Example Input: [header] How to protect your land rights [title] Build walls and fences. [step] A wall or fence along the border of your property is one of the simplest ways to keep other people out, as well as putting would-be intruders on notice that the land within is private property. [substeps] If you live in a suburban community, make sure the type of fence you want to build is allowed before you begin construction. <sep> (A) Often these prohibitions apply to businesses or potential visitors. However, it's not a reflection of a position of property and cattle or sheep are more likely to deter potential visitors. (B) You also may want to have a survey done to establish the exact boundaries of your property as set forth in your deed. Talk to any adjoining property owners before you construct a fence or a wall.
