What Found and Set Mean on a Plat
Found means the surveyor recovered a monument already in the ground. Set means that surveyor placed a new one. The two words tell you who is responsible for the mark and whether it is original evidence or a new marker.

Two verbs in the legend
Plats abbreviate these ideas in different ways: Fnd or Fd for found, Set for set, IPF for iron pipe found, IRS for iron rod set. The legend on that sheet controls the abbreviations. A found monument is evidence of an earlier survey or of an original corner. A set monument is a new mark this surveyor placed, often because nothing reliable was there, or because a new lot corner was being created. Mixing them up changes the story. A found 1-inch pipe may be decades older than the plat you are holding. A set rebar with a plastic cap dates from the survey that capped it.
Why the difference matters to the line
In a retracement, found monuments that match the record are strong evidence of where the corner was established. A set monument is only as good as the reasoning that put it there. The narrative or the certificate should say why a new mark was set: nothing found, the old mark was disturbed, or a new corner was created by this plat. If the sheet says found at a lot corner of a recorded subdivision, that pipe is evidence of the plat corner. If it says set at a calculated point with no older monument, you are looking at this surveyor’s opinion of the record, monumented. Either way, the county GIS line is not what was found or set.
What you should copy into notes
Write the size, the material, and the word found or set. A half-inch rod and a one-inch pipe are different objects, and the next reader needs to know which one the plat means. If a cap is named, copy the license number or the firm name stamped on it as the plat states it. Do not dig the monument up to read the cap. If leaves or soil hide it, a surveyor can expose it carefully. A hardware-store magnet or a measuring wheel will not tell you whether the rod was found or set, and it will not make a phone photo into a survey.
What to do next
- Read the legend so you know how that sheet abbreviates found and set.
- Copy material, size, and found or set for each corner you care about.
- Read any note that says why a new monument was set.
- Keep the recorded plat, not the parcel viewer, as the source of those words.
The mix-up to avoid
Calling every iron a found original. A set cap from last year is new work. Treating it as a nineteenth-century corner gives it a history the plat never claimed.
Questions people ask
Does set mean the surveyor disagrees with an older pin?
Not by itself. Set can mean a brand-new lot corner on a new plat, where nothing should have been in the ground yet. It can also mean a replacement. The note beside the symbol, or the survey narrative, is what tells you which of those happened.
If two plats disagree, found versus set, which one wins?
You do not pick a winner from a website. A later plat that found the older monument is reporting recovery. A later plat that set a new rod in a different place needs a reason. A licensed surveyor compares both records to the marks in the ground.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
