Coburns accepts boundary instructions in High Wycombe. Start with the two property addresses, the disputed section and the evidence you already hold. Site attendance is arranged by agreement, subject to the instruction and access.

Changes in ground level need a careful scope

For a High Wycombe or Marlow instruction on a sloping site, show where the ground levels change as well as where the boundary feature stands. A wall supporting a raised garden may have a different footprint below ground. If structural movement or loss of support is alleged, the boundary investigation and any engineering assessment should be scoped separately.

Useful evidence for this type of instruction

  • Photograph steps, retaining walls and the level change from safe positions.
  • Provide section drawings where they exist, not only a plan view.
  • Explain whether the concern is ownership, stability, access or a combination.

Local records to consider

Buckinghamshire Council’s record route can help locate plans and sections from earlier development. A section may explain a change in levels that is difficult to understand from a flat site plan alone.

Council planning drawings can help explain past layouts. They do not determine the legal boundary or replace title evidence. The correct council depends on the actual property address, and older documents may need to be requested.

Choose the right boundary service

Early Neutral Evaluation

A preliminary assessment of the key evidence and a proportionate next step: £400 + VAT desktop only, or £750 + VAT with a site visit.

Boundary Investigation Report

A fuller evidence review and reasoned opinion, from £950 + VAT, typically £950–£1,200 + VAT depending on title complexity.

Private joint expert: binding determination

Both parties appoint one independent expert and agree in writing to accept the determination. £1,800–£2,400 + VAT total, approximately £900–£1,200 + VAT each on an equal split. Scope and fees are confirmed before instruction.

Will a boundary report assess whether a retaining wall is safe?

Only if that expertise and task are expressly included. A structural concern may need an appropriately qualified engineer in addition to the boundary investigation.

Important: General information, not legal advice. Boundary disputes are fact-sensitive. A private expert determination binds the parties under their agreement; a report alone does not automatically bind a neighbour or alter the Land Registry register. Obtain appropriate legal advice where litigation, binding terms or changes to title are involved.
