What is a "Parol Agreement" in land surveying terms?

A "Parol Agreement" in the context of land surveying refers to an oral agreement between landowners regarding a boundary line. This type of agreement is significant in land surveying as it can have implications for property rights and usage, especially in situations where formal, written documentation may not exist but where landowners have come to a mutual understanding.

In many cases, parol agreements arise when neighbors verbally agree on where their properties begin and end based on longstanding practices, historical usage, or informal conversations. Such agreements can lead to established boundaries that, while not formally recorded, may still be recognized in certain legal situations if they meet specific criteria over time, especially when they demonstrate a pattern of clear acceptance and use by the parties involved.

The other choices represent different concepts that don't align with the definition of a parol agreement. For instance, a written contract is a formal and legally binding document, while a legal document for formalizing property transactions refers to specific paperwork involved in transfers of ownership. A detailed mapping of property boundaries is more aligned with methods of surveying and establishing physical demarcations rather than informal discussions. Thus, the essence of a parol agreement lies in its oral nature and the informal, interpersonal understanding it fosters between neighbors regarding boundaries.
