Japanese knotweed disputes in Nottingham often reach a point where progress stops. A sale stalls. A neighbour dispute escalates. Different survey opinions circulate, but no one is able to make a decision.
At that stage, what’s usually missing is clear, independent evidence focused specifically on Japanese knotweed. A Part 35 expert witness report provides an impartial position that solicitors, lenders, insurers, and courts can rely on.
If a solicitor, mortgage provider, or insurer has mentioned the need for Part 35 evidence, we can confirm quickly whether it’s required and explain the next step without delay.
Free initial advice • Independent expert evidence • Typical 10-day turnaround
In many Japanese knotweed disputes, progress only resumes once there is independent evidence everyone can rely on.
Typical situations where a P35 CPR compliant report for Japanese Knotweed is required when:
A property sale or purchase has stalled due to knotweed concerns
A neighbour dispute has escalated beyond informal discussion
A mortgage lender or insurer has requested independent evidence
Conflicting surveys or opinions are preventing agreement
If any of these apply, independent Part 35 evidence can help move things forward.

Across Nottingham, Japanese knotweed disputes often arise where infestations originate from transport corridors and encroach onto residential properties. We provide proportionate Part 35 expert evidence to support dispute resolution.
A private residential property in Nottingham, where a single stand of Japanese knotweed was identified at the rear of the property.
Stand 1 (c.150 m², 2 m high, 20+ years) is located near a railway line, the likely primary source of the infestation. Visible knotweed on neighbouring land supports the conclusion that, on the balance of probabilities, rhizomes have spread beneath the boundary from the railway embankment. A crack in the rear wall was noted, though a structural survey is recommended to confirm any damage.
Specialist herbicide spraying and injection was recommended, with ongoing management of the source on the railway line to prevent repopulation.
The expert report confirmed the likely origin and pathway of spread, providing a clear strategy for effective long-term control and protection of the affected property. Treatment costs were assessed in line with the recommended professional programme.
No unnecessary steps. No lost time.

Yes. We prepare CPR Part 35–compliant expert witness reports for matters arising across Nottingham. Reports frequently relate to invasive plant issues and land condition disputes, including Japanese knotweed and similar species affecting residential, commercial, and brownfield development sites.
Part 35 reports are commonly required where specialist opinion is needed to assist the court. In Nottingham, this often includes disputes involving urban redevelopment, brownfield site development, alleged spread of invasive plants, or conflicts between neighbouring landowners.
Reports may be relied upon by solicitors, barristers, surveyors, developers, insurers, landowners, and the court. The expert’s overriding duty is to the court, and opinions are provided independently, regardless of who provides instructions.
Yes. All reports are prepared in accordance with CPR Part 35 and the associated Practice Directions. They include statements of truth, declarations of independence, and clear explanations of inspection findings, invasive plant assessments, methodology, and conclusions.
Yes. Experts may be required to attend joint expert meetings, case management hearings, or provide oral evidence under cross-examination. Attendance is provided where instructed and directed by the court.
