Legal Principles and Professional Practice

The evidence hierarchy governs everything

Boundary questions are decided by rank, not by preference. The controlling order in retracement is: natural monuments (shorelines, rivers, trees), then artificial monuments called for in the record (iron pins, stone posts, set caps), then courses and distances, then area or quantity. Learn the distinction between an original survey and a retracement: the retracement surveyor does not create new corners, but re-establishes the position of the original ones.

Unwritten rights - adverse possession, boundary by agreement, acquiescence, estoppel, practical location - can fix a line that the deed does not describe. Know their elements and their statutory periods.

Professional practice questions test the standard of care (what a reasonably prudent surveyor in the same community would do), duty to the public interest, conflicts of interest, confidentiality, records retention, and the fact that a survey is a professional opinion, not a warranty of title.

Traps

  • 'The measured distance differs from the deed, so the deed is wrong.' No - monuments control.
  • Applying senior-rights reasoning where the question describes a simultaneous conveyance.
  • Treating a found pin as conclusive without testing whether it is original, a later replacement, or a neighbor's stray.
  • Confusing adverse possession (statutory, fee) with prescription (easement by long use).
  • Assuming licensure is portable between states.

Worked example

A deed reads 'thence N 00°00'00" E, 200.00 feet to an iron pipe.' The pipe is found at 198.65 ft with a legible cap matching the record. The pipe holds; the line is 198.65 ft on the ground. The record distance is evidence of intent but is subordinate to the monument.
