Conditional Line

Definition and meaning of Conditional Line in real estate.

A conditional line is an agreed-upon property boundary line established by adjacent landowners that has not been verified by a professional land survey.

In more detail

Neighbors often create these informal boundaries for convenience, such as when placing a fence, planting a hedge, or clearing land. Over time, these agreements can lead to confusion or legal disputes if one owner decides to sell their property or if a new survey reveals that the actual legal boundary lies elsewhere.

In some jurisdictions, if a conditional line is respected and treated as the boundary for a long period, it may become legally binding under doctrines like boundary by acquiescence. To avoid future title issues, buyers should always verify property lines with a professional survey rather than relying on a seller's word or a fence line.
