A witness corner stands in under which circumstance?

A witness corner stands in under which circumstance?

• A. When the true corner cannot be monumented or occupied due to terrain or obstruction
• B. When the true corner is easy to monument
• C. When the corner sight is perfectly clear
• D. When the corner is located underwater

Answer: (A)

The idea being tested is using a witness corner when the exact corner can’t be marked on the ground. A witness corner is a nearby, accessible point that stands in for the true corner so the survey can be carried out and the boundary kept linked to the proper reference. This happens when terrain or some obstruction prevents placing or occupying the actual corner. The labor and measurements tie the witness corner back to the true corner in the records, so the true point can be relocated or re-monumented later if conditions allow. While underwater or other unusual obstacles could also block direct monumenting, the essential reason is the difficulty or impossibility of placing the true corner, not the specific type of obstacle.
