Completing a RICS-Compliant Boundary Survey Report: A Worked Example

The scenario

Mr. Rose and Mrs. Oak (from Asset 2: Desktop Study Walkthrough) instruct an Icelabz surveyor jointly to act as Single Joint Expert (SJE) under the RICS Boundaries 4th edition. After the desktop study and site visit, the surveyor sits down to write the report. This article walks through the report section by section, with practical tips from each.¹

1. Cover page

The cover page establishes the credentials and the scope at a glance. It includes:

• Title — "Boundary Survey Report"
• Property address — full postal address with postcode
• Title number — HM Land Registry title number
• Prepared for — both parties' names and addresses (since this is a joint instruction)
• Prepared by — surveyor's name (Bhavesh Ramburn, MRICS), firm name (Icelabz), firm address
• Date of survey — when the site visit happened
• Date of report — when the report is issued
• Report reference — internal reference for filing

Tip: the cover page should be self-contained. A stranger picking up the report in 10 years' time should be able to identify the property, the parties, and the surveyor from the cover alone.

2. Executive summary

The executive summary is a single paragraph that states the surveyor's opinion in plain English:

"Following the desktop study and site visit conducted on 12 March 2026, I confirm that the legal boundary between Rose Cottage (title BD123456) and Oaklands (title BD789012) follows the line of the original 1922 stone wall from vertex V1 in the north (at the base of the original oak tree) to vertex V6 in the south (at the bank of the stream), with a minor adjustment at the northern end per the 1960 Boundary Agreement. The full boundary is 32.14m long. Coordinates of each vertex in OSGB36 are listed in Appendix A. The opinion is given in my capacity as a Single Joint Expert appointed jointly by both parties."

Tip: the executive summary is what most readers will read. It should be complete enough to stand on its own but not so long that it dilutes the headline opinion.

3. Instruction

This section sets out the scope and the limitations:

• Client(s): Mr. Rose (Rose Cottage) and Mrs. Oak (Oaklands), jointly
• Instruction date: 15 February 2026 (date the joint letter of instruction was signed)
• Scope: "To determine the legal boundary between Rose Cottage and Oaklands along the eastern edge of Rose Cottage's garden, from the oak tree at the north to the stream at the south."
• Purpose: To resolve the dispute regarding the position of the newly erected timber fence at Oaklands.
• Exclusions: the position of the boundary to the north of the oak tree; the position of the boundary to the south of the stream; rights of light; party wall matters; the structural condition of any building.

Tip: the exclusions are as important as the scope. They tell the reader what the surveyor is NOT opining on. Missing exclusions lead to scope creep and disputes about whether the surveyor has answered the question they were instructed on.

4. Documents consulted

A chronological table of every document the surveyor reviewed:

Tip: every document must be listed. If a document is not listed, a reviewer cannot verify what the surveyor did or did not consider. The list is part of the audit trail.

5. Legal framework

A short statement of the applicable law:

• Land Registration Act 2002, section 60 (general boundary rule)
• RICS Boundaries: Procedures for Boundary Identification, Demarcation and Dispute Resolution (4th edition, 2022)
• HM Land Registry Practice Guide 40 (Plans, Boundaries and Easements) and Supplement 5 (Determined Boundaries)
• Common law principles (hierarchy of calls, hedge and ditch presumption, doctrine of ancient lights) per Thorpe v Frank (1985), Acco Properties v Severn (1991), and Alan Wibberley v Insley (1999).

6. Physical evidence on site

A walk-around description, with photographs referenced by number:

"Northern boundary: the original oak tree is still standing at the northeast corner. No physical monument found at the tree base, but a low mound consistent with the original ditch bank is visible to the south. Eastern boundary: the line of the original 1922 stone wall is clearly visible as a row of stones partially embedded in the soil, with a continuous line of mature bramble growing along the wall foundation. The wall has been partially demolished at two points (P12, P27) but the foundation remains. Southern boundary: the stream runs along the southern edge, with the original bank visible (P44-P47)."

Each feature is described, photographed, and located in OSGB36.

7. Analysis — applying the hierarchy of calls

This is the substantive section where the surveyor applies the legal rules to the evidence:

"Applying the hierarchy of calls per Thorpe v Frank and the RICS 4th edition, the surveyor's opinion is that the legal boundary follows the line of the 1922 stone wall. The 1922 deed calls for the division to be 'along the existing stone wall,' and the wall's position is corroborated by (1) the 1898, 1910, and 1955 OS maps, all of which show a wall in the same position; (2) the 1960 boundary agreement, which explicitly records the wall as the boundary; (3) the 1995 planning application, which measures Oaklands' garden to 'the remnants of the historic stone wall'; and (4) the 2002-2020 aerial photography, which shows the wall in the same position throughout. The newly erected timber fence at Oaklands is approximately 0.7m east of the legal line along the central section, consistent with Mr. Rose's observation."

The analysis must show the surveyor's reasoning, not just the conclusion. A reviewer should be able to follow the logic from evidence to opinion.

8. Conclusion

A clear statement of the boundary:

• Each vertex (V1, V2, V3, V4, V5, V6) with its OSGB36 coordinates
• The length of each boundary segment
• The total boundary length (32.14m)
• A statement that the newly erected fence is 0.7m east of the legal line at the central section
• A recommendation: "The parties are invited to negotiate a boundary agreement reflecting the legal position, or alternatively, Mr. Rose may apply for a determined boundary under PG40 Supplement 5."

9. Surveyor certification

The certification section establishes the surveyor's accountability:

"I, Bhavesh Ramburn, MRICS, of Icelabz, confirm that this report has been prepared in accordance with the RICS Boundaries Guidance Note, 4th edition (2022), and the Land Registration Act 2002. The opinions expressed are my professional opinion based on the documents listed in Section 4 and the physical evidence described in Section 6."

The certification is signed and dated, with the RICS membership number.

10. Appendices

• Appendix A: Survey plan at 1:500 with North arrow and scale bar
• Appendix B: Coordinate schedule (OSGB36 eastings, northings, heights)
• Appendix C: Photograph register (47 numbered photographs with captions)
• Appendix D: Title deeds (key extracts only)
• Appendix E: Historic OS maps (key extracts only)
• Appendix F: Methodology statement (instrumentation, accuracy, control network)

Common pitfalls (and how to avoid them)

From the RICS 4th edition and 15+ years of practice:

• Don't omit the executive summary. Readers who skim the report should be able to understand the opinion in 30 seconds.
• Don't bury the conclusion. Put the opinion up front; the analysis supports it.
• Don't rely on a single source of evidence. Triangulate with at least three independent sources.
• Don't ignore inconvenient evidence. A surveyor who dismisses evidence they don't like is vulnerable to challenge.
• Don't sign without reading the entire report. The signature commits the surveyor professionally; every word must be checked.
