What are common causes of boundary line disputes in real estate?

On Behalf of | Jul 22, 2025 | Real Estate Disputes |

Boundary line disputes are common in California real estate and often arise due to unclear property lines or neighbor disagreements. Understanding the main causes can help prevent misunderstandings and resolve issues quickly.

Unclear or outdated property surveys

One of the most common causes of boundary disputes is unclear or outdated property surveys. Over time, property boundaries may not be updated or maintained, leading to confusion. Changes in surveying standards or local regulations can also impact boundary definitions. Property owners relying on old surveys may accidentally build on a neighbor’s land, leading to disputes.

Encroachments

Encroachments happen when a structure, like a fence or shed, extends beyond the property boundary. This often occurs unintentionally, as owners may not know their exact property lines. Over time, encroachments can become contentious if one party feels their rights are being violated. In some cases, neighbors may even claim ownership of the land where the encroachment occurs, complicating matters.

Inaccurate property descriptions in deeds

Inaccurate property descriptions in deeds or titles can also cause disputes. Older deeds may contain vague or imprecise boundary descriptions, making it difficult to determine where one property ends and another begins. Without clear descriptions, conflicts can arise between property owners.

Changes to the landscape

Natural changes like erosion or shifting rivers can also affect boundary lines. Over time, these changes may alter the landscape and shift property boundaries, leading to disagreements between neighbors about ownership.

Adverse possession

California’s adverse possession laws allow someone to claim land they’ve occupied for a specified period, usually five years. If a person occupies part of a property without permission for long enough, they may claim it as their own, causing boundary disputes.

Boundary line disputes can be stressful, but ensuring accurate property surveys and resolving conflicts early can help prevent legal issues.
