The T-Mark Fence Ownership Problem
Why Your Title Plan Has No T-Marks Showing Who Owns the Fence
Millions of English and Welsh homeowners check their HM Land Registry title plan and find no T-marks showing who owns the fence. This is not a mistake — it is the result of a systemic gap created during a century of property registration. Here is why it happened, and what you can do about it.
The Short Answer
T-marks showing fence ownership were recorded in original conveyance deeds when plots were first sold. When those properties were later registered at HM Land Registry, the T-mark wording was only transferred into the title register if the conveyance deed expressly referred to it and the solicitor specifically requested the transfer. In the vast majority of cases, this step was not taken. The T-marks remained in the paper deed — and were never registered. For millions of properties, they are gone from the accessible public record entirely.
This is not a Land Registry error. It is a consequence of how the 1925 registration system was designed — and how it was operated in practice by the legal profession for over 65 years.
An original conveyance deed — the document where T-marks and fence ownership obligations were recorded before registration.
The legal mechanism was sound in principle: a conveyance deed would state something like “the purchaser shall maintain the boundary marked T on the filed plan”, and that wording, if lodged and specifically requested, would appear in Section A or Section B of the title register. But the mechanism depended entirely on the conveyancing solicitor completing every step — and most did not.
What T-Marks Were Designed to Do
T-marks are symbols placed on boundary lines in deed plans. The convention is simple: the cross-bar of the T sits on the boundary line, and the foot of the T extends into the land of the owner who is responsible for maintaining that boundary feature — the fence, wall, hedge or ditch.
The intended flow: T-mark drawn on deed plan → deed text expressly references it → solicitor lodges at HMLR → wording appears in title register.
When a housing developer divided a large plot into individual residential plots in the mid-20th century, the standard practice was to draw up a layout plan and assign T-marks to each boundary. This would tell the buyer of each plot which fences they were responsible for erecting and maintaining. The system was practical, legally sound, and widely used by solicitors and developers alike.
The T-mark system was designed to run alongside — and feed into — the title registration system. In practice, the design depended on a chain of steps that was rarely completed in full.
To be legally effective, a T-mark required:
- The T-mark to be drawn on the deed plan
- The text of the conveyance deed to expressly refer to it (e.g. “to maintain the fence marked T on the plan hereto”)
- The deed and plan to be lodged at HM Land Registry on first registration
- The solicitor to specifically request that the T-mark wording be entered into the title register
It was step four — the specific request — that was routinely missed.
The 1925 Act & How Registration Worked
The modern system of land registration in England and Wales was established by the Land Registration Act 1925, which came into force on 1 January 1926. The Act created HM Land Registry as the central record of title, replacing the old system of private title deeds that had been passed between owners for centuries.
Compulsory registration was rolled out county by county from 1925 to 1990. Properties outside the registration area remained on unregistered title — and their T-marks stayed in paper deeds.
However, the 1925 Act did not immediately require all land in England and Wales to be registered. Instead, compulsory first registration was rolled out gradually:
- 1925: Middlesex and parts of London designated as the first compulsory registration areas
- 1926–1960s: Gradual extension to major urban areas — Greater London, Birmingham, Coventry, the industrial towns
- 1970s–1980s: Continued rollout across the rest of England and Wales, county by county
- 1 December 1990: Compulsory first registration extended to the whole of England and Wales
This meant that for the majority of England and Wales, a property only had to be registered when it changed hands on a qualifying disposition — typically a sale. Until then, it remained on unregistered title, with ownership proved by a bundle of paper deeds dating back at least 15 years (reduced from 30 years by the Law of Property Act 1925).
Unregistered Title and the Paper Deed Chain
During the decades before compulsory registration reached their area, millions of properties changed hands entirely outside the Land Registry system. Each sale was effected by a new conveyance deed, which referred back to previous deeds. T-marks in those deeds were known to the solicitor who held the deeds — but nowhere else.
When the property was eventually registered for the first time — often because it was sold after 1990 — the solicitor submitted the deeds to HMLR. The title register was created from what the solicitor submitted and specifically asked to be recorded. T-marks were almost never specifically requested for registration. They were left in the filed documents.
Why the Records Were Not Carried Forward
Under the Land Registration Act 1925, transferring T-mark information from a conveyance deed into the title register was an optional step that required the solicitor to make a specific application. There was no legal obligation to do so. The register recorded what the solicitor submitted and asked for — nothing more.
Pre-digital conveyancing: title deeds were physical bundles held by solicitors, transferred at each sale. T-mark details lived in these documents — and rarely made it into the register.
Several practical factors combined to make T-mark omission the norm rather than the exception:
1. The Deeds Were Considered Sufficient
At the time, the prevailing view in the legal profession was that lodging the deed plan at HMLR was enough. If a future buyer wanted to know about T-marks, they (or their solicitor) could inspect the filed documents. The register was never intended to be a comprehensive summary of every covenant and obligation in every historical deed.
2. No Standard Practice for T-Mark Requests
There was no established checklist or requirement to review each deed for T-marks and make a specific request. Different firms had different practices. In the mass-market residential conveyancing of the post-war era — when hundreds of thousands of new properties were built and sold annually — there was little time and no incentive to add this step to an already complex registration process.
3. The Buyer’s Interest Was Already Protected (At the Time)
A buyer who received their conveyance deed had a document that expressly stated their fence obligations. At the point of purchase they knew. The problem only emerged later: when the deed was lost, when the property changed hands again without proper investigation of the deed bundle, or when the question arose between neighbours 30 or 40 years later and neither party had access to the original deeds.
4. The Mass Housing Rollout
The decades from the 1930s to the 1970s saw the construction and sale of millions of new homes across England and Wales — council housing, private estates, post-war rebuilding. Each of these properties had conveyance deeds drawn up by solicitors working under time pressure, often using standard forms that may or may not have included T-mark language. The sheer volume meant any gap in practice was multiplied millions of times over.
The Scale of the Problem
HM Land Registry currently holds title records for over 26 million registered properties in England and Wales. Of these, the majority are residential titles that were first registered between the 1960s and 2000s — precisely the period when T-mark transfer was routinely omitted.
No retrospective exercise has been carried out to identify and register missing T-marks. The Law Commission’s 2016 review of the Land Registration Act 2002 acknowledged ongoing problems with boundary data but made no specific recommendation for recovering historical T-mark records. The gap, for the most part, is permanent — unless individual property owners take specific steps to recover or create the records.
The absence of T-marks does not mean there is no answer to the fence ownership question. It means the answer cannot be found in the registered title alone. The filed documents, physical conventions, and common law presumptions may all provide evidence. See What This Means For You below.
A Timeline: 1925 to Today
Creates the modern title registration system. Compulsory first registration applies initially to Middlesex and parts of London only. The rest of England and Wales remains on unregistered title — T-marks live exclusively in paper conveyance deeds.
Millions of residential properties built and sold across England and Wales. Conveyance deeds include T-mark plans. Compulsory registration spreads to major urban areas but the majority of the country remains unregistered. T-marks accumulate in solicitors’ deed bundles nationwide.
For the first time, every sale in England and Wales triggers compulsory first registration. When registered, the T-marks from the conveyance deed are only entered into the register if the solicitor specifically requests it. In the vast majority of registrations, they are not requested and remain only in the filed documents.
Introduces a statutory framework for works to party walls and boundaries, partially addressing the absence of clear ownership records in a practical context. Does not create or restore any T-mark records.
Replaces the 1925 Act. Codifies the general boundary rule under Section 60 — title plans show approximate, not exact, boundaries. Introduces the determined boundary process (s.60(3)) for the first time, allowing a property owner to apply for the exact boundary position to be fixed and registered. The T-mark gap is acknowledged but not retrospectively corrected.
Court of Appeal confirms that maintenance responsibility and ownership are legally distinct concepts. A covenant to maintain a fence does not transfer ownership of it. Clarifies the legal framework but does not address the missing T-mark problem.
Confirms ongoing difficulties with boundary data in England and Wales. Recommends improvements to the determined boundary process. Does not propose any retrospective exercise to recover lost T-mark records from the pre-2002 registration era.
England and Wales has the world’s most complete land register — but fence ownership records remain absent from the vast majority of registered titles. The gap from a century of registration practice is permanent unless individual property owners take active steps to investigate and register the position.
What Changed With the Land Registration Act 2002
The Land Registration Act 2002 replaced the 1925 Act entirely and brought significant reforms. It did not, however, solve the T-mark gap — but it gave property owners better tools to work around it.
The General Boundary Rule — Section 60
Section 60 of the 2002 Act formally codified what had long been the practical position: the boundary shown on a title plan indicates only the general position of the boundary — it does not determine the exact legal line. The red edging on a title plan has a physical thickness that can represent several inches or more on the ground. This rule applies to every registered title in England and Wales, regardless of whether T-marks are present.
The Determined Boundary — Section 60(3)
For the first time, the 2002 Act created a formal mechanism for fixing the exact boundary position. Under Section 60(3), a registered proprietor can apply to HMLR to have a determined boundary registered. This requires:
- A detailed plan prepared by a RICS-accredited boundary surveyor
- Evidence of the exact boundary position (documentary, physical, or agreed by both parties)
- HMLR’s approval — or the First-tier Tribunal (Property Chamber) adjudication if the neighbour objects
A determined boundary replaces the general boundary for the affected section of the register. It is permanent and binding on all future owners. However, it is relatively expensive and rarely used — primarily in contentious cases where a specific disputed point must be resolved.
Under s.60 LRA 2002, the red boundary edging is a general position only. The line has a physical width that can represent several inches on the ground — it is not the exact legal boundary.
HMLR Practice Guide 40
HMLR’s Practice Guide 40, updated following the 2002 Act, is the authoritative guidance document for boundary matters. It explicitly acknowledges that T-marks on deed plans without corresponding register entries have no legal force, and that the absence of T-marks from the register is common and not indicative of any error. It confirms that the filed documents should be examined where the register is silent on boundary responsibility.
The Bodies Involved Today
Several organisations play a role in the framework that has developed in response to the absence of comprehensive fence ownership records.
HMLR maintains the title register and title plans for all registered land in England and Wales. It holds the filed documents from first registration — including the original deed plans that may contain T-marks not entered into the register. Applications for boundary notes, determined boundaries, and title register updates are made to HMLR.
The Land Registration division of the First-tier Tribunal hears disputes about registered land, including contested determined boundary applications and boundary ownership disputes. It replaced the Adjudicator to HM Land Registry in 2013 and is less expensive than the High Court — though still a substantial undertaking.
RICS-chartered boundary surveyors prepare expert reports combining documentary evidence (title plans, deed plans, historical Ordnance Survey mapping) with precise physical measurement on the ground. Their reports are used in mediation and tribunal proceedings. RICS also operates a specialist Boundary Disputes Mediation Service.
Boundary agreements, determined boundary applications, and filed document investigations all require a solicitor with property dispute experience. The Law Society’s solicitor search tool covers England and Wales. Legal advice is particularly important if a register update or formal boundary agreement is needed.
The Law Commission reviews and proposes reforms to land registration law, including boundary provisions. Its 2016 report on the Land Registration Act 2002 acknowledged deficiencies in boundary data and recommended improvements to the determined boundary process, though no retrospective T-mark recovery exercise was proposed.
Where works are proposed to a party wall or structure astride the boundary, the Party Wall etc. Act 1996 governs the process. Party wall surveyors are appointed to oversee the works and resolve disputes. They operate independently of HMLR and the tribunal system, under the framework of the 1996 Act.
Check Your Filed Documents
Your original deed plan — held by HMLR as a filed document — may contain T-marks that never made it into the register. Order your Official Copies and filed documents to check the full picture.
Order Title Documents →What This Means For You
If your title plan has no T-marks, you are in the majority. The absence of T-marks does not leave you without options — it means you need to look beyond the title plan to establish the position.
Order Your Filed Documents from HMLR
The original deed plan lodged at first registration may contain T-marks that were never copied into the register. File references are listed in the title register under the entries that refer to “the filed plan”. Order these through HMLR’s document service. If T-marks are found, a solicitor can apply to have the register updated.
Check Your Neighbour’s Title Documents Too
Occasionally T-marks appear on one neighbour’s title but not the other’s. Ask your neighbour to check their own title plan and filed documents. If T-marks are found on their side allocating responsibility to you (or to them), that is meaningful evidence even without a register entry on your own title.
Apply Fencing Conventions and Common Law Presumptions
Where documents are silent, physical building conventions (post orientation, closeboard face direction) and common law presumptions (hedge and ditch rule) provide a starting point. These are not legally binding but are persuasive evidence and a useful basis for a direct conversation with your neighbour.
Read the fencing conventions guide →Agree a Formal Boundary Agreement
Where both neighbours accept the boundary position, a solicitor can prepare a boundary agreement — a document that records the agreed position and can be lodged at HMLR to update the register. This is the simplest and least expensive way to create a permanent registered record of fence responsibility going forward.
Apply for a Determined Boundary
Where agreement cannot be reached, a RICS-accredited boundary surveyor can prepare an expert report and you can apply to HMLR for a determined boundary under Section 60(3) of the Land Registration Act 2002. If the neighbour objects, the matter goes to the First-tier Tribunal (Property Chamber). This is the most robust but most expensive route.

T-marks indicating fence ownership were recorded in original conveyance deeds, not automatically transferred into the Land Registry title register. When properties were registered, solicitors were required to expressly request that T-mark wording be entered into the register. In the vast majority of cases this step was omitted. For millions of properties, the T-mark information remains only in the filed documents — the original deed plan lodged at HMLR — or in deeds held by solicitors that were never lodged at all.
T-marks from the original conveyance deed may still exist in the filed documents held by HM Land Registry — the documents lodged at first registration. These are separate from the current title plan. You can order the filed documents from HMLR to check whether T-marks were included in the original deed plan. If the property was sold multiple times before registration, earlier deeds may have been lost entirely.
You can order the filed documents from HMLR to check for T-marks in the original deed plan. If T-marks are found there, a solicitor can apply to have the register updated. If no T-marks exist in the filed plan, a formal boundary agreement with your neighbour — lodged at HMLR — can create a new registered record. A determined boundary application under Section 60(3) of the Land Registration Act 2002 is also available where agreement cannot be reached.
Not exactly. Under the Land Registration Act 1925, it was the responsibility of the applicant’s solicitor to ensure T-mark wording from the conveyance deed was carried forward into the register. HMLR would not add T-marks automatically — they relied on the solicitor to submit the correct application. The systemic gap is the result of routine solicitor practice over several decades, not a Land Registry administrative failure.
First order your filed documents from HMLR to check whether the original deed plan contained T-marks. Also ask your neighbour to check their title documents. Where no T-marks exist on either title, the boundary is generally treated as a party boundary — jointly maintained by both owners. A RICS boundary surveyor or solicitor can help formalise the position through a boundary agreement lodged at HMLR.
The 2002 Act improved the legal framework — codifying the general boundary rule, creating the determined boundary process, and establishing Practice Guide 40 as authoritative guidance. However, it did not retrospectively recover or register the T-marks that were omitted during the 1925–2002 era. The underlying data gap from that period remains. The 2002 Act gives property owners better tools to address the gap going forward, but the historical records that were not registered cannot be recreated from the register alone.
