boundary structure and builds inside your property line without permission, that’s not just a misunderstanding.
That can fall under trespassing, property damage, and encroachment, which courts tend to take very seriously because property rights in the US are extremely well protected. But there’s another layer to this that’s more psychological. This is a psychological trap people fall into all the time, especially homeowners who are in the middle of expensive renovations.
Once someone has invested a lot of money into a project, they start convincing themselves they must be right. Because admitting they’re wrong means admitting they’ve just burned thousands of dollars. It’s called commitment bias. The more Brent spent on his backyard resort, the more confident he became that the fence had to be correct because the alternative was admitting he just built half a pool deck on someone else’s land.
