A Boundary Line Adjustment refers to the modification of property lines between two or more adjacent parcels of land. Property owners may seek this adjustment for various reasons, such as accommodating changes in land use, correcting erroneous legal descriptions, or resolving boundary disputes.
Boundary adjustments are essentially a subdivision of two or more properties. They are used to adjust the border or boundary of each piece of land and is particularly relevant if your land contains trees, good grazing land, streams, rivers or a coastal margin.
Under such an agreement, the parties acknowledge the true boundary line between the properties, and the encroaching owner releases any claim to the strip of land encroached upon. In return, the “encroached upon” owner allows the encroachment to continue for so long as he/she is not adversely affected.
You and your neighbour can create a 'boundary agreement' to record: the boundary between 2 properties. who's responsible for maintaining a hedge, wall, tree or fence between 2 properties.
These “side” issues include such matters as resolving substandard access to the public road and meeting bulk zoning regulations such as lot width and area. A Boundary Line Adjustment, then, is an Administrative action by the city or county planning authority. In contrast, a Boundary Line Agreement is a judicial action.
In Washington State, boundary trees are considered common property of the adjoining landowners. Any decisions regarding the removal or substantial trimming of these trees must be agreed upon by both parties. Unauthorized tree work can lead to legal action and potential compensation claims.
The Boundary Line Agreement (BL AGR) provides a procedure for County review whenever a point or line determining the boundary between two or more parcels of real property cannot be identified from the existing public record, monuments, and landmarks or is in dispute. RCW 58.04.
