A clear guide to the laws surrounding Japanese Knotweed, including property responsibilities, neighbour disputes, anti‑social behaviour powers, and legal obligations for homeowners and landowners.
A practical guide explaining your legal responsibilities if Japanese Knotweed is found on your property, including neighbour disputes, property sales, and UK legislation.
Japanese Knotweed is not illegal to have on your property, but you are legally responsible for preventing it from spreading to neighbouring land. Allowing Knotweed to encroach onto another property can lead to civil claims for damages.
Under Schedule 9 of the Wildlife & Countryside Act, it is an offence to plant or cause Japanese Knotweed to grow in the wild. This includes improper disposal of soil or plant material.
Councils and police can issue Community Protection Notices (CPNs) if Knotweed on your land is causing a nuisance or risk of harm to others.
Encroachment is one of the most common legal issues involving Knotweed. If it spreads from one property to another, the affected party may claim damages.
When selling a property, you must declare Japanese Knotweed on the TA6 Property Information Form. Failure to disclose can lead to misrepresentation claims.
Developers have additional responsibilities due to soil movement, waste disposal and construction sequencing.
