San Jose FAQ
Can my neighbor force me to pay half for a new fence I did not want?
Civil Code 841 presumes equal sharing, but you can rebut this by showing the fence exceeds reasonable needs, you cannot afford the share, or it confers little benefit. Respond in writing within 30 days.
Does the county mediate fence disputes?
No. Santa Clara County does not mediate civil boundary fence disputes. Project Sentinel and other nonprofits offer low-cost mediation, or owners may file in Superior Court.
Sunnyvale FAQ
Can my neighbor refuse to pay half for a replacement fence?
They can try to rebut the presumption by showing hardship or lack of benefit. A judge in small claims decides if the rebuttal is valid.
What if the fence is on my property, not the line?
If the fence sits entirely on one parcel, Civil Code 841 does not automatically require cost sharing. A survey clarifies whether the fence is truly a boundary fence.
