Monument markers identify boundary corners physically. Types: iron pins (most common in modern surveys), stone markers (older properties), concrete monuments, wooden stakes (temporary). Monuments serve as: boundary proof (physical evidence of boundary), reference points for subsequent surveys (re-establish property corners if lost), deed description reference points. Monument placement is professional surveyor's responsibility: placed at specified locations per deed description. Monument loss or damage creates problems: boundary becomes unclear, disputes possible, subsequent survey needed to re-establish. Some properties lack clear monuments: older boundaries might be lost, requiring new survey. Survey locates monuments: identifies and documents existing monuments, places new ones if needed. Understanding monuments: they're proof of boundaries. Protecting monuments is property owner's responsibility: don't remove, damage, or build over monuments. Some jurisdictions have monument protection laws: removing survey monument is felony in some states.
Pro Tip
Know where your monuments are located. If they're lost or removed, re-establishing boundaries requires new surveys. Some jurisdictions have laws protecting survey monuments—damaging or removing them is serious.
Example
Property corner marked with iron pin set 6 inches below ground surface, identified on survey, used as reference for all property measurements.
