California law recognizes the right of two adjoining landowners to agree on a specific line or marker to act as the property lines between the two parcels, notwithstanding the legal description in each parcel's deed.
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.
A boundary line agreement is a legally binding document that sets clear boundaries between neighboring properties, providing certainty and preventing conflicts.
If you are facing a boundary dispute with a neighbor, the best option is to get in touch with an experienced California real estate litigation lawyer. Your lawyer may be able to help you resolve the situation through negotiation before resorting to the courts.
If the property line goes through the middle of the tree trunk, the tree is jointly owned by you and your neighbor. Since you jointly own such boundary trees, you are allowed to trim them. But if your trimming kills the tree or you cut down the tree entirely, you could be liable for timber trespass.
If you want to check if we have any boundary information, you can get a copy of the title register, title plan, and any 'filed' deeds we have for your own property and your neighbour's property.
