That's effectively impossible. In order to properly locate a single boundary, multiple lines will need to be surveyed as well. Surveying is trigonometry, so you need more than one line/angle to accurately locate a single line. The only way a surveyor can locate a single boundary is if the corners are known (and presumed accurate), then they can mark that line. But in the case like this, they'll need to survey multiple lines to accurately locate the one in question.
And sadly, the burden of proof is on you as the landowner to have an accurate survey if you wish to contest in a court of law.
