Sure, you could rightfully erect a fence on ''the property line." So could your neighbor . But beforehand it would be nice to know precisely where that line is. And before you begin proceeding on the basis of the survey, you may want to consider a principle of real property law known as Boundary by Acquiescence or by Mutual or Tacit Consent!

In other words, your neighbor's hole card that if properly played would decidedly out-rank and trash your over priced land survey!
