Desktop Study Walkthrough: A Hypothetical Boundary Survey Scenario

The scenario

Two neighbouring properties in a suburban setting have a boundary dispute. Rose Cottage (owned by Mr. Rose) and Oaklands (owned by Mrs. Oak) share a boundary along the eastern edge of Rose Cottage's garden. The dispute is about a newly erected timber fence at Oaklands, which Mr. Rose believes is 0.7m east of the legal boundary (encroaching on his land). Mrs. Oak claims the fence is on the legal line.

The surveyor is instructed jointly by both parties to act as a Single Joint Expert (SJE) and produce a binding determination.

This walkthrough follows the seven-step desktop study process that precedes the site visit. By the end, the surveyor has built a robust forensic profile of the boundary.¹

Step 1: Order the HM Land Registry title plan and register

The surveyor starts by ordering the official copy of the register of title for both properties (Rose Cottage title BD123456 and Oaklands title BD789012) and the corresponding title plans in PG40 format.²

For Rose Cottage (title BD123456), the register shows:

• Registered owner: Mr. Rose (since 2018)
• Tenure: Freehold
• Edition date: 18 March 1995
• The property is shown edged red on the title plan

For Oaklands (title BD789012):

• Registered owner: Mrs. Oak (since 2010)
• Tenure: Freehold
• The property is shown edged blue on the title plan

The title plans show the general boundaries in red (for Rose Cottage) and blue (for Oaklands). The disputed boundary is the line where the red and blue edges meet.

Step 2: Read the title plan

The surveyor plots both title plans at the same scale and overlays them. The general boundary between the two properties is the line where the red edge of Rose Cottage meets the blue edge of Oaklands.

The title plans are at 1:1250 scale. The disputed boundary is approximately 32m long. The boundary is shown as a single straight line, with no monumentation, no dimensions, and no calls ("along the wall" or "to the oak tree" — none of that).

This is the general boundary rule in action: the title plan gives a rough line, not an exact line.³

Step 3: Order historic conveyances

The surveyor orders the historic chain of title for both properties back to the root of title (minimum 15 years, ideally further).

For Rose Cottage:

• 2018 conveyance (current owner)
• 1995 conveyance (previous owner, same family)
• 1960 boundary agreement (see Step 4)
• 1922 conveyance (root of title)

For Oaklands:

• 2010 conveyance
• 1985 conveyance
• 1922 conveyance (same root of title as Rose Cottage)

The 1922 conveyance is the same document — Rose Cottage and Oaklands were originally one parcel of land sold off in 1922. The 1922 deed is the key piece of evidence.

Reading the 1922 deed carefully:

• The deed plan shows the parcel with a hatched line marked "division line" between the eastern and western halves
• The deed text reads: "All that parcel of land... divided by the existing stone wall running from the oak tree at the north to the stream at the south"
• The deed gives dimensions for the total parcel (80m × 40m) but no dimensions for the division line itself

This is a critical finding. The 1922 deed says the division line follows the existing stone wall. The wall is a physical feature from 1922, and the law says the wall controls.⁴

Step 4: Search the charges register for boundary agreements

The surveyor searches the HM Land Registry charges register for any registered boundary agreements on either title. The search returns a single hit: a 1960 Boundary Agreement between the previous owners of both properties, registered as a land charge.

The 1960 agreement:

• Recites that the 1922 division line was "the line of the stone wall"
• Records a minor adjustment at the northern end (the wall was rebuilt 0.3m east of the original position in 1958)
• Records an explicit agreement that the southern portion of the boundary follows the original wall foundation

The 1960 agreement is the smoking gun: both previous owners acknowledged, in writing and on the register, that the boundary was the stone wall (with the 1958 adjustment at the north).

Step 5: Download historic Ordnance Survey maps

The surveyor downloads the 1:2500 County Series OS maps for 1898, 1910, 1938, and 1955 from the National Library of Scotland archive, plus the current 1:10000 OS map from the OS Data Hub.

On the 1898 map, a hatched line representing a wall is clearly visible in the exact position of the modern 1960 agreement line. The wall appears on every historic map from 1898 to 1955, in the same position.

This is independent corroboration: the wall has existed as a boundary feature for over 100 years, in the position the 1960 agreement records.⁵

Step 6: Review aerial photography

The surveyor reviews Google Earth Pro historical imagery from 2002 onwards. In 2002, the wall is clearly visible as a low stone structure. By 2015, the wall is partially obscured by vegetation but still traceable. By 2020 (two years before the dispute), the wall is gone — presumably demolished by Mrs. Oak's predecessor.

The aerial photography confirms: the wall was there, and it was in the position the 1960 agreement records.

Step 7: Cross-reference with local planning history

The surveyor searches the local council's planning portal for any past building applications related to either property. A 1995 planning application by the previous owners of Oaklands to build a garden shed includes a site plan that explicitly measures the width of the Oaklands garden to the "remnants of the historic stone wall."

This is corroborative evidence: the previous owners of Oaklands acknowledged the wall as the boundary when they applied for planning permission.⁴

Conclusion of the desktop study

By the end of the desktop study, the surveyor has built a robust forensic profile:

• The original intent (1922 deed): division along the "existing stone wall"
• Independent corroboration (1898, 1910, 1938, 1955 OS maps): wall in the same position
• Documentary evidence of a written agreement (1960): wall is the boundary, with minor northern adjustment
• Corroborative planning history (1995): previous owners of Oaklands acknowledged the wall

The surveyor is now ready to visit the site. The field visit is no longer a blind measurement exercise but a targeted recovery mission to find the remnants of the wall and tie them into the modern mapping grid.
